2020-007 - Biosolids Loading, Hauling, and Disposal Services

The Town of Mead is soliciting proposals from Contractors for services associated with land application of treated sludge (biosolids) generated by the Mead wastewater treatment plant (WWTP).  The services include loading, hauling, and land applying biosolids and keeping records and reports as required by state and federal regulations.  The Town shall choose a Contractor based on an evaluation of proposals as described in this Request for Proposal (RFP).  The selected Contractor shall have the opportunity to enter a one (1) year contract with the Town, renewable for up to three (3) additional consecutive one (1) year terms upon mutual agreement of the parties.
The WWTP is rated for a treatment capacity of 0.5 MGD and 1,286 lbs/day BOD5 and consists of preliminary treatment (fine screening and grit removal), biological treatment using sequencing batch reactors, UV disinfection, and aerobic digestion. The WWTP produced 1,144,000 gallons of sludge in 2019.  The total solids content was 1.26% yielding approximately 120,160 lbs of dry sludge.  The sludge is treated by aerobic digestion at the WWTP.  Digestion utilizes bacteria to metabolize and stabilize the biosolids.  After digestion is complete, the biosolids meet federal and state requirements for Class B Biosolids land application on agricultural land.  The digested biosolids have a solids content between one and three percent for hauling or further processing.
