Town of Castle Rock Synthetic Turf Project
Back6round
On July 1, 2007, the Water Efficiency Grant Program, which was established under HBOS-1254,
was merged with the Water Conservation Planning Program, which was established under
HB04-1365, to create one Water Efficiency Grant Program under Senate Bill 07-008. Monies in
the Water Efficiency Grant Program Cash Fund may be awarded to water providers and local
governmental entities to aid in developing and implementing Water Conservation Plans and
Drought Mitigation Plans. The Grant Guidelines, adopted by the Board in November 2006,
define water conservation to mean broadly water use efficiency, wise water-use, water
transmission and distribution system efficiency, and supply substitution. The objective of water
conservation is a long-term increase in the productive use of water supply in order to satisfy
water supply needs without compromising desired water services.
Summary of Grant Proposal
The OWCDP received a Water Efficiency Grant application from the Town of Castle Rock, a
covered entity located 30 miles south of Denver, in Douglas County, Colorado. Castle Rock
provides water and wastewater collection services to approximately 44,000 residents and
commercial users. Castle Rock relies on the Denver Basin Aquifer, which supplies water to
much of the south metro area and northern El Paso County, and is anon-renewable water supply.
Although Castle Rock can currently meet its water supply needs, it is projected that continued
use of Denver Basin groundwater as the primary source would result in a continued decline of
groundwater levels. In that event, it is anticipated that the costs to maintain groundwater
production rates (e.g., redrilling wells; increased pumping energy requirements) to meet demands
will escalate to the point that this source is no longer economically viable. Therefore, the Town
of Castle Rock recognizes the significant role water conservation needs to play to ensure
adequate future water supplies.
