Septic system maintenance in Spokane Valley keeps your home safe, prevents costly repairs, and protects the local environment. Over one-third of homes in the area rely on septic systems instead of city sewers, making regular care essential for property value and health.
This guide explains how to inspect, maintain, and troubleshoot your septic system, helping you avoid backups, odors, and expensive emergencies year-round.
Why Septic System Maintenance Matters in Spokane Valley
Septic systems treat and dispose of household wastewater on-site. Without regular maintenance, solids can build up, clogs can form, and untreated waste may leak into the ground or back into your home.
In Spokane Valley, septic failures can contaminate the Spokane Valley-Rathdrum Prairie Aquifer, which supplies drinking water to over 500,000 people. Proper care helps prevent pollution and ensures your system lasts for decades.
How a Septic System Works in Spokane Valley Homes
A septic system includes a tank, drain field, and connecting pipes. Wastewater flows from your home into the tank, where solids settle and bacteria break down organic matter. Liquid effluent then moves to the drain field, where soil filters and treats it before it returns to the groundwater.
If you’re unsure about your system’s design, septic system installation experts can help you understand its components and layout.
Routine Septic System Maintenance Tasks
Inspect and Pump Regularly
- Inspect your septic tank every 1-3 years, or annually for systems with pumps or advanced features.
- Pump the tank every 3-5 years, or when sludge and scum reach critical levels.
- Keep maintenance records for all inspections and pumpings.
Septic tank service professionals can measure sludge and scum layers and recommend the right pumping schedule for your household size and tank capacity.
Watch for Warning Signs
- Slow drains, gurgling pipes, or sewage odors may signal a full or failing tank.
- Soggy ground, lush green grass, or standing water above the drain field often means a problem.
- Sewage backing up into toilets or sinks requires immediate action.
If you notice these signs, call an emergency plumber to prevent further damage.

What Not to Flush or Pour Down the Drain
- Only flush human waste and toilet paper.
- Never flush wipes, diapers, feminine products, or paper towels.
- Avoid pouring grease, oil, chemicals, or medications down the drain.
- Limit the use of garbage disposals, as food waste increases solids in the tank.
Proper disposal habits keep your septic system healthy and prevent clogs.
Protecting Your Septic Drain Field in Spokane Valley
The drain field is vital for treating wastewater. Protect it by:
- Keeping vehicles, heavy equipment, and livestock off the area.
- Planting only grass, not trees or shrubs, to prevent root intrusion.
- Diverting roof gutters and sump pump water away from the field.
- Avoiding excess water use, which can flood the field and cause failure.
For drain field repairs or upgrades, septic drain field service can restore proper function.
