Who We Serve
Property owners across Kootenai County building on raw land, planning an ADU or bedroom addition, or installing septic for the first time on a residential or rural property.
Problems We Solve
We design, permit, and install septic systems that meet current Idaho code, hold for 30+ years, and pass inspection cleanly when the property changes hands.
Kootenai County Is One of the Fastest-Growing Counties in Idaho, and Most of That Growth Requires a Septic Permit Before Anything Else Gets Approved
New custom homes in Coeur d’Alene, cabin rebuilds on Hayden Lake, ADU additions in Spirit Lake, shoreline projects on Bayview’s Lake Pend Oreille frontage — growth is happening across every corner of Kootenai County, and nearly all of it runs through a septic permit before a building permit moves forward. Quality has to start from the ground up. Whether you’re installing on a flat valley lot, a steep hillside parcel, or a lakefront property on Lake Coeur d’Alene or Hayden Lake, we handle the design, the permits, and the installation.

You Probably Recognize One of These
Most septic installation calls across Kootenai County fall into one of these situations. If yours does, we’ve handled it before.
You’re Building a Custom Home and Need Septic Installed
The plans are drawn and the permits are in motion. You need a licensed installer who can put the septic system in on schedule so your foundation and framing crews aren’t waiting on an open site.
You Bought Raw Land in Kootenai County and Have Never Dealt With Septic
You’re building from scratch on a rural or semi-rural Kootenai County lot; maybe a hillside parcel near one of the lakes, maybe an inland property outside the city limits, and you’ve always been on city sewer. You need someone who can walk the property, explain what the lot actually requires, and handle the full installation as a single package.
You’re Planning an ADU or Adding a Bedroom
You’re finishing a basement, building a detached guest unit, or converting a space to short-term rental somewhere in Kootenai County, and someone just told you the existing septic won’t cover it. Call us before you finalize the plans. We’ll save you a denied permit and a scheduling delay.
You’re Buying a Property and There’s No Septic Yet
You’re closing on a Kootenai County lot and the previous use didn’t include a permitted septic system. You need a clean starting point designed and installed to current Idaho code before the build can begin.
You’re Building on a Lakefront Lot
Your property sits on Lake Coeur d’Alene, Hayden Lake, Spirit Lake, or the Bayview shoreline on Lake Pend Oreille, and the standard septic playbook doesn’t apply. Shoreline setbacks, aquifer protection requirements, and engineered drainfield standards all shape what’s permitted. You need someone licensed for the complex designs and permit work these properties require.
Your Builder Needs a Reliable Septic Sub Across the County
You’re a custom home builder working across Kootenai County and you need a septic installer who shows up on schedule, coordinates with the build timeline, and doesn’t leave your concrete crew waiting. We’ve worked behind enough builders to know what makes their job easier.
Working Across Kootenai County
We’re based in Athol and handle septic system installation projects throughout Kootenai County, including Coeur d’Alene, Hayden, Hayden Lake, Post Falls, Spirit Lake, Bayview, and the rural parcels between them. For properties outside our usual coverage area, give us a call and we’ll talk through it.
Do I need a septic system if I’m building in Kootenai County?
It depends on whether your lot is served by city or municipal sewer. Much of Kootenai County, including rural parcels, hillside lots, and properties near the lakes, requires private septic. Panhandle Health District determines what’s required during the permitting process. If you’re unsure, call us before you finalize the purchase or the plans.
How long does a new septic installation take in Kootenai County?
Most standard new installations take a week or less from permit approval to backfilled and operational. Engineered systems and lakefront installs on Lake Coeur d’Alene, Hayden Lake, or Lake Pend Oreille can take longer when soil conditions, aquifer setbacks, or engineered drainfield designs are involved. You’ll get a clear timeline in the written quote.
Who handles the permits for a Kootenai County septic installation?
We do. Every new septic installation in Kootenai County requires a permit through Panhandle Health District. We manage the full process; site evaluation, system design submission, and inspection coordination. You don’t file anything yourself.
Why do lakefront properties in Kootenai County require a different septic process?
Properties on or near Lake Coeur d’Alene, Hayden Lake, Spirit Lake, and the Bayview shoreline on Lake Pend Oreille, as well as lots over the Spokane Valley-Rathdrum Prairie Aquifer, face additional regulatory requirements. These include engineered drainfield designs, tighter shoreline setbacks, and nutrient-pathogen evaluations. We hold the complex installer license required for this work.
Does adding a bedroom or ADU in Kootenai County require a new septic system?
Almost always. Idaho calculates septic capacity by bedroom count, and adding a bedroom, finishing a basement room, or building an ADU almost always triggers an upgrade or new system requirement. Call us before you finalize your plans. We’ll save you the trouble of a denied building permit.
Do you also pump septic tanks after installation?
We don’t pump, but we work closely with Little Stinker, a long-trusted septic pumping service in North Idaho. We refer all our Kootenai County clients to them for ongoing pumping and routine maintenance, and they refer their installation work to us. You’re in good hands either way.
