Grit
Water Environment Services ("WES") manages grit and screenings produced from three wastewater
treatment plants: Kellogg Creek, Tri-City and Hoodland wastewater treatment plants. Screens remove
larger material coming into the plant. The material collected is the screenings. Grit consists of solids that
settle out after the screens at the beginning of the treatment process. Screenings and grit are normal byproducts of wastewater primary treatment and are typically hauled to landfill for disposal.
WES also manages the solids captured from the cleaning of the storm water collection system in select
parts of the service areas. This material is also hauled to landfill for disposal. Screenings, grit and
collection system solids are decanted to achieve the required solids content for landfill and are co- mingled
for final disposal.
Composition of grit and collection system solids includes sand, gravel, other mineral matter and minimally
putrescible organics such as eggshells, bone chips, seeds, fruit rinds, coffee grounds. All three wastewater
treatment plants move approximately 24,000 tons annually.
Biosolids
The Kellogg Creek and Tri-City wastewater treatment plants produce Class B dewatered biosolids.
Typically, this material is hauled to Sherman County and land applied to agricultural fields. In wet/winter
weather, the fields may not be accessible. At these times the dewatered biosolids are diverted to landfill.
Spent hydrogen sulfide (H2S) media
The air scrubber at the Tri-City wastewater treatment plant uses an H2S-based media to capture hydrogen
sulfide vapors. We are currently disposing of this material as a non-hazardous waste. The Safety Data
Sheet, change out protocols (which includes disposal) and analytical results are available on request.
We expect to generate this waste stream 2-3 times per year. MINIMUM QUALIFICATIONS:
In order to qualify as a Responsive Bidder, the Bidder needs to meet the minimum qualifications below:
Possess any required permits to receive and dispose of co-mingled screenings, grit and collection system
solids. Protest of Specifications Deadline .............................................................................. May 2, 2023
