CHAPTER 11 : PLANNING PROPOSALS The planning proposals for the DNH ODP-2021 are briefly described here in terms of planning norms & standards adopted and major land use zones provisioned. For details of the same PLU map are to be referred.

11.1 Planning Zones For the purpose of devising individual land uses, planning zones were proposed where in the areas were consolidated into a single zone and redistributed according to the population projections into the villages. Five planning zones were allocated with 13 planning sectors in contrast to the patelad level for the purpose of required land use for different uses. The zones were divided into north and south based on River Damanganga that flows between the two zones. Planning zone I, II and planning zone V have three planning sectors (A to C, D to F and I to K) with Silvassa Amli UA, and Dadra as primary urban areas and Rakholi as a growing industrial area. Planning zones III and IV are divided into three sectors each. Each of these planning sectors have been given one nodal village which will become the focal point of that planning sector. The zones are allocated based on administrative boundaries, geographical/geological features, functional hierarchy and potential etc.

Planning Sector - M Mandoni Bedpa, Bensda, Chinsda, Khedpa, Mandoni, Sindoni, Vansda

11.2 Residential Use The overall growth in population of the territory in the next 20 years shall not exceed 10 to 12 lakhs 10-12 lakhs, differential FSI at this stage shall not be necessary which is based on differential density. Therefore it was recommended that there is no need to micro zone the residential zones in to sub zones based on density. There can be one Residential zone with uniform density and FSI.

11.3 Mixed Use Mixed land use comprising Residential and commercial is allocated where the road abutting more than 12meters within the Residential zone only.

11.4 Commercial Use Commercial use encompasses the mixed land use that is allocated within the Residential zone or in Industrial zone where the road abutting 18meters or more, district commercial centres which are purely commercial enclaves are provided with formal shops/showrooms, restaurants etc which works like a mini central business district.

11.5 Informal Sector and Hawking Zone Informal sector shopping areas are marked inside the district commercial centres for hawking and other activities. Informal sector areas for commercial use and hawking zones are to be separately identified by the urban local bodies in consultation with the PDA. However no hawking zones shall be allowed in a road which is less than 18m. In roads beyond 18m the hawking zones shall be identified on one side of the road by leaving a buffer of minimum 3m between the road and end of the ROW. Further no hawking zones shall be allowed in a radius of 15m from any of the junctions connecting a road of 18m and above.

11.6 Public & Semi-Public (PSP Use)

11.6.1 Educational

Facilities under the Educational use include Anganwadi, Mini Anganwadi, Pre-Primary School, Nursery School, Senior Secondary, Higher Secondary, School for


186

Handicapped, College, Technical Educational Centre, Technical Centre, Engineering Colleges etc The norms followed for calculation of educational facilities are UDPFI guidelines 1996, GoI Norms for setting-up Aanganwadi is 1 per 700 persons, and for Mini-Aanganwadi is 1 per 150 to 300 persons in Rural Areas, while Master Plan for Delhi - 2021 provides for 2 Aanganwadis per 5000 Population at Housing Cluster level, Socio-Economic Survey, 2008 (while as per secondary data in 2008 the same is derived as 10.68%), Government of Maharashtra The following is the context of Distance Norm: Primary School at the rate of 1 No. per 1 km. radius from habitation (Sarva Shikha Abhiyan - SSA Norm) is followed, and customised in the Patelads having Hilly Area - Randha / Dudhani / Mandoni upto average 0.85 km. radius and no school could be thought off for Kothar as the area gets under submergence and may be Vaghchauda & Kothar may have a single school located at Vaghchauda/Medha to meet their population requirements as feasible. From School For Handicapped(SFH) onwards to Engineering College the facilities are at higher level, and have been calculated suitably either at city level or planning zone level based on population size and availability of contiguous land [e.g. EC is suggested at Dhapsa in Planning Zone -II / Planning Sector - B (Naroli Patelad]. A gap for the current year’s requirement has been calculated based on the existing Educational facilities, population and norms. The future requirements for educational facilities were calculated based on the projected population for the years 2011 and 2021. However, the objection and suggestions received from the general public, the Technical Committee felt that the provision is required only in those area areas which are urbanized and / or in the stage of urbanization. All the Government lands has considered for the Public and Semi public purpose.

11.6.2 Health-Care

Facilities under Health Care include Health Sub Center(H-SC), Primary Health Center (PHC), Dispensary(DSY), Community Health Center(CHC), Poly Clinic(PC), General Hospital(GH), Intermediate Hospital (Category-A)(IH), Intermediate Hospital (Category-B), Nursing Home / Child Welfare & Maternity Centre(NH), Veterinary Hospital(VH), First Aid Veterinary Centre / Veterinary Dispensary(FAVC/DSY).


