The proposed investment project will cover rehabilitation to the existing systems, repairs to the sewer outfalls, upsizing of under capacity sewers, and upsizing of under capacity pumping stations. The project will have special focus on the methodology to include the low-income groups and poor communities in the urban and rural areas. For commercial and institutional areas, the consultants will develop discharge standards for commercial and institutional wastewater connecting into the sewer network. The consultant will also design standard pre-treatment facilities for small-scale industries to meet the proposed discharge standards. For onsite sanitation, the consultants will study and develop environmentally friendly and economical method to treat wastewater from gully emptying tanks, and thereafter develop the bidding documents to evaluate, negotiate and contract for a pilot project. In addition, institutional and capacity building components will be formulated for the purpose of improving asset management, operation and maintenance of the sewerage system, and achieving cost-recovery.
