Waterline rehabilitation program

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 shut down to relieve pressure and make the work area safe. Castle Rock Water will provides notice for planned shutdowns, and complete repairs as quickly as possible.

Upcoming projects

Prairie Hawk Drive - waterline distribution upgrade

In January of 2017, Castle Rock Water plans to install a new waterline along Prairie Hawk Drive, between Atchison Way and Topeka Way, at a cost of $163,800. View location map. This project will loop the two waterlines in Atchison Way and Topeka Way. The work is expected to take approximately four weeks to complete. Over the course of the project, there will be construction activity during the day (generally Monday through Friday, 7 a.m. to 6 p.m.). Work zone protection and traffic control will be in place, as your safety and the safety of workers is important. Please be patient and kindly respect and adhere to all traffic signage.  


There will be planned water outages when the new waterline is connected into the system, but advance notice (at least 48 hours) will be given and every attempt will be made to minimize the duration of the outages.



Completed projects
Caprice Drive / Caprice Court and Malibu - waterline replacement

In 2014, Castle Rock Water completed the replacement of 2,093 linear feet of old, undersized waterline in Caprice Drive, Caprice Court and Malibu Street from 6-inch pipe to 8-inch pipe, at a cost of $461,333. The area is largely industrial and commercial properties. Modeling and fire flow testing demonstrated the existing pipes were undersized to provide for a minimum 1,500 gallons per minute fire flow. An 8-inch pipe carries almost twice the flow as a 6-inch pipe.

Jerry Street from Sixth Street to Eighth Street - waterline replacement


During 2013, the Town replaced undersized 6-inch water mains in Jerry Street, from Sixth Street to Eighth Street, with larger 8-inch mains. A water main was also installed in Sixth Street between Perry and Wilcox streets to complete water line looping in that area and improve fire flow capabilities. Approximately 1,200 linear feet was installed at a cost of $265,142.

Program cost


The actual cost of the distribution system upgrades program varies from year to year, but $350,000 is budgeted annually.
