Is sewage in the house dangerous?

Sewage can carry bacteria and viruses. Keep people and pets away, wear gloves if you must touch anything, and clean affected areas thoroughly after the problem is fixed. Large spills may call for a professional cleanup company.

Will pumping the tank fix a backup?

Often it gets the house draining again, but it may not fix the cause. If the drain field or a pump has failed, the tank will refill and the problem will return, so ask for a diagnosis along with the pumping.

Should I call a plumber or a septic company?

If only one fixture is slow, a plumber may clear the clog. If several drains are slow or backing up, or there is an alarm or odor near the tank, call a septic company.

Does fixing a septic emergency need a permit?

Pumping and small repairs usually do not. Larger repairs and drain field or tank replacement often do. Check with the Harris County health department, or ask the septic company to handle permits for you.

Septic Backup or Alarm in Houston? Get Help Fast

Septic emergencies usually show up as a backup in the lowest drain, a sewage smell that will not go away or a high water alarm. Each of these means wastewater has nowhere to go, and it will only get worse with more water use.

Use the form or call to reach a local septic company working in Houston. Tell them what you are seeing so they can bring the right equipment on the first trip.

Keep the problem from getting worse

The fastest way to limit damage is to stop sending water into the system. Ask everyone in the house to hold off on showers, flushing and laundry. If wastewater is surfacing outdoors, keep the area clear. If the power went out and you have a pump system, the chamber may simply have filled while the pump was off. Limit water use until power returns and the pump catches up, and call if the alarm keeps sounding.

Common causes of septic emergencies

A tank that is overdue for pumping is the most common cause. Other frequent culprits include a clogged line between the house and the tank or a blocked outlet baffle or filter. A failed pump or a drain field that can no longer absorb water can also cause a sudden backup. Heavy rain can make a struggling drain field fail suddenly. Tree roots, crushed pipes and items like wipes or grease also cause blockages.

When the septic alarm sounds

A high water alarm means water in the pump tank or aerobic unit has risen above normal. Press the silence button, cut back on water and check whether the breaker for the pump has tripped. If the alarm comes back on or the breaker trips again, call for service, because the pump may have failed.

What the septic company will do

Expect the crew to ask questions first, then locate the tank and check the water level. If the tank is full, they will pump it so the house can drain. With the tank open, they can see whether the outlet, filter or baffles are blocked, and whether water is flowing back from the drain field, which points to a field problem. For pump systems they will test the pump, float and panel. You should get a clear explanation of the cause and your options.

Keeping your system out of trouble

Regular pumping and inspection are the best insurance against a surprise backup. Install risers so the tank is easy to reach, which makes service faster in an emergency. Fix leaking toilets and faucets, since constant trickles add up. Plant only grass over the drain field and keep trees at a distance. A maintenance plan from a local company can put all of this on a schedule.

What to ask an emergency septic company

Ask when they can be there and what the trip will cost, including any after-hours or weekend fee. Ask if they will pump the tank and look for the cause on the same visit, and whether they can handle a repair if one is needed. Confirm they serve your address before they head out.

While you wait for help in Houston

If sewage is backing up in a Houston home, stop using water right away. Do not run the washer, dishwasher or showers. Keep children and pets away from any wet area in the yard. Open windows for air if there is an odor indoors, and have the tank lid location ready for the crew.

Local conditions behind septic emergencies in Houston

Most mapped soils near Houston are rated very limited for septic absorption, so a drain field that is already working hard can back up quickly when something else goes wrong. About 49 inches of precipitation a year means saturated ground is common, and backups often follow long stretches of rain.

Local conditions in Houston that affect emergency septic service

Among the mapped soils within about two miles of central Houston, the USDA soil survey rates 80% as very limited for septic absorption fields, 0% as somewhat limited and 20% as not limited. The most common drainage class is somewhat poorly drained. Soils like these often call for careful system design, such as a larger drain field, a mound or another engineered system, and a site evaluation before any new installation or replacement.

Houston averages about 49 inches of precipitation a year, and June is usually the wettest month. January is the coldest month at about 50°F on average, so freezing is rarely the main concern here. Heavy rain and saturated ground are the bigger factors for drain fields.

What the soil around Houston means for emergency septic service

By drainage class, the USDA soil survey maps the land around Houston as 57% somewhat poorly drained, 29% poorly drained, 15% moderately well drained. Backups and wet spots are most common after heavy rain, and with 86% of the soil poorly drained the ground here can stay saturated for days, so it helps to know where your tank lid and cleanout are before you need them.
