Bridge over troubled bridge is ‘egg-cellent’

Posted: Friday 19th January 2007

When Southern Water commissioned a wastewater flood protection scheme in the heart of East Sussex, it left Southern Water’s contractors 4Delivery with a dilemma – how to get to the site.

The scheme was to take place in farmland only accessible by crossing a stream. However there was no suitable way across the stream, a tributary of the River Cuckmere at Riverdale Farm, Horam, for any construction traffic.

Therefore the first task for 4Delivery was to build a temporary bridge. Site Manager, John Whittington said “Where work is taking place in the local community it is essential that Southern Water and 4Delivery protect people’s property.

“The farmer’s existing bridge would not have been able to take construction vehicles, so we had to build a temporary bridge before we could start the project.” The steel bridge is nine metres long and was installed in a single day. Sections were lifted into place by a 55 tonne crane.

The £750,000 environmental improvement scheme will further safeguard homes in Vines Cross Road and Millbrook Close, Horam against flooding. A 300 metre “egg” shaped sewer is being installed beneath Brookside and Riverside chicken farm. The work will also involve an overflow chamber being upgraded and the existing sewer across Waldron Ghyll being upsized.

Gary Sayers, Senior Contracts Engineer for Southern Water, said: “We’re very pleased to be able to help protect residents’ properties from flooding. At times of heavy rainfall, the new overflow tank and sewer will be better able to hold storm water than at present.”

Work began in January 2007 and is expected to be complete by the summer.

This project is part of Southern Water’s five year environmental improvement programme as the company works hard to tackle the risk of flooding from sewers across Sussex, Kent, Hampshire and the Isle of Wight.

4Delivery is a consortium comprising United Utilities, Costain and MWH. It is carrying out £750 million worth of environmental improvement and water quality schemes across the Southern Water region between 2005 and 2010.
