Aerobic System Maintenance for Steilacoom Homes
Aerobic systems need more attention than conventional septic tanks. Many areas require regular inspections or a maintenance contract to keep them working and in compliance.
Companies that work across Pierce County can set up a service schedule and respond when an alarm goes off.
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 routine service includes
A typical service visit checks the aerator and air lines and inspects the control panel and alarm. The technician also looks at the water in each chamber, tests or refills the chlorinator, checks spray heads or dispersal parts, and measures sludge levels. The technician should leave a written record of what they checked and found.
When your aerobic alarm goes off
First check the breaker for the system. If it has tripped and trips again after resetting, do not keep resetting it. Cut back on water use and schedule service. Tell the company the brand of your unit if you can find it, since parts differ between manufacturers.
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.
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.
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 Steilacoom unit has helps you understand a service quote.
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 Steilacoom system.
Aerobic units in Pierce County
Aerobic systems are common in parts of Pierce 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 Steilacoom and nearby towns such as Lakewood, University Place, DuPont often keep a maintenance contract in place for that reason.
Why Steilacoom conditions matter for aerobic systems
Most mapped soils near Steilacoom 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. About 60 inches of precipitation a year can overload spray fields and let water into tanks, so keep an eye on alarms after storms.
Local conditions in Steilacoom that affect aerobic septic service
Among the mapped soils within about two miles of central Steilacoom, the USDA soil survey rates 100% as very limited for septic absorption fields, 0% as somewhat limited and 0% as not limited. The most common drainage class is somewhat excessively 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.
Steilacoom averages about 60 inches of precipitation a year, and November is usually the wettest month. December is the coldest month at about 36°F on average, so freezing is rarely the main concern here. Heavy rain and saturated ground are the bigger factors for drain fields.
