Learn all about Ray's Twilight Septic Service.

We're your local eastern Washington septic tank company.

From late nights came the name "Twilight".

Back in 1954, Ray started pumping septic tanks in 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."

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.
