Learn all about Ray's Twilight Septic Service.

We're your local eastern Washington septic pumping  company. We pump septic tanks of all sizes and types.

From late nights came the name "Twilight".

Back in 1954, Ray started septic tank pumping throughout the Tri-Cities in the evening as a side job. Since he was always working in the "twilight" he decided to call his company, "Ray's Twilight Septic Tank Co."

Tri-Cities Septic Service company truck and driver
Ray's Twilight Septic Service Team

A new beginning in 2019.

In 2019, we purchased Ray's Twilight Septic Tank Co. with the goal of continuing to help keep local Tri-City resident's septic tanks clean and healthy with regular septic pumping! We changed our name to Ray's Twilight Septic Service, but we still provide incredibly great service! We offer septic pumping in Benton, Franklin, and Walla Walla Counties in the Columbia Basin.

Pumped the septic system tank. Missed the first appointment without notice, apparently due to a sick driver. This is the reason for a four star instead of a five star rating. Made the second appointment and provided excellent service. I would definitely use them again.

We bought a house with a septic system and had not dealt with one before. We could not answer any of the questions asked when setting up the appointment, but the staff was patient and helped. They even contacted the health department to get a plan of how and where our septic was setup. Our service representative did a thorough cleaning and inspection. He explained to me what he was doing and what he was looking for during the inspection. After the cleaning he gave some recommendations and made sure everything was cleaned and secure. Thanks for the professional and exceptional job. We will definitely be calling Ray's for our next service!

Called Ray's to have our commercial office septic pumped, since the tank alarm was going off. Super polite, friendly service that suggested their electrician to look at it first, to possibly save us on the cost to pump it. Electrician came out promptly and confirmed it needed to be pumped, to which Ray's quickly scheduled it for the next day. Everything was efficient and done professionally. Very highly recommended!!

... They arrived on time and did their thing (pumped the tank).  In addition they identified a problem with the tank before the whole tank had to be replaced. The concrete lid was showing signs of decay.   They provided a quote to install a carbon vent to correct the issue and were able to perform the repair two days later.
