Project Description

The owner of a gas station and convenience store in Graham, Washington came to us in a bind. His existing onsite system was failing so dramatically that untreated sewage was bubbling up and running in rivulets into an adjacent wetland. Our first step was coordinating consulting to reduce the water volume generated by the facility. From there we designed a system for treating 900 gallons per day of high strength wastewater. But the biggest challenge in this project was obtaining regulatory approval for the site. Using “Effluent Quality-Based Drainfields” guidance, we negotiated and gained approval to install a drainfield half of normal size in order to maximize the setback from the adjacent wetlands. The result: environmental and health risks were solved and we gave them enough additional capacity to add an espresso kiosk.

Our old system was in crisis and we weren’t sure if we could even stay open. ADC was not only able to design a cost-effective system that expanded our capacity, but they steered us through all the governmental red tape to make it happen. ADC really saved the day for us – Tom Noble, Project Manager, Global Alliance (ARCO)
