View of water supply system

Overview

Guwahati is the largest city in Assam and in the northeastern region of India; its population in 2007 was approximately 1.11 million, which is estimated to increase to 2.80 million in 2025, and to 3.23 million in 2040. Guwahati City is divided into four distribution zones for water supply -- south central, southwest, southeast and north. With the rapid growth of the urban population and economy, the gap between water demand and water supply has been widening. The public water supply pipeline currently reaches approximately 30% of the city, mostly in the south central zone, and within this area, individual households only have running water for two to three hours each day because of the degraded water treatment plants and the high leakage rate. Citizens without access to water supply rely on groundwater, which is not safe for drinking. However, the city sits along the banks of a large water source, the Brahmaputra River.

The Government of Japan extended a package of Official Development Assistance to India to construct water supply facilities in the southcentral and north zones of Guwahati city. The new infrastructure, funded by the Japan International Cooperation Agency, will provide continuous, pressurized and potable water supply to all people living in the area, significantly improving current living standards. The Louis Berger Group is providing project management consulting services to the Guwahati Metropolitan Development Authority throughout the project’s lifecycle. As the project manager, LBG is preparing detailed design and drawings of water supply facilities, reviewing and finalizing detailed cost estimates, establishing a procurement management system and tender process, supervising and managing its contracts, liaising with JICA and other authorities, and providing financial management. LBG is also working with the GMDA to strengthen its project implementation unit, conducting environmental monitoring, and monitoring and evaluation of the project. As part of design process, LBG is conducting topographical survey, geotechnical investigations, raw water-quality analysis, hydrological studies and hydraulic modeling, and GIS-based mapping. Our team is assisting the GMDA to establish a thorough operation and maintenance (O&M) system. We studied and recommended the appropriate institutional arrangement, and will assist the GMDA to develop systems, protocols and manuals for efficient O&M. LBG will provide necessary in-country and overseas training trainings during the project to all O&M staff and PIU.
