Case Studies

For two decades, Orenco Systems® has been researching, designing, and manufacturing innovative technologies for small community wastewater collection systems. Often called "pressure sewers" or "effluent sewers," more than 150 small community systems in the United States now use Orenco's ProSTEP™ Effluent Sewer equipment. Click on the images below to read complete case studies about two of these communities:

Diamond Lake, Washington. Installed in 1987, at an average cost of $5,540 per connection (excluding the cost of a treatment lagoon), Diamond Lake's ProSTEP Effluent Sewer serves more than 500 homes and one of the largest Boy Scout Camps in the country. Residents pay only $15 per month for maintenance service. Best of all, this lakeside community's new effluent sewer system saved Diamond Lake, restoring it to a pristine condition within three years.

Elkton, Oregon. Installed in 1989, at an average cost of $7,000 per connection, Elkton's ProSTEP Effluent Sewer and Recirculating Sand Filter serves 100 homes, stores, restaurants, and schools along the beautiful Umpqua River. Effluent quality coming out of the Recirculating Sand Filter meets Advanced Treatment levels, with BOD and TSS averaging 6 mg/L. And documented maintenance for the entire system averages less than one hour per day.
