Certification Letter issued by VDH for a 5 Bedroom home using an alternative system design. (An alternative septic system is a system that is different from the common traditional style septic system. An alternative system is required when the site and soil conditions on a property are limiting, or when the wastewater strength is too strong for the receiving environment (i.e. restaurants). Alternative systems clean the wastewater (reducing the organic load, nutrients , and pathogens) before dispersal to the receiving environment. Alternative systems require less soil. In other words, the drainfields are smaller, and the standoffs to water table and soil restrictions are reduced. With conventional systems, the soil is cleaning the wastewater just as much as the septic tank. With alternative systems, most of the cleaning is taking place in the advanced treatment unit, which is a tank or container with a blower and/or filtering media.)
