JICA Project

Pollution Abatement of River Mula – Mutha in Pune

Introduction

The MulaMutha river is one of the 302 polluted river stretches of the country identified by the Central Pollution Control Board (CPCB).

The major reasons for pollution of MulaMutha are discharge of untreated domestic waste water into the river due to inadequate sewerage system (including pumping stations) & sewage treatment capacity in the town, as well as open defecation on the river banks.

A loan agreement was signed on13th Jan 2016 with Japan International Cooperation Agency (JICA) for pollution abatement of river MulaMutha in Pune by January, 2022. Under the agreement, the government of Japan committed to provide a soft loan of 19.064 billion Yen (about Rs. 1000 crore) to India for the project at an interest rate of 0.30% per annum.

The major components proposed under the project include construction of 11 new Sewage Treatment Plants (STPs), which will result in a creation of an additional treatment capacity of 396 million litre per day (MLD) over the existing treatment capacity of 477 MLD, laying of 113.6 kms of sewer lines and renovation/rehabilitation of 4 existing intermediate pumping stations.

Once the project is completed by January 2022, the total STP capacity available in Pune will be 873 MLD, which will be sufficient to cater to sewage generation for the year 2027.

The project also includes installation of a system for centralized monitoring of functioning of STPs, construction of 24 units of community toilet facilities in slum and fringe areas, public participation and awareness programme, GIS mapping of sewerage facilities for better asset management.

Project Proposal

  • Augmentation of Existing Sewage Treatment Capacity by adding new 11 Sewage Treatment Plants (STPs) to cover sewage generation upto year 2027.
  • New STPs to be designed for better effluent quality with 10 mg/L BOD & 10 mg/L TSS along with nitrogen and phosphorus removal.
  • Augmentation of exiting 4 Intermediate pumping stations.
  • For collection of untapped sewage – laying of 113.6 Kms of sewers with house connection & laterals.
  • Installation of centralized SCADA for STPs and IPS to monitor flow and effluent water quality.
  • Implementation of GIS/MIS system for management of assets created under the project.
  • Construction of 24 Community Toilets in slum areas to check open defecation along the river banks.
  • Institution development and Capacity Building.
  • Facilitation of Public Awareness Programs.

MAIN OBJECTIVE

  • To improve water quality and river ecology as well as stoppage of pollution of river Mula -Mutha.
  • To intercept, divert and treat the domestic sewage generated discharging in the river.
  • To tackle the non-point sources of pollution to improve the hygienic condition of city and surrounding areas and aesthetics of river front.
  • Institutional strengthening and capacity building & Public Awareness for sustainability of Projects.

MAIN FEATURES

  • Total prevention of domestic sewage being discharged into river from Pune City.
  • STPs with Decentralized approach.
  • Provision of STPs to mitigate biological and bacterial pollution.
  • Treated sewage to be used for agriculture – about 515 MLD pumped into agricultural canal (agreement with irrigation Dept.)
  • Rehabilitation of existing 50 years old trunk sewer and existing STPs /IPS.
  • Integration with the existing facilities.
  • To provide measures for sustainable operation & maintenance of the assets thus created.

Funding Pattern

  • Govt. of India  – 85% –  Rs 841.72 Crore
  • Pune Municipal Corporation – 15% – Rs. 148.54 Crore

            Total Rs.  990.26 Crore

The loan negotiations for the project were held on 26th February, 2015 in DEA & based on the loan negotiations ‘Exchange of Notes’ for providing the loan amounting to 19064 million Japanese Yen at the interest rate of 0.3% per annum for the project has been concluded between Government of Japan and Government of India on 27th March, 2015.

INSTITUTIONAL DEVELOPMENT PROGRAMME

  • Training for enhancement of technical capabilities of existing manpower to reduce the senior management in day to day operation.
  • Strengthening of existing computerized system for accounting and e-Governance.
  • Technical, Financial and Management Training Program for Project Implementation Unit (PIU).
  • GIS based sewerage system mapping for proper operation & maintenance and monitoring of the sewerage systems.
  • Application of GIS based asset management system with property details including details about owners, their ARV details, details of water and sewage connections and PMC taxes.

Public Participation and Awareness

  • For sound operation and maintenance of sanitation facilities, and ensure its sustainability, public participation and public awareness programme has been proposed involving the NGOs and CBOs (Community Based Organizations).
  • Participation of Schools for pollution Awareness programs.
  • Radio programs and advertisements through CSR for creating awareness for abatement of pollution of Mula-Mutha.

Outcome of the Proposed Works

  • Domestic Wastewater discharging directly or indirectly into the river will be intercepted and target of total prevention of sewage discharge into the river will be achieved.
  • Provide relief to existing 90 years old trunk sewer
  • Treated sewage will be used for irrigation in agriculture
  • Effluent of proposed STPs will be utilized for irrigation of nearly 21,000 Hectares by pumping 515 MLD of treated water into Canal network of irrigation Department.  Irrigation has given discount on raw water usages to PMC

Provide Up- gradation and rehabilitation of existing sewerage facilities in the city.
