New Well Drilling for Spokane-Area Homes and Rural Properties
A new water well generally falls into one of three categories, and knowing which one applies changes what a contractor needs to plan for before a rig ever shows up. A brand-new well on undeveloped rural land, often paired with new home construction, usually means no existing well log to reference and a site evaluation done from scratch. A replacement well becomes necessary when an aging well's yield drops for good, its casing fails, or contamination reaches a shallow well beyond what treatment can reasonably fix. A supplemental well gets added alongside an existing one when a property's water demand outgrows what a single well can reliably supply, common on larger rural parcels with irrigation or livestock needs. Each situation calls for a different starting point, but all three route through the same permitting and construction sequence described below.
How Well Drilling Works, Start to Finish
Drilling a compliant well in Washington follows a consistent sequence, whether the property is a quarter acre in Spokane Valley or forty acres near Deer Park.
Site evaluation
A contractor walks the property, checks any nearby well logs on file with Washington Ecology, and picks a location that meets required setbacks from septic systems, property lines, and existing wells.
Filing the Notice of Intent
At least 72 hours before drilling starts, the state well construction fee gets paid and a Notice of Intent is filed with Washington Ecology under WAC 173-160-151, covering location, proposed use, and contractor registration.
Matching method to geology
Spokane County's geology ranges from glacial gravel to hard basalt, and the drilling method, along with expected depth, gets adjusted once the driller sees what the ground actually holds.
Casing
Steel casing gets set to seal off shallow groundwater and keep surface contamination from ever reaching the aquifer the finished well actually draws from.
Pump installation
Once the hole reaches a productive depth, a submersible pump, pressure tank, and basic electrical hookup turn it into a working household water system.
Filing the well report
The contractor files a well report, also called a well log, with Washington Ecology, creating the public construction record a future owner can look up in the Well Report Viewer.
Why Well Depth and Cost Vary Across Spokane County
Well depth across Spokane County depends far more on geology than on any fixed rule. Properties near the Spokane Valley-Rathdrum Prairie Aquifer often hit water in glacial gravel under 100 feet down, while wells drilled into basalt rock outside the valley floor commonly run several hundred feet. Since drilling is billed by the foot, that difference in depth is the single biggest driver of total project cost. See the full cost guide for a per-foot breakdown by geology type and a reconciled range for a complete well system.
Do You Need a Permit to Drill a Well in Washington
Most single-family wells in Spokane County qualify for Washington's permit-exempt groundwater exemption, meaning no separate water right permit is required as long as use stays under 5,000 gallons a day. Every well still needs a Notice of Intent filed with Ecology and a construction fee paid before drilling starts, and a handful of Spokane County watersheds carry additional streamflow rules worth understanding before a project begins. See the permit-exempt wells page for the full breakdown by watershed.
Licensed, Insured Water Well Contractors
Washington's Water Well Construction Act requires anyone who contracts to construct a well to hold a license issued by Washington Ecology, with a narrow exemption for property owners drilling on their own land for personal use. Spokane Well Drilling Co. does not hold that license itself and does not perform the drilling directly; it is a locally operated service brand that routes requests to independent, Ecology-licensed and insured local well and pump contractors. Ask any contractor connected through this site for their current license and registration status directly before work begins.
Well Drilling Across Spokane County
Requests get routed to contractors covering Spokane, Spokane Valley, and the surrounding rural county, from North County communities like Deer Park and Chattaroy to West Plains towns like Cheney and Medical Lake. Rural properties often present different geology and site-access considerations than an in-city lot. See the full service area breakdown for coverage specific to your community, or submit a request and a local contractor will confirm coverage.

Well Drilling Questions, Answered Straight
How much does it cost to drill a well in Spokane?
Most Spokane-area residential wells cost between 10,000 and 20,000 dollars for drilling, casing, a pump, and a pressure tank, with deeper or hard-rock basalt wells running higher. Cost depends mainly on depth and geology. See the full cost guide for a per-foot breakdown and sourced ranges.
Do I need a permit to drill a well in Washington state?
Most homeowners do not need a separate water right permit for a single-family well using under 5,000 gallons a day, but every well still requires a Notice of Intent filed with Washington Ecology at least 72 hours before drilling, plus a state well construction fee. See our permit-exempt wells page for the full breakdown.
How deep do wells need to be drilled in Spokane County?
Well depth in Spokane County varies widely by geology, from wells under 100 feet in glacial gravel near the Spokane Valley-Rathdrum Prairie Aquifer to several hundred feet in basalt rock further from the valley floor. A licensed driller determines depth using local well logs and site conditions, not a fixed rule.
What is the average lifespan of a water well?
A properly constructed well can supply water for 30 to 50 years or longer, though the pump, pressure tank, and other mechanical parts typically need replacement well before the well itself does. Water quality, sediment, and gradually dropping yield are common signs a well is nearing the end of its service life.
Can I drill my own well in Washington state?
Washington law exempts an owner drilling on their own land for a farm or single-family home from needing a driller license, but the well still must meet state construction standards, and the owner must still file a Notice of Intent and pay the required fee. Most owners hire a licensed contractor instead.
