Sewer service in Lone Tree depends on which side of I-25 you live on: Southgate Sanitation District to the west and Parker Water and Sanitation District to the east, with part of Terra Ridge on Northern Douglas County Water and Sanitation. A camera inspection of your private lateral shows roots, settling, separated joints or debris before any digging. Call the number on this page to be connected with a local plumber in Lone Tree.
Lone Tree is a planned, newer suburban city at the I-25 and C-470 junction, built around Park Meadows and the RidgeGate community, with grassland bluffs to the south. Most homes are relatively recent, so camera findings lean toward settled sections, shifted joints and construction debris rather than deteriorated pipe. The provider split is clear on the city's utility page: Southgate west of I-25, Parker Water and Sanitation east of it, and Northern Douglas County Water and Sanitation for some homes in Terra Ridge along Indian Wells Drive. Southgate reminds owners that they own the buried sewer laterals serving their property, and its line for water breaks and sewer backups is 303-779-0261.
What to do now
- Ease off the water. Pause laundry, the dishwasher and showers.
- Check which drains are affected. Several at once means the lateral is the likely problem.
- Know your district. West of I-25 is usually Southgate; east is usually Parker Water and Sanitation.
- Call the district if neighbors are affected. That suggests the main, not your line.
- Find the cleanout. It speeds up clearing and filming.
- Get the footage. A recording and marked location make repair decisions easier.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Lower-level drain backs up during laundry | Blockage in the lateral |
| Slow drains in a newer home | Settled section or construction debris |
| Toilet gurgles after a sink drains | Partial restriction downstream |
| Wet strip in the lawn over the line | Separated joint or crack |
| Clogs returning after clearing | Belly holding solids or roots at a joint |
Cost factors
- Cleanout access versus entry through a toilet
- Clearing the line first if it is full
- Length of the run to the district main
- Surface locating and saving the video
- Permits for repairs: Lone Tree lists sewer line repairs within the home as permit work, applied for online through Accela (Building Division 720-390-5211); clearing a stoppage typically does not need one
The number on this page connects you with an independent local plumber who serves Lone Tree. Mention whether you are east or west of I-25, which drains are affected and roughly when the house was built. In RidgeGate and other newer areas, a builder warranty may still apply, so keep the footage either way.