187

Since most of the current higher level health-care amenities exist in two planning sectors, equitable distribution of the same in overall PA till 2021 is attempted based on functional hierarchy/population. From Community Health Centre/Poly-Clinic onwards to the Hospital, the health care facilities are at higher level, and have been calculated suitably either at city level or planning zone level based on population size. A gap for the current year’s requirement has been calculated based on the existing Health care facilities, population and norms. The future requirements for Health care facilities were calculated based on the projected population for the years 2011 and 2021.

11.6.3 Socio-Cultural

List of Socio Cultural Facilities include Community Room (CR), Community Hall/Library (CHL), Recreational Club (RC), Music, Dance & Drama Theatre (MDDC), Meditation and Spiritual Centre (MSC), Socio Cultural Centre (SCC) and Religious Sites (RS). Since most of the current district level/community level/sector level (considering hierarchy as defined in UDPFI Guidelines for size of population of these levels) socio-cultural facilities seem limited. Equitable distribution of the same in overall PA till 2021 is attempted based on functional hierarchy/population. The SSC level facility is of the higher level, and has been calculated suitably either at city level or planning zone level based on population size. A gap for the current year’s requirement has been calculated based on the existing Socio cultural facilities, population and norms. The future requirements for Socio cultural facilities were calculated based on the projected population for the years 2011, 2021 and 2021.

11.6.4 Other PSP Facilities

Other Public Semi Public facilities include Police Station(PSN), Police Outpost(POP), District Office(DOB) and Battalion, Police Line(PL), District Jail (1 Sub-District Jail currently exists in Silvassa)(DJ), Civil Defence & Home Guards(CDHG), Fire Station(FS), Sub Fire Station(SFS), Head Post Office(H-PO), Post Office (PO) Since most of the current district level/community level/sector level (considering hierarchy as defined in UDPFI Guidelines for size of population of these levels) other


188

PSP facilities seem limited equitable distribution of the same in overall PA till 2021 is attempted based on functional hierarchy/population. Some of the other PSP level facility is of the higher level (i.e. DOB, PL, DJ, CDHG, and HPO), and has been calculated suitably at district level, while others of subsequent lower hierarchies is distributed for planning zone level, based on population size. At present the Fire station (FS) area is double the requirement for a 200000 population. However, this would be consumed in due course on account of the already proposed expansion plan of the Department of Fire & Emergency services (DoF & ES), and hence the proposed count is 2 numbers of FS at the FS site at Amli. Also, whenever Airport site at Luhari as provisioned in RP-2021 and integrated in ODP-2021 is developed, the said facility would also have its SFS as per AAI requirements, and thus could be available after due AAI approval in case of any need of meeting additional fire fighting capacity required in the DNH region.

11.6.5 Distributive Facilities

The total quantum of distributive facilities have been worked out based on the UDPFI Guidelines, 1996 norms for petrol pumps / milk booths / LPG Godowns and based on the RBI norms for banks required, with due integration on account of the existing provisions observed in DNH. Refer above mentioned annexure on planning norms & standards and the calculation of requirements of distributive facilities. However, the siting of these facilities would depend upon individual requests from such agencies and necessary decision shall be taken in this regard by DNH-PDA with due consideration to landuse and development control approvals, prior to establishment of these facilities. Normally, the petrol pumps are permissible within the large commercial / industrial zones, milk booths are permissible within all the core land-use zones, LPG Godowns are preferred to be permissible away from habitation and may be located in industrial zones, and banks are permissible within all core landuse zones (except large regional headquarter type bank premises that may be normally permissible in commercial zones and/or in public & semi-public zone if the bank is government/nationalised bank).

11.6.6 Miscellaneous Facilities

Cremation ghat sites exist at various locations within DNH habitation. Firewood is the commonly used in cremation at such ghat type sites. As the population increases the requirement of firewood would also increase, which may lead to unauthorised felling of trees. For reducing wood consumption, and as the population in the horizon year


189

2001 is expected close to 10 lakhs, 1 electric crematorium is recommended in Silvassa urban area on the banks of river Damanganga to come-up by the end of last phase of implementation of this ODP as the population in the Silvassa Patelad / planning sector – B by then itself would be about 5 lakhs. The location of the current cremation site is suggested to be expanded and developed for the same. Since the share of population of Christian and Islamic faiths seem very low in number, as per their community requirements for a designated land for community cemetery/burial ground, appropriate size of land may be designated by DNH-PDA on case to case basis of such community cemetery/burial ground requests in the public & semi-public zones indicated in ODP’s PLU map / green zones along the river/stream banks as suitable. In the current situation, 1 site of Church graveyard/cemetery exists at the junction of Silvassa-Amli-Saily roads to further east of District Civil Hospital (VBCH). While for burial grounds (managed by Wakf Board, DNH) for population of Islamic faith, government land has been provided for at Silvassa and Khanvel (Rajya Sabha Report, May 2002).

