The first full scale implementation of MABR

Faced with residential and industrial growth, Yorkville-Bristol Sanitary District took a chance on then-novel Veolia wastewater intensification technology.
May 8, 2025

Yorkville-Bristol Sanitary District was the first full scale implementation of Veolia's ZeeLung membrane aerated bioreator (MABR) technology in the world in 2017. Faced with continuous residential and industrial growth, estimates to expand the plant across a creek running through the property was cost-prohibitive. Then came a promise of new wastewater intensification technology for a fraction of the cost.
