St. Peter council authorizes engineering for wastewater biosolids improvements
Summary
Council approved Bolton & Menk engineering work to redesign biosolids handling at the wastewater treatment plant, shifting from lime pasteurization to a drier process; estimated engineering cost is about $996,000 and the project may qualify for Clean Water Revolving Fund assistance.
The St. Peter City Council on Nov. 24 authorized preliminary design and engineering for biosolids improvements at the city wastewater treatment plant aimed at reducing solids volume and long‑term disposal costs.
Pete and staff described a planned shift from the current lime pasteurization process to a drier treatment and dewatering operation that staff said should produce Class A exceptional quality biosolids. Pete said benefits would include reduced disposal volumes and lower chemical costs, with higher electricity and heating costs expected as a tradeoff. The plan also includes reinstalling an internal wall in the liquid biosolids storage tank to allow staged maintenance and better operational flexibility.
Bolton & Menk will advance plans to roughly bid‑ready levels; staff estimated engineering costs of about $996,000 and said Rice Lake Construction will provide a guaranteed maximum price under a construction manager‑at‑risk approach. Pete said the design should make the project eligible for Clean Water Revolving Fund financing, and staff will return with rate‑impact estimates once design numbers are firmer.
Council approved the design engineering authorization unanimously; staff noted the city is also pursuing bonding and other funding opportunities to reduce rate impacts.
