The soil in this area is heavy and wet, and the old septic tank was suffering from surface water ingress from a nearby yard. The installation of a new infiltration area was not possible because of high groundwater.
The BIOROCK on-site wastewater treatment plant is composed of a BIOROCK ST-1-3000 Primary Tank, a BIOROCK-S Treatment Unit, and a pumping kit. The treated effluent is discharged above-ground using a pump then diverted to a local existing soak-away in a field above the house.
