Information Requests
This page has been designed to facilitate public access to water quality related information. It contains a link to the NIEA Water Information Request Viewer, links to associated documents and key contact details for water quality related information.
The viewer provides information on surface water quality under the Water Environment (Water Framework Directive) Regulations 2017. It also contains information on water abstractions, industrial and domestic discharge consents, pollution incidents, and groundwater information.
For information relating to private water supplies, contact Drinking Water Inspectorate dwi@daera-ni.gov.uk
For Northern Ireland Water (NIW) - discharges and public water supplies, contact NIW directly waterline@niwater.com
For information relating to Domestic Consents, the Public Register is now available to search for consent details online - Domestic Consent Public Register | daera-ni.gov.uk
Information relating to groundwater aquifer classification, superficial aquifers and groundwater vulnerability is available online directly from the Geological Survey of Northern Ireland’s (GSNI) GeoIndex website. Please refer to the Regional Groundwater Aquifer and Vulnerability Classification Guidance for further information.
2024 WFD classification of water quality has been undertaken, details of which are available at NI Water Framework Directive Statistics | daera-ni.gov.uk

Further Information
Water Management publishes a growing number of water-related datasets on the Open Data NI website. Data are downloadable and available in a variety of formats.
Some layers displayed on the mapper are available on the WMU Spatial Datasets page, which can be downloaded and used within your own project. Follow the guidance on the web page.
A full description of WFD classification for freshwaters, including chemical standards and with references to supporting documents, can be found on the UK TAG Water Framework Directive site.
The River Basin Management page gives details of WFD progression in Northern Ireland.
The Environmental Change Network includes sites for Northern Ireland, and long term data sets can be accessed via their website.
If you require any additional freshwater, groundwater or marine-related data, contact us at WaterInfo@daera-ni.gov.uk.
