Pre-qualified named Equipment Suppliers are invited to submit a proposal to the Town of Bennett, Colorado (OWNER or Town) to furnish services and equipment in accordance with the Request for Proposal (RFP) - Membrane Bioreactor (MBR) System for Town of Bennett Water Reclamation and Resource Recovery Facility (WRRRF) Project.
The Town of Bennett (Town) operates a municipal WRRRF permitted for hydraulic and organic capacities of 0.40 million gallons per day (mgd) and 854 pounds per day (ppd) biochemical oxygen demand (BOD5), respectively. The WRRRF is located at 805 4th Street in the Town of Bennett, Colorado. The facility discharges treated effluent to West Sand Creek, a tributary of Lost Creek per the Colorado Discharge Permit System (CDPS) general discharge permit COG589069 administered by the Colorado Department of Public Health and Environment (CDPHE). Bennett’s lagoon treatment system was upgraded in 2018 to a Sanitaire ICEASTM Sequencing Batch Reactor (SBR) System. The Town’s current WRRRF facility consists of influent flow metering, automatic screening, grit removal, an advanced SBR biological treatment process capable of secondary treatment and biological nutrient removal (BNR), effluent equalization, ultraviolet (UV) disinfection, and biosolids handling using a solids holding tank and dewatering screw press. The currently proposed facility expansion will increase the total hydraulic capacity to 0.99 mgd maximum month flow and increase the organic capacity to 2,972 ppd BOD5. In general, the expanded WRRRF will include the following components: ▪ Influent lift station. ▪ Expanded headworks building with fine screening, grit removal, and flow monitoring. ▪ Re-configured biological secondary treatment. ▪ Membrane bioreactor (MBR) system. ▪ In-line ultraviolet (UV) disinfection system. ▪ Existing aerated sludge holding. ▪ Existing biosolids dewatering. ▪ Upgraded electrical, instrumentation, and controls system
