Aerobic Septic Service in Durango, CO
Aerobic treatment units clean wastewater with oxygen and bacteria before it leaves the system. They work well on lots where a conventional drain field would struggle, but they have moving parts that need regular service.
A septic company that services aerobic systems in Durango and Bayfield can handle routine maintenance, alarms and repairs.
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.
What a maintenance visit looks like
On a maintenance visit the technician listens to and checks the aerator, clears the air lines and diffusers, tests the alarm and timer, and looks at the color and clarity of the water in each chamber. They measure sludge, top off or check the disinfection unit, and leave a written record of what they found and fixed.
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.
What to ask before signing a service contract
Before you sign, ask how many visits a year are included, whether parts and chlorine are covered, and how fast they respond to an alarm. Ask if they file any inspection reports your county requires on your behalf, and whether they are certified to work on your brand of aerobic unit.
The parts of an aerobic system in Durango 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.
What homeowners in Durango can do between visits
Check that the aerator is running when you walk past the unit, and listen for unusual noise. Keep the area around the unit clear so air can move freely. Top off chlorine tablets if your system uses them and you have been shown how. Avoid bleach, drain cleaners and large amounts of antibacterial soap, which can weaken the bacteria that do the treatment.
Who services aerobic systems near Durango
Not every septic company works on aerobic units, so ask before you book. Companies serving Durango and Bayfield that do this work can usually handle routine maintenance, alarm calls and pumping of the pretreatment tank in one relationship, which keeps the records for your system in one place.
Why Durango conditions matter for aerobic systems
Most mapped soils near Durango 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 20 inches of precipitation a year, spray and drip fields here depend on steady treatment rather than rain to disperse water. About 5 months below freezing make a sheltered, working aerator important, since treatment slows when the unit gets too cold.
Local conditions in Durango that affect aerobic septic service
Among the mapped soils within about two miles of central Durango, the USDA soil survey rates 81% as very limited for septic absorption fields, 19% 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.
Durango averages about 20 inches of precipitation a year, and September is usually the wettest month. Average temperatures stay below freezing for about 5 months a year, with January averaging 20°F, so tank lids and shallow lines benefit from a layer of snow or mulch rather than being cleared bare.
