The tank is simply full
Maricopa County's pump-now levels are a scum layer within 3 inches or a sludge layer within 8 inches of the outlet. A tank past those levels needs every compartment pumped, then a regular schedule.
24/7 emergency service for backups, overflows, and alarms
24/7 Emergency Septic Service and Pumping in the Phoenix Valley
Emergency septic service is available 24/7, including nights, weekends, and holidays, and same-day emergency service is available. When sewage backs up, wastewater surfaces in the yard, or a pump fails, we pump out the tank when that is the right first step and look for what caused the problem, so you are not left with an empty tank and the same failure.
Watch for these signs
When to call for emergency septic pumping
- Sewage is backing up inside
- Wastewater is surfacing outside
- A high-water or pump alarm is sounding
- Odors and slow drains have worsened quickly
- The property cannot safely continue normal water use

Your options
Pump-out, repair, or both?
An emergency pump-out buys time. Whether it fixes the problem depends on why the tank backed up.
A pump, float, or control failed
On a system that moves effluent with a pump, emptying the tank only resets the clock. The level climbs again until the failed pump, float, or control is repaired.
A line or the drain field is the cause
A blocked inlet line, a broken baffle, or a drain field that no longer takes water can back up a tank that was pumped recently. Those need repair planning, and replacing a failed tank or field needs a county permit.
Around the Valley
When sewage reaches the house
The EPA advises avoiding contact with sewage that backs up into a home, because it may contain harmful pathogens, and contacting your local health department or regulatory agency for guidance. In most of the Phoenix Valley that agency is Maricopa County Environmental Services.
Planning the work
What affects the price
- How many compartments need pumping and how full they are
- Whether the lids are buried and have to be located and uncovered
- Hose distance from where the truck can park to the tank
- Whether a pump, float, or control also needs repair
- Records or an as-built drawing that show where the tank is
First steps for a backup, an overflow, or an alarm
What to do before help arrives depends on what the system is doing. In every case, cut water use to the minimum and call; emergency septic service is available 24/7.
- Sewage backing up inside: stop all water use, including a washing machine or dishwasher running on a timer, and keep people and pets out of the area. Do not pour chemical drain openers into a backed-up drain; Maricopa County warns that corrosive chemicals such as peroxide and sulfuric-acid products damage a septic system.
- Wastewater surfacing in the yard: keep people, pets, and vehicles off the wet area, and turn off irrigation that runs near the tank or the drain field. Maricopa County warns that driving over the disposal field damages it and that driving over the tank is dangerous unless its lid is reinforced.
- A high-water or pump alarm: cut water use to the minimum and leave the control panel and wiring alone. Silencing the alarm does not lower the level; the cause still has to be found.
- In every case, do not open the tank lids or reach into septic components yourself.
What to tell us when you call
A few details on the first call help us bring the right truck and equipment:
- What is happening and where: which fixtures are backing up, wastewater in the yard, or which alarm is showing.
- Whether the property is a home or a business, and for a business, what has to stay open and who will meet us on site.
- When the tank was last pumped, and whether the system has a pump, an alarm panel, or an aerobic treatment unit.
- Where the tank and lids are, if you know, and whether they are buried under soil, pavers, or turf.
- Gates, gate codes, animals, and how close a pump truck can park to the tank.
Septic emergencies at homes and at businesses
At a home, the first job is stopping water use and keeping the household away from sewage. Once the tank is pumped and the cause is found, you get a plan for the repair or for regular pumping so it does not happen again.
At a restaurant, hotel, apartment community, or HOA, a backup affects tenants, guests, and business hours. Maricopa County warns that large amounts of food, oil, and grease damage an onsite system, so a high-use tank that backs up may need a pumping schedule set by measured levels. After an emergency, our commercial septic maintenance page covers recurring programs. A backup at a wastewater lift station is One Call Plumbing's work.
Cleaning up after a sewage backup
The EPA's guidance for a home where sewage has backed up is specific. People doing the cleanup should wear protective clothing such as long rubber gloves and a face splash shield. Afterward, wash the equipment, tools, and clothing used, along with the flooded area, and disinfect everything exposed with a mix of 90 percent water and 10 percent household bleach.
Dry the area thoroughly and keep it out of use until it has been completely dry for at least 24 hours. Pumping the tank and repairing the cause stop more sewage from coming in; neither one cleans up what already came through the drain.

Common questions
Emergency septic questions
Is emergency septic service available at night and on weekends?
Yes. Emergency septic service is available 24/7, including nights, weekends, and holidays, and same-day emergency service is available. For a backup, overflow, or alarm happening now, call 480-640-1548 instead of waiting for a reply to the online form.
What should I do during a sewage backup?
Stop all water use, keep people and pets away from anything the sewage touched, and do not open the tank lids or reach into septic components yourself. Then call with what you know about the system, such as where the tank is and when it was last pumped.
Will an emergency pump-out solve the problem?
It may relieve the immediate condition, but the cause still needs to be identified. A failed pump, blockage, damaged component, or drain-field problem can cause the condition to return.
Is emergency septic pumping different from routine pumping?
The pumping is the same: the liquid, scum, and sludge come out of every compartment. The difference is the diagnosis that comes with it. On an emergency visit we also look for why the tank backed up, such as a failed pump, a blocked line, or a drain field that is not taking water.
Do you handle commercial septic emergencies?
Yes. Emergency septic service covers businesses, apartment communities, and HOAs as well as homes. Tell us what has to stay open, who will meet us on site, and where the tanks are, so the visit can be planned around tenants and customers.
Is it a septic emergency or a plumbing clog?
If one toilet or sink backs up while the rest of the building drains normally, the clog may be in that fixture's drain line. When several fixtures back up at once, the blockage is in the building drain or the septic system; sewage surfacing near the tank points to the septic system. Tell us which fixtures are affected when you call so we can tell which.
