Parks staff to upgrade Lions Park dechlorination system to meet DNR guidance
Summary
Staff said they will install a feeder-style dechlorination unit (estimated about $2,500) and riprap along Bear Creek to improve aeration and sunlight exposure, keeping wastewater discharge in compliance with DNR rules and avoiding a wastewater discharge permit.
Parks staff described plans to replace the current dechlorination setup at Lions Park with a feeder‑style system that should reduce consumable use and make the discharge less likely to require a wastewater permit. "What we're getting is like a feeder system," a parks staff member said, describing a multi‑tube pellet feeder approach; staff estimated the equipment and containment cost at roughly $2,500 and said they would build a small pump house around the unit for access control.
Staff also discussed adding riprap along the drainage stream and Bear Creek where it passes through park land to increase aeration and exposure to sunlight, which they said would help meet DNR expectations for water released from park operations. The board noted that avoiding the need for a wastewater discharge permit is preferable because permit inspections and enforcement would carry extra costs and requirements.
