What assessment has the Cabinet Minister made of the environmental report recommendations regarding the Cwrt Sirhowy housing development in Cwmgelli, and what action has been taken following the flooding to ensure there will be no repeat incidents?

NRW are responsible for enforcing the Environmental Permitting Regulations 2016. They (NRW) received several reports of silt pollution impacting the Cwmgelli Brook from November-December 2025 - the discharges were also linked to the flooding of a nearby property.

Following site investigations, the source of these silt discharges was identified as a nearby housing development. NRW undertook enforcement action to ensure no further impact to the watercourse occurred as a result of the silt pollution.

Caerphilly County Borough Council are the Risk Management Authority responsible for managing the risk of flooding at this location. They are in discussions with the housing developer and residents in order to resolve the issue.
