Droughts are naturally occurring events that occur when there is below average rainfall for prolonged periods of time. We need plans to manage our system when droughts happen.
The Water Act (2003) made it a statutory requirement for water companies to produce and maintain a Drought Plan. We update these plans every five years. Our Drought Plan sets out how we will manage our resources and supply system in dry years, to maintain our service to our customers.
In February 2014, Severn Trent Water published a Drought Plan to cover the period 2014 – 2019; this included their supply area in Powys, which now forms part of Hafren Dyfrdwy’s supply area. In July 2015, Dee Valley Water published a Drought Plan to cover the period 2015-2020; this included what is now Hafren Dyfrdwy’s Wrexham water resource zone, and the Chester water resource zone which now forms part of Severn Trent Water’s supply area.
As part of the five yearly cycle of updating these plans we are now developing a Hafren Dyfrdwy Drought Plan for 2020-2025. The draft plan will be submitted to Welsh Government in March 2019. Please note that drought measures for the Chester supply area will form part of the Severn Trent Water drought plan for 2019-2024, due to be published early in 2019.
