Ernesto Reveles, Operations Supervisor says "Our system is been up and running since 2005 and it is still operating at the same level as 7 years ago. The Enviroquip MBR Plant is very reliable and easy to maintain, replacing parts and components is easy."
DESCRIPTION
The Big Oaks plant treats domestic wastewater from nine high‐end homes constructed for the Tribal Elders and waste from a RV dump station. The final effluent is reused as irrigation water, which was another driver pushing the technology selection towards membrane bioreactor technology. ENVIROQUIP® MBR Technology is fully certified under California Department of Health Services, Title 22, as a reuse technology.
The MBR facility came online in December 2004. It has proven to be very reliable and has provided the Sycuan Band of Mission Indians with an extremely low‐maintenance, high‐quality treatment system.
