The Castle Pines North Metropolitan District (CPNMD) is dedicated to providing safe, reliable water to all residents and businesses throughout the community.

Water Sources & Infrastructure

Water in CPNMD originates from Denver Basin underground aquifers, which include the Arapahoe Lower Dawson and Denver basins. We also have access to 1,006 acre-feet of renewable water stored in Chatfield Reservoir. Water is delivered to the CPNMD water treatment plant which produces up to four and a half million gallons of water during the peak summer months. Treated water is then stored in the District's two storage tanks, and supplied to customers on demand.

More info on our sources and treatment below.
