The Ridgefield Water Pollution Control Authority is hosting a public information hearing on Saturday about the town's wastewater treatment plant upgrades. Planning for the facility upgrades and capital needs has been underway for several years. Ridgefield residents will get a chance to officially weigh in on the upgrades during a referendum vote scheduled for November. Authority members will provide information on Saturday about what is proposed, why the upgrades are necessary, the estimated cost, what funding assistance is being offered, project schedule, and other relevant details. The hearing is at Ridgefield Town Hall at 10am.