11.7 Physical Infrastructure/Utilities

11.7.1 Water Supply

For the planning of water supply, guidelines from the Manual on Water supply and Treatment by the Central Public Health and Environmental Engineering Organization (CPHEEO), GoI are to be followed. The norms/criteria/parameters for planning and designs are provided in the manual.

The treatment will be for treating the raw water to drinking water standards as stipulated in the Indian standards Specifications.

An Integrated Water Management Plan for Dadra & Nagar Haveli has been prepared in consultation with all stakeholders and suggestions / comments of UT Administration. This plan envisages to use the potential of the water available from Madhuban Dam by constructing two intake wells, one each at Rakholi and Silvassa. The total cost of the project is approximately 100cr. This project shall take care of the present and future domestic and non-domestic (including industrial use) upto 2041. Hence the proposal of the management plan is integrated with the Outline Development Plan. Any overlapping or contradictory proposals with regard to water infrastructure, the water management plan shall be referred to and the contents and proposals in the said plan shall be final for all purposes


190

11.7.2 Sewerage System

For the planning of Sewerage, guide-lines from the Manual on Sewerage and Sewage Treatment by the Central Public Health and Environmental Engineering Organization (CPHEEO), GoI are followed. The norms/criteria/parameters for planning and designs are provided in the manual. 80% of water supplied at tap level is to be treated as the quantum of waste water generation.

The treatment will be for treating the sewage to effluent standards as stipulated in the Indian standards Specifications for disposal to inland surface waters. And as per the CPHEEO manual).The type of treatment will essentially consist of units like,

• Screening • Grit removal • Primary settling • Aeration • Secondary settling • Digesters • Sludge treatment • Recirculation system • Chlorine contact tank • Roads, Area lighting, drainage

The costs for the above are presented in the annexure in the construction costs rate sheet. The costs are for capacities from 1.00 MLD to 30.00 MLD for the conventional STPs.

The basis for the costs is the Schedule of Rates developed by the state level organizations in the neighbouring states Gujarat (GWSSB) and Maharashtra (MJP).These rates are comparable with recently completed Sewage Treatment Plants (STPs). Since the MJP rates are normally higher compared to GWSSB rates, the same have been adopted for broad cost estimation.

The area (approximate) required for the STP lay-out of different capacities is as follows. The area provided should be with gentle slope and preferably be rectangular as far as feasible.

Table 11-2: Area requirement for STP with different capacities Capacity (MLD) Area (Hectare) Capacity (MLD) Area (Hectare)

1 0.25 10 0.75


191

2 0.30 15 1.00

3 0.40 20 1.50

4 0.50 25 2.00

5 0.6

For remote areas package sewage treatment plants are suitable. Couple of such plant processes is as follows: Rotating Media Attached Growth Process (Rotating Bio Disc Contactor) and High rate Aeration Process. The plants are available with capacities from 500 KLD (0.5 MLD) and costs range for this capacity are between Rs 30.00 to 50.00 lakhs. Area required is about 150 m2 for such package sewage treatment plants.

Pumping Station In the sewerage system a pumping station is required in order to hydraulically limit the excessive sewer depths. The pumping station, depending on the collection-conveyance system lay-out is either located within the collection network and outside the STP complex, or located within the STP complex itself. If it is adjoining the STP and located within the STP complex, it will be an Influent pumping station. In the former case the length of the rising main is more and in case of later it is marginal. The cost of pumping stations in either case will have to be separately considered the area required for pumping station is from 50 m2 to 250 m2 for above referred system capacities in general. Norms provided in Master Plan for Delhi – 2021 are also referred apart from the geographical spread in DNH.

Provision of STP / CETP for DNH The treatment process in case of CETP needs to be selected considering precisely the quality and quantity of waste water generated. The waste water generation will be based on the stage wise industrial development. Hence the units of the CETP need to be designed in suitable modules which will match to the staged industrial development and waste water there by. This will avoid incidence of under utilization of the plant which may hamper smooth functioning of the plant.

In case of DNH where the industrial and urbanized area is located separately and has high population, separate STP (Domestic) and CETP (Industrial) have been planned. Whereas CETP (Domestic and Industrial waste) have been suggested for the areas that are together/mixed located regions, and the population is less.

In both the above cases the individual medium/major industries have to provide preliminary treatment to its waste water (Screening, Grit Removal, Oil and Grease removal) before discharging to the sewerage system leading to the CETP.


192

The proportion of domestic and industrial waste to be treated in a CETP is not normally specified. It will be the quality of industrial waste which will have to be monitored prior to the discharge in to sewers leading to CETP.

The level of treatment that wastewater is subjected should be determined by the purpose for which it is recycled. It can either be discharged in water bodies or reused for other purposes such as gardening, depending on the quality produced. However it should be treated up to certain minimum levels in order to free the water of harmful contaminants that pollute the receiving environment. The treatment process is a multifaceted task that needs to be planned and controlled in a sequential manner in order to meet the required discharge standards.

