Investment support will be provided to modernize and expand urban water supply and sanitation – while strengthening relevant institutions to enhance efficiencym productivity and sustainability in water use. Mangalore sewerage subproject is one of the subprojects proposed in Tranche 2. Previously, Karnataka Urban Infrastructure Development and Finance Corporation (KUIDFC) implemented the ADB assisted Karnataka Urban Development and Coastal Environment Management Project (KUDCEMP), which initiated water supply and sewerage improvements in 10 coastal towns. However, owing to shortage of funds, the subprojects were not comprehensive enough to have full coverage and was limited to critical major works only. Hence, under the KIUWMIP, it is proposed to support four coastal towns (Kundapura, Mangalore, Puttur, and Udupi) to implement 24x7 water supply systems, besides sewerage improvements where required. Mangalore City spreads around an area of 132.45 square kilometer (km2) and is located at 12°87’N latitude and 74°88’E longitude. The topography of the city is from plain to undulating with four hilly regions with natural valleys within the city. The city is characterized by undulating topography.Mangalore is situated on the west coast of India, and is bounded by the Arabian Sea to its west and the Western Ghats to its east. Mangalore is the largest urban center of coastal Karnataka and the fourth largest city in Karnataka in terms of area and population. Mangalore is located about 350 kilometers (km) west of the state capital, Bangalore. Categorization. ADB requires the consideration of environmental issues in all aspects of the Bank’s operations, and the requirements for environmental assessment are described in its Safeguard Policy Statement (SPS), 2009. The proposed projects are categorized as A, B, C or FI to determine the level of environmental assessment required. Mangalore sewerage subproject is classified as Environmental Category B as per ADB SPS, 2009 as no significant impacts are envisioned. Accordingly, this initial environmental examination (IEE) report has been prepared. Subproject Scope. Under this subproject, it is proposed to replace existing sewage pumping mains, which are damaged, undersized and/or chocked up in sewerage zones 3, 4, 6 and 7. Subproject included providing following sewage mains: (i) 7.65 km length 1,100 millimeter (mm) diameter sewer pumping main from Kudroli wet well no.3 to Kavoor sewage treatment plant (STP); (ii) 0.95 km length 900 mm diameter main from Kandathpalli wet well no.-4 to Kudroli wet well no. 3; (iii) 1.7 km length 450 mm diameter main from Mulihitilu wet well no.-6 to Ridge Manhole near Morgans gate; and (iv) 1.1 km length 450 mm diameter main from Jeppu Bappal wet well no. 7 to ridge manhole near Yekkur, inside old STP. Implementation Arrangements. KUIDFC is the executing agency responsible for overall technical supervision and execution of all subprojects funded under the Investment Program. Implementation activities are overseen by program management unit (PMU) established in its head office at Bangalore in coordination with its regional office (RPMU) in Mangalore. PMU and RPMU are staffed with technical, administrative and financial officials, including safeguards specialists, to manage and monitor program implementation. The implementing agencies are the respective urban local bodies (ULBs). For this package, the implementing agency is Mangalore City Corporation (MCC). A program implementation unit (PIU) has been set up for implementation of day-to-day activities in the field. A consultant team, project management, design and ii construction supervision consultant (PMDCSC), assists PMU, RPMU and all PIUs in subproject planning and management, assures technical quality of design and construction, designs the infrastructure, and supervises construction including conducting all safeguards tasks. Description of the Environment. Subproject components are located in Mangalore urban area or in its immediate surroundings. Subproject sites are located in existing right of ways (ROW) of public roads, which are government-owned. There are no protected areas, wetlands, mangroves, or estuaries in or near the subproject location. There are no forest areas within
