Every septic job, big or small.
Fully licensed and certified for any job, however big, small or complex. Overcoming obstacles and designing solutions is what we do.
-
01
DEQ certified inspections
For real-estate transactions and peace of mind. We know the local regulations and what a buyer, seller or lender needs to see.
-
02
Septic & ATT installs
Conventional systems and alternative treatment technology, designed around your site and built correctly the first time.
-
03
Tank locates & drainfield mapping
Can't find the lid? We locate the tank and map the drainfield, so you know exactly what's under your yard.
-
04
Excavation & tank repairs
Tank repairs, line repairs and upgrades, backed by years of heavy-equipment work.
-
05
Troubleshooting & emergencies
Pump and float replacements, alarm calls and control panels. If something's beeping, call.

06
Maintenance contracts
State-required maintenance contracts and ATT servicing, kept on schedule so you don't have to think about it.

Warning signs
Your tank will tell you. Usually quietly.
-
Every drain is slow at once
One slow sink is a clog. The whole house is the system.
-
Gurgling in the pipes
Air being pushed back up the line has nowhere else to go.
-
A smell out in the yard
Especially near the tank lid or over the drainfield.
-
Grass greener over the drainfield
Or wet, spongy ground when it hasn't rained.
-
The alarm is going off
On a pump or ATT system, that's the system asking for help. Don't just silence it.
-
Backups in the lowest drain
A basement shower or floor drain usually shows it first.
How it works
One call. One contractor. No runaround.
Not all situations are the same, so the answer shouldn't be either. Here's how a job goes.
-
You call Kyle
Call or text 458-215-0075. You speak directly with the contractor who'll be doing the work, not an office.
-
We find what's actually wrong
Locate it, open it up, look properly. You get options for the issue at hand and enough information to make the call yourself.
-
Done right, start to finish
The same person from the first call to the final cover. That's what owner-operated means, and it's why the scheduling is simpler.
Licensing

FAQ
Questions people ask Kyle most.
Anything else, call or text. You'll get a straight answer.
Lane, Linn, Benton, Marion and Douglas counties, from our base in Cottage Grove. If you're near the edge of that, call and ask.
Alternative Treatment Technology: a system that treats wastewater further than a standard tank before it reaches the drainfield. Some sites in Oregon need one, and they need regular servicing under a maintenance contract, which we offer.
Buyers and lenders often ask for one, and it's far better to know about a problem before closing than after. We do DEQ certified inspections and know how real-estate transactions work.
Yes. Military, law enforcement, first responder and senior discounts are all offered. Mention it when you call.
Wipes (including the ones labelled flushable), grease and cooking oil, paper towels, medications, paint and solvents, and large amounts of bleach. The system relies on bacteria to do its job, and all of these get in the way.
