CHAPTER 6OPERATION AND MAINTENANCEOF SEWERAGE SCHEMES6.1 CRITICALITY OF O&MOperation and maintenance of assets has emerged as a major concern in the success of thisprogramme. NRCD has decided that funds for O&M for a period of 5 years initially, would beshared in the ratio of 70:30 between the centre and the State Government. Next 10 yearsO&Mcost should also be worked out with revenue generation plan. TheO&Mresponsibility beyond5th year will rest with the State Government/ ULB.Tripartite MoA amongst MoEF, State Government and the local body is also to be signed. Stategovernments are expected to take all necessary measures available at their control to addressthis problem in a sustainable manner.It is necessary to accurately work out O&M cost. The records of O&M of assets created underGAP/NRCP may be examined carefully and updated to the current levels as well as the periodswhen new facilities would be ready for operation. Cost of electricity is the major component ofO&M accounting singly for 65-70%. These as well as other components like manpower,consumables, etc. should be calculated on a realistic basis to arrive at the total annual cost tooperate an asset. Continuous availability of electricity for both STPs and PSs must be ensured onround the clock basis by the implementing agency.Preventive maintenance or repairs needed after a few year's initial operations are often lostsight of. This is an important element of overall O&M cost and must be provided forappropriately.The DPR must clearly reflect the total component-wise funds needed for O&M and how andwherefrom these would be provided.If the O&M is done departmentally, there will be requirement of staff.

The contractor mustbe asked to offer performance guarantees through proper O&M to achieve the outcomes.As part of capacity building programme, operation and maintenance manuals have to be madeavailable to the ULB's staff by the DBO contractor.6.2 RESOURCE RECOVERY AND REVENUE GENERATIONWith little additional and dedicated efforts, sewage treatment could be converted into a52
