Ashco-A-Corporation has strived to be a leader in the sewage treatment industry since April, 1972. We've manufactured thousands of sewage treatment devices ranging from traditional septic tanks to 70,000 GPD+ commercial systems. We have a wide variety of clientele ranging from the individual homeowner to conscious developers. We have frequently provided services to such agencies as: The USDA Forest Service, Department of Transportation, WV State Parks and Recreation, Northrop Grumman, and many others, all the while working hand-in-hand with the offices of the Department of Environmental Protection and many Health Departments across the tri-state area. Ashco's personnel is second to none. We have a highly trained service and maintenance department, a well equipped in house plumbing facility, an efficient installation crew, a excellent manufacturing unit, a precise drafting department, and office personnel ready to assist you at any time. Our goal is to ensure that our costumers in the area know exactly where to turn to when it comes to their wastewater needs and to expose the need for technologies that have the least impact on the ecosystem.
