IFC is considering a $5.5 million loan to Vishwa to be applied to the Khandwa water supply project and the Kolhapur STP. The Khandwa water supply project, Madhya Pradesh, is a public-private partnership between Khandwa Municipal Corporation (Khandwa MC) and Vishwa, under the Urban Infrastructure Development Scheme for Small and Medium Towns (UIDSSMT). The project will commence supplying 29 million L/day (MLD) to Khandwa (population 240,000) for domestic consumption, increasing to 43 MLD by the end of the concession period (2034), meeting the current shortfall by almost doubling the volume of water currently supplied. Under this build-own-operate-transfer (BOOT) scheme, Vishwa has a 25 year concession period (2 years construction, 23 years operation and maintenance). The project will pump water through an intake well on the Chhotitave River, a backwater of the Indira Sagar Reservoir, to the adjacent water treatment plant (WTP). The WTP (2.7 ha site) will treat water using water clarification / the application of alum for flocculation and chlorination, then pump it to Khandwa via a 50 km long 800 mm reinforced trunk pipeline. The pipeline will discharge into a 1,222 m3 ground level master balancing reservoir (GLMBR), from where it will be pumped to nine separate overhead tanks. Water will then be gravity fed to the township. The project includes the laying of 60 km of poly distribution pipeline through the streets of Khandwa. Project construction commenced in late 2010.The Kolhapur STP and allied works, Maharashtra, is a long-term public-private partnership between Kolhapur Municipal Corporation (Kolhapur MC) and Vishwa. The project, an initiative contributing to the Panchganga Action Plan (PAP), has the objective of preventing and controlling the discharge of sewage entering the Panchganga River via the four main nallahs (streams) that drain Kolhapur. The Ichalkaranji section of the Panchganga River was declared critically polluted by the Central Pollution Control Board (CPCB). The existing city STP (43 MLD treatment capacity) is limited to primary treatment (primary screening, grit removal and settling) and has inadequate capacity. As a result, treated sewage does not meet CPCB standards, and overflows from the existing STP plus partially treated and untreated sewage flow almost directly into the Panchganga River that serves as a potable water source for Kolhapur and other settlements. The project will intercept and pump untreated sewage from nallahs into the new STP. The STP will treat wastewater using: (a) primary treatment - conventional mechanical methods; and (b) secondary treatment - sequential batch reactor (SBR) technology that allows variable flows to be treated by this activated sludge method. A high quality effluent will be produced with low turbidity and low nitrogen levels. The STP will service Kolhapur city (population 493,000 in 2001) with a treatment capacity of 76 MLD, replacing the existing STP. The project consists of: the STP at Kasba Bawda; a sewerage pumping station and rising main at Bagat Camp and Line Bazaar; a rising main at Jayant Nallah; a discharge pipe between the STP and Panchganga River; and miscellaneous civil works. Under this design, finance, construct, operate and maintain scheme, Vishwa has a 15 year concession period (2 years construction, 13 years operation and maintenance). The STP site is located within an existing compound owned by Kolhapur MC, next to the existing STP operated by the Corporation. Project construction commenced in early 2011.
