Specifications include, but are not limited to: Clean Water Services (District) wishes to purchase polymer products under a one-year contract that includes an option to renew for up to two additional one-year periods. The polymer will be used at District's wastewater treatment facilities primarily to dewater a mix of anaerobically digested primary, secondary and tertiary sludges via centrifuges. Additional products will be supplied by the selected vendors for thickening primary and secondary sludges (gravity belt thickeners and rotary drum thickeners) and liquids clarification of secondary effluent per the District’s needs. This is a multi-step Invitation to Bid (ITB) that involves bench and performance testing of vendor products to determine their ability to meet District specifications in the first step. In the second step, District will invite vendors with qualified products to submit a price bid for consideration. Interested vendors must submit products for performance testing at both of the District's treatment facilities, and they must be the manufacturer of the product or an authorized distributor. Only the vendors whose products have been performance tested and met District specifications will be invited to submit bids. District may award multiple contracts under this procurement. Vendors may bench test products. Testing is conducted in a laboratory environment with District-provided dewatering feed samples to help vendors decide which polymer products to submit for performance testing.
