AMP8 Wastewater Networks

Dŵr Cymru Cyfyngedig (DCC) Welsh Water intends to initiate a tender process to secure delivery of Wastewater Networks associated works from November 2025 for up to 8 years. DCC is currently reviewing the precise structure, and nature of works to be undertaken, to both enhance, maintain and extend its current wastewater network assets.
