The system serves 205 residential connections. It is designed to accommodate 46,000 GPD peak design flow. The collection system consists of 17 interceptor tanks, four effluent lift stations (duplex) and one central effluent collection sump (triplex). The dual disposal system is comprised of a summer disposal field with six zones and a winter disposal field with three zones. There are 5,900 lineal feet (1.2 miles) of leachline and 22,500 lineal feet (4.3 miles) of trench for collector sewer.
One primary design objective was to flood proof the system to prevent inflow and silt intrusion. Electrical controls were installed above flood elevation with backup power supply for reliability. A hybrid STEP / STEG collection system was used to remove solids and convey effluent wherever possible. The design strategy was to use as few pumps as possible, while maintaining reliability. A central effluent collection sump is used for pumping to disposal field. Use of a telemetry control panel at the central sump aids monitoring and trouble shooting.
