Taking care of a septic system in Washington

A septic system works quietly until something goes wrong, so a little routine care goes a long way. Pump the tank every few years, keep a record of each visit, and spread out heavy water use like laundry. Keep grease, wipes and harsh chemicals out of the drains. Outside, keep vehicles and new structures off the tank and drain field, and point gutters and sump pumps away from the field.

Signs your system needs attention

Septic problems tend to show up gradually. Listen for gurgling pipes, watch for slow drains in more than one fixture, and check the yard for standing water or a sewer smell after heavy water use. If an alarm sounds on a pump or aerobic system, cut back on water and call for service rather than silencing it and waiting.

What to expect from a good Washington septic company

A reliable septic company serving Washington arrives when scheduled, locates and opens the tank without damaging the yard, and checks the inlet, outlet and filter as part of pumping. They tell you the sludge level and when to book the next visit. You should leave the appointment knowing the condition of your system.

Septic permits and rules around Washington

Septic permits near Washington are handled at the county or state level rather than by the city. Repairs, replacements and new installations usually need a permit and an inspection. Your septic company can pull the permit for you. If you are buying or selling a home, ask whether a septic inspection is required at closing.

Local conditions in Washington

Among the mapped soils within about two miles of central Washington, 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 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.

Washington averages about 45 inches of precipitation a year, and June is usually the wettest month. January is the coldest month at about 32°F on average, so freezing is rarely the main concern here. Heavy rain and saturated ground are the bigger factors for drain fields.
