Septic System Installation
New septic systems for rural lots, new construction, and properties replacing a failed system. We handle site evaluation, permits, tank installation, and drain field layout.
Drain Field Replacement
Failed or saturated drain fields are the most common septic problem in Benton County. We assess whether repair or full replacement is the right call — and give you a straight answer.
Septic System Repair
Cracked tanks, broken baffles, pump failures, distribution box issues — we diagnose and repair the full system, not just what's visible on the surface.
Sewer Line Repair & Replacement
Root intrusion, collapsed pipe, bellied lines — sewer line problems don't improve on their own. We repair sections or replace the full lateral, and we tell you which one you actually need.
Sewer Camera Inspection
Before recommending any sewer line work, we camera the line. You see exactly what's wrong — we're not guessing on your dime.
City Sewer Connection
Connecting off-septic to city sewer in Kennewick, Richland, or Pasco? We handle permits, lateral installation, septic decommissioning, and the final inspection sign-off.
Know the Warning Signs
How to Tell if Your Septic System is Failing.
Septic systems don't fail overnight — they give you signals first. Catching problems early is the difference between a repair and a full replacement. If you're seeing any of these, don't wait.
-
Slow or Gurgling Drains Throughout the Home
Not just one fixture — multiple slow drains at once point to a drain field or main line problem, not a simple clog.
-
Sewage Odors Inside or Outside
A properly functioning system is odor-free. Sulfur or sewage smells in your yard or near drains are a red flag.
-
Unusually Green or Soggy Grass Over the Drain Field
If one patch of your yard is noticeably greener or wet when the rest isn't, effluent is surfacing — a classic drain field failure sign.
-
Sewage Backing up into Toilets or Floor Drains
This is past warning-sign territory — your system is full or blocked. Call immediately.
-
Standing Water Near the Tank or Drain Field
Pooling water that doesn't drain, especially after normal household use, means the drain field can no longer absorb effluent.

Frequently Asked Questions
Answers to Common Septic & Sewer Questions.
These are the questions Tri-Cities homeowners ask us most about septic and sewer services. If you don't see yours, call — we'll talk you through it honestly before you make any decisions.
How much does a septic system installation cost?
A new septic system installation in the Tri-Cities area typically depends on system size, soil conditions, permit requirements, and whether a new drain field is part of the scope. Give us a call and we can give you an estimate.
How long does a septic system last?
A properly installed and maintained septic system typically lasts 25 to 40 years. Drain fields often have a shorter lifespan — around 20 to 30 years — depending on soil type, usage, and maintenance history. The single biggest factor in extending system life is regular pumping every 3–5 years. Skip that consistently, and you're shortening the clock on your drain field significantly.
How do you connect a property to city sewer from a septic system?
The process involves: pulling permits from your municipality, excavating a new sewer lateral from your home to the city main, properly decommissioning the existing septic tank per Benton County requirements, and passing a final inspection. Columbia Basin Plumbing handles the full process — from the permit desk to the inspection sign-off. Timeline is typically a few days of work once permits are approved.
Can a drain field be repaired, or does it always need a full replacement?
Sometimes a drain field can be repaired — resting a portion of the field, adjusting the distribution system, or addressing a specific blockage. But if the soil is saturated or biomat has built up across the whole field, repair won't hold. We'll assess the system honestly: if repair makes sense, we'll say so. If replacement is the right call, we'll explain exactly why before anyone picks up a shovel.
Do you offer septic pumping?
Septic pumping isn't a service we provide — that's a job for a licensed pumping company, and we're happy to point you in the right direction if you need a referral. What we do is the plumbing side of septic: installations, drain field work, repairs, sewer line service, and city sewer connections. If your system needs to be pumped as part of a larger repair or inspection we're already handling, we'll coordinate that for you.

Don't take our word for it — here's what Tri-Cities homeowners and businesses are saying on Google.
Thank you Columbia Basin Plumbing for the excellent service. We had a leak under our kitchen sink that we just couldn't locate. You were able to get out next day and take care of the problem.
Travis quickly found and fixed our water leak. But even more impressive was him crawling on his belly in a very narrow crawl space to get to the leak. We are very thankful and happy for the services at Columbia Basin Plumbing.
