Septic System

The septic system is attached to a building in order to treat the greywater coming from the sinks and the blackwater coming from the bathrooms. The system is made of two septic tanks and six filtration chambers.

The septic tanks are concrete cylinders with a 10’ internal radius surrounded by walls made of ecobricks (plastic bottles filled with trash) bonded with a cement-based mortar. Toilet blackwater is first brought to the septic tanks where the solid and foam components are filtered. Each septic tank includes an air vent for degradation of the solid waste via air exchange.
