Pump Stations The District has two primary sewage pump stations and one small backyard pump station serving three residences within the collection system. The Lake Gregory Pump Station is located on the east side of Lake Gregory along San Moritz Way and receives raw sewage from Assessment Districts 2, 11, 12 and the Pinecrest area. The pump station was built in 1968 with construction of the sewer system for AD No. 2 and also serves Assessment Districts Nos. 11 and 12, and was expanded in 1988 to accommodate flows from Camp Pinecrest. Both units are automated, vertical mount, close-coupled pumps. Both pumps are duty units alternating automatically as a lead or lag pump. The Forest Shade Pump Station was constructed in 1979 to eliminate possible sewage overflows to Lake Gregory during storm conditions and to serve future unsewered areas. It is located east of Forest Shade Drive and south of Lake Drive, and operates only when sewage backs up in the gravity trunk main along Lake Gregory and overflows into the wet well. During 1989, the pump station was in operation a total of 16 hours. Of this total, about 8 hours was for exercising and testing the pumps. The Forest Shade Pump Station discharges through a 10-inch force main located in Lake Drive to a vault located just west of Lake Gregory Dam. The force main is parallel to the existing 15-inch gravity trunk sewer that follows the north shoreline of the lake to the same vault. Flow from the vault can be diverted to both or either one of two parallel gravity trunk sewers to the Huston Creek Treatment Plant. The pump station, force main and a parallel trunk sewer were constructed in 1981. A parallel 8-inch force main was installed before 2000. The Bernard
Drive Pump Station was constructed prior to 2000 and provides sewer service
to three homes on Bernard Drive that previously had been served by gravity
until the gravity pipeline was washed out and no longer provided service.
This station pumps less than 500 gallons per day, is approximately 2
horsepower, and lifts the sewage approximately 30 feet to the Bernard Drive
gravity collection system. |
