Waldo Utility Board approves vouchers, hears wastewater plant phosphorus‑reduction pilot plan
Summary
At its Dec. 8 meeting the Waldo Water & Sewer Utility Board approved routine financial items and heard an operations report in which the operator described a planned pilot using an 80% alum/20% ferric mix to lower phosphorus at the wastewater plant and proposed a March meeting about water trading credits.
The Waldo Water & Sewer Utility Board on Dec. 8 approved routine finance items and heard that the village’s wastewater plant will start a pilot test aimed at reducing phosphorus levels.
Operator‑In‑Charge Bruce Neerhof, participating by phone, told the board that November lab results showed all effluent parameters met regulatory limits at the wastewater treatment plant. Neerhof said Great Lakes is scheduled to clean the wet well in the next couple of weeks and that the water tower mixer is running. He also reported there has been “high turnover with running water at the WWTP,” a staffing/operation note the board recorded.
Neerhof described recent jar testing of chemical options for phosphorus removal and said an 80% alum, 20% ferric mix performed best in their tests. The operator said staff will set up a 55‑gallon drum and begin a pilot by adding roughly one gallon per day to the process to try to get phosphorus below the plant’s current 6.4 mg/l limit; he estimated the change should save about $70 per month compared with running village water for the same purpose. Neerhof also said he would like to hold a meeting with potential farmers about water trading credits in March to discuss options and participation.
On routine business the board approved the Oct. 13, 2025 minutes; Trustee Dennis Reinemann moved to approve November’s Treasurer’s report and President Thomas seconded; the motion carried. President Thomas moved to pay vouchers 9430–9438 in the amount of $11,032.35; Trustee Reinemann seconded and the motion carried.
The clerk recorded no public comment and no correspondence or items were proposed for the next meeting. The board adjourned at 7:57 p.m.
What’s next: Neerhof’s pilot and the proposed March meeting with farmers are the next operational steps noted by the board; no formal vote on the pilot was recorded in the minutes.
