  • Water Supply

ECCV receives its water supply from three distrinct sources:

  • Groundwater from deep aquifers in the Denver Basin (non-renewable water).
  • Groundwater from the Beebe Draw aquifer (renewable water).
  • Surface water from Denver Water, which is a leased supply of renewable water.

Deep Aquifers

ECCV uses approximately 86 wells within the District and in its Western Well Field. In-District wells and the Western Well Field each produce roughly 30 percent of the District's overall water supply, making deep aquifers the source of approximately 60 percent of ECCV's water. Aquifers are open spaces, typically filled with gravel and sand, in underground bedrock layers that contain water. Groundwater from aquifers typically needs little treatment to meet drinking water standards because it is not exposed to environmental pollutants. Deep aquifers are considered a "non-renewable" source because they cannot be replenished with rainfall or snow melt as quickly as the water is withdrawn.

Northern Project

This project delivers renewable water from the South Platte River and comprises 30 percent of ECCV's annual water supply. ECCV stores this water in the Beebe Draw aquifer near Brighton. When needed, ECCV's Northern Water Treatment Plant uses twelve wells to extract the water. ECCV then treats the water with reverse osmosis and disinfection. Once treated, the water is transported through a 31-mile pipeline to our distribution system.

Denver Water

ECCV currently receives approximately 10 percent of its water supply from Denver Water through two seperate connections to the Denver System; one near Denver International Airport, and another in Highlands Ranch. This resources is surface water that has been treated by one of Denver's state-of-the-art water treatment facilities.

Blended Supplies

ECCV blends its water supplies before distributing it to our customers. All of the water sources are tested regularly and meet all State and Federal drinking water regulations.


Unique Characteristics of ECCV Water

The mineral content of ECCV's water varies from the three sources - enough to cause taste and odor differences in the water as wells are rotated and supplied blended. ECCV's treatment plant provides more consistency to the water supply and less variation in the taste and odor of the water.

Another unique characteristic of ECCV's deep groundwater supply is that it comes out of the aquifer to a warm 86 to 89 degrees Fahrenheit, winter or summer. ECCV recommends keeping a pitcher of water in the refrigerator to provide a cold glass of water any time. This also provides an added benefit of reducing the effect of tastes and odors that may be noticeable at warmer temperatures.
