1 INTRODUCTION:

1.1 GENERAL

1.1.1 Water has a unique place in all the renewable resources of the planet. Water resources of

a country constitute one of its vital assets. Where there is water, there is life and where

water is scarce, life has to struggle. It is essential to sustain all forms of life, food

production, economic development, industrial growth and for general well being. It is

impossible to substitute water for most of its uses.

1.1.2 Water supply scenario in India has considerably improved during last two decades.

Planning commission report states that in India water is supplied to about 85% of the

urban and rural population but the challenge is in providing 24x 7 services. The main

issue of concern is the pollution of available surface water sources and depletion of

ground water table due to over exploitation. In India, the primary responsibility for

providing drinking water and sanitation facilities in the country rests with the State

Governments, and, more specifically, the local bodies in the urban areas.

1.1.3 Haldia city is fortunate to have water supply system for both industrial and domestic

supply. Haldia Development Authority (H.D.A.) the nodal agency and Statutory

Authority in charge of development of urban and industrial infrastructure in the region.

HDA is actively encouraging implementation and maintenance of infrastructure projects.

One of the key infrastructure requirements of the region is availability of reliable and

quality water supply. Haldia is an important industrial town with a residential

population of 200,762 as per 2011 census. Presence of several important industries such as

Haldia Petrochemicals Limited , Mitsubishi (MCCPTA) , Indian Oil Corporation Limited,

Indian Oil Petronas Limited, Tata Power, Tata Chemicals, Exide Industries , South Asian

Petrochem Limited, Reliance Industries, Electro-Steel Castings, Bharat Petroleum

Corporation Limited and others have made it a major industrial hub.

1.1.4 Haldia is also an important logistics hub, having a large riverside port. Haldia Dock

Complex, an important part of Kolkata Port System, has an annual throughput of 128,470

TEUs in Container Freight Service (CFS). Presence of several large industries, a large


2

dock complex and a growing population has made Haldia an important hub in West

Bengal.

1.1.5 Haldia is in the process of being transformed into the most coveted industrial destination

in Eastern India. Hence, providing quality civic infrastructure and utility services has

emerged as a policy priority for Government of West Bengal. In order to achieve and

sustain this position, HDA has been working towards achieving of World class

infrastructure facilities in Haldia.

1.1.6 As part of its key obligation, HDA supplies treated water to industrial, commercial,

domestic & municipal consumers in and around Haldia town and Haldia Industrial Area.

For this purpose, it has set up a water treatment facility of 25 MGD capacity at Geonkhali

in 1992. In addition, there are fourteen (14) deep tube wells within the Haldia Planning

area to supplement potable water supply to the Booster Pumping station at

Chaitanyapur. The water treatment plant gets raw water from the Hooghli river through

an intake jetty, located close to the confluence of the rivers Rupnarayan and Hooghli.

This portion of the river is a tidal stretch, witnessing high and low tides twice in 24 hours

period. Turbidity reaches around 1600 NTU during monsoon. Because of proximity to

sea, the stretch suffers from high salinity level, which reaches more than 2000 ppm

during lean season of the year when there is no freshet in Hooghly and during high tides.

HDA mixes ground water drawn from 14 tube wells, at Chaitanyapur boosting station

before it is distributed to consumers. Also it has a 200 million gallon capacity of Pre-

Settling Tank, which receives raw water through three inlet channels. During low tide,

water quality is generally of acceptable level and salinity issue remains under control. So

by controlling intake flow of water, a proper mix can be achieved so that actual supply

does not get significantly affected by salinity problem. At distribution end, water supply

system consists of three boosting stations with semi underground reservoirs. The

boosting stations are located at Chaitanyapur, Basudevpur and at Hatiberia. Another

Pumping Station with reservoir is being constructed which is expected to be operational

in July, 2016. In 2005-06, augmentation of the old treatment facility was made by adding a

new 5 MGD filter to the existing 20 MGD capacity filters and by modification of the

existing clariflocculators with tube settlers at the periphery and Water Treatment facility

had been expanded to 25 MGD.


