The total volume of this project is IO thousand cubic meters. The whole project consists of three part which is water diversion project, water transport and allocation project and water treatment project The surface water diversion project consists of the selection of water source location, the forrn of water diversion and the design of pump station. The water clarification project is the major part in this paper. It consists of the choice of the water plant location, processes selectio n, water tTeatment co nstructions design, plant layout and architectural design. This paper also demonstrates the detail of process of design for each constn1ction or apparatus in the water treatment plant. It is divided into t\vo parts water treatment plant designing and water proportioning plant designing. According to the surveying about quality of raw water, the raw water can be transmitted to the user only through simple disinfection (add chlorine) Two sets of program have been compared both technologically and economically. And the first program is preferred. Tl1e whole process is as follows: raw water.... pipe-shaped mixing apparatus ....mechanical stirring clarifier .... water treatment project-+ flocculent tank.... non-valve filter ....clear wen.... high-service pumping station.... municipal pipe network. KeYo r d s: water diversion projects; water transport and allocation projects; water treallnent project;flocculent tank;slanting canal
