Drought plan

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 updated our Drought Plan in 2019 and held a public consultation on the new draft Drought Plan between 15 July and 6 September 2019. We reviewed the feedback received during the consultation and have prepared and published a Statement of Response (SoR) on this webpage. This details how we have addressed all of the comments and suggestions that we have received from stakeholders. 

Following permission from the Welsh Government, we have now published our Drought Plan.



We also undertook a Strategic Environmental Assessment (SEA), a Water Framework Directive (WFD) assessment and a Habitats Regulation Assessment (HRA) of our Drought Plan to take environmental impacts into account.

To request copies of the WFD and HRA assessment reports please contact us.
