Dogs in the workplace have been shown to reduce stress, improve communication, and increase employee job satisfaction. Our favorite rescue boxer Duke spreads sanitation joy both in and out of the office.

The Columbia River Gorge is more than just great scenery; it’s a place where thousands of people live, work and play. Having the largest fleet of service vehicles gives us a distinct advantage when scheduling your service. The Bishop Sanitation main service territory covers the entire Gorge territory from east to west – on both sides of the river. Even If you’re located outside the Gorge, just give us a call. We can help.

I had Bishops pump out my septic tank. The situation was chronic by the time I had called them. They showed up quickly; very quickly. Their charges were reasonable. I appreciated the professional manner in which I was treated by the people on the phone and at my home. I would highly recommend.
