On this project, a new gravity sanitary sewer collection system was installed to provide the residents with modern dependable sewer service. The saturated soil conditions caused the existing septic systems to have difficulty providing adequate sewer services.
When installing a new collection system in an established subdivision, the existing infrastructure must be considered during the design and construction of the location and depth of the gravity pipes. Establishing strong communication with existing businesses ensured that site access was maintained, disturbed areas were restored to owner’s satisfaction, and that sewer service was not interrupted. Land owners of empty lots were contacted to discuss future developments to ensure proper placement of future sewer connection. Trenchless installation of the sewer pipes was required under the streets and driveways to aid in minimizing future settlement of the pavement.
The project provided service to 60 businesses and 2 residences and consisted of installing 28 sanitary manholes and over 7,600 feet of sewer main.
