Gunlock Groundwater Treatment Plant

Project Overview

VanCon built a new groundwater treatment facility to filter arsenic, manganese, and iron from drinking water. The project included a treatment building with a chlorine gas feed system and ferric chloride dosing, and two parallel horizontal 4-cell pressure vessels with anthracite filter material with 6 MGD capacity. The project also included two backwash clarifiers, a pump station, a decant pump station, four 40-foot by 201-foot drying beds, 1,496 feet of 24-inch, 4,763 feet of 20-inch and 400-feet of 10 to 16-inch concrete lined ductile iron pipe.
