Wastewater Treatment

Wastewater Disposal

System Overview
Biological treatment of wastewater historically has been the way water has been purified for centuries. On-site disposal of wastewater is recycling the clean purified waters into the soil using technologically advanced distribution systems. This reuse recharges ground waters and can be used in landscaping irrigation. These systems can be applied to small residential, commercial and large flows such as towns, strip malls, truck stops and any other non municipality serviced sewage treatment need.
Treatment and Disposal Process

Wastewater is pretreated by settling solids in a conventional septic tank. Treatment occurs when wastewater is sprayed over a media filter (foam, peat, sand, linen), where it slowly percolates downward. As the effluent passes around and through the media it contacts large populations of aerobic organisms and degradation of the wastewater strength occurs. The effluent is recirculated until desired dispersal quality is achieved. Disposal is mainly by subsurface drip irrigation fields.

System Requirements
The systems are operated under the auspices of a State Operating Permit issued by the Tennessee Department of Enviornment and Conservation, Division of Water Pollution Control. A competent system owner is required for the responsibility of the system (Chartered Property Owners Association, municipality, privately owned public utility, or individual). A licensed operator is required to operate and run the system. Monitoring and analysis is typically required quarterly on small flows.

Frequently Asked Questions

Are there odors? Typically there are none with a properly managed system.

Are the systems hard to operate? The system function with computerized control panels and need checked from time to time. Modern telephone communications (telemetry) allows the monitoring of systems conveniently from a remote location.
Are the systems expensive? Sometimes the systems are more expensive to build than hooking to a sewer, but in the long run a provately owned utility company can operate a system for less than many large municipal systems.
