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

Renewable Water

The Castle Pines North Metro District owns and has unfettered access to 1,006 acre-feet of renewable water stored in Chatfield Reservoir. Our neighbors to the north, the Centennial Water & Sanitation District (Highlands Ranch), treats our renewable water, which we then pump through our existing Interconnect pump station and pipeline into our water distribution system. We typically utilize those renewable water resources from October 1st through April 30th of each year.

Water Sources & Infrastructure

Water is delivered to the CPNMD water treatment plant which produces an average of two million gallons of water per day, except in peak summer months when four million gallons of water per day is more common. Treated water is then stored in the District's two storage tanks, and supplied to customers on demand.

Water in CPNMD originates from two Denver Basin underground aquifers, which include the Arapahoe Lower Dawson and Denver basins. These sources are the result of water rights that date back to the formation of the District. In 2010, Hock Hocking (Park County, Colorado) and Upper Platte River rights were purchased to increase the community’s water assets to include surface water. The District has 10 active water wells located in the community that are generally only used in the summer months (May- October).  The remainder of the year we utilize our interconnect with Centennial Water and Sanitation District to take advantage of our renewable water stored in Chatfield reservoir. 

Water Rates & Budget

All CPNMD water customers have individualized water budgets based primarily on lot size. Additionally, all utility customers pay a customer service charge to offset metering and billing expenses, as well as a capital improvement fee designed to help pay for future renewable water supplies. CPNMD customers are currently charged for sewer based on their average winter water consumption.To help our community conserve water, we budget projected water usage for all customers. The water budget in CPNMD is designed to promote conservation and increase awareness of the amount of water a home needs for irrigation. The average home in the District uses more than four times more water in summer months than in winter, primarily for landscape irrigation.

The water budget is designed to allocate the amount of water for irrigation needed based on the time of year and the lot size. During the seven-month irrigation season (April through October), all CPNMD residents are

From October 1st through April 30th of each year, we utilize our renewable water stored in Chatfield Reservoir that travels through the Centennial Water & Sanitation District’s water-treatment system, through our existing interconnect pipeline, and into our water distribution system. From May 1st through September 30th of each year, we utilize our deep-water wells in the Denver Basin Aquifer System.
