Beginner's Guide to Drilling a Well | Spring Creek Drilling

What Is Well Drilling, Really?

At its simplest, drilling a well means boring a hole deep into the ground until you reach an aquifer — a layer of rock or sediment that holds groundwater. Once you tap into that aquifer, a pump brings the water up to the surface and into your home. That's it. No city water bills, no municipal treatment plant, and no dependence on someone else's infrastructure. Just your own private water supply, right on your property.

If that sounds appealing, you're not alone. Thousands of families across Eastern Washington rely on private wells every single day, and for good reason.

Why People in Eastern Washington Drill Wells

If you live in or around places like Spokane County, the Palouse, the Columbia Basin, or anywhere in the rural stretches between, you already know that municipal water service doesn't reach everywhere. Many properties out here — whether they're hobby farms near Cheney, new homesteads outside of Ritzville, or ranches in the Okanogan — simply don't have a city water line running to the lot.

Drilling a well solves that problem permanently. Instead of hauling water or negotiating with a distant water district, you get a reliable, independent water source that serves your household, your livestock, and your irrigation needs year-round. In a region where summers are hot and dry, that kind of independence matters.

Dug Wells vs. Drilled Wells

You may have heard of dug wells — the old-fashioned kind excavated by hand or with a backhoe, usually only 10 to 30 feet deep. While they still exist on some older Eastern Washington properties, they come with real drawbacks:

Shallow depth makes them vulnerable to seasonal water table drops, especially during our dry summers.
Contamination risk is higher because surface water, agricultural runoff, and bacteria can seep in more easily.
Lower yield means they may not keep up with household demand during peak use.

Drilled wells, on the other hand, typically reach 100 to 400 feet or more in Eastern Washington (depending on your location and geology). They access deeper, more protected aquifers, deliver more consistent flow rates, and are far less susceptible to contamination. For almost every situation out here, a drilled well is the better choice.

The Well Drilling Process, Step by Step

Drilling a well isn't something that happens overnight, but it's also not as complicated as you might think. Here's how the process typically unfolds when you work with a licensed driller in Washington State:

Initial site visit and consultation — A driller comes out to your property to evaluate the terrain, talk through your water needs, and discuss where the well should go. They'll consider setback distances from septic systems, property lines, and other structures. If available, they'll review well logs from neighboring properties to estimate depth.
Permits through Washington State — In Washington, well construction is regulated by the Department of Ecology. Your driller will help you navigate the permitting process, which includes filing a well construction notice before any work begins. This ensures your well meets state standards for safety and water rights.
Drilling day — The drill rig arrives and the crew gets to work. Depending on geology, they may drill through layers of topsoil, clay, basalt, and gravel before hitting the water-bearing formation. Most residential wells in Eastern Washington are completed in one to three days.
Casing and grouting — Steel or PVC casing is installed to line the borehole, and the space between the casing and the surrounding earth is sealed with grout. This prevents surface contaminants from reaching your water supply.
Well development and testing — After drilling, the well is "developed" — pumped and flushed to clear out fine sediment and maximize water flow. A yield test measures how many gallons per minute the well produces, so you know exactly what you're working with.
Pump installation — Once the well is drilled and tested, a separate pump professional installs a submersible pump, pressure tank, and connects everything to your home's plumbing. Your well driller can typically recommend a trusted pump installer in the area.

What to Expect on Drilling Day

Drilling day is exciting, but it's also loud and a little messy — and that's completely normal. Here's what you should know going in:

The rig is big. A drill rig is a large truck-mounted machine. Make sure there's a clear path to the drilling site, and keep vehicles, pets, and kids at a safe distance.
There will be noise. Drilling through Eastern Washington's basalt layers is not quiet work. Plan accordingly if you work from home or have close neighbors.
You'll see water and mud. As the drill bit cuts through rock, water and drilling fluid circulate to the surface. There will be muddy runoff around the drill site — this is normal and temporary.
Depth isn't guaranteed in advance. Geology varies even within the same neighborhood. Your driller will give you their best estimate based on area data, but the actual depth depends on where the aquifer sits beneath your specific property.

Most homeowners find it fascinating to watch. If you're curious, ask your driller if it's safe to observe from a reasonable distance — most are happy to explain what's happening as they go.

Cost Ballpark: What You Should Budget

Well drilling costs in Eastern Washington typically range from $5,000 to $25,000 or more, depending on several factors:

Depth — The deeper the well, the more it costs. Drilling through hard basalt is more expensive per foot than softer formations.
Pump and equipment — A submersible pump, pressure tank, wiring, and plumbing all add to the total.
Site access — Steep, remote, or heavily wooded properties may require extra preparation before the rig can get in.
Water treatment — If your water test shows elevated minerals, iron, or hardness (common in parts of Eastern Washington), you may want to add a treatment system.

A good driller will give you a transparent estimate before any work begins, and they'll explain what's included so there are no surprises.

Choosing a Driller: What to Look For

This is one of the most important decisions you'll make in the process. In Washington State, all well drillers must be licensed through the Department of Ecology. That license means they've demonstrated competency in well construction, understand state regulations, and are accountable to a professional standard.

Beyond licensing, look for a driller who:

Has experience working in your specific part of Eastern Washington (geology varies widely from the Palouse to the Okanogan).
Is willing to walk you through the process and answer your questions without rushing you.
Provides a written estimate that details the scope of work.
Has solid reviews or referrals from other property owners in the area.

Annual Maintenance: Protecting Your Investment

Once your well is in and running, it doesn't need a lot of attention — but it does need some. A simple annual maintenance routine will keep your system reliable for decades:

Test your water annually for bacteria (coliform) and nitrates. Your local health district can provide testing kits or recommend a certified lab.
Inspect the well cap and casing to make sure the seal is intact and no critters or debris have gotten in.
Check your pressure tank and pump performance. If you notice fluctuating pressure, sputtering faucets, or the pump cycling on and off frequently, call a professional before a small issue becomes a big one.
Keep records. Hold onto your well log, water test results, and any service records. They're valuable if you ever sell the property or need warranty work done.

Drilling a well is one of the smartest investments you can make on a rural Eastern Washington property. It gives you control over your water supply, adds real value to your land, and — when done right — serves your family reliably for generations. If you're just starting to think about it, you're already on the right track.
