Services
Our technicians are DEQ certified in both pumping and installation to correctly identify any issues with your system and appropriately advise the customer with a recommended solution. Our team of DEQ certified Technicians are trained to inspect all aspects of your septic system. You name it, we install it.
Our DEQ certified team can provide a comprehensive eight page inspection report for your entire Septic System. These reports are most commonly used in real estate transactions! The Oregon Department of Environmental Quality recommends having your septic system evaluated by a professional if you're buying or selling a home.
Our team of experienced technicians are fully licensed, bonded, insured and ready to help. All of our pumpers are also DEQ Certified in both Septic Inspection and Installation so you can be sure you are getting top notch service from qualified professionals. The first thing we tell anyone who is new to owning a septic tank, is to get their tank pumped every three to five years.
Our certified professionals are trained to diagnose a problem anywhere from the clean out to the drain field. This way all your septic needs can be addressed in one place. If you suspect that you need to have your drain lines cleared or inspected, feel free to give us a call and a certified professional can help you over the phone!
ATTs are placed after a septic tank to utilize more efficient aerobic bacteria in the wastewater by introducing aeration (and oxygen) to the treatment process before sending it to a drain field for final treatment and dispersal. For homes and businesses outside areas served by large sewer systems, sewage is treated and dispersed into the soil by septic systems.

We had Lil stinky install a new septic tank and less then a year it settled and 2 of our toilets overflowed. I called roto rooter and 5000.00 and 3 days later they solved the problem. Lil stinky came out and dug up our yard again and the over flow tube that turned 90 degrees. They said it wasn't there problem and I sent a letter to their registered agent for some kind of reimbursement with no response.

Richard came to the house today to pump our septic. He communicated well about his timeline for the day. When he arrived he was respectful of our property and our time. He answered all of my questions and did a great job. Definitely will be using Lil Stinky again!

Sunday morning we realized we had a septic problem. Lil’Stinky came in a very timely manner and helped us uncover our septic lid only to find we had a clogged intake. He loosened it, and we were flowing freely again. He answered all of our questions and said we didn’t need the tank pumped at this time which saved us a bundle. Their fee was definitely in line with a Sunday morning emergency call. I would highly recommend this company.

Wow, this was some of the best costumer service i have experienced in any field. I had a septic alarm going off, Cory pumped my tank and trouble shoot my issue and the price was the same as I paid to just pump my tank with a different Co. On top of that Cory spent the time on the phone to explain to me what was going on and couldn't have been nicer or more helpful. If you need septic service, believe the hype, look no further, call these guys!

Tim from Lil' Stinky was phenomenal! He went above and beyond. Was incredibly professional and was beyond helpful. He figured out a plumbing issue even the plumbers our home warranty company sent out couldn't resolve. He gave us great advice for preventing any further issues as well. Highly recommend this company, especially Tim!

Corey came out on the Saturday of Memorial Day weekend. He was very professional and knowledgeable. He was the third person to come look at our system and right away diagnosed the problem and fixed it. He was also very patient, taking time to talk to our home insurance company by phone to detail the service and help us get reimbursed. Unfortunately we have have had several local companies come out for this problem. Lil Stinky is the best by far!

Left a message for Lil’ Stinkey to get our septic tank cleaned and never received a call back. Ended up calling another company that called back in a couple hours and cleaned two days later.

Chad was a super friendly guy. He knows his business and shared helpful hints to keep my septic system healthy. I have used Lil' Stinky services multiple times now and have never had an issue. Priced cheaper than other companies I called, and still great service and quick response.
Definitely the ones to call!!

Lil Stinky gave us a much more reasonable estimate on our septic repair than anyone else. They came promptly did the work in a day had it inspected the next day and back filled at the same time. Their workers were friendly professional and very knowledgeable. They really helped us when we were in a time crunch and did an excellent job and I would highly recommend Lil Stinky over anyone else
