Septic System Installation & Repair FAQ for Spokane Homeowners

How often should Spokane homeowners get septic system installation & repair?
Given Spokane's semi-arid climate — drier than western washington with 17 inches of annual rainfall, most homeowners benefit from septic system installation & repair at least once a year. Snow removal from roofs and driveways (November–March) often makes spring or fall the optimal time to schedule service.
What home types in Spokane most need septic system installation & repair?
Craftsman bungalows in South Hill and South Manito neighborhoods and Victorian and Foursquare homes in Browne's Addition are the most common home types in Spokane and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How long does a septic system last?
A properly designed and maintained septic system lasts 25–30 years. Drain fields can last 25–50 years. Premature failure is usually caused by improper use (flushing non-biodegradables, using garbage disposals heavily) or lack of pumping.
How much does a new septic system cost?
A conventional gravity system typically costs $5,000–$15,000. Alternative systems (mound, aerobic, drip irrigation) cost $15,000–$30,000 or more due to site constraints and added complexity.
What causes a drain field to fail?
The most common causes: solids overflow from an unpumped tank clog the drain field, hydraulic overload from too much water, root intrusion, and physical damage. Failed drain fields usually cannot be rehabilitated and must be replaced.
Can I add a bathroom or bedroom to a house with a septic system?
Additions may require a system upgrade if the existing system isn't sized for the additional load. A septic evaluation is typically required for permits involving additions.
