On-Call Landfill Liner System Repair Services

The County of Sacramento, Department of Waste Management & Recycling (DWMR) is soliciting proposals from qualified liner system installation firms to perform geosynthetic liner repair services for the County of Sacramento Kiefer Landfill facility (KLF) on an on-call basis. The KLF is located in southeastern Sacramento County at 12701 Kiefer Boulevard, Sloughhouse, California 95683 as shown on Attachment B - Site Vicinity Map.

Damage to the liner system affects the integrity of this environmental barrier and shall be repaired before covering the damaged liner with waste. Due to limitations on locations for active waste placement, repairs may be of a very high priority to maintain service for the waste stream entering the landfill. As such, emergency repairs will be needed on an on-call basis to keep the landfill operation running efficiently. However, repair services will only be required if damage occurs to the landfill base liner system.

The County owns and operates the KLF for the disposal of Class III municipal solid waste, servicing the residences and businesses within the County of Sacramento and nearby cities. Periodically, the KLF extends the landfill base liner system to incorporate more airspace to deposit waste. The landfill liner system is a subsurface barrier that contains waste and waste constituents from being released into the surrounding environment.

The Kiefer Landfill is permitted for base liner systems in Modules M1L through M11. Module M1 (the original unlined area) was opened for waste fill operations in the summer of 1967. Module M-1L was opened for waste fill operations in March 1994 with the initial base liner system. Currently, landfilling is occurring in Module M4. Modules 5 through 11 will be constructed in the future to meet the local demand for disposal service.

Since the landfill liner has been constructed in multiple phases, the liner system components and material types vary. A summary of the various liner system components is included with this request for proposals as Attachment A - Table 1 Base Liner System Components.
