8 MUNICIPAL CORPORATION OF GREATER MUMBAI Solid Waste Management 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

9 MUNICIPAL CORPORATION OF GREATER MUMBAI Solid Waste Management 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 source 2. Reuse : Involves the repeated use of items or parts of items which still have usable aspect 3. 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

10 MUNICIPAL CORPORATION OF GREATER MUMBAI Solid Waste Management MCGM Initiatives… Kanjur (66 ha): – Bioreactor (42 ha): 3000 tpd scalable upto 6500 tpd with no extra capital works–Perpetual – Composting (8 ha): 1000 tpd – Landfill (7 ha): for 25 yrs, 250 tpd Process rejects & remnants Deonar (55 ha): – Composting (16 ha) : 2000 tpd – Landfill (14 ha): for 25 yrs, 500 tpd Process rejects & remnants Mulund (4ha) : – Biomethanisation : 500 tpd (hotel & market waste) No landfill Summary – Out of total 7000 tpd MSW generation : 950 tpd recoverable through MRF (Material recovery Facility) – 6,500 tpd Processing facility scalable upto 10,000 tpd at short notice – Facility created can meet Mumbai need till total MSW Generation reach 10,000 tpd

13 SEWERAGE AND SLUM SANITATION Municipal Corporation of Greater Mumbai

14 14 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)

15 LIQUID WASTE MANAGEMENT -Seven Sewerage Zones of Mumbai

16 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 b)390Mld Sewage at Malad will be treated with suitable biological treatment and 4km long Marine Outfall, taking into consideration projected flow by c) The Treatment as well as Pumping capacity will be upgraded suitably to meet the requirement for the flow by 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

17 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

18 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.

19 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.

20 SLUM SANITATION 1) Slum population covered by 4.44 million Community Toilet blocks 2) Slum population covered 0.19 million (38,553 X 5) by individual toilets- 3) Population served by 7.38 million ( This includes 2above) Household toilets (Formal Housing) * 52.52%of present population lives in slums on 10%of land area of Mumbai

21 Goal - Slum Sanitation Programme… To improve health & hygiene of slum dwellers To provide sustainable sanitation facilities, mainly for safe excreta disposal To involve prospective beneficiaries in process from selection of site to construction, O. & M. activities To evolve ownership concept amongst the beneficiaries

22 Salient Features of S.S.P. Toilets Demand driven scheme User community to form C.B.O. User community to pay upfront contribution of Rs. 100 per adult, max. Rs. 500 per family Construction of toilet block – R.C.C. To provide separate seats for gents and ladies To provide Bath room for gents and ladies

23 Cont’d To provide urinal for gents To provide caretaker room on top of Toilet Block Provision of 24 Hrs Water & Electric supply Caretaker to stay in the top room round the clock To issue family passes to user community C.B.O. to bear water, electricity charges & payment of caretaker & daily maintenance

24 Program of construction of Community Toilets YEAR Cumulative May 2001 Cumulative May2012 No of Toilet blocks No of seats Work in Progress

25 Pay and Use Toilet Blocks Pay and Use toilets constructed mainly for floating population Constructed on BOO basis Users charges as per MCGM norms, generally Rs. 2 per use Urinal facilities provided free of cost Pay & Use toilets constructed mainly by NGOs Water, electricity and other charges including repairs and maintenance born by the operators

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

27 ….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.

28 ….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.

29 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

30 IMPORTANCE Protection to shoreline from seawaves, Cyclones Nursery for marine fauna Living for fisherfolks Construction & timber Carbon Sinks Ecological balance Research Education

31 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.
