Kiefer Landfill Wastewater Force Main Project

Kiefer Landfill Wastewater Force Main Project

The Kiefer Landfill Wastewater Force Main Project consists of a 2.6 mile long, six inch diameter force main transmission pipeline and pumping system, which connects to the 250,000-gallon leachate storage tank at the Kiefer Landfill . The pipeline will travel west within a subsurface trench approximately 18 inches wide and three to four feet deep, within the right-of-way of Kiefer Boulevard and will terminate at the SASD pump station S138 in the City of Rancho Cordova1. The construction schedule for the proposed project is approximately six (6) months. The design of the pipeline and pump station is based on existing leachate generation and estimates of future leachate generation. A flow rate of 40,000 gallons per day (gpd) was used as a design average flow with a peak rate of 100,000 gpd during periods of high leachate generation. Approximately 2,400 cubic yards of soil will be exhumed in the trenching process. If the soil is of suitable quality, it will be utilized as backfill; otherwise, the soil will be disposed of at Kiefer Landfill. If the soil is disposed of, approximately 2,400 cubic yards of gravel will be used as backfill. Construction methods vary depending on the location along the pipeline and include open cut trench and horizontal directional drilling techniques. Where feasible, construction will avoid impacts to the wetland areas. The projected construction timeframe is six months during daytime hours only. The contractor staging area will be located within the alignment and at the Kiefer Landfill.
