An Overview

Work carried on the Brighton and Hove Waste Treatment Works as part of Southern Water’s £300 million environmental improvement scheme, in order to treat the 95 million litres of wastewater generated each day by over 250,000 residents of Brighton and Hove and the surrounding area. After treatment the cleaned water will be recycled back to the environemnt 25kilometers of-shore.

The scheme, which began in July 2009, includes the construction of a number of 8 shafts upto 15m diamter and 40m deep and pumping stations which will facilitate the passage of waste water from the existing sewer network through a number of interconnecting tunnels to a new waste water treatment plant located in Peacehaven. Once treated the final effluent will be transported via sewer out fall into the English Channel.

JGL constructed numerous underpinned shafts with SCL bell outs and eye formations along with connections between the shafts (by TBM/roadheader/microtunnel boring machines) as well as the final long sea outfall on a curve 1km out to sea.
