What are discharge consents?
Discharge consents include conditions outlining the quality and quantity of wastewater discharges. These conditions have been drawn up to ensure that the waste can be absorbed by the receiving water without damaging the aquatic environment or breaching national or European Commission (EC) standards.
The discharge consents include a range of different types of discharge:
- Domesic discharges which are single dwelling related discharges.
- Private Sewage Infrastructure which are sewage related discharges for 2 or more dwellings and commercial activities.
- Wastewater Utility Discharges which is wastewater infrastructure operated by a Public Water Utility Company.
- Trade/ Process Wastewater Discharge
- Site Drainange Discharges
Domestic discharge consents
A consent to discharge waste from a single domestic property is granted by the department, subject to the recommendations made by the local council’s Environmental Health (Rivers) Officer.
Holding a Consent to Discharge does not confer any legal rights of access, control or ownership for a property. NIEA require a map/plan which shows the location of the proposed treatment system and discharge point where required. This does not necessarily contain the same level of detail or match exactly any plans provided under a planning application or a Land Registry map outlining legal boundaries and we do not cross reference application maps with Planning; Land Registry or any other public bodies. If any proposed infrastructure is outside the boundary of property owned or controlled by the applicant, any easements; wayleaves; rights of way or access arrangements that may be required are the responsibility of the applicant. NIEA do not verify that such arrangements are in place.
Domestic Consents Public Register
The Domestic Consent Public Register is now available to search for domestic consent details online. All domestic consents and maps for consents granted from 1992 to present are available to download: Domestic Consent Public Register

Application guidance
Domestic Consents are for discharges from a single dwelling only. For sites of 2 or more dwellings, please first seek advice from NI Water regarding connection to the public sewer network. In the event that NI Water do not have capacity in their foul sewerage infrastructure you will need to apply to NI Water for a waste water impact assessment.
This will determine if there are any mitigation measures the developer can take to achieve a connection to NI Water infrastructure.
Please see https://www.niwater.com/services-for-developers for further details.
Private sewage infrastructure discharge consent
The preferred means of sewage collection and disposal is through connection to the public foul drainage system provided by NIW, the sole water utility provider in Northern Ireland.
If it is not possible to connect the proposed development to the main sewer, then discharge consent under the terms of the Water (NI) Order 1999 will be required for the discharge of sewage effluent from the proposed development. Applicants should follow the guidance and information provided below for Industrial discharge consent.
No commencement of works or any discharge of sewage effluent shall take place before a consent to discharge has been granted by NIEA.
This is to ensure responsible sewage management AND protection of both public health and environment.
Please refer to Consent Application WO1 Form including WO1 Annex 5 and Guidance which outlines relevant information required to ensure a complete application is submitted. Failure to submit all of the relevant and required information will result in the return of your application.
For a Private Sewage Infrastructure Consent to Discharge application must include the following information but not limited to:
- A NIW Pre-development Enquiry which is within 12months of issue. This document provides evidence that the applicant has formally engaged with NIW.
- In areas where there is a collection system present however NIW have indicated that a Wastewater Impact Assessment (WWIA) is required to assess the options for connection, NIEA require the submission of a WWIA. This evidence demonstrates that every option has been considered by the applicant and NIW to secure connection to the NIW sewage collection system.
For residential developments of two or more dwellings, NIEA will require evidence of valid Pre-Development Enquiry from NIW and depending on advice given a Wastewater Impact Assessment (WwIA) may also be required. If, following NI Water advice, developer constructed sewage treatment is the only option, a suitable treatment plant, which can meet the specification for NI Water adoption under an Article 161 agreement will be considered.
NIEA will require all private sewage infrastructure (pumping station and treatment) relating to residential dwellings to meet the NI Water specification for adoption.
NIEA application process includes consultation with NI Water and aligns to the NI Water Article 161 Adoption process. No private sewage infrastructure will be granted unless a valid Article 161 Agreement and bond is in place.
Commercial properties which cannot connect to the NI Water infrastructure are also considered to be Private Sewage Infrastructure and are required to apply using the industrial discharge consent application process outlined below.
Industrial consent application
The Industrial discharge consent application process allows for the specific technical analysis of proposals relating to private sewage infrastructure, trade wastewater (process wastewater) and site drainage activities.
Below provides the range of application forms and guidance documents dependant on the activity applied for:

- Applicant's guide for consent to discharge for premises other than a single domestic dwelling
- Transfer ownership or change name of a discharge consent (WO4)
- Transfer ownership or change name of a discharge consent for a Private Pumping Station (WO5)
As part of the application form, applicants are required to complete the appropriate annex for the industry type:
- Sewage discharged under emergency conditions consent (WO1 - Annex 1)
- Trade effluent and site drainage discharge consent (WO1 - Annex 2)
- Apply for a fish farming discharge consent (WO1 - Annex 4)
- Apply for a sewage effluent discharge consent (WO1 - Annex 5)
Please note that for activities requiring a Waste Management Licence under the Waste and Contaminated Land (Northern Ireland) Order 1997 or a Part B PPC permit under The Pollution Prevention and Control (Industrial Emissions) Regulations (Northern Ireland) 2013, a consent to discharge under the terms of the Water (Northern Ireland) Order 1999 may also be required.
It is now possible to apply for these permissions in parallel, see below for guidance on how to apply:
The regulations (Water (NI) Order 1999) provides a 4 month timescale to determine an application for a Consent to discharge, an application can take up to 4 months to process. You should ensure you allow sufficient time for your consent application to be processed. In some cases the NIEA will ask for further information under Schedule1 Paragraph 1 Sub Paragraph (3) and (4), in this case a notice will be issued seeking the submission of the required information within a specified time frame. The application will be paused until the notice for further information has been complied with.
NIEA will also consult with a number of consultees to assist in the technical assessment of an application for an Industrial Discharge.
It is particularly important to note that NIEA carry out an assessment under the Habitats Regulations 1995, The Environment Order 2001 and the Water Environment Regulations 2015.
Where a relevant designated site has been identified to be in unfavourable status detailed technical assessments will be required and may not be granted.
Applicants must note that the granting of a discharge consent will be wholly dependant on the quality of the receiving aquatic environment and the sensitivity of the location. The technical assessment of an application of consent to discharge will test if suitable controls can be put in place to protect and enhance the aquatic environment.
Proactive compliance assessment is applied to those discharges perceived to present the most risk to the environment. NIEA carry out sampling of the quality of the effluent discharged to ensure compliance is achieved. If non-compliance is detected through the sampling regime NIEA apply the DAERA Enforcement Policy to achieve compliance and protect the environment.
Application fees and charges
NIEA are required to recover the costs of regulation under the Water Order 1999.
