Development enquiries

Step 1: Before you apply

There are some key things you need to know before you’re ready to apply for a new connection. A development enquiry is used to find out if our existing network can supply your proposed development with water and take away your proposed sewerage flows. It will also confirm if your development will affect existing Hafren Dyfrdwy assets. It is normally for larger development sites prior to full planning permission being granted or for large commercial properties that will have a high water usage.

Step 2: Apply

When you're ready, you will need to complete a development enquiry application form and send it to us along with the following supporting information:
  • A location plan;
  • A copy of a site layout plan;
  • Full details of the proposed development including flows/storage details;
  • The correct application fee 

Once we have received your application we will confirm receipt and provide you a reference number. This will then be assigned to a member of our design team who will be your point of contact during the design stage.

Step 3: Water response

What will it include?

The more information you can provide us with at this stage regarding the development type and the water usage/sewerage flows the more detailed and tailored our response can be. Our standard response for water enquires will include:

  • a copy of our water records for the area;
  • confirmation of any apparatus we have that will be affected by the proposals;
  • information about our ability to provide water for your development and how it should be supplied;
  • where appropriate details of any offsite work needed to reinforce our network to supply the development;
  • estimated costs associated for the water mains or service connections proposed to serve the site.

The application charges cover the work we need to respond to a normal enquiry. If the flow requirements are such that more extensive modeling/evaluation is required for an optimal solution to be determined an additional payment will be required. Where this situation arises we will, in our enquiry response, notify you.

Step 4: Sewerage response

What will it include?

The more information you can provide us with at this stage regarding the development type and the water usage/sewerage flows the more detailed and tailored our response can be. Our response for drainage enquiries will include:

  • a copy of our sewer records for the area;
  • confirmation of any apparatus we have that will be affected by the proposals;
  • information about our ability to drain the site, including restrictions on discharge rates;
  • where appropriate details of any offsite work needed to connect the site;
  • detail of any further work we need to provide an optimal solution to connect the site to our networks.

The application charges cover the work we need to respond to a normal enquiry. If the flow requirements are such that more extensive modelling/evaluation is required for an optimal solution to be determined. Where this situation arises we will, in our enquiry response, notify you.

Step 5: Follow up work

After the development enquiry is complete if your development is going ahead you will then need to complete the relevant application to progress to getting water on site or sewers approved. Any previous development enquiry reference number should be provided as this will assist us to progress your application and enable us to see what has previously been assessed.
