Project #8038, Chaska West Interceptor

Description:

The project consists of the construction of an interceptor system to convey 5.66 mgd average daily; flow. Service area for the proposed interceptor will be approximately 7,000 acres and includes the cities of Chaska and Carver as well as areas to west along the Hwy. 212 corridor. A gravity interceptor will be extended as far toward Carver as feasible. The remainder of the system will include a lift station at the Carver WWTP site and a dual forcemain to the gravity sewer.

Project Map

Purpose and Justification:

Projected development within the Cities of Chaska and Carver will cause wastewater flow to exceed the present interim lift station capacity by the year 2009. The City of Chaska is planning sewer and street improvements in the area leading up to present lift station L71. The city has sized the trunk sewer to convey flows from Chaska and Chaska Township (to be annexed by the City). The MCES was approached by the City of Chaska on the possibility of entering into an cooperative agreement to allow acquisition of a portion of the trunk sewer when flows from communities south and west of Chaska begin to enter the trunk sewer system. Trunk sewer reconstruction in the area presents an opportunity for the MCES to upsize the proposed trunk sewer to accommodate future projected flows from Carver and other areas to west. The City of Carver has indicated its plans to formally request Rural Growth Center status and extension of the interceptor to phase out its wastewater treatment plant will serve long-term growth of this area.
