New sewer system after earthquake

Sun Moon Lake, the largest fresh water body in Taiwan, is located in the middle of the island at an elevation of 750 m ASL. The local infrastructure was badly damaged by the 921 Chi-chi earthquake in September 1999. MAA was engaged to provide the detailed design of a new sewer system for the lakeside villages, Sueishe and Riyue.

 

A challenging terrain

Big elevation differences, hard rock composition and the high number of visitors in this tourism hotspot required careful technical design and construction. 7,700 residents are served by the sewer system. The sewer has a 7.7 km long gravity system, a 1.6 km long pressure pipe and a pumping station. The project comprised the design of two wastewater treatment plants including mechanical, chemical and biological treatment methods. The work scope consisted in the design of complete treatment units, including civil, architectural engineering works and landscape works. The treatment technology will adjust to the heavily fluctuating influent quantity and the strict limit values of the outflow.

 

Scope of work

  • Design of complete sewerage
  • Design of two wastewater treatment plants, with a design capacity of 1,100 and 1,000 CMD
