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 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.

Upcoming projects

Johnson Drive, Place and Court - waterline replacement  

Beginning in late May 2017, Castle Rock Water plans to replace aging waterlines on Johnson Drive, Place and Court, at a cost of $246,810. View location map. With replacement of the waterlines, crews are also bringing 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. All of the main waterlines and the service lines connecting to each household meter will be replaced. The waterline replacement work is scheduled for 10 weeks and is expected to be completed around the end of July weather dependent.  


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 to us. Detours for the public may be necessary, but local access for residents at all times will be a priority. There will be planned water outages when the new waterline is connected to the system, but advance notice (at least 48 hours) will be given to affected households, and every attempt will be made to minimize the duration of the outages. Additionally, during construction, residents in this area may experience intermittent water outages. We apologize for the inconvenience and are making every effort to minimize any service disruptions.


This waterline replacement is taking place in advance of the pavement maintenance scheduled for this neighborhood. The Public Works Department will restore the roads with new asphalt, as part of the Pavement Maintenance Program, in late July or early August. As with
all construction, schedules may be affected by weather and other delays.



Completed projects
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. 



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.
