Aerobic Septic Service in Centennial, CO

If your home in Centennial 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.

Why aerobic systems need air

The difference between an aerobic unit and a regular septic tank is oxygen. A small compressor pushes air into the treatment chamber around the clock, keeping oxygen-loving bacteria alive. If the air stops, those bacteria die off within days, odors build and poorly treated water reaches the yard, which is why a silent aerator is worth a call.

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.

Signs your aerobic system needs attention

Watch for a sewage or rotten egg smell, an aerator that is silent, cloudy or foul-smelling discharge, spray heads that do not run, and alarms. Soggy areas near the spray field can also point to a problem.

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.

Aerobic system components, from tank to yard

From the house outward, an aerobic system usually has a trash or pretreatment tank, an aeration chamber with a compressor, a clarifier, a disinfection unit and a pump tank that feeds spray heads or drip lines. A control panel ties it together and sounds the alarm when something stops working.

When to call right away

Call soon if the alarm sounds and does not stop after you check the breaker, or if the aerator is silent. A strong odor near the unit or the spray field is another reason to call. Treated water that looks gray or smells like sewage is a sign something needs attention in your Centennial system.

Aerobic units in Arapahoe County

Aerobic systems are common in parts of Arapahoe County where the soil cannot handle a conventional drain field. Because they rely on power, air and moving parts, they need regular attention from a company that services them. Homeowners in Centennial and nearby towns such as Greenwood Village, Lone Tree, Cherry Hills Village often keep a maintenance contract in place for that reason.

Why Centennial conditions matter for aerobic systems

Most mapped soils near Centennial 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 17 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 Centennial that affect aerobic septic service

Among the mapped soils within about two miles of central Centennial, the USDA soil survey rates 75% as very limited for septic absorption fields, 23% as somewhat limited and 2% 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.

Centennial averages about 17 inches of precipitation a year, and July is usually the wettest month. Average temperatures stay below freezing for about 3 months a year, with December averaging 28°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