The broad cost for the CETP can be derived from the norms cost of the STP. Additional cost of 25% is considered for the CETP over and above the cost of STP. Cost of preliminary treatment to be borne by medium/major industries should be considered at 5% for that capacity. (For instance if an industry is contributing 0.25 MLD waste water to the CETP, cost of 0.25 MLD CETP is Rs 7.00 Lakhs + 25% i.e. Rs 8.75 Lakhs, the cost of putting preliminary treatment by the unit in its own premises is Rs 44,000/-)

Cost of CETP when tertiary treatment is proposed, additional 50-75% cost over and above the CETP cost be provided (i.e. STP cost + 25% for CETP primary and secondary treatment +50-75% for tertiary treatment).

In DNH at present no STP facility of exists even for the urban area of Silvassa & Amli census towns. Now an existing proposal is approved for implementation at for the above-mentioned urban area, and its STP is of 16 MLD capacity that would be located at Silvassa. Including these capacities for sewage treatment, by 2021 as per the ODP planning proposals considering the geographical spread, the following total capacities are suggested

* excludes Masat & Saily ^ includes Masat & Saily ** include suggested provision of package STPs, as feasible based on detailed technical study of topography/ground conditions during implementation) The total sewage treatment capacity of 184 MLD by the year 2021 (including the package STP capacities of 12 numbers of 0.5 MLD each) is a rounded off figure derived based on 80% of water supply being made available at tap level. Since the ideal situation of access to piped sewerage system in whole of DNH is tentatively attempted, however where not feasible due to small population and dispersed location septic tanks / waste digesters with energy recovery (as per GoI norms) could be encouraged. With the assistance of micro-finance institutions that may provide micro-credit to low income households for building, first pit latrines at in-house level to gradually being upgraded with flush latrines connected to in-house septic tank to community septic tanks (where in possibility of waste digesters with energy recovery could be explored).

Also, Community / Public Toilets are recommended where individual household level toilet facilities are not available at housing cluster level or slum / urban poor type habitation at the rate of 1 toilet per 4-5 Families/Households as per UDPFI Guidelines, 1996 or 1 toilet seat per 50 persons as per Draft National Slum Housing Policy, October 2001 as applicable, apart from some of those that could be required at general commercial use zones.

11.7.3 Storm Water Drainage

The storm water drainage system basically comprises network of drains for disposal of storm run-off to the natural water courses. With reference to developed area/habitations the drains are in three categories,

• Tertiary Drains (mostly road side drains/gutters) • Secondary drains (link drains between road side drains and primary drains)


194

• Primary Drains (Nallahs, Streams)

Storm Water Drainage System is primarily site specific in terms of its functioning and resulting problems. For DNH, two distinct topographical parts are clearly seen. The East, South-East and North-East parts are hilly terrain in nature with steep to moderate sloping terrain. The remaining area is comparatively gentle slopes/rolling terrain or plain terrain. More over the former part is less developed and virgin to some extent whereas the later is a fast developing/developed one. The storm water system scenario in the two regions is totally different and needs to be addressed accordingly.

In the following table, a preliminary analysis of the drainage system is presented.

Component Parameters East Region West Region

Primary Drain/Secondary Drain

Steep Slope • Drain flow smooth.

• No stagnation of water

• Erosion and scouring at the

bank and bed

Mild Slope • Stagnation occurs • Silting takes place

Habitation and population density

• Stretches of drains not encroached

• Encroachment affects the capacity of drain

• Obstruction due to dumping of waste, debris

Tertiary drains Development • Area scattered with natural drainage, and hence run off takes place without much hindrance

• Densely populated • Except in current urban

area, where some drains are observed, absence of complete road side drain network may result in flooding during high rainfall intensity

The proposals shall be confined to the inhabited part (urban/rural and industrial) of the DNH coverage area, with predominantly open drains in the hilly terrain area, and covered gutters/ piped storm water sewers in the habitable part. The actions required for a proper storm water drainage system would be:

Eastern Region


195

• Strengthening of primary drain sections to prevent erosion and scouring • Cross Drainage works on primary drains –Culverts, Bridges • Provision of road side drains at crucial stretches

Western region

• Augmentation of primary drain by de-silting, widening, deepening and improving its hydraulic capacity

• Cross Drainage works on primary drains –Culverts, Bridges • Provision of road side drains as gutters/ piped storm water sewers on all roads

on both sides • Maintain continuity of the system up to primary drains

For the costing of various units of storm water drainage no SOR is available. The cost proposals will have to be based on market (recently constructed works). WAPCOS report for storm water drainage estimation for Silvassa town and the PWD, E.E-II Division provided information on typical drainage cost on both sides of road per km is also referred.

The costs for the above are presented in relevant annexure in the construction costs rate sheet. For repairs/rehabilitation works 25% to 50% of the respective costs may be adopted. In the subsequent stage based on the surveys estimates can be prepared item wise.

