Information Requests

This page has been designed to allow easier access to water related information requested by consultants when carrying out environmental assessments. It contains a link to the WMU Information Request Web Viewer and links to associated documents. This web viewer provides surface water quality, abstraction, industrial and domestic consent, pollution incident, groundwater authorisation and groundwater information, the main types of data requested.
Additional information on overall groundwater quality, groundwater dependent terrestrial ecosystems and protected areas is on the NIEA Catchment Data Map Viewer available on the Digital Download page.

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

If you require any additional water-related information, Groundwater or Marine related data, contact WaterInfo@daera-ni.gov.uk

2021 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 Digital Dataset Download 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.
