1. Background and Objectives

• The Cambodian government has been developing water supply facilities in provincial cities with the goal of securing access to safe water for the entire population of urban areas by 2025. Since 2007, the Japanese government has been providing major provincial cities with technical cooperation and other assistance for water supply improvement.
• Svay Rieng City lacks the capacity to supply water for its population, and the coverage ratio of water supply in the urban area was still 48.9% (as of 2019). Residents who cannot access water supply obtain water from a home-use well and rainwater, and the expansion of water supply facilities is an urgent issue for improvement of the public health environment such as water quality and better convenience.
• With this project, which is to construct a water intake facility, conveyance pipes, a water treatment plant,and a water transmission and distribution piping network in Svay Rieng City, the coverage ratio of water supply in the urban area of Svay Rieng City is expected to improve to about 86.7%.