For green storm water management, use of international best practice concepts like bio-swales within the road streetscape design shall be explored. Such bio-swales are said to be provisioned between the road carriageway edge on one side and the landscaped pedestrian pathway abutting the build-to-line on the other side. The bio-swale when as it is a formal longitudinal strip in roads of large ROW is a low level natural ground strip which is prepared on its top with a suitable mix of clay / gravel bed and planted with native grass, while the middle part of the said bio-swale strip carries an underground storm water piped sewer utility line. The top level of the storm water manhole grated cover is just below the top level of the road carriageway edge / pedestrian pathway kerb edge. This facilitates in the absorption of first precipitation that usually contains pollutants, and which thus mostly is likely to get filtered naturally through ground with minimal quantum of it being able to make to the storm water piper sewer to ultimately to any primary drains / river / stream. Only after the low level strip is filled with rain water, any overflow depending on the rain intensity would be able to make to storm water piped sewer, thus containing the storm water runoff discharge required to be managed through such formal built-type infrastructure arrangement. An informal shaped arrangement of bio-swales is also said to be


196

possible when designed within individual precincts of housing / other use precincts by integrating the same with the landscaping design.

11.7.4 Solid Waste Management

For the solid waste management and handling, the Guidelines to be followed are specified in the Notification of the Ministry of Environment and Forests, GoI, 2000, under the Environment Protection Act, 1986 and named as Municipal Solid Wastes (Management and Handling) Rules, 2000.

The Schedule II of the notification specifies management of municipal solid waste and covers the aspects as,

• Collection • Segregation • Storage • Transport • Process • Disposal

Schedule III stipulates Selection, Specifications, and Facilities at site.

Site selection to consider parameters like,

• Environmental issues • Approvals and clearances • Feasibility for phased implementation • Adequacy of area for future needs • Located away from habitation, water bodies, etc. • Buffer zone creation in land use planning during the development plan preparation

Main specifications include Compaction in thin layers, covering the waste at the end of each working day to the active portion of the landfill, Final Cover to minimize Infiltration and Erosion, Plantation, Closure and Post-closure care. Land cover minimizes the infiltration of precipitation and maintains an aesthetically acceptable landfill.

Daily cover is required to minimize leachate production from precipitation; eliminate direct access to the refuse by the vectors; and control fires, odours, and blowing litter. Wastes shall be covered immediately or at the end of each working day with minimum 10 cm of soil, inert debris or construction material till such time waste


197

processing facilities for composting or recycling or energy recovery are set up. Prior to the commencement of monsoon season, an intermediate cover of 40-65 cm thickness of soil shall be placed on the landfill with proper compaction and grading to prevent infiltration during monsoon. Proper drainage berms shall be constructed to divert run-off away from the active cell of the landfill.

After completion of landfill, a final cover shall be designed to minimize infiltration and erosion. It shall be sloped to promote runoff of precipitation from the landfill. The final cover shall meet the following specifications, namely:

a. The final cover shall have a barrier soil layer comprising of 60 cm. of clay or amended soil with permeability coefficient less that 1 x 10-7 cm./sec. Membranes like geomembrane/synthetic membrane could be used if they satisfy the requirements.

b. On top of the barrier soil layer there shall be a drainage layer of 15 cm. c. On top of the drainage layer there shall be a vegetative layer of 45 cm. to support

natural plant growth and to minimize erosion.

Facilities at landfill site include Fencing with gates, Waste inspection facility, Water and Electricity.

Transfer Station

For transporting the waste from city collecting centers/points to the disposal/processing site, a transfer station may be required in following conditions,

• The disposal site is located far away from the city say more than 6-7 km. • The internal road network is narrow and medium/big vehicles movement is not

possible.

In such cases the waste collected from the core town with smaller vehicles (rickshaws/tempos) is transported to a common point where it is unloaded and loaded in medium/big vehicles (Trucks/tractor trailers) and ultimately transported to the processing/disposal site.

The design/layout in such cases is site specific and often a simple and economical system can be provided. The factors that could affect the transfer station facility site layout and design are: amount of waste anticipated at the facility on a daily basis, recycling options, ingress / egress options, buffer zones, citizen’s waste drop off areas, and the local development control regulations.


198

For example if a spot/site in the town where a natural platform with level difference is available, with some civil work it can be developed as a transfer station. The site can be developed with a proper ramp, a platform 3-4 m above the road/ground level, sufficient for standing and small vehicle turning and space for big/medium vehicle on normal road.

Alternatively a regular RCC construction transfer station with frame structure can be provided. This however is costlier.

