Design_Drawings_2022_Gas_System_Improvements_final.pdf

The document is a set of design drawings for the Kiefer Landfill 2022 Gas System Improvements project, prepared by the County of Sacramento Community Services Department of Waste Management and Recycling. The project involves the construction of 35 vertical landfill gas extraction wells and approximately 13,929 linear feet of collection piping at the Kiefer Landfill located at 12701 Kiefer Blvd, Sloughhouse, CA 95683. The drawings provide detailed technical specifications for well installation, header connections, road and bench crossings, and overall site layout, including plans for new extraction wells, headers, valves, and piping infrastructure.

The design drawings include comprehensive technical details such as typical well installation methods, header connection specifications, road crossing details, and site-specific positioning of new and existing gas collection infrastructure. The project focuses on improving the landfill's gas extraction and management system, with specific attention to precise engineering specifications like pipe sizes, valve types, and installation techniques. The drawings are dated May 2022 and include detailed notes on construction methods, such as maintaining consistent slope, proper pipe bedding, and specific installation requirements for different components of the gas collection system.
