Conventional Waste Management Challenges

• Limited efforts on reducing waste at source

• Lack of segregation, poor collection, illegal dumping, open dumping and burning of waste

• Limited involvement of private sector and communities

• Considers waste having no value

• Relies on Landfills & Composting

• High cost of land in Mumbai city

• Green House Gas (Methane) generation

Sustainable Waste Management-Solutions Reduce, Reuse and Recycle (the 3Rs) offer an

environmentally friendly alternatives to deal with growing generation of wastes and its related impact on human health, economy and natural ecosystem

1. Reduce: Choosing to use items with care to reduce the amount of waste generated at source2. Reuse : Involves the repeated use of items or parts of items which still have usable aspect3. Recycle: Use of waste itself as resources Resource recovery through waste processing

• -- Biological Processes -- Thermal Processes

Landfill Disposal: Dispose of items which cannot be used by any means

Mumbai Sewage Scenario-Experiences

Current Population : 12.4 Million (census 2011)

Slum Population : 6.5Million (census 2011)

Water Supply : 3350 Mld

Sewage generated : 2600 Mld

Area under Sewerage network : 62%

Sewage collected : 1700 Mld (65%)

Sewage Treated : 1) By way of Aerated lagoon: 430 Mld, meeting Effluent Discharge standards (Versova, Bhandup ,Ghatkopar)

2) Through Marine Out Falls : 880 Mld ,meeting SWII Standards except coliform, no Biological Treatment.

(Colaba, Worli, Bandra) 3) With Preliminary Treatment Only :390Mld ,not meeting effluent discharge standards (Malad)

LIQUID WASTE MANAGEMENT -Seven Sewerage Zones of Mumbai

Treatment

Challenges

Action Plan

I) Non compliance of MPCB consent standard

a) 880 Mld Sewage , plant at Colaba Worli and Bandra, will be treated with suitable biological treatment taking into consideration projected flow by 2031.

b)390Mld Sewage at Malad will be treated with suitable biological treatment and 4km long Marine Outfall, taking into consideration projected flow by 2031.

c) The Treatment as well as Pumping capacity will be upgraded suitably to meet the requirement for the flow by 2031.

IV) Availability of adequate land for treatment facility.

1.New technology with smaller foot print.

2.Treatment with Stack arrangement.

3. Land required for Worli will be acquired by removing the encroachment by way of SRA.

4)Land required for Bandra will be acquired from MSRDC

Challenges

Action Plan

I) Coverage in slums

1)Expansion of Sewerage networks

2)Due to paucity of place sewer lines cannot be laid in slum areas and problem will persist. For this Sewage from slums , will be collected by diversion of flow from Storm water drains to Sewer line in Dry season.

II) Unsewered Area

Phase-wise expansion of sewerage networks

Coverage

Action Plan – In Progress

1) Expanding existing network by conventional Open cut method and Micro tunneling.

2) Replacing 5nos of existing satellite pumping stations. 3) Construction of new Influent and Effluent pumping

stations at Two places in Mumbai ‘s Western suburbs Malad and Versova.

4) Conditional assessment and rehabilitation of 25Kms of Man –entry Sewers.

5) Construction of about 13Kms long Collector Tunnel in Western suburb .

6) Construction of 5km long two transfer tunnel in Western suburb.

Cont’d

7) Construction of 3.9M dia x6.0Km long Marine outfall in Western suburb.

8) Improving level of Sewage Treatment at all 7 locations ,so as to achieve 20mg/litre BOD and 30mg/litre SS in creek/Harbour and 100mg/litreBOD and SS in West coast.

* The Consultants for the works at s.no 2 to 8 are in place and their BODR are ready for invitation of bids ,so as to complete these works by end of 2017.

SLUM SANITATION

Mangroves Protection : Introduction

• Ministry of Environment & Forest, Govt. of India vide notification S.O.19(E) dated 6th January 2011 published the new Coastal Regulation Zone (CRZ) Notification 2011.

• The CRZ notification regulates the development so as to protect the natural coastal barriers like reefs, dunes, mangroves, beaches and terrestrial vegetation.The CRZ are classified into 4 categories (i.e CRZ-I, CRZ-II, CRZ-III & CRZ-IV).

….contd.• CRZ - I covers ecological sensitive areas

like Mangroves, mudflats, sand dunes etc…..

• Mangroves are one of the important geomorphological landforms in coastal ecosystem.

• As per the CRZ Notification in case of Mangroves area more than 1000 sqm. a buffer of 50 m along the Mangroves is to be maintained.

….contd.• All mangrove areas are to be mapped and

notified as protected forest and necessary protection and conservation measures for the identified mangrove area is to be initiated.

• Five times the number of mangroves destroyed/cut during the construction process shall be replanted.

• It is in form of trees and shrubs of varies species with several families, mostly found with seawater and around tidal influenced bodies, likes creeks, estuaries, wetland etc.

Mangroves: Silent Coastal Saviors

•Halophytic plants that grow at interface between soil and water

•Evolved around 114 million years back

•Mangue- Into the sea Groves- Garden/Forest

IMPORTANCE• Protection to shoreline

from seawaves, Cyclones

• Nursery for marine fauna

• Living for fisherfolks• Construction & timber• Carbon Sinks• Ecological balance• Research• Education

Conservation of Mangroves• Hon’ble high Court of judicature of Mumbai has

directed the State Coastal Zone Management Authority to carry out the satellite mapping of mangroves of the state of Maharashtra for their protection and conservation.

• Accordingly Maharashtra Pollution Control Board, Mumbai has entrusted the studies “Satellite mapping of mangroves of Maharashtra” using two data IRSP6, AWiSF data under phase-I to Maharashtra Remote Sensing Application (MRSAC)Center, Nagpur.

• All the mangroves area have been declared as Protected Forest by State Government of Maharashtra.

Our Role In Mangrove Conservation

• Understand mangroves

• Conduct & encourage research

• Prevention of tree cutting

• Watch on neighbourhood areas

• Follow up ‘3R Principle’

• Participation in conservation