Following are the parameters (range) for municipal waste to facilitate calculation of the amount of waste generated, depth of landfill site required, etc.: Parameter Unit Value ConsideredPer capita kg 0.2 to 0.6 0.3 Composition Biodegradable % 40 to 60 40 Recyclable % 5 to 10 10 Non Biodegradable % 20 to 50 50 Density Tonne/m3 0.25 to 0.3 0.27 Recyclable waste includes paper, plastic, metal, glass etc. Segregation of this shall preferably be done at source.

The processing and disposal of solid waste is considered as per the chart below:

It is assumed that the first phase of the project will be commissioned in year 2011-12. Design stage for the system is considered as year 2021. For first stage of landfill it is year 2016 by end of second phase of ODP implementation. For landfill further required, modules of 5 year each can be added.


199

The estimated cost for the components of solid waste management can be worked out with market rates (for vehicles, litter bins), based on actual constructed works (e.g. landfill sites transfer stations).

For Landfill Sites and Transfer Stations the approximate costs (the costs do not include the cost of land) are as below:

Population for Year 2008 Year 2031

1 15000 23000

2 25000 46000

3 50000 76000

4 100000 152000

Broad costs of solid waste processing and landfill disposal for different capacities are worked out with the abstract as below based on market rates assumption:

Table 11-4: Broad cost and requirements of solid waste processing and landfill sites Population Waste Length Breadth Area Reqd Cost

(MT/day) (m) (m) (m2) (’000 Rs)

26000 7.80 85 55 4675 6265

200000 60.00 250 166 41400 36390

The quantity of solid waste transferred via transfer station depends on the town spread and lay out and it is approximately 30 to 60 percent of the total solid waste.

Transfer stations referred below are for population sizes:

• Type 1: Up to population of 75,000 persons • Type 2: More than 75,000 and up to 150,000 persons.

The approximate area and estimated costs as per market assumptions for a transfer station with respect to mode of vehicles used to transport waste to an either open natural site or a developed site is given below:

Composting of bio-degradable waste shall be encouraged in community lands for the areas that are spread out / difficult to access, with or without energy recovery as per GoI norms. Compost products like manure can be sold and generate economic benefits to the locals.

For the solid waste disposal landfill sites, the current quarry site at Khadoli being at a rather central location within DNH and already being in use with an initial allocation of 1 Ha. area if Survey No. 121 (part) is suggested to be expanded till it is utilised fully. While, the quarry site at Morkhal be given the last priority for such use. Any additional sites required may be located within any of the industrial zone. Such use provisions have been framed in the development control regulations. This arrangement shall be very well sufficient to meet the load of solid waste generated by 2031. However, the urban local body, currently SMC and others in future would have to have proper capacity building in terms of manpower and equipments to collect and dispose the quantum of solid waste generated.

The existing hazardous waste disposal facility i.e. Integrated Common Hazardous Wastes Treatment, Storage and Disposal Facility - ICHWTSDF for the UT of Daman & Diu (Daman part) and Dadra & Nagar Haveli being developed at Mota Randha village spread over 33 acres or 13.36 Ha. could be expanded by 1-1/2 times with the industrial growth. The capacity of this facility should be enough to handle the load of hazardous industrial waste, medical waste, any slaughter house waste, etc.

11.7.5 Power Supply

The Electricity Department, DNH has been providing the necessary power supply infrastructure in DNH as mentioned earlier in the existing status chapters, under the


201

CEA, GoI norms and master plan prepared for DNH for 2012 period. This includes the following already proposed power supply arrangements: • The power purchase agreement for additional power from the generations of

NTPC and other Central Sector Power Stations has been signed, and the additional power of 165 MW would be allocated to DNH vide this agreement in phased manner, with its summary given below:

TOTAL 165 MW

• Meanwhile, a GoI proposal for own electricity generation for UTs of DNH and Daman & Diu with a capacity of 500 MW / 1000 MW project as feasible in Gujarat (Vansi-Borsi, in Navsari district) as per the guidelines of CEA is in pipeline (OIDC and IL&FS SPV would follow up this process).

Based on the current levels of the electricity consumption per day in DNH for domestic use & industrial use and converting the same to per household consumption norms, it is observed that the figure derived is 3.60 KW per household i.e. a high figure (almost double when compared to the UDPFI Guidelines, 1996 norm of 2 KW per household per day) due to much higher %age of industrial landuse envisioned as per RP-2021 for DNH. Thus, this higher figure is used for broadly working out the total power demand at ODP level for DNH by 2021 to be adopted in general, except for those settlements where industrial use is not provisioned and where UDPFI Guidelines, 1996 norm is suggested for such broad power demand calculation. Thus, the overall power demand in DNH by 2021 is observed to be about 750 MW. This is almost double the figures of present power allocation to DNH of 385.66 MW during off-peak hours and 380.20 MW during peak hours, and actual power withdrawal of


202

DNH in the range of 370 MW to 400 MW (though the daily scheduled availability of power under the ABT regime ranges from 225 MW to 300 MW only). The progress on development of the above mentioned dedicated power plant for DNH and DD in future would affect the likely time-period when the power allocation from this plant would be made available to meet the power demand gaps by 2021 in DNH.

