Who We Are and What We Do

The Meridian Metropolitan District (MMD) is a quasi-municipal corporation and a political subdivision of the State of Colorado. MMD was created pursuant to Article 1 of Title 32 C.R.S. for the purpose of providing complete water supply and sanitary sewer systems for the MMD customers and was formed in 1980. MMD also maintains certain landscaped medians, parks, greenbelts, open spaces and trail systems. 

Where Your Water Comes From

Since 1982 MMD has delivered reliable and safe drinking water to its commercial and residential customers for domestic use. MMD also treats 100% of the collected wastewater for use as reclaimed irrigation water within the District. The reclaimed irrigation water is currently used on the golf course, commercial properties, parks and common areas. Moreover, MMD has already acquired fully adjudicated water rights to continue to provide these resources through currently estimated complete build-out of the District.

MMD is committed to efficient use of all its water resources and will continue to implement its water conservation plan and the covenants enforced by the Design Control Committee (DCC) as key elements of an integrated water resources planning and management approach. That planning also includes reviewing options with respect to additional water, both renewable and groundwater.

MMD’s existing groundwater supplies are derived from wells drilled in the Denver Basin aquifer system. The Denver Basin aquifers underlying the service area include the Dawson, Denver, Arapahoe and Laramie-Fox Hills formations.

All groundwater development to meet MMD’s water demands occurs within the district boundaries. Wells are drilled incrementally as necessitated by development. The groundwater supplies developed by MMD require minimal treatment to meet drinking water standards. Treatment to meet regulatory requirements for disinfection is done at both booster pump stations.

Renewable Water Supply

Award Winning Efficiency & Conservation

MMD is a member of the South Metro Water Supply Authority which is comprised of 13 entities. These entities have joined forces to supply customers with more water while minimizing the need to develop new infrastructure and water rights.

MMD is also a participant in the WISE Partnership. WISE, which stands for Water, Infrastructure and Supply Efficiency, is a regional partnership between Aurora Water, Denver Water, and 10 South Metro entities. WISE provides a new water supply by combining unused capacities in Aurora Water’s Prairie Waters Project with unused water supplies from Denver and Aurora. During the years Denver and Aurora have available supplies, and when excess capacity is available in Prairie Waters, the 10 South Metro entities can buy the unused water to help reduce its reliance on nonrenewable groundwater.

MMD is also pursuing Aquifer Storage and Recovery, or ASR, which is the injection of treated drinking water into an aquifer for later recovery and use. An aquifer is an underground layer of sand, gravel or rock through which water can pass and is stored. The concept of ASR is similar to a savings account at a bank — drinking water is injected (deposited) during wet years and stored indefinitely. During droughts, that same water is extracted (withdrawn).

Award Winning Efficiency & Conservation

MMD’s approach to water resource planning and management integrates four categories which are governed by the District: Water Supply and Production, Water Treatment and Distribution, Wastewater Collection and Treatment, and Water Reuse. MMD’s philosophy is to provide a balanced program which provides efficient management throughout the District.

Since 1982 MMD has delivered reliable and safe potable water to its commercial and residential customers for domestic use. MMD treats 100% of the collected wastewater for use as reclaimed irrigation water within the District. The reclaimed irrigation water is currently used on the golf course, commercial properties, parks and common areas. Moreover, MMD has already acquired fully adjudicated water rights to continue to provide these resources through currently estimated complete build-out of the District.

MMD is committed to efficient use of all its water resources and will continue to implement Water Conservation Policies and the covenants enforced by the Design Control Committee (DCC) as key elements of an integrated water resources planning and management approach. That planning also includes reviewing options with respect to additional water, both renewable and groundwater. The extent to which these options are pursued will be largely determined by a combination of economics, opportunities through partnerships and cost-effectiveness to our customers.
