Aerobic Septic Service in Boulder, CO

If your home in Boulder has an aerobic septic system, it depends on an aerator, controls and often a disinfection step to work correctly. When any of those fail, the system can smell, alarm or discharge poorly treated water.

Request a call and a local company that knows aerobic units can inspect and service yours.

How an aerobic system works

Wastewater first settles in a pretreatment tank. It then flows to an aeration chamber where a compressor or blower adds air, helping bacteria break down waste far more completely than in a standard tank. A clarifier lets remaining solids settle, and many systems add chlorine or another disinfection step before the treated water is sprayed or dispersed.

Maintenance visits explained

Expect the technician to confirm the aerator is running, clean filters and diffusers as needed, check floats and pumps, and inspect the disinfection unit. They will note when the pretreatment tank needs pumping. Many areas require these visits to be reported, so keep your records.

What an aerobic alarm is telling you

Most aerobic alarms mean one of two things: water is rising too high in the pump chamber, or the aerator has lost air pressure. A tripped breaker, a failed compressor, a float stuck in the wrong position or a pump that no longer runs are the usual causes. Cut back on water and call for service rather than ignoring the light.

A service schedule for aerobic units

Aerobic units are not set and forget systems. Many permits and maintenance contracts call for a visit every four to six months, plus pumping of the pretreatment tank every few years. Households that run a lot of laundry or have many people may need visits more often to keep the unit treating water properly.

Warning signs from an aerobic system

Pay attention if the unit goes quiet, if the discharge looks cloudy or gray instead of clear, or if you smell sewage near the unit or the spray area. Wet spots that do not dry out, spray heads that never seem to run and an alarm that keeps coming back all point to a problem that a technician should look at soon.

Questions to ask an aerobic service company

Ask whether they service your brand of unit, what each visit includes, how they handle required reporting and how quickly they respond to alarms. Ask whether parts and chlorine are included in a service plan.

Parts that wear out on an aerobic unit

The parts that need replacing most often are the air compressor, its intake filter, the diffusers that release air into the tank, and the floats that switch the pumps. Spray heads clog, timers fail and chlorine feeders run dry. Knowing which parts your Boulder unit has helps you understand a service quote.

Simple habits that help

Spread laundry through the week, fix running toilets quickly and keep grease out of the kitchen drain. These habits keep the load on the system steady. If you will be away from your Boulder home for a long time, ask your service company whether the unit should keep running while you are gone.

Why Boulder conditions matter for aerobic systems

Most mapped soils near Boulder are rated very limited for septic absorption, which is one reason aerobic units are used here. The cleaner water they produce is easier on difficult soil, as long as the unit is serviced. With about 18 inches of precipitation a year, spray and drip fields here depend on steady treatment rather than rain to disperse water. About 3 months below freezing make a sheltered, working aerator important, since treatment slows when the unit gets too cold.

Local conditions in Boulder that affect aerobic septic service

Among the mapped soils within about two miles of central Boulder, the USDA soil survey rates 93% as very limited for septic absorption fields, 1% as somewhat limited and 6% as not limited. The most common drainage class is well 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.

Boulder averages about 18 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with December averaging 30°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.

What the soil around Boulder means for aerobic septic service

Aerobic Septic Service questions in Boulder

Do aerobic systems need to be pumped?
Yes. The pretreatment tank and sometimes other chambers still collect solids and need periodic pumping, usually less often than a conventional tank.
Can I turn off my aerator to save power?
No. Without air, the bacteria that treat the water die off, and the system can smell and discharge poorly treated water.
Is a service contract required?
In many areas, yes, especially after the first years. Check with the Boulder County health department to see what applies in Boulder.
Is SepticTank.com the company that services my system?
No. SepticTank.com connects you with an independent local septic company that serves Boulder. That company performs the service and sets its prices.