Also, based on the UDPFI Guideline, 1996 Norms / CEA, GoI norms as referred in the Master Plan for Delhi – 2021, the planning proposals for total infrastructure required / augmentation quantum for 220/66 KV and 66/11 KV electric sub-stations has been tentatively suggested after integrating the existing provisions in account. The Electricity Department, DNH may work out in detail its electricity supply related infrastructure requirements / revise above mentioned tentative provisions with respect to the population projections, geographical spread, transmission line required etc., at the time of implementation of DNH ODP-2021, in due consultation with DNH-PDA for necessary landuse and development control approvals. Note: From the perspective of the safety of the human life and built-up areas, the following needs to be ensured: 1. Suitable buffer zones (as per the buffer distance applicable as per the Electricity

Department norms) shall be enforced by DNH-PDA under the high tension transmission lines, and no development shall be permitted in such buffer zones, except green belt/zone or road crossings.

2. Underground provision of electricity supply network for safety / minimizing theft of utility line and power leakage from connections that tap electricity illegally for better performance of power distribution / visual aesthetics etc. should be undertaken by the DNH-PDA as part of detailed streetscape planning and Electricity Department, DNH for implementation in collaboration with other executing agencies of urban local body (currently SMC) / DP.

3. Any gas supply utility related infrastructure, when permitted by DNH-PDA shall be compatible from landuse and safety perspective, like the issue of distance from high tension electrical installations as per the safety norms of the concerned Gas Utility Company, buffer zone necessary around such gas installation for safety of other core landuse habitations, etc. including depending upon the type of utility layout – i.e. above ground or under ground, whether it requires separate land strip allocation or can be accommodated in a road ROW, etc.

11.7.6 Telecommunications

As per the UDPFI Guidelines, 1996 telecommunication capacities are to be planned for 10 landline connections per 100 persons. However, in the present times the


203

telecommunication service is also available through private sector significantly. Also, in the context of mode of cellular (i.e. mobile) communication being extensively used, norms for permitting erection of local small exchanges / Remote Subscriber Unit (RSU) need to be suitably derived at (when erected these should not be in line of sight to avoid any visual impacts along a streetscape / local landscape as far as possible, also should only have at the most a very low environmental impact if any, and shall have warning light arrangements if mounted on a tower if close to aviation ports). For the purpose of the broad demand calculations at ODP level by 2021 in DNG, the above-mentioned UDPFI Guidelines, 1996 norms is used, the planning proposals for total infrastructure required / augmentation quantum for telephone exchanges and local small exchanges / RSU has been tentatively suggested (by adopting the Master Plan for Delhi – 2021 norms) after integrating the existing provisions in account (i.e. 1 BSNL main exchange at Silvassa and Non-BSNL local small exchanges – 1 each at Dadra / Naroli / Khanvel / Kilavani / Dapada at present & at Athal / Rakholi / Surangi as already proposed). The concerned telecommunication service agency i.e. Department of Telecommunication / BSNL or Non-BSNL/Private Service Provider in DNH may work out in detail its telecommunication service related infrastructure requirements / revise above mentioned tentative provisions with respect to the population projections, geographical spread, cable line / service tower required etc., at the time of implementation of DNH ODP-2021, in due consultation with DNH-PDA for necessary landuse and development control approvals.

11.8 Traffic & Transportation

Interventions and proposals aiding the expansion of the population and urban footprint in DNH, at the same time catering to the travel demand are envisaged with the provision of adequate road network infrastructure through land reservation policy. These interventions are briefly described below and detailed out in the proposed landuse (PLU) map.

1) New Roads: The accessibility of all villages and within urban area is very high in DNH. Spatially all new residential/commercial areas, public & semi-public facilities and other utilities which have been proposed as a part of the Outline development exercise have been given proper access by the provision of new roads with ROW of 18 metres, 25 metres, 30meters and 35 metres based on the functional hierarchy and expected travel demands.

2) Naroli – Dapada – Velugam Byepass: A new highway has been proposed for traffic to move towards south DNH byepassing Silvassa specifically catering to Goods traffic. This will help in reducing congestion in Silvassa occurring


204

due to through traffic. The 35 M wide byepass starts from Naroli Village south of the existing state highway, traversing through kharadpada, Luhari, chikhali, surangi, apti ending at velugam. A connector arm from the bypass meets the proposed National highway near Dapada and Vasona boundary. However a proper feasibility study and Impact assessment studies should be carried out to finalise the alignment.

3) New Dadra – Silvassa Road/Byepass through Vagchippa: As a measure to decongest the existing Vapi – Silvassa road, parallel secondary alignment is proposed along both sides of the canal through Dadra Patelad with an total Row of 24 metre. This alignment joins ring road at Silvassa after passing through Vagchippa..

