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.

Raul was on time and was very informative in issue of what ended up being a broken lid after cleanout. He offered up options and what it would need to make the repairs. He also was very knowledgable on the newer tanks versus the old concrete and again had alot of ideas on how to replace versus repair. Very happy with this company and the technicians.

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!
