Until you have completed a Pre-Development Enquiry, or where required a Waste Water Impact Assessment, you will not be able to apply for an Article 161 assessment. When you have completed the Pre-Development process, which will identify a point of connection, you must apply for approval of any drainage system serving 2 or more properties, inclusive of lateral drains, for adoption at a future date under Article 161. Any person proposing to connect a sewer to the public sewer will require formal approval to connect, on the basis of a mandatory Sewer Adoption Agreement (Article 161).
Please note that the proposed development should have valid full planning permission prior to making a submission via the Self Service Portal. It should be noted that the applicant will be charged for reassessing submissions that do not meet the specific standards. A re-submission fee will be charged for:
If it is proposed that Northern Ireland Water are to complete the connection under Article 163
- you will be required to make the Article 161 application for assessment and the drainage design agreed in principle, prior to the connection being approved.
- the Article 163 connection should be completed in advance of the Article 161 Agreement being authorised.
You are required to submit an Article 161 Application via the Self Service Portal where you will be guided through what documentation is a mandatory requirement. A list of the required documentation is available at ‘Appendix A’ below.
The design of the drainage systems must be in accordance with the ‘Sewers for Adoption (NI) Current Edition’.
Please note that if the proposed drainage traverses an Adjoining Owners land, the third party land owner will be required to sign the Article 161 Agreement agreeing to said drainage to be laid through their land and the associated protected strip once adopted. All signatures will be via the Adobe Sign electronic process.
Land drainage and groundwater will not be permitted to discharge into the public sewerage systems either directly or via private drains or sewers.
The use of a Wastewater Pumping Station will be considered if no practical gravity solution is applicable. Please refer to www.niwater.com/services-for-developers_multi-unit-developments_wastewater-services_further-guidance-notes/ for the current Wastewater Pumping Station specification.
The use of a Waterwater Treatment Works will be considered if required as a result of the outcome of a Waste Water Impact Assessment. Please refer to developerservices[AT]niwater[DOT]com for the current Waterwater Treatment Works specification.
Under the Street Works (NI) Order 1995 a Street Works Licence is required by any person or organisation who wishes to place or retain apparatus in a street. This may be applicable from the boundary of the site to the public sewer or watercourse.
- If the connection is proposed within an adopted road/street the excavation/reinstatement can be completed by Northern Ireland Water or an approved contractor, who must have a street works licence issued from DfI Roads for the location.
- Northern Ireland Water is an approved Utility Contractor and can carry out the full service connection including the excavation and reinstatement, the cost of this service will be included in the quotation, via the Self Service Portal (New Connections). If it is proposed that Northern Ireland Water are to complete the connection under Article 163, this must be completed in advance of the Article 161 Agreement being authorised.
- Northern Ireland Water, under the prescribed charges, will make the connection to the sewer, only after the mandatory Sewer Adoption (Article 161) has been applied for and under assessment by Northern Ireland Water, prior to any connections being made, and lay the associated sewers and manholes within the street.
It should be noted that the applicant will be charged for reassessing submissions that do not meet the specific standards. A re-submission fee will be charged for:
- Submission of amended designs.
- Failure to submit drawings incorporating amendments previously requested by Northern Ireland Water.
- There is no fee for the first re-submission of the design drawings that incorporate previously requested amendments, however there will be a fee for every re-submission thereafter.
- For an amendment to any details noted on an issued Article 161 Agreement.
It is an offence to connect to the public sewer without first obtaining the consent of Northern Ireland Water.
The drainage work should not commence on site until an authorised Article 161 Agreement is in place, any appropriate charges paid and any other conditions complied with. However if any drainage is laid in advance, it is at the developer’s risk as it may need replaced to receive Northern Ireland Water approval.
