Approve a five-year agreement with the City of Sacramento, Department of Utilities, for acceptance of Drinking Water Treatment Plant residuals at the Yolo County Central Landfill. (No general fund impact; estimated total revenue of $500,000 to the sanitation enterprise fund) (Echiburú/Kieffer)

The City of Sacramento (city) requires the disposal services of a permitted landfill or disposal site for the waste material (residuals) which are generated during the water treatment process for the city's drinking water.  The Yolo County Central Landfill (landfill) is the closest location for proper handling of the residuals.  The agreement identifies the city's and county's respective responsibilities and the fees associated with the scope of services described in the agreement. 

The city has two drinking water treatment plants that provide approximately 90 percent of the drinking water to its residents. Part of the treatment process involves the filtering and settling of sediments in the water after it is pumped from the Sacramento and American Rivers. This process generates approximately 6,000 to 9,000 tons of waste material each year.  Due to the addition of Alum to the water to aid in settling and removing the solids, the city is required to use a permitted disposal facility.