3

1.1.7 Construction and commissioning of new 25 MGD WTP over and above the existing 25

MGD had been operational since December, 2014. The new plant has separate intake

arrangement. It uses the existing raw water inlet channels (3 nos.) and settling tank of 200

million gallon capacity as a common facility. The new 25 MGD treatment plant with

semi-automated control system has been designed to supply water to Basudevpur

Boosting Pumping Station directly through a newly laid 900/1000 mm diameter D.I pipe

line through a bifurcation station, from where a separate pipe branches out and feeds

water to IOCL reservoir. HDA is now having at its disposal, combined water treatment

capacity of 52 MGD (50 MGD from water plants and 2 MGD from tube wells) for meeting

water demand of its valued consumers in Haldia Industrial Area.

1.1.8 In the year 2008, HDA entered into a Concession agreement with Haldia Water

Management Limited (HWML), a joint venture company of JUSCO and Ranhill Utilities,

Malaysia for construction of a new 25 MGD water treatment plant and the O&M of the

entire water supply network of Haldia for a period of 25 years. However for municipal

supply, HWML delivered bulk water to different zones of Haldia Municipality to its

reservoirs. The distribution network of Haldia Municipality is maintained by Haldia

Municipality. The agreement between HDA and HWML was in effect since November

2008 to March-2013. Since April, 2013 the Haldia Water Supply Project is being operated

and maintained by Haldia Development Authority.

2.0 HYDROGEOLOGY & TOPOGRAPHY

Haldia is a rapidly developing urban centre in southern part of Purba Medinipur district

of West Bengal. It is located at latitude 22º 03´ N and longitude 88º 06´ E. It is a major

riverine port and an industrial city of Eastern India. Haldia is located at the confluence of

River Haldi and River Hoogly and is 56 Nautical miles downstream of Kolkata. Haldia is

well connected by South-Eastern railways and by NH 41 and NH 6 with rest of India.

Haldia municipality covers a total area of 104.9 sq. km, comprising 26 wards. Haldia is

situated close to the confluence of River Hoogly and Haldi. River Hoogly, a distributary

of River Ganga, is the main drainage course of the area. Both Hoogly and Haldi are

estuarine in nature and experience tides. The rivers are fed mostly by upland discharge,

which is maximal during monsoon. Tides are diurnal with mean range during spring

being 4.90 m. Average velocity during tidal cycle is 1.75 m/sec. The soil in Haldia has a


4

characteristic high water holding capacity. In rainy season, the water level rises to the

maximum of 1.50 m and during summer it falls to a depth of 5.5 m from the ground level.

Due to the high salinity of the Rivers Hoogly and Haldi in stretches near Haldia, they are

not suited for water supply. The required water for domestic and industrial water supply

is obtained from an upstream point at Geonkhali where Roopnarayan River meets River

Hoogly.

The general topography of Haldia town, which is spread over an area of 104.9 sq. km, is

relatively flatter having general gradient from North to South and South to West. The

river Hoogly meandering in a direction of South West to East flows by the Southern

boundary of the Haldia Municipality.

3.0 CLIMATE

Haldia has a moderate tropical climate with winter temperatures ranging from a low of

around 7 degrees Celsius to a high of 22 degrees Celsius. Summers can be very hot and

humid. Usual summer temperatures in May, the hottest month, range from a low of 24

degrees Celsius to high of around 39 degrees Celsius. Rainfall is heavy during monsoons,

and the rainy season spans between the months of June and September. The annual

rainfall is about 1600 mm.

4.0 PROJECT DESCRIPTION:

Old Water Treatment Plant has been renovated and new water treatment of equal

capacity has been in operation since December, 2014. Sufficient water supply network

with water reservoirs, pump houses and pipeline network have already been created.

The details are:

• Old 25 MGD Water Treatment Plant: It consists of intake jetty, intake channels, raw water

pump house, presetting tanks, settled water pump house, chemical house, flash mixers,

clarifloculators, Elevated storage reservoir, filter house, clear water reservoir, sludge

pump house, sludge ponds, laboratory and electrical sub stations etc.

• 25 MGD New Water Treatment Plant: New Water Treatment Plant of 25 MGD capacity

consists of intake jetty, raw water pump house, settled water sump and pump house,

chemical house, DAF house, clear water storage tank and clear water pump house,

chlorine room and electrical substation etc.

• Three nos. pumping stations with reservoirs, chemical houses and pump houses are

located at different places of Haldia Water Supply project. Another pumping station is

being constructed at Brajalalchak which is expected to be operational by July, 2016.

