A general description is given of the cause and development of the facilities intercepting dry flow sewage provided in the stormwater pumping station in the area of Shanghai, with detailed design ideas thereof in the south area of Beixinjing, which has well solved the problem of land occupation of the station, with lower construction cost and higher social and economic benefits.

Four methods with different Intercepting Facilities are proposed and the influence of these methods on city inland rivers and sewage system is analyzed.

Yangzhou City sewage interception project is responsible for sewage and part of rainwater collection and transmission in the old town, the southeast, and the northeast parts of the city.

The design of the sewage interception and the!key points during construction were detailed including determination of the overall plan,design of the intercepting well and sewer,choice of pipe,foundation treatment,revetment repair and reinforcement and so on.

Aiming at the three sewage interception facilities(Da Wuchuan,Changqiao and Meilong) of Suzhou River water system sewage interception and treatment project,the detailed design plan and construction were put forward by the author.

Comparison and optimum design of various sewage intercepting wells;

Discuss on comparison and optimization for different types of sewage intercepting wells;
