Lone Tree water at a glance
Lone Tree is a planned, newer city at the I-25 and C-470 junction, built around Park Meadows and the RidgeGate community. The city lists three water and sanitation districts, divided mostly by the interstate. Southgate, a Denver Water read-and-bill distributor, serves the west side; Parker Water and Sanitation District serves the east; and Northern Douglas County Water and Sanitation District serves some Terra Ridge homes along Indian Wells Drive.
Steps to take now
- Shut off the water at the main valve in the house if it's flowing.
- Identify your district. Use I-25 as a guide and confirm on your bill.
- Report leaks at the main. West-side residents can reach Southgate at 303-779-0261.
- Confirm the leak with the meter. Everything off, meter moving, means water is escaping.
- Check the permit rules. Lone Tree's Building Division takes applications online through Accela.
Symptoms and causes
| Symptom | Likely cause |
|---|---|
| Wet ground near the curb | Possible district-side leak; call your district |
| Wet strip between meter and house | Leak in the private service line |
| Low pressure throughout | Leak in the buried line or a partly closed valve |
| Meter moving with no use | Leak past the meter |
| Water near the foundation | Fitting failure where the line enters |
Cost factors
Southgate reminds property owners that they own the buried water service lines and sewer laterals serving their property, so on the west side the repair is yours from the service connection to the house. The east-side and Terra Ridge districts' rules aren't on file here, so ask them if the leak is near the meter. Because Lone Tree's housing is relatively new, failures tend to come from fittings, soil settling or damage during landscaping rather than old pipe. Lone Tree requires permits for any work on plumbing systems, including replacing them, though repairing a supply leak typically doesn't need one; the Building Division is at 720-390-5211. Run length, depth, hardscape over the line and whether one section or the full line is replaced set the rest of the cost. Restoring sod, sprinkler heads and decorative rock along the route is often a bigger share of the bill than the pipe itself.
