Bypass benefits from Hydro-Brake® Drop

Hydro-Brake® Drop provided simple, non-disruptive flow control that prevented environmental damage and avoided greater expense.

Situation

A new 4 mile bypass was built by Costain at Church Village for Rhondda Cynon Taff Council, Wales, to reduce traffic disruption on the A473 road between Pontypridd and Talbot Green.

Problem

The challenges in managing surface water both from natural and developed features were considerable, including run-off from the surrounding hilly countryside, existing drainage from several disused railway installations and groundwater from disused mineshafts. If this had not been carefully diverted around the new road, it could have created unplanned standing water or even undermined structures.

Solution

Costain selected Hydro-Brake® Drop to prevent excess flow force at the discharge, enabling them to meet the maximum design flow of 2,000 cu ft / min through a 23" pipe reducing to 18".

Outcome

Hydro-Brake® Drop provided a simple and non-disruptive flow control solution that prevented environmental damage and avoided the need for much greater expense.

"Cutting into old rail ground structures can create all sorts of trouble as no-one knows what is in there, all the records had disappeared. It was much simpler to install the Hydro-Brake® Drop, and with less visual impact too."

- John Lee, Project Manager, Costain
