Therefore, the reasonable water drainage works for the planning, design, construction and operation of management, guarantee the security of its system to normal operation of the economy to meet the needs of life and production, and this is certainly very important.Outdoor urban water supply and drainage project is the construction of an important ponent of its main tasks is to provide adequate number of towns and meet certain water quality standards。ForewordWater drains, water supply and drainage project is an important ponent of the project can be divided into drains and water supply pipeline project works two categories.Water pipeline project is on the upgrading of water, transmission, storage, distribution and regulation of science. Its most basic task is to ensure that the raw water source sent to the water treatment structures and water users with the water quality standard transmission and distribution to users. This task through the pump stations, pipelines, distribution mains network structure and regulation and other facilities to work together to achieve, and they formed a water pipeline project. Design and management is a basic requirement for at least the construction costs and management fees to ensure that the necessary water users and pressure to ensure water quality and safety, reduce leakage and achieve the required reliability.Water drainage network project is a water supply and drainage project in the very important ponent of the needs (building) there is also a great investment, the general water supply and drainage works about a total investment of 50% to 80%.
