Title
ITB #26-006 Aquatic Weed Control and Aerator Maintenance - Award
History
The Public Works Department currently maintains eighty-five (85) wet stormwater basins (ponds) throughout the Village. All of these ponds contain at least some amount of aquatic weeds, but due to a variety of factors some ponds are more prone to excessive weed growth than others. Things like basin depth, water turbidity, and the amount of nutrients from resident yards flowing into a pond can all affect the amount of weed growth a pond experiences.
Since 2011, the Village has retained contract services to manage aquatic weeds at a selection of ponds that exhibit excessive weed growth. The purpose of this management is to prevent invasive weeds from outcompeting native aquatic plants, and to prevent ponds from becoming unsightly for nearby residents due to the spread of things like algae. Most recently, the Village contracted with McCloud Aquatics in 2022 to treat a list of thirty-seven (37) ponds for nuisance weed growth and maintain five (5) of the Village’s pond aerators. This contract ran from 2023 through 2025, and during that time several contract change orders were executed that expanded the list of managed basins to forty-one (41) ponds.
