Services for Developers

About us

Northern Ireland Water recognises the importance of supporting development and regeneration and confirms its commitment to delivery of services for householders and developers.

Who are Developer Services?

Developer Services are responsible for the provision of services associated with all aspects of development including first time service appraisal, diversions, extensions to the watermain distribution system and sewer network, watermains in new development and Developer Services adoption of sewerage systems.

Predevelopment Enquiry (PDE)

It is beneficial to find out at an early stage in the process how your proposed development could be serviced with a water supply, where your drainage system would connect to a foul sewer; surface water systems and is there adequate capacity in the receiving wastewater treatment works (WWTWs).

You will be told if development is within the development limit in proximity to a WWTW, and if the sewer catchment has negative capacity. There may be benefit in having this information before you submit your planning application or even prior to purchasing a proposed site as it may highlight potential issues early in the development process. This information can be obtained by applying for a PDE.

We will work closely with you to ensure you receive water and sewerage services in a timely and professional manner, in accordance with our policies and procedures.

If you require further assistance please contact Developer Services Coordination Team on 03458 770002 (Mon-Fri, 09:00 to 16:30, excluding Public / Bank holidays)

If you wish to request a site visit to locate / trace Northern Ireland Water infrastructure or to request, disconnections or shut downs for watermains, please direct your query / request to Waterline[AT]niwater[DOT]com or Telephone 03457 440088.

Northern Ireland Water reserves the right to change, amend and update Guidance Notes and Application Forms on an ongoing basis. It is advisable to check out the current version online prior to making a new application.
