Hafren Dyfrdwy

Hafren Dyfrdwy is the coming together of Dee Valley Water and Severn Trent to form a new water service for our customers in Wales. It means we’re committed to low water bills, great customer service and helping people in the country we proudly serve.

The name Hafren Dwyfrdwy reflects the two main rivers (River Severn and the River Dee) in the new region echoing our dual heritage. The use of Welsh as the primary language reflects that that this is a Welsh business operating in Wales.
