Frequently Asked Questions

Can 509 Excavation install a septic system on a new construction project in Cheney?
Yes, their combination of general contracting and excavation services makes them well-suited for new septic installations as part of a broader construction project. They can typically handle permitting, site prep, and system installation without requiring a separate subcontractor for the excavation portion.
What's the typical cost range for a new septic system installation in Spokane County?
New system costs vary significantly based on system type, soil conditions, lot access, and current material prices, but homeowners in eastern Washington generally budget anywhere from $8,000 to $25,000 or more for a complete installation. Getting at least two or three quotes is strongly recommended since pricing can vary quite a bit between contractors.
Does the city of Cheney have a municipal sewer system, or do most properties use septic?
Properties within Cheney's city limits are generally connected to the municipal sewer system, but rural parcels and properties outside the city boundary often rely on private septic systems. If you're purchasing property in the Cheney area, confirm whether it's on sewer or septic before closing, as the maintenance costs and responsibilities differ significantly.
How does excavation impact an existing septic system during a construction project?
Heavy equipment operating near a septic system can compact the soil over the drain field, damage distribution pipes, or shift the tank itself, all of which can lead to system failure. It's critical to mark your system components before any excavation begins on your property, and a good contractor will ask about system locations before moving equipment.
What's the difference between a conventional and a mound septic system?
A conventional system uses gravity to distribute effluent through a drain field buried below grade, while a mound system builds up a raised bed of sand and soil above grade when the natural soil doesn't perc well enough for a conventional design. Mound systems are more common on lots with high water tables, shallow bedrock, or dense soil, all of which appear in parts of Spokane County.
How long does a septic system typically last in eastern Washington?
A well-maintained septic system can last 25 to 40 years or more, with the drain field often being the first component to wear out due to soil saturation and biomat buildup over time. Regular pumping every 3 to 5 years and avoiding heavy chemical use are the two most effective ways to extend system life.
