Twilight Septic: Born from Evening Service Runs in the Tri-Cities

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."

Carrying on the Legacy of Ray's Twilight Septic in the Tri-Cities

In 2019, we purchased Ray's Twilight Septic Tank Co. with the goal of continuing to help keep local Tri-City residents' 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 the Columbia Basin's Benton, Franklin and Walla Walla Counties.

With a deep-rooted commitment to the community, we ensure top-notch septic maintenance tailored to your needs.

Ray’s Twighlight service is the best because they’re always on time with a reminder and he reinstalled my baffles for me and did a great inspection and left my yard neat. Thanks for a great job.

They were the last to pump our tank. We didn't know where it was. They had photos on file from 98. Gave us the number of Dr Dan so he could expose our tank lids that costs extra. Raul was early to pump our tank. Thank You Ray's Twilight.

August 22, 2023

All of the above! Everything went very smooth. Even when I deleted my own appt on my calendar, they answered the phone confirmed the appt and everything was like clockwork! Definitely will recommend

Bruce Pratt

They arrived a little early, went right to work. When he finished pumping out the tank and washing it down he put the lids back on. I got a senior discount which was awesome and a receipt marked paid before he left. He also shared the condition of our system and some tips to help the system work better between pumping. Pleasant experience very professional. Well done!

Good service and right on time to have my septic tanks pumped. I had no idea how the septic system worked.

I now know we’re the filter that needs cleaning every six months is located. (I’ve lived here 5 years).

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!
