Castle Rock Synthetic Turf Project
Application for Water Efficiency Grant
financial benefits relative to the acquisition of new renewable supplies. The 1.5
million gallons of annual water savings achieved through the synthetic turf
project would offset an investment of approximately $220,000 that would
otherwise be required to acquire and deliver an equivalent quantity of renewable
sw-face water supplies.
Landscape irrigation typically comprises over 50 percent of summertime
municipal water system demands in Colorado's urban communities. From a
statewide perspective, this project demonstrates the use of synthetic turf athletic
fields as a practical means of conserving water through the coordination of
multiple parties. The installation of synthetic turf fields on a large scale
throughout Colorado would provide substantial municipal irrigation savings. In
addition, because infrastructure needs are driven largely by peak demands,
offsetting peak irrigation demands would help water providers meet overall
system demands with lower capital investments in peak delivery infrastructure.
This document is an application for CWCB meant monies requesting $86,013 for the
installation of a synthetic turf athletic field at Douglas County Elementary School #45
(Synthetic Turf Project). This application was developed in accordance with CWCB's
"Guidelines for the Water Efficiency Grant Program."
This grant application includes the following major sections:
^ Section 1: Town of Castle Rock Water Demands and Supplies
^ Section 2: Water Conservation
^ Section 3: Synthetic Turf Field Overview
^ Section 4: Scope of Work
^ Section 5: Project Schedule
^ Section 6: Budget Cost Estimate
z Estimated based on the South Metro Water Supply Authority June 2007 Regional Water
Master Plan (mid-term implementation) with an estimated cost of $34,000/AFY of capital and
annualized OEM costs for the delivery, treatment, and storage of renewable water supplies
from the South Platte River near the Brighton area. A cost of $15,000/AFY for the water rights
was assumed. The combined total unit cost of $49,000/AFY was multiplied by a water savings
of 4.5 AFY (1,466 kgal/year) to obtain the total cost savings.
