Description:

This project provides regional interceptors to convey wastewater from Lake Elmo. This project was originally included as part of the South Washington County Interceptor project. It includes two new connections to Lake Elmo. The Lake Elmo East Connection will provide 1.7 MGD of average daily capacity to eastern Lake Elmo. A gravity interceptor sewer would start at I-94 and proceed about 0.4 miles south along Cottage Grove Drive to a new regional lift station to be built in Woodbury. From the planned initiation of operation in 2007 until 2010 this flow will be temporarily routed through Woodbury trunk sewers. After 2010 the flow will be permanently diverted into the planned Northeast Leg of the South Washington County Interceptor. In both cases the flow will be conveyed to the Eagles Point Plant in Cottage Grove via the portion of South Washington County Interceptor along County Road 19 south of Lake Road, which was completed in 2005.

The first phase of a second, new connection for Lake Elmo, entitled Lake Elmo Forcemain to WONE, was constructed in 2005 under the Small Systemwide Improvements Program (SSIP). The remainder of the project is being constructed under this project. This new connection will provide 0.5 MGD of average daily capacity to southwestern Lake Elmo. The existing 3,600 feet of 12-inch forcemain along Radio Drive will be extended to Lake Elmo by construction of about 3,500 feet of new 12-inch forcemain terminating at the existing Lake Elmo lift station located east of Inwood Avenue. Also, 4,600 feet of the existing 16-inch Woodbury Wilmes Lake Forcemain to the WONE Interceptor need to be acquired from Woodbury, inspected and rehabilitated as necessary. Operation of this system is scheduled to begin in early 2008. This wastewater would flow to the Metropolitan Treatment Plant via the MCES' WONE (1-WO-500) Interceptor.
