Pre-development enquiries

For a full capacity study for proposed developments, our pre-development enquiry service will provide information regarding the impact the proposed development will have on our existing water network and its ancillary assets, together with identifying any associated costs involved with upgrading or diverting our assets to provide a water supply for the new development.

Before submitting your request please read the Pre-Development Enquiry Guidance which explains the procedure in more detail. Supporting layout and location plans should also be attached to your Pre-Development Enquiry Application form.

Once you have completed your application please return it with any accompanying plans or schedules to our Development Control email address: developmentenquiries@nwl.co.uk.

When should I make a Pre-development enquiry?

Pre-Development Enquiries are only required for developments of 3 or more properties (or the equivalent in terms of commercial and industrial developments). If your development is smaller please go directly to the Adoption of a New Sewer and/or New Water Supplies sections on our website.

How much will it cost?

The fee varies depending whether your enquiry relates to a water supply, sewerage or both. In the case of water supply only, the fee increases with the number of houses. For sewerage only, or water and sewerage, the fee is fixed.

How long will it take to get a response?

We will acknowledge receipt of your application (completed form, fee and scaled location plan) within 5 days. Your enquiry will have a unique reference number.

A response to your enquiry will be given as follows:
Water Supply enquiry: We will respond to you within 21 days of receipt of a completed application.
Sewerage enquiry: We will respond to you within 21 days of receipt of a completed application.
Combined Water Supply and Sewerage enquiry: we will respond to you within 21 days, you may receive responses for sewerage and water separately.

If more detailed investigations are required before we can give you a full response, we will notify you of this and provide an estimate of when a response to the enquiry will be given.

Please Note: we will only process your enquiry if the form is completed and fee and site plan included. Incomplete enquiries may need to be returned to you for more information, resulting in a delay to the response.
