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.

What chlorine does an aerobic system use?

Most use chlorine tablets made for wastewater treatment, not pool tablets. Ask your service company which product your unit requires.

Is a service contract required?

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

Can a regular septic company service my aerobic unit?

Many can, but not all. Ask whether the company works on aerobic systems and on your brand.

Aerobic Septic Service in Richland, WA

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 Benton 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 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.

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.

Choosing an aerobic service provider

Look for a company familiar with the aerobic units common around Richland and West Richland, Kennewick, Pasco, clear service records and responsive alarm calls. Ask for references if you are signing a multi-year contract.

What wears out first

In aerobic systems around Richland, the aerator and the pump do the most work, so they tend to wear out first. Diffusers can clog with scale, floats can stick, and spray heads can fill with grit or get knocked out of position by mowers. Chlorine tablets run out on a regular cycle. A service visit that checks each of these in order is the easiest way to avoid a surprise failure.

Simple checks for Richland homeowners

Between professional visits, take a minute each week to listen for the aerator hum, glance at the alarm light and make sure the spray heads are not clogged with grass. Keep chlorine tablets stocked if your unit uses them, never block the compressor vents, and write down anything unusual to tell your technician.

Keeping an aerobic unit running in Richland

An aerobic system in Richland works best when power stays on and the air pump never sits idle. If the alarm sounds, cut back on water and call for service instead of silencing it. Chlorine or other disinfectant tablets need regular refills where the system uses them. A technician can show you what to check between visits.

Why Richland conditions matter for aerobic systems

Most mapped soils near Richland 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 10 inches of precipitation a year, spray and drip fields here depend on steady treatment rather than rain to disperse water.

Local conditions in Richland that affect aerobic septic service

Among the mapped soils within about two miles of central Richland, the USDA soil survey rates 64% as very limited for septic absorption fields, 16% as somewhat limited and 20% as not limited. The most common drainage class is 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.

Richland averages about 10 inches of precipitation a year, and December is usually the wettest month. December is the coldest month at about 33°F on average, so freezing is rarely the main concern here. Heavy rain and saturated ground are the bigger factors for drain fields.

What the soil around Richland means for aerobic septic service

By drainage class, the USDA soil survey maps the land around Richland as 39% excessively drained, 37% well drained, 13% somewhat excessively drained, 8% poorly drained, 4% somewhat poorly drained.
