ARAPAHOE COUNTY, CO, Sept. 22, 2006 -- July marked the completion of the first phase of a major water project that now brings a long-term supply of renewable water to nearly 50,000 people in Arapahoe County, reported CDM Inc. on Aug. 2. Working with the East Cherry Creek Valley Water and Sanitation District, CDM performed pre-design, final design, multi-jurisdictional permitting, and construction management services.

The Northern project -- publicly referred to as H₂06 -- delivers surface water from the South Platte River that will supplement the district's deep aquifer resources and reduce the district's dependency on non-renewable groundwater. Phase I of the project included acquisition of water rights and the construction of a 31-mile pipeline, storage tanks, and two pumping stations. When future phases are complete, the pipeline is expected to carry up to 40 million gallons per day of water per day for the district's customers.

Members of the South Metro Water Supply Authority -- serving the adjacent communities -- partnered in the project by paying the costs to build a larger-than-planned pipeline with capacity to move water into their communities. This collaborative effort enables participating districts to purchase their own water rights and use East Cherry Valley Water and Sanitation District's waterline to bring the resources to their customers.

"Securing renewable water has been of paramount importance to us for years, as the district has relied on wells tapping finite water supplies in underground aquifers for the past 40 years," said David Kaunisto, East Cherry Creek Valley Water and Sanitation District manager. "Water issues are often contentious; however, partnership has been the cornerstone of this effort."
