Pre Development Enquiry (PDE) application needs to be submitted as soon as is practicable and prior to any formal planning submission.
Completion of all sections is essential in order to avoid return of your application. Please refer to our guidance details below before completing your application.
The Pre-Development Enquiry Response will advise the applicant on the following:
- Status of receiving Waste Water Treatment Works
- Current availability of water and sewerage infrastructure to accommodate proposed flows – foul, storm and water
- Anticipated points of Connection.
- Proximity to Existing Assets within the site boundary (& referral to required assessment of protective measures)
- Further requirement (as applicable) for the developer to apply for a Water and/or Wastewater Impact Assessment.
- Further requirement (as applicable) for the developer to apply for an Odour Assessment
- Copy of NI Water Mapping records relevant to the site (Please Note Disclaimer).
Pre Development Enquiry (PDE) applications can be made to NIW to obtain information about the availability and capacity of water and sewerage infrastructure to service future development. NIW will advise if the existing infrastructure can accommodate the proposed development and provide detail on the anticipated points of connection. During a PDE assessment, NIW may identify potential capacity or odour issues which require further analysis. As a result a further detailed assessment may be requested by NIW. This is known as an Impact Assessment.
Note: NIW is committed to delivering new economic and housing growth, sustainably. In some cases, where our existing infrastructure is overloaded, NIW may have to refuse/defer new connections in order to protect the environment and our customers from flooding. The applicant will be notified of specific development constraints as part of the PDE process.
All applications MUST include the following:
- A Site Location Plan 1:2500 map (LPS ACE map will suffice) with the site boundary clearly indicated in red and relative to an existing feature. Any other land owned by the applicant should be shown with a blue line around its boundaries, and if a public right of way exists within or adjoining the site, it should be outlined in green. The 12 figure OS Grid Reference (x,y co-ordinates) of the approximate mid-point of the site is also required to allow the location to be accessed quickly and to avoid confusion when viewing on our map server.
- Planning references of all extant and live planning applications
- Extant Planning – if your site has extant planning and the approval date is more than 5-years, you must provide a Certificate of Lawful Existing Use or Development to confirm that the planning is extant.
Trade Effluent Discharge
The Developer must contact NIW Trade Effluent Team to seek consent for a Trade Effluent discharge. The discharge of Trade Effluent without consent is an offence and may result in legal action being taken. Further information and a Trade Effluent Application Pack can be downloaded from the NIW website at https://www.niwater.com/trade-effluent/.
Returning completed forms
The PDE Response will be valid for a period of 18 months and should formal approval to make connections to the public water and sewerage networks not have been granted by NI Water within this timescale, a further PDE will require to be submitted to ensure that capacity currently identified as being available to serve this proposal, still exists.
