Developer Charges

Welcome to Hafren Dyfrdwy Developer Services, on this page you’ll be able to find information about our developer charges relating to making new connections to our water and sewerage network.

On 1 July 2018 Dee Valley Water was integrated into the Severn Trent family to create our new Welsh business known as Hafren Dyfrdwy. This means that Severn Trent now solely service our customers in England, including Dee Valley’s Chester customers, and Hafren Dyfrdwy service our customers in Wales, including Severn Trent’s Powys and Monmouthshire customers.

What it means for developers

We have two separate charging booklets within Hafren Dyfrdwy. One that is relevant for the previous area known as Severn Trent’s Powys and Monmouthshire. The other is relevant for Dee Valley’s area in North East Wales. This is because we've retained the charging policies within those areas.

Our 2020-2021 charges

Area Charges Booklet
Wrexham and surrounding areas (formally part of Dee Valley Water) Charging booklet North & North East Wales
Powys & Parts of Monmouthshire (formally part of Severn Trent) Charging booklet Powys & Parts of Monmouthshire

If you’re not sure which charging booklet applies to you, please take a look at the interactive map at the bottom of this page.

If your site is located in the ‘pink area’ the North East Wales booklet will apply.

If your site is located in the ‘blue or purple area’ the Powys and Monmouthshire booked will apply.

We've created a handy estimator tool to help you estimate your new mains requisition charges 2020/2021

This tool asks a series of questions to provide an estimate of costs which apply to your scheme. The tool assumes a number of features about your site so that the estimate outputs are reflective of typical mains requisition schemes. We review this tool periodically to ensure that the assumptions contained within it cover the majority of schemes and that the outputs provide a reasonable estimate of costs in the greater majority of cases. This tool, for 2020/21 charges, was last updated in February 2020

 

Developments in Chester

Chester has now become part of our English company (Severn Trent), you can visit the Severn Trent website to find all the information you need, including how to contact them.

Hafren Dyfrdwy sewer adoptions

Our Welsh business is both a water and sewerage undertaker and will adopt sewer assets that are constructed in Powys and parts of Monmouthshire. These were previously adopted by Severn Trent.

Sewer assets constructed in North East Wales will continue to be adopted by United Utilities or Welsh Water, depending on where your development is located.

Our 2019-2020 charges

We publish our new connections charges before they become applicable on 1 April, therefore the information above relates to our 2020-2021 charges. If you’d like to see our 2019-2020 charges (which are still in use until 31 March 2020) please use the links below:
