Ecorock Wastewater Treatment Plant
Compact Wastewater Treatment Units - Septic Tank Upgrade

For small households to medium establishments

ECOROCK, a Non-Electric Two Stages Wastewater Treatment Plant

The ECOROCK unit is a small-sized wastewater treatment plant that caters from 6 to 30 persons application. The ECOROCK-system functions as a two-stages treatment plant. The raw sewage first enters a Primary tank to provide preseparation and initial breakdown of organic solids. The wastewater then passes through an effluent filter before discharging into the BIOROCK unit itself which incorporates the aerobic filtration process.

Where required the ECOROCK Series can be retrofitted to a traditional septic tank.
