Sent an email to Wind River they called me almost immediately, had an appointment setup for 3 days later. The technician they sent was kind and courteous, explained some septic things to me and then was on his way. Will use them in the future.

Honest and knowledgable!

Just wanted to rave about the great experience we had today with Wind River Environmental for our septic tank cleaning! Ruben was great, honest & knowledgable! Being new to the area, we had no clue & just used the well-known company that our neighbors & previous homeowners used. That company told us we had a crack in the tank when in turn we don’t… Ruben walked us through every little detail & answered every question we had with a smile! Highly recommended!

We keep our customers’ liquid waste systems flowing.

Let us keep yours, too.
