Welsh Water have built a track at the end of De Braose Close into the woods as they wish to install a sewage pipe that will connect to a Pumping Station in Hailey Park, so that the sewage will flow to Cardiff Waste Water Treatment Works as an alternative to Cog Moors Waste Water Treatment Works.

The pipe will be connected to a valve installed in the system and controlled via a cabinet placed at the end of De Braose Close. The pipe will pass deep underneath the railway and river and connect to an underground pumping station accessed by the lane to the Hailey Park changing rooms from Ty-Mawr Road.

This work is due to the Plasdŵr development, which will connect to the sewage pipe in Herbert March Close. Work is planned to start mid 2022. Further details are on the Cardiff Planning System here. 

The location of the De Braose cabinet and the Hailey Park pumping station are on this map.
