During a Lone Tree plumbing emergency, close the main valve, and if you smell gas, leave the house and call 911 and Xcel Energy at 1-800-895-2999. Then call the number on this page to be connected with a local plumber in Lone Tree.

Lone Tree is a newer planned city at the I-25 and C-470 junction, and it has no city water department. West of I-25, water and sewer come from Southgate Water and Sanitation Districts, which distribute water provided, treated and tested by Denver Water. East of I-25, Parker Water and Sanitation District serves homes, and part of Terra Ridge along Indian Wells Drive is on Northern Douglas County Water and Sanitation District. Southgate reminds owners that they own the buried water service lines and sewer laterals serving their property.
What to do right now
- Close the main valve inside the house.
- Call your district for street-side trouble. West of I-25, Southgate answers at 303-779-0261. East of I-25 or in Terra Ridge, use the number on your water bill.
- Shut down a leaking water heater by closing its cold supply and turning off gas or power.
- Stop using water if a drain is backing up.
- Leave if you smell gas and call 911 and Xcel Energy from outside.
- Take photos before moving things or starting cleanup.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Water stain spreading across a ceiling | Leaking supply line, valve or drain above |
| Basement floor drain overflowing | Blocked sewer lateral (owner's line) |
| Soft, wet patch in the front lawn | Leak in the buried service line |
| Water around the water heater base | Tank or fitting failure |
| Leak in a garage wall after a freeze | Frozen and split pipe or hose bib |
Cost factors
Night, weekend and holiday visits usually cost more than weekday work. Access is next: a leak behind a finished wall takes longer than one in an open utility room, and a buried service line leak may need digging. The size of the job matters too. Lone Tree requires permits for any work on plumbing, gas, mechanical or electrical systems, including replacements, and names new water heaters and in-home sewer line repairs as permit work. Clearing a stoppage or repairing a drain or supply leak typically does not need one. Applications go through the city's Accela portal, so the plumber can stop the immediate problem first and file for the lasting repair. When you call, have the address and your district name ready. No arrival time is promised.
