Sewage Plant at Providus Bank HQ, Victoria Island

Providus Bank is a commercial bank located in the heart of Victoria Island, Lagos’s major commercial district.

Owing to the high water table in the area, sustainability of underground concrete works was not possible. This very reason is why the client was excited to install the near zero electricity aerobic Biorock Bioreactor System.

With a daily load of 15m3/day, the STP consists of 1 No. Bioreactor, ECOROCK-5000 and 1 No 15m3 Primary tank, both tanks are made of HDPE and buried underground. Aeration of the tanks is provided by a wind driven ventilation system.

The client has since been satisfied with the very low operations and maintenance cost.
