Taking Shape

The outline of the new storm tank has been marked in blue paint before excavation and construction begins

At this location:

We are relocating an existing Combined Sewer Overflow (CSO) and building a new underground storm water storage tank.

Capable of holding nearly a million litres of water, storm flows will be redirected from overloaded sewers into the tank and stored until the weather subsides. The storm water will then be pumped back into the sewer network to flow to the waste water treatment works.

The site compound has been set up on Barbours Park

The CSO will divert storm rainwater run-off during extreme weather to prevent the sewers backing up into homes and businesses. Discharges will only happen when the now-increased sewer reaches capacity and will be screened to protect the environment.

At the same time, a new upgraded surface water sewer has been installed along the adjacent street – also called Barbours Park.

Work to relocate the CSO and build the new storage tank in Barbours Park began on the 3rd of February, 2025. During this time the entire park will be closed to the public. This is to ensure the safety of both the community and our workers.

Update February 2025

To build the new underground storm water storage tank Barbours Park will be closed for approximately two years from Monday 3 February 2025.

As well as the tank, new sewers have been installed along a short section of Bridgend to channel flows into the new tank. Stored water will eventually be pumped back into the sewer network and directed to the waste water treatment works.

We appreciate this work may cause some inconvenience. We are committed to working closely with the community to minimise disruption and make the process as smooth as possible.