I had a valve on my hot water tank that needed attention in my Pasco rental. I’ve worked with Columbia Basin in the past through a previous place of employment. They are a great referral partner! Megan, the owner, was prompt with getting someone scheduled and out to the house. She’s very nice to speak with and I think Lee resolved my problem for my renters! Thanks Megan & Lee!
We love this family business! They came to our rescue at our business when we needed them the most. Excellent customer service, fair pricing, honesty and integrity. Highly recommended!
Very knowledgeable staff! Went above and beyond my expectations of customer service and experienced staff. Would recommend them to all my friends and family!
I highly recommend Columbia basin plumbing. Had an emergency after a pipe burst after a cold night. They were able to schedule me same day and fixed the issue with ease. Competitive prices had me charged hundreds less than I was expecting so I am especially grateful for that. Tyler was my laborer, good dude very good customer service explained and broke everything down easily for me to understand. I will definitely be calling them back for any plumbing issues in the future
Had them out for a dishwasher install. Went very smoothly, plumber showed up on time and did very clean work. I was able to get scheduled next day. Very happy and highly recommended.
They were able to come check out our hot water heater and replace it within 24 hours of us calling them, very responsive and reasonably priced! Would absolutely recommend!
Wonderful staff. Fair prices. Special thanks to Danny and Joey for excellent detection and service. Thanks Joey, for speaking with the claims adjuster!
Second time they're saved my bacon. They were fast, professional, helpful. Andres made sure I checked the work and explained what happened, why, and what he did to fix the problem. I recommend.
Called them @ 10am. And offered a 12pm appt. Extremely fast service, had the clog in my drain removed in less then an hour!! Would recommend for all your plumbing issues or needs!!
Called them to fix some issues we had at work they where fast and friendly and we will continue to use them
Super nice and friendly staff. Fixed my tub drain quickly. So happy they helped!!
Tyler is very professionalAnd on time.He had several little items to get done and was very thorough and very helpful answering questions I would recommend Tyler anytime.Thank you, be a basin for making my
This is the second time we've used Columbia Basin Plumbing and both times we've had excellent service. The first was to install new faucets throughout the house, a garbage disposal, and the second time was to install a new hot water tank. The price has always been reasonable. The guys that do the work have always been extremely professional. They have my business for life.
They responded and fixed my problem quickly, and for a great price!
I was dreading calling a plumber as I have never had to. Fast, friendly, excellent work at a price less than I had anticipated.
So grateful for Columbia Basin Plumbing. The office staff was so kind and understanding and great at communicating and getting our repair scheduled on a Friday afternoon. The plumber who came out was friendly and had us fixed up in no time along with some great advice for future repairs/projects.
I can't begin to say how impressed I am with Columbia Basin Plumbing! From the first second on the phone with Megan, all the way through finishing the job, they were courteous, knowledgeable, professional, reasonable, and do great work. They handled an entire replumb for us on an older manufactured home in a timely manner at a fair price. We are 100% satisfied and will use them in the future!
I gave them 5 stars even though there was a time hang up which is understandable. The gentlemen that came out was very professional and polite. He answered any questions I had and explained what needed to be done. They do charge one hour labor minimum which is typical but they would have been done in 20 mins... So the time hang up was the service man ran out of access panels and was gone for almost an hour running around town locating one to buy. This wasn't that big of a deal with me since I had no plans, but should be addressed in the review as it could be an issue if someone was on a time restraint. Their pricing I believe is fair they where less than half the amount Mr. Rooter wanted to charge. Overall, great experience.
Absolutely Amazing, Hero's I'd say, I needed my water heater installed and had called 20 other places before reaching them, by far the best customer service I've ever had, they squeezed me in the same day and got the job done! Would call them again if I ever need services. Thanks again to the Columbia Basin Plumbing Team.
I cant say enough good things anout them. They really care. They actually went out of their way to not only do a good job for a fair price but helped me deal with the results of a nightmare plumber who left me in a bad pinch. They moved their schedule around and made it happen. Theyre not just a great company... theyre genuinely caring... nice people.
