On-site Alternative Septic System Design

Gay and Neel, Inc. has been designing Alternative Wastewater Treatment and Disposal Systems for over fifteen years. Designs have ranged from small single-family systems to large public systems serving residential subdivisions, schools, and commercial applications. System designs have been installed and are operating throughout Virginia. Gay and Neel, Inc. has designed over 200 septic systems in the past for sites where a Health Department designed conventional system was rejected. Gay and Neel, Inc. designs for a wide variety of Wastewater Treatment Units and Disposal methods. Your soils are the determining factors in what type of treatment and disposal will be needed for your lot. Below is a description of a typical treatment unit and a typical drip installation. While these are typical descriptions, all systems are uniquely designed to fit the characteristics of your soils and your lot.

*It should be noted that the Media Module is
typically placed below final grade.
The blower may also be remotely located
up to 50' from the treatment tank.

The system shown to the right (click image for larger picture) utilizes a MicroFAST 0.5 Aerobic Treatment Unit to effectively treat the raw wastewater from a three bedroom, single-family residence. The system consists of three components: The media module that is placed in a baffled septic tank, the small regenerative blower (seen in the picture to the right), and the alarm box (seen in the picture mounted on the blower housing).

Some lots require the design of a subsurface drip disposal system to disperse the treated effluent. A drip disposal system allows for shallow placement of the lines. This feature renders sites viable that were previously unsuitable. A typical drip system consists of five components: a drip disposal pump tank, a control panel, a headworks control box (the component seen in the picture to the left), the supply and return manifolds, and the dripline installed in the disposal area.