• Other associated infrastructure like electrical substations, water intake facility and settled

water pump house etc.

• Laying of pipeline from Chaitanyapur to Brajalalchak (Phase-II) has been constructed.

Construction of reservoir at Brajalalchak (Phase-II) and laying of distribution network

from Brajalalchak to Hatiberia (Phase-III) have been started and is expected to be added

with the Haldia Water Supply Project by July, 2016.

The raw water drawn from the river at Geonkhali is treated at the Water

Treatment Plants after which it is pumped to boosting station at Chaitanyapur. Then the

water is pumped at Chaitanyapur to Basudevpur from where the water is distributed to

different industries and domestic consumers. The water from series tube wells are mixed

with treated water at different pumping station to regulate the salt content of the water in

addition to other chemical treatments. Some dedicated water pipelines have been built

which supply water directly to different consumers. Regular operation and maintenance

is vital for ensuring proper water supply.

4.1 OLD 25 MGD WTP & WATER SUPPLY SYSTEM IN HALDIA

4.1.1 WATER INTAKE AND TREATMENT

The supply of water for the entire Haldia is sourced from the Hooghly River at

Geonkhali. Haldia Development Authority (H.D.A.) has an Old 25 MGD water treatment

plant at Geonkhali to cater to the demand of industries as well as domestic water in its

designated command area. Geonkhali is situated on the western bank of the river

Hooghly at the confluence of river Rupnarayan and river Hooghly. Raw Water from the

Hooghly river is collected through a 1000 mm suction mains (4 units) laid inside the river

bed with the help of intake -jetty. This is conveyed to pre-settling tanks of 200 Million

Gallons capacity by 3 nos. of intake channels. Water from pre-settling tanks is passed

through Filter Beds via Clariflocculators and Flash Mixer and finally through filter media.

It is then stored in Underground Clear Water Reservoirs

SCHEMATIC DIAGRAM OF WATER TREATMENT PROCESS AT NEW 25 MGD

WATER TREATMENT PLANT AT GEONKHALI


22

4.2.2 NEW 25 MGD WATER TREATMENT PLANT PROCESS DESCRIPTIONS:

4.2.2.1 PRE-CHLORINATION:

Pre- Chlorination is the application of chlorine to water prior to any treatment process.

The point of application, dosages will be determined by the objectives viz. control of

biological growths in raw water conduits, promotion of improved coagulation,

prevention of mud ball and slime formation in filter beds, reduction of algal growth

in sedimentation tank and filter beds, reduction in colour, odour, taste. It also

minimizes the post chlorine dosages when dealt with heavily polluted water. In this

treatment plant Pre- Chlorination dosing is done at the inlet point of flush mixer.

4.2.2.2 COAGULATION AND FLOCCULATION:

Coagulation refers to destabilization produced by compression of electrical double layer

of the surrounding colloidal particles, while flocculation refers to destabilization by the

adsorption of the large organic polymers and subsequent formation of particle-polymer-

particle bridges. This distinction can have practical significance, since colloidal

aggregation involving destabilization by double layer compression occurs at constant

concentration of coagulant, regardless of the concentration of colloidal material. In

contrast, colloidal aggregation involving destabilization by the adsorption of large

polymers can involve a linear (stoichiometric) dependence of optimum coagulant dose on

the concentration of colloidal material.

The coagulation and flocculation process are accompanied with rapid mixing with

coagulant and subsequent slow mixing for flocculation. Slow and rapid mixing can be

done by mechanical means or by hydraulic means. Here slow mixing and rapid mixing

are done by hydraulic means. A series of baffle wall has been constructed in order to

achieve hydraulic mixing in the coagulation and flocculation chamber with closer spacing

in coagulation zone.

The coagulation and flocculation tank is specifically designed for water treatment mixing

application. It is to ensure complete dispersion of coagulants in the water by passing the

water through a series of baffle walls in the tank with a retention time of 30 minutes.


23

Upon mixing of coagulant to water, a complete physic-chemical reaction occur leading to

the formation of stable floc which will be settled at subsequent sedimentation unit.

4.2.2.3 INCLINED PLATE SETTLER:

It is basically a rectangular sedimentation tank with a series of inclined plate within the

tank where the settle able flocs are settled at the bottom of plate settler. This unit helps

to reduce the amount of fine suspended and colloidal particles present in raw water.

