The West Virginia On-Site Sewage program provides rule interpretation and technical assistance on conventional
and non-conventional on-site sewage systems. Conventional systems include gravel and pipe, gravel-less pipe,
and chamber systems.
Non-conventional systems include home aeration systems, low pressure dosing systems, holding tanks and recirculating
sand filters. These alternative systems are used when a conventional system has failed and cannot be repaired by
conventional means, or when soil conditions are extremely poor. Alternative systems may be considered for new
construction only if the lot is two acres or larger in size.
The on-site sewage program also issues permits for residential waste water systems with surface water discharge
which are 600 gallons/day or less and which qualify for a
West Virginia Department of Environmental Protection N.P.D.E.S. permit.
