Treated Water

Carter Lake Filter Plant

Along with the Central Weld County Water District, the District jointly owns and operates two water treatment plants at the south end of Carter Lake. The Carter Lake Filter Plant can deliver up to 50 million gallons per day of treated water. The North Plant, put into service in 1962, can deliver 30 million gallons per day. The South Plant, added in 1995, was originally rated at 10 million gallons per day. An expansion in 2001 doubled its capacity to 20 million gallons. It draws its water from the outlet works of the St. Vrain Supply Canal and Northern Water’s Carter Lake to Broomfield pipeline.