4) Ring road: A ring road in Silvassa needs to be constructed immediately as per the alignment already finalised. Further an outer ring road at a distance of 2kms approximately from the inner ring road is also proposed which needs to be developed. Tow other ring roads have also been proposed to byepass the Naroli and Khanvel Towns.

5) Road Over Bridge: Road Over bridges over all the streams, rivers are currently narrow than the approach roads, thus acting as traffic bottlenecks. Each of the Road over bridges need to be added in capacity, with a double bridge configuration. A double independent bridge configuration is required, so that if any one of the bridge gets damaged, the other bridge can be used for the mobility. Road Over Bridges near Pipariya Industrial Estate on Dadra - Silvassa Road and near Rakholi on Silvassa - Khanvel highway need immediate attention. A new two lane bridge must be constructed over Damanganga River at these two locations.

6) Junction Improvements: Silvassa junction, Khanvel junction, Samarvarni Junction need improvement by geometric redesign, and re-layout after proper physical survey of the junction/adjacent elements using total station method, etc.

7) Parking: Silvassa does not have any designated parking lots; Provisions have to been made in the plan for Parking Lots in developed areas of Silvassa. Stringent measures for provision of parking within the premises need to be enforced in all new developments as per the DCR.

8) Bus Depots & Terminals: There are no proper Bus Depots at Silvassa and Khanvel for the Intra-city Buses. Provision of New Bus Depot at Silvassa, Khanvel and Naroli has been made. however, there are scientific study has required to indetify proper locations for Bus Depot.


205

9) Integrated Freight Complex and Truck Terminal: In light of the Delhi Mumbai Industrial Corridor (DMIC) project, in which Vapi would become an important node of development, and which would also catalyse industrial development in DNH, At present, however the presently proposed Transport Nagar at Amli Village may suffice for the needs. A separate scientific study needs to be undertaken for the earmarking of other locations in DNH for the same purpose

10) Airport: A site for airport measuring about 80 Hectares (2000mts X300mts plus an additional 25 acres) has been proposed in the village of Luhari (including the area proposed in regional Plan 2007-21). As and when, an airport is required the site can be selected for the airport based on the technical and commercial feasibility. Thereafter the norms required for airport vicinity shall be enforced accordingly.

11) The new roads proposed in the ODP 2021 shall as far as possible cater to the growing needs and demand.

11.9 Recreational Since most of the current district level/community level/sector level (considering hierarchy as defined in UDPFI Guidelines for size of population of these levels) recreational facilities seem limited equitable distribution of the same in overall PA till 2021 is attempted based on functional hierarchy/population The Community level, District level, and City level P/G & PD facility are of the higher levels, and have been calculated suitably respectively as grouping of planning sectors, as grouping of planning zones, and as city level as a whole, based on population size. For District Level Planning Zones I & IV have been considered together (northern half of DNH) as these are separated by the Damanganga River & Reservoir from the other half (north-western & southern half of DNH). Banks of the river Damanganga have been proposed for waterfront development from Rakholi to Silvassa. A land acquisition process for Golf Course has reportedly begun at Talavali for 200 acres. However 32.50 Ha. seems available as per Survey No. 70, 4/1, 5/1 & 6/2 provided, and thus it can be considered as the District Park level requirement for the southern half of DNH. The proposal of RP-2021 in Mota Randha for RTZ with about 88 Ha. area and that of 2 small adjacent Sites to this RTZ site (1 at Mota Randha in Survey No. 265 & 1 at Nana Randha in Survey No. 5, both together seem to be available as about 12 Ha.), together have been retained as the City level Park requirement of 100 Ha. for DNH.


206

Though the formal provisions made at ODP level seem less in terms of recreational area i.e. sq.m. availability per person is less than 10 sq.m. normally recommended or in acres per 1000 persons is less than 3 acres normally recommended, the figure would improve when considering play area available in educational facilities, planting area as part of streetscape, scenic corridors along certain roads with green belts, further recreational provisions that would come at housing cluster level etc. Any discernible gap in formal provision, in real terms of DNH context does not really impact the availability of sufficient open spaces, as a lot of area would still remain under green zones of the Planning Area. As well as a large area of 20321 Ha. abutting developable area or interspersed with it in terms of forests area already exists and complements in availability of enormous natural space available in general (access is though limited to the citizens as per the forests departments' accessibility provisions to access forest resources) in the DNH overall territory.

11.10 Green Zones Green Zones G1 and G2 are based on the regional plan. Restricted Public/semi public uses have been proposed in specified areas of G1 and G2 zones of Regional Plan and may be used for complementary activities.

11.11 No Development Zones A buffer of 100 metres around all Wild life sanctuary has been marked as No development zone (NDZ) and no development of any kind will be allowed on such lands except where the authority may deem such development necessary for the overall welfare of the region
