IIT Bombay IIT Delhi IIT Guwahati IIT Kanpur IIT Kharagpur IIT Madras IIT Roorkee Model Projects Suggested Approach Way Forward? September 22-23, 2011 by International Workshop PPP Models and Technological Solutions for Sewage and Waste Management & Slide 2 Model Projects September 22-23, 2011 International Workshop PPP Models and Technological Solutions for Sewage and Waste Management 1.Cluster of Pulp and Paper Industries in Uttarakhand and Uttar Pradesh 2.Tannery Effluents and Sewage Treatment in Kanpur, Uttar Pradesh 3.Sewage Treatment in Patna, Bihar 4.Sewage Treatment in Kolkata, West Bengal 5.Distillery Industries in Ganga Basin Slide 3 Ganga Basin Drainage Area of the Ganga River Covering 11 States in India (AIWFS Data) Slide 4 Haryana Rajasthan Madya Pradesh West Bengal Bihar UP Kanpur Yamuna Ganga Ram Ganga Kali Yamuna Gomti Ghagar Gandak Son Ganga Kosi Delhi Banaras Allahabad Uttarkashi Rishikesh Haridwar Garh Mukteshwar Patna Lucknow Mathura Agra Slide 5 State Governm ent Central Governm ent Public ULBs Service Provider / Operator DBFO Model for STPs Slide 6 The service provider/operator builds, and then maintains and operates the facility for the contract period after commissioning. Responsibility for the arrangement of uninterrupted power supply for the facility is with the service provider/operator. The service provider/operator and ULB will have joint rights (as stipulated in the contract) for the commercial exploitation of the products, i.e., treated water, sludge and sludge-derived products generated through sewage treatment. A special purpose vehicle (SPV) may be set up for this purpose by the service provider/operator and ULB using the PPP model. Any treated sewage, sludge, etc. discharged from the sewage treatment facility during the contract period to be disposed of by the service provider/operator in a safe manner and as per provisions of the contract. DBFO Model for Sewage Treatment - Essential Components Slide 7 The facility reverts back to the ULB after the end of the contract period unless the contract duration is extended. Any liabilities arising out of site contamination during the construction period and contract period for operation of the facilities by the service provider/operator lie with the service provider/operator, even after conclusion of the contract period. The facility reverts back to the ULB after the end of the contract period unless the contract duration is extended. Any liabilities arising out of site contamination during the construction period and contract period for operation of the facilities by the service provider/operator lie with the service provider/operator, even after conclusion of the contract period. DBFO Model for Sewage Treatment - Essential Components Slide 8 In this model, the income to the service provider/operator will be from two sources: Payment made to the service provider/operator in the form of annuities. The expected amount of annual payments (for each year of operation after commissioning) will be clearly specified in the contract. However, the actual annual payments shall be linked to the quantity of treated sewage (of specified quality) produced by the service provider/operator in that year. Profit (if any), from commercial exploitation of resources generated through sewage treatment, i.e., sale of treated water, sludge and sludge-derived products, as per provisions specified in the contract. In return, the service provider/operator is expected to invest the entire funds required for initial creation of the sewage pumping and treatment infrastructure as per the approved DPR and also take care of operation and maintenance of the facility through the operation and maintenance contract period. DBFO Model for Sewage Treatment - Essential Components Slide 9 State Pollution Control Board Central Pollution control Board Industry Associati on (Compan y Ltd) Industry Associati on (Compan y Ltd) Industry Service Provider / Operator DBFO Model for Industry Slide 10 Most of the ETPs perform much below the expected level and most of the times effluent discharge norms are violated. Lack of knowledge and expertise to manage the ETPs and lack of resources and man power for enforcing the regulations and taking actions have been cited for poor performance. In several instances causes beyond technical and financial are responsible for unabated pollution of rivers. DBFO Model for Industry Clusters/Groups Slide 11 It is recommended that ETPs are planned on DBFO model with third party involvement as a company floated by the Association of Industries. The ETPs will be in the premises of the industry. Land for the ETP is to be provided by the industry. The company will be responsible for managing the effluent recycling plants through service provider/operator using DBFO model and will receive funds in the beginning of the year from each of the industry towards supply of treated water of industrial grade produced from effluents discharged by the same industry. The service provider/operator will get the payment based on quantity of industrial grade water produced from the effluents on monthly basis. Renewing consent to operate the industry may be linked to deposition of funds in the accounts of the company floated by the Association.
