In Castle Rock, leaks in the street go to Castle Rock Water, while a leak on the buried line across your property is generally a private plumbing repair. The town's published material doesn't state the exact handoff point, so call the utility first if water is surfacing near the street. Call the number on this page to be connected with a local plumber in Castle Rock.

Castle Rock's water setup
Castle Rock Water is the town's own utility, drawing mostly on deep Denver Basin groundwater wells and adding renewable supplies such as Plum Creek diversions and reuse water. It also runs a separate system for Bell Mountain Ranch. Some addresses with a Castle Rock mailing address, such as The Village at Castle Pines, are served by other districts, so check whose name is on your water bill before calling anyone.
Steps to take now
- Shut the water off if it's flowing. Close the main valve inside the house.
- Figure out where the water is. A leak in the street is reported to Castle Rock Water at 720-733-6000; after hours, press 1.
- Check the meter. With every fixture and the irrigation off, any movement means water is escaping.
- Photograph the wet area. It helps the plumber, and it helps if the utility needs to confirm where the leak sits.
- Ask about permits. Confirm with the Town of Castle Rock building office whether the repair needs a permit.
What the symptoms usually mean
| Symptom | Likely cause |
|---|---|
| Wet ground near the street or curb | Possible utility-side leak; report it to Castle Rock Water |
| Soggy strip between the meter and the house | Leak in the private service line |
| Pressure down at every fixture | Leak in the buried line or a restricted valve |
| Meter moving with all water off | Leak past the meter, in the yard or the house |
| Water at the foundation where the pipe enters | Failed fitting at the wall |
Cost factors
Castle Rock is a fast-growing town on I-25, and many homes sit on hilly lots around the butte and in neighborhoods such as The Meadows. Slopes and rock can make digging slower, and long setbacks add pipe and excavation. A single failed fitting costs much less than a whole new service, while a line that has leaked more than once is usually a candidate for replacement. Castle Rock Water reports that its distribution service lines are non-lead, so there's no lead program to factor in. Restoring sod, sprinklers, pavers or a driveway and any permit the town requires also affect the total.
