Southern Water enters latest phase of £13m work to improve water quality in Southampton Water

Southern Water has entered the latest phase of works to improve water quality and protect shellfish in Southampton Water.

As part this, a 50-tonne, 100ft tall crawler crane will be installed as work continues to improve Woolston Wastewater Treatment works.

This is part of works to build an underground shaft which will be used to store storm water, before it is pumped back to Woolston Wastewater Treatment Works.

The crane and 100-tonne piling rig will be used throughout July to install Secant piles. These piles will hold back groundwater while the storm shaft is dug. Once completed, the new shaft will hold around five million litres of storm water.

The water company said that through this and additional membrane filters it will be able to treat more water before it goes back into Southampton Water.

Southern Water is continuing to invest in the Southampton area following a £100 million transformation of the Woolston works in 2020 as well as investing £5.5 million upgrading Portswood Wastewater Treatment Works.

Work on the project is being carried out by the joint venture GTb between Galliford Try Environment and Binnies UK Ltd.

Project Manager for Southern Water, Jorge Rodriguez, said:

“We are serious about improving water quality in the Hampshire area, and protecting the precious environment across the areas we serve.”

Dominic Edwards, Site Agent at GTb, added:

“This is the largest piling rig and crawler crane we have used since forming the joint venture between Galliford Try and Binnies. Over the coming weeks and months there will be some significant changes to the site as we start to construct the storm shaft.”
