The Single Unit Impact Assessment application is a referral application following the Pre-Development Enquiry process and needs to be submitted as soon as is practicable and prior to any formal planning submission.

Please complete all sections, in order to avoid delay or return of your application.

NI Water provides an Impact Assessment service to assist you in identifying any possible constraints that may be associated with servicing your proposed site in terms of water and wastewater infrastructure. The Impact Assessment can assist you in understanding the potential costs and timescales involved in servicing a site prior to land acquisition or in advance of the submission of a planning application.

You should only submit a Single Unit Impact Assessment where you have been advised by NI Water through a single unit PDE application response.

Should you wish to take advantage of this service, please complete the Single Unit Impact Assessment application form (SU-IA) and forward with the appropriate fee to the address below.

On receipt of the fixed fee, NI Water will produce a site specific report detailing potential mitigation measure you can undertake to overcome identified capacity constraints to permit you to connect to our infrastructure in areas where capacity is Limited.

The Impact Assessment process does not guarantee the applicant connection to the NI Water/Wastewater network, nor can NI Water commit to specific construction timeframes.
