Beyaz & Patel performed conceptual layout and analysis of a proposed leachate collection system for the County of Sacramento at the Kiefer Landfill. The evaluation involved alternative layouts that included onsite leachate conveyance piping from the leachate collector sumps to a discharge manhole located near the entrance to the landfill. This discharge manhole included a sanitary sewer connection to a nearby proposed sewer line.
For each alternative, we reviewed existing and proposed drawings of improvements, such as roadway and subsurface utilities, and reviewed grade considerations to determine lift station and piping requirements. Work also involved review of permitting requirements and evaluation of operational, construction and maintenance considerations on each alternative. We also prepared order-of-magnitude cost estimates and scheduling of design and construction phases.
