Orcas Sewage Design has been designing onsite wastewater treatment systems since 1980. We serve homes on Orcas Island and greater San Juan County as well as Island, Whatcom and Skagit counties. If you need an inspection or maintenance of an existing system, our trained technicians will perform your service cheerfully and promptly. We’ll provide you with a report of what we found and explain any repairs needed. If you’re planning a new home and need an onsite septic system, septic designer Rick Petro will listen to your needs, personally assess your property and create a unique design that fits your goals.
