Waterline Program

New waterline installation

Red Hawk Reuse Line

Planned for construction May to November 2019, the Red Hawk reuse line is a 3.4 miles-long, 8-inch diameter reuse waterline to take treated wastewater from the Plum Creek Water Reclamation Authority plant to the Red Hawk Golf Course to be used for irrigation. While Red Hawk Golf Course has its own well, during the height of summer heat, supplemental water is often supplied by Castle Rock Water. Instead of using treated drinking water, this non-potable reuse water will help supplement the additional irrigation needed.  

The pipeline project was awarded to Global Underground for an approximate project cost of $2.95 million. The project will involve a combination of horizontal directionally drilled pipe under major roadways and drainage crossings, a bored crossing under the railroad, and also open-cut trenched installation.

The reuse pipeline was substantially completed in October. Delivery of reclaimed water to the Red Hawk Golf Course began in November 2019.

Water distribution rehabilitation

Castle Rock Water identifies water distribution pipe and appurtenances for rehabilitation based on a history of leaks, increased annual maintenance, age, and condition. Hydraulic modeling and fire flow testing sometimes determines when a pipe should be replaced with a larger-size pipe to deliver more flow. Pipeline repairs always involve open-cut trench work in the streets, so residents should be aware and obey any posted traffic signs.

With water system repairs, the water system must be shut down to relieve pressure and make the work area safe. Castle Rock Water will provide notice for planned shutdowns, and complete repairs as quickly as possible.

PRV Improvements Project

The PRV Improvements Project is the replacement of pressure regulating valves (PRV) to ensure consistent water pressure throughout the water distribution system. Two projects to replace existing PRV vaults are planned before year-end 2019:  the Oakwood PRV located near the intersection of Mountain View Drive and Oakwood Drive and the Mt. Royal PRV located near the intersection of Mt. Royal Drive and Plum Creek Boulevard. Both PRV vaults were constructed in the late 1980’s and are not constructed per current Town standards. This project also includes the installation of a new check valve near the intersection of Mt. Royal Drive and W. Prestwick Way. 

Detours may be encountered at construction sites. Residents may experience some minor disruption to water service during construction hours (7 a.m. to 6 p.m.). Prior notice will be provided for planned service distruptions.

This project was awarded to Global Underground for an approximate cost of $355,575.

Some completed projects

Johnson Drive, Place and Court - waterline replacement

In the summer of 2017, Castle Rock Water replaced aging waterlines on Johnson Drive, Place and Court, at a cost of $246,810. View location map. With replacement of the waterlines, crews also brought the number of hydrants and valves in the neighborhood up to current standards, making the area safer and less susceptible to water outages in the future. 

This project took place in advance of the pavement maintenance scheduled for this neighborhood. The Public Works Department restored the roads with new asphalt following the waterline replacement work.  By coordinating the road work with the waterline replacement project, the Town was able to save money and limit inconveniences to residents.

Prairie Hawk Drive - waterline distribution upgrade

In January of 2017, Castle Rock Water installed a new waterline along Prairie Hawk Drive, between Atchison Way and Topeka Way, at a cost of $163,800. View location map. This project looped the two waterlines in Atchison Way and Topeka Way.