The working principle of plate settler is described below:

• The liquid which contain floc formation particles are introduced between two

inclined plates. Every particle together with liquid will rise until it touches the

surface of the uppermost plate.

• Once the particle and liquid touches the plate surface liquid will rise to the surface

by sliding along the plate.

• Whereas the floc will fall back and touches the lower plate and will slide down

along the lower plate surface.

• Floc present in the liquid will not collide with floc / particular that is sliding down

along the lower plate.

As a result separation of floc / suspended / colloidal particles present in water takes

place. Finally the supernatant water, rising from bottom, will come out through a launder

from the plate settler and is sent to the Filtration Process. The settled sludge will be

transferred to the sludge treatment unit via timer control. The plates are usually set at an

angle between 45 to 60º above the horizontal to obtain self cleaning of sludge from plates.

Normal spacing between the plates is 50 mm.

4.2.2.4 DISSOLVED AIR FLOTATION AND FILTRATION SYSTEM:

Revo-Plus (RVP) is a unique combination of Dissolved Air Flotation (DAF) clarification

and dual media sand filtration in a self contained water treatment module that achieves

excellent water quality. This unit consists of 23 radial chambers in single RVF which

allows 22 chambers in operation and one unit in back washing mode. Thus continuous

production of filtered water and backwashing can be done simultaneously without any

interruption in segments within one RVP.


24

Raw water enters the flocculation section of RVP. Directional inlet nozzles impart a

circular flow required mixing for optimum floc formation. Through the dissolved air

release mechanism located at the top of the inlet zone of RVP micro bubbles are

introduced which adhere to the floc and cause agglomerated particles to rise to the

surface of the treated water. A portion of the RVP effluent is recycled with pressurized

and semi saturated air. The recycled flow is mixed with unpressurised main stream just

before admission to the flotation tank, with the result that the air comes out of solution

in contact with particulate matter at the entrance of the tank. A spiral scoop then removes

the floated and concentrated accumulation of floc via central pipe. RVP has 23 isolated

cells, hence it is possible to back wash one cell at a time without interfering with

filtered water production from the remaining cells. To accomplish this, a backwash hood

is mounted on a rotating carriage, which is supported and driven by wheels at the top of

the RVP tank. The carriage is programmed to either rotate pass a given cell, or to stop,

lower the backwash hood, and backwash a particular cell. The frequency and the

duration of cell backwash is pre set by control panel, which can be adjusted to suit

process condition. The carriage supports the sludge scoop and the electrical rotary slip

rings which distribute electrical power and control function for the carriage drive

motor and scoop drive motor. A rotary air joint supplies air to raise and lower the

backwash hood. All of these functions are operated by the programmable controller.

4.2.2.5 POST CHLORINATION:

Post Chlorination is the application of chlorine to treated water before it enters into

distribution system to maintain the required amount of free chlorine i.e. ≥ 0.5 ppm. The

objective of post chlorination is to destroy the micro-organisms present in water.

Sufficient chlorine is added to maintain free residual chlorine of ≥ 0.5 ppm as specified in

CPHEEO Manual. Chlorine residual is required to prevent re growth of microorganism /

future contamination in distribution system. Liquid chlorine is used for this purpose.

Chlorinator has been provided for proper dosing of chlorine in to the system. A chlorine

analyzer has been installed to determine the free residual chlorine in the system.

7.0 WATER DEMAND PROJECTION:

In a big water supply project like Haldia Water supply Project, where industrial water

demand predominates over others, future water demands are calculated mainly considering

the following parameters-

1. Industrial water demand( existing and new )

2. Present population and growth pattern (considering rate of water supply for domestic

and municipal demand)

3. Commercial water demand( existing and new )


29

8.0 DETAILS OF EXISTING CONSUMERS OF HALDIA WATER SUPPLY PROJECT:

Haldia Development Authority supplies water to industrial, commercial, municipal and

domestic consumers. Water supply to Haldia Municipality is made from several intake

points to their reservoirs. Domestic supply includes bulk supply to housing complexes or

large residential complexes.

8.1.1 LIST OF EXISTING INDUSTRIAL CONSUMERS:

Haldia being an industrial region, industrial water supply to existing and upcoming

industrial units is of paramount importance to HDA. The major industrial consumers of

Haldia Development Authority are MCCPTA, HPL, IOCL, Tata Power etc. They consume

about 86% of total industrial water consumption of Haldia Water Supply Project. The raw

water is drawn from river Hooghly and is allowed to settle in big settled water ponds. The

settled water is then pumped to the treatment plants. Treatment method followed in the

water treatment plant consists of Coagulation, flocculation, sedimentation, filtration and

disinfection. The treated water is stored in an underground reservoir having capacity of 2300

CUM and pumped through 1100 mm and 700 mm dia pipe to the booster pumping station at

Chaitanyapur. A dedicated booster pumping station with three centrifugal pumps has been

constructed at Chaitanyapur to supply water to HPL through a dedicated 500 mm dia

pipeline. From Chaitanyapur booster pumping station, water is pumped to the Basudevpur

Booster pumping Station. MCCPTA is fed by a dedicated line from Basudevpur Booster

Pumping Station through a separate set of pumps. All other industries are directly fed from

Basudevpur Underground Reservoir (UGR). IOCL , Haldia Refinery receives water through

a dedicated 900 mm dia D.I pipeline from Chaitanyapur. From Basudevpur, MCCPTA is

served using five vertical pumps of which two were installed in 1988 and another set of three

installed during 2009. The rest of the industries are served from Basudevpur pumping station

using ‘Primary Grid’ supply network. ‘Primary Grid’ is connected to six pumps located at

Basudevpur pumping station drawing water from the existing 22.7 ML (million litres)

reservoir.

10.0 RAW WATER QUALITY:

The present water supply system primarily uses raw water of river Hooghly drawn through

Intake jetties near Geonkhali Water Treatment Plant.

Raw water collected through intake jetty at Geonkhali has two key quality issues: high turbidity

and high salinity. Out of that, the turbidity issue can be addressed relatively easily through

primary sedimentation and clariflocculation system in the WTPs.

The water to be handled may vary both in quality and quantity. The water quality of river

Hooghly varies from season to season. The turbidity level in rainy season is as high as 1600 NTU

to as low as below 100 NTU in winter. The degree of treatment required may vary seasonally,

monthly and even hourly. Raw water quality of river Hooghly, in terms of turbidity, pH and

Total Alkalinity is given below.

10.1 Salinity in Hooghly near Geonkhali

Geonkhali, the location of the WTPs is in a stretch of Hooghly which experiences a semi-diurnal

tidal cycle. Mixing of saline sea water of the Bay of Bengal with the freshet of Hooghly makes it a

source which is not always a fresh water source. The level of salinity is highest during the dry

period of no or insignificant freshet through Hooghly. Salinity decreases with increase in freshet

during Monsoon and Post Monsoon seasons. Again, level of salinity varies during the semi-

diurnal tidal flows, two high tides in a day giving rise to high levels of salinity while salinity

levels are significantly low during two low tides, in general. The following Table describes

quality of raw water generally available and corresponding duration in a day during different

seasons in a year:

Data were collected three to six times a day, as required for establishment of a daily trend in salinity. During March and June, samples are generally within the WHO guidelines (cause for Rejection) of

potable water that is less than 1000 ppm during low tides. Strict monitoring, however, is required

during April to draw water during the low tides, only for the periods when chloride levels are

within 500-700 ppm levels. Salinity issue is being addressed by HDA by strict monitoring of


44

salinity levels during low tides, prudent operation of pumps and mixing treated water with

ground water from the existing bore wells near Chaitanyapur Pumping Stations.

10.2 Raw Water Pumping Capacity

The Present System has 4 raw water pumps (@ 4500 cum / hour capacity) of the old plant and 4

raw water pumps (@ 5100 cum / hour capacity) for the new plant. Though there are separate

raw water pump houses, raw water reservoir is common. Therefore, raw water pumps could be

run in tandem to supply raw water to both the plants from a common reserve.

Considering no overloading for the pumps, the existing capacity of raw water pumping comes to

28800 cum per hour (3X4500+3X5100). For 7 hours’ pumping, total raw water drawn is about

201600 cum i,e 44.4 MGD. (Loss in treatment, transmission could be met by minor overloading of

raw water pumps for supply of water upto 51 MGD). The suction pipes having 1000mm

diameter, shall be subject to a suction velocity which is well within the permissible limit of

velocity in suction pipes in accordance with the Manual.