Tyler was professional and faced with a very complicated issue. He kept on in very trying conditions until the situation was solved. Thank you!
Awesome company! Helped me over the phone no charge until we felt we found the problem! Thanks Jason!
I have used Columbia Basin Plumbing for multiple project big and small, every single time the work is completed on time and within budget. They are very knowledgeable and professional, I would highly recommend them for all your plumbing needs.
I can not give Columbia Basin Plumbing a good enough review! We had our newest grandson coming to visit our home for the first time and our water heater went out the night before. Both my wife and I were in a panic! We called Columbia Basin Plumbing and were connected to Jason. He assured us he would have everything taken care of for us first thing in the morning. Jason came out to our house at 8:00 the next morning, (a Sunday on top of all of this,) diagnosed, changed out, cleaned up, and left in under two hours! Not only was the customer service fantastic, the price was less than half what we expected. I wholeheartedly recommend Jason and his whole team at Columbia Basin Plumbing for whatever plumbing needs you have! We are very thankful to see there are still those contractors out there willing to sacrifice their personal time to make sure their customers needs are taken care of.
They were able to send somebody out the same day we called. The plumber, Tyler, was on time, fixed my issue, and was polite and courteous. The pricing was clear and fair. I would recommend them and will use this company for future issues.
Spoke to Donna and she was super attentive to my situation and scheduled an appointment for the following day. Next day Jeremiah arrived on time and went right to work figuring out the toilet drain back problem. He was excellent and worked fast and was extremely knowledgeable about what was being done. For a bad situation it was a pleasure having Jeremiah figure it all out and great attitude. Thank you Columbia Basin Plumbing.
Excellent work at a fair price from honest, helpful, and friendly staff. Never trust a 1 star review of this company. Any future plumbing work will start with a call to these guys
Excellent and fast service. They were at the house within an hour of calling to replace an expansion tank that had gone bad and flooded our garage. I would definitely recommend this company. The techs name was Russ. He worked quickly and was very courteous.
Fair and friendly service. I usually dont do these ratings....great!
They did a great job insalling my claw foot tub. Fast, friendly and skilled workers. I will be calling you guys for all of my plumbing needs. Thanks again!
I needed a plumber ASAP and they worked with me and had someone here quick. They went above and beyond normal customer service and I really appreciated that! Thank you!!
Great people and a great company! Columbia Basin Plumbing did a great job when our main sewage line collapsed. I cant believe how quick we were up and running again. The integrity, quality of services and fair price is incredible! I highly recommend!
Super friendly! Love seeing family business taking care of people so well! Amazing work! Thank you for your quick response!
Amazing customer service. A plumber you can trust! I highly recommend them. Their prices are very affordable.
Did a great job. Was there when I need someone fast. Kitchen drain plugged, was very fast and a very nice guy. Very affordable. Cleaned up the mess and was like I hadn't even had a problem with my drain.
Megan and Jason are by far the most professional and efficient business owners I've met in a long time. Each time we have called them to our house Jason has been there within the day or two. If somthing comes up Megan is quick to stay in touch as to when they will be out. I completely trust the work they do as well as their word and that says a lot. If your looking for honest, proficient, affordable work. These guys put they're whole hearts into what they do. Look no further!!! Thanks for everything, Maraiah and Justin
My husband and I were in the middle of moving and had our shower head break off in the wall and we just didn't have time to fix it our selves... Everyone else my husband called couldn't be to our old house to do the repairs for a few days and we just couldn't wait that long... We called Columbia Basin Plumbing and they were able to be out to the house within a few hours and had it fixed in less then an hour... Very friendly and professional!! And his rates were very reasonable!! They will be our first and only call of we ever need someone again!!
Amazing costumer service!!! Saved us from flooding our neighbors and fixed or irrigation pipe and stayed for a while to make sure everything was ok! Thank you again Jason!
I called when all the others I called said it was going to be weeks before they could come out they said they would come today. We talked about what needed to be done and he did the work the workmanship was great and the bill was less that I excepted I am very happy and will call them again
Columbia Basin Plumbing (Jason) was super fast, courteous, and very pleasant. Best price around. I will definitely be using this company again.
