Sturman 430 East Long Lake Road Wayzata, MN 55391 Dear Project Area Residents: The East Long Lake area was included in the recently completed Metropolitan Urban Service Area (MUSA)expansions. This MUSA expansion area included ten existing neighborhoods with smaller lot sizes in which the continued use of septic systems could be problematic. Sanitary sewer has already been installed in seven of these neighborhoods with two additional projects planned for next summer. We would like to begin the process for a possible sanitary sewer project to serve the East Long Lake neighborhood. This would be an assessment project with the benefitting property owners being assessed the project costs. A preliminary cost estimate has been completed for this project. The study lists two possible options for the provision of sanitary sewer. One option is for gravity sewer with a City owned lift station. This is the more expensive option because of the need for deeper 8" gravity lines and the need for complete reconstruction of the street. The estimated cost for the gravity sewer option is$31,000 per unit for ten residential units and one unit for the city park. A service stub would be provided out to the property line and the property owners are then responsible for their own connection to the stub at the property line. The other option is for a pressure sewer system in which a small diameter forcemain would be installed in the street. The properiy owners are then responsible for the purchase, installation, operation,and maintenance of their own residential grinder pump station to pump into the forcemain. A City owned lift station is not required for this option. This option is less expensive because a smaller diameter forcemain can be installed at a shallower depth and complete street reconstruction is not required. The estimated cost for this option is $13,700 per unit. Telephone(612)249-4600 • Fax(612)249-4616
