In many areas, yes, especially after the first years. Check with the Gasconade County health department to see what applies in Hermann.

Can a regular septic company service my aerobic unit?

Aerobic Septic Service in Hermann, MO

If your home in Hermann 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.

Inside an aerobic treatment unit

Most units have three stages: pretreatment, aeration and clarification, followed by disinfection and dispersal. The aerator runs much of the day, and an alarm warns of high water or equipment failure. Each part has to work for the system to treat water properly.

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.

Common aerobic system alarms

Alarms usually signal high water in a pump tank or a problem with the aerator. Causes include a failed compressor, a tripped breaker, a stuck float, a failed pump or more water entering than the system can handle. Silence the alarm, reduce water use and call for service rather than ignoring it.

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.

When to call for aerobic service

Call if the alarm keeps coming back or the compressor is hot, noisy or has stopped. Also call if you smell sewage near the unit or it has been more than a few months since the last service visit. Early service is usually far cheaper than repairs after a failure.

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.

The parts of an aerobic system in Hermann homes

Most aerobic units have an aerator or air compressor, a control panel with an alarm, one or more floats, and a disinfection unit that uses chlorine tablets or ultraviolet light. Many also have a pump that sends treated water to spray heads or drip lines. Each part wears on its own schedule. Aerators and pumps run many hours a day, so they are usually the first to need attention, while floats and alarms fail less often but matter just as much.

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 Hermann home for a long time, ask your service company whether the unit should keep running while you are gone.

Aerobic units in Gasconade County

Aerobic systems are common in parts of Gasconade 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 Hermann and nearby towns such as New Haven, Warrenton, Montgomery City often keep a maintenance contract in place for that reason.

Why Hermann conditions matter for aerobic systems

Most mapped soils near Hermann 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. Hermann averages about 43 inches of precipitation a year, and alarms tend to come more often in May. About 1 months below freezing make a sheltered, working aerator important, since treatment slows when the unit gets too cold.

Local conditions in Hermann that affect aerobic septic service

Among the mapped soils within about two miles of central Hermann, the USDA soil survey rates 97% as very limited for septic absorption fields, 3% as somewhat limited and 0% 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.

Hermann averages about 43 inches of precipitation a year, and May is usually the wettest month. Average temperatures stay below freezing for about 1 month a year, with January averaging 30°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
