River Ridge approves $7,026 Premier Lakes work order to repair nano bubblers
Summary
After reviewing a manufacturer proposal for $25,000, the board approved Premier Lakes’ one-time work order to repair pumps, compressors and check valves on three lake aeration systems for $7,026, with a one-year warranty discussion noted.
Bill Kurth of Premier Lakes reported the lakes and dry retention areas are generally in good condition and said the manufacturer Mollier proposed $25,000 to replace nano bubble units with like-for-like parts. As an alternative, Premier offered a One‑Time Work Order to replace the nonstandard 8‑horsepower pumps, aeration compressors and check valves so staff can evaluate system performance. On motion by Supervisor Kurt Blumenthal, seconded by Supervisor Robert Twombly, the board approved Premier Lakes’ amended One‑Time Work Order to repair the nano bubble machines on Lakes H1‑A, H1‑B and E7‑A in the amount of $7,026.
Discussion included the warranty length on pumps and compressors and identification of Lake H1‑B as a priority. Supervisor Terry Mountford also raised concern about invasive vegetation at Lakes 9, E3‑C and Conservation B‑2191 and asked Kurth to inspect and treat those areas as needed.
