First ten minutes: protect people and property
Sewage carries bacteria and should be treated as a health hazard. Stop running water in the house, including toilets, washers and dishwashers, because every gallon you send down adds to the backup. Keep children and pets out. Open windows if the smell is strong and turn off the HVAC fan if it spreads odor.
Wear rubber boots and gloves if you must enter the area. Move valuables off the floor, and take photos of the water level and affected items for your insurer. Do not use fans to dry the area until you know the water is clean, and do not mix cleaning chemicals.
What not to do
- Do not keep flushing or running water to see if it clears
- Do not pour chemical drain openers into a standing backup
- Do not open the outdoor cleanout cap unless a plumber tells you to
- Do not touch sewage with bare hands
- Do not ignore it, since sewage soaks drywall and flooring
- Do not use a wet vacuum on sewage unless it is rated for it
City main or your private line?
The answer decides who you call.
| What you see | Likely source | Who to call |
|---|---|---|
| Neighbors report backups too | City sewer main | City sewer standby, (760) 625-6781 |
| Only your home is affected | Private lateral | A plumber. See sewer line cleaning |
| Backup only in the lowest drain | Main line blockage | A plumber, promptly |
| One fixture only | Local clog | Try a plunger, then call |
| You are on septic | Full tank or failing drain field | A septic pumper and plumber |
How plumbers clear the line
A technician finds the cleanout and runs a cable machine to cut through paper, roots or soft blockages. Heavy grease or scale may need a high-pressure water jet. After clearing, a camera run shows whether the pipe has cracks, roots or sags that caused the backup.
If the camera finds damage, the next step is a repair plan. A cracked or collapsed pipe will clog again no matter how often it is cleaned. That is when sewer line repair stops the cycle.
Who handles what in Coachella
The City of Coachella Utilities Department operates the sanitary sewer and lists a sewer standby line for overflows. Its office is at 53462 Enterprise Way and is open Monday through Thursday. Outside those hours, the standby number is the way to reach the City about a main line problem. A private lateral from your house to the main is the owner's responsibility.
In Thermal and other east valley areas, many properties use septic systems. The Coachella Valley Water District has studied a sewer consolidation project for roughly 150 septic systems in east valley communities. If you are in one of those areas, tell the dispatcher you are on septic, since the response differs from a sewer backup.

Cleanup, insurance and health
Porous materials like carpet, padding and drywall that touched sewage usually cannot be saved. Hard surfaces can be disinfected. Many homeowners hire a restoration company for anything beyond a small spill. Wash hands thoroughly and wash clothing that touched sewage separately.
Check your homeowner's policy for a water backup endorsement. Without one, damage from sewer backup is often excluded. Photograph everything before cleanup, keep receipts and call your agent early. Ask the plumber for a written report of what failed and what was done.
Preventing the next backup
Keep grease, wipes and paper towels out of drains. Do not flush anything except toilet paper. Have a camera inspection if your line has backed up more than once, and consider a backwater valve if your home sits below the street. Know where your cleanout is and keep access clear.
If you have trees near the sewer path, roots may be involved. Cutting roots clears the line but does not repair the entry point. A plumber can show you on video where the roots get in and recommend a plan.
Warning signs before a backup
Backups rarely arrive without warning. Slow drains in several fixtures, gurgling when you run water, a sewage smell near a floor drain and water that rises in the tub when the washer drains are all signs the line is narrowing. Act on them within days, not months.
If you notice these signs after heavy rain or a long period of vacancy, mention it when you call. Roots grow toward moisture, and a vacant house with no flushing can let sediment settle and harden in the pipe. Each of these details helps the plumber pick the right tool.
Talking to your landlord or HOA
Renters should notify the landlord immediately and document the date and time. Owners in an HOA should ask whether the backup involves a shared line. In a condo or townhouse, a blocked main may serve several units, and the association decides who pays. Get the decision in writing.
If you are a landlord, respond quickly and keep records. Tenants who live with sewage face health risks, and delays can create liability. A fast response, a clear plumber's report and a clean-up plan protect everyone involved.
Common questions
Yes. Sewage is a health hazard and it spreads. Stop using water and call right away.
If several neighbors are affected, call the City Utilities sewer standby line at (760) 625-6781.
Often only with a water backup endorsement. Check your policy and call your agent.
Often one to two hours, longer if jetting or a camera follow-up is needed.
Not on a standing backup. It will not reach the blockage and it is dangerous to touch.
