In 2009, the Parker Water and Sanitation District (District) became a regional partner in the Water Infrastructure and Supply Efficiency (WISE) Project with Aurora Water, Denver Water and the South Metro Water Supply Authority. Through this project, the District will receive an average of 1,200 acre-feet of potable water each year. An acre-foot is about 326,000 gallons and enough to supply two families of four for one year.
In order to access this additional water supply the District must first create a system to receive the water, disinfect the water to make the water from Parker, Aurora and Denver compatible, and to convey the water to our customers. The project to construct this system of pipes and facilities to receive, disinfect, and transport the water is called the Water Resource Centralization Project (WRCP).
WRCP System Components
· The recently completed four-mile Ridgegate Line, which will bring renewable surface water to Parker from Aurora and Denver. This water was acquired through the WISE Project.
· Approximately nine miles of new pipeline to consolidate existing District groundwater sources and to bring them to three centralized disinfection facilities.
· A four-mile pipeline and pump station to convey WISE water to our customers and other regional water providers.
· Changes in water disinfection facilities and processes that will make our water compatible with regional water providers including Denver, Aurora and Castle Rock.
Benefits to the District’s Customers:
· More consistent water quality. By consolidating the groundwater treatment at three facilities, customers will realize more consistent water quality throughout the system.
· Renewable water sources. Reliance upon non-renewable groundwater is not a sustainable practice. While the groundwater system will remain an important part of the District’s water portfolio, the long-term goal is to have 75 percent of the water provided to our customers be from renewable sources.
· Diversification of the water supply. The District is participating in the WRCP project as part of a regional solution to provide renewable water supplies. This regional cooperation ensures a reliable water supply now and far into the future.
Locations of Pipelines/Purification Facilities
Preliminary routes of the proposed pipelines and the location of the centralized facilities and pump station are noted on the map.
This project is being funded through a combination of District customer rates, developer tap fees, and regional partners.
Monochloramine in Water Treatment Process
Disinfection is a very important part of the water treatment process that keeps water safe. To protect public health, the District currently maintains chlorine in the water as it moves through the system to the end user. As part of the WRCP, the District will transition from chlorine to using monochloramine, which is an effective, affordable and longer-lasting water disinfectant. This change will make the water compatible with Castle Rock, Denver and Aurora, which already use monochloramine.
Water treated with monochloramine often tastes better and has fewer odor issues than water only treated with chlorine. Water treated with monochloramine is safe and beneficial for all typical uses. Monochloramine, like chlorine, must be removed from water before it is used for two specific purposes:
