Residential system solves drainfield problem
Problem: The owners of a residential home in Chapel Hill, North Carolina, had a conventional septic system with a drainfield that dispersed into poor soils. When the drainfield failed and needed to be replaced, the lot was too small for a new one and sewer service was unavailable.
Solution: Engineer Kevin Davidson of Agri-Waste Technology decided to install an AdvanTex AX20-RT unit with UV disinfection from Orenco Systems. This would provide an extremely high level of wastewater treatment through use of a packed-bed media filter and ultraviolet disinfection. The treated effluent is intended to be so clean that it is expected to meet NPDES permit limits for surface discharge into a ditch or body of water, eliminating the need for a drainfield.
Result: The North Carolina Department of Water Quality approved the permit. After purchasing equipment from Orenco dealer AQWA, the installation crew completed the entire project in only three days. “AX-RT is the best unit, when you look at aesthetics, installation cost, ability to treat waste and support from Orenco,” says Davidson. “Compared to other technologies, I would grade Orenco at the top.” 800-348-9843; www.orenco.com
