2020 NI Water Customer Tap Results

2020 IMPORTANT INFORMATION

Please be aware that during 2020 due to the ongoing COVID-19 pandemic, with the agreement of the Drinking Water Inspectorate (DWI), NI Water reduced potable water sampling as part of the plan to protect staff and customers, whilst maintaining assurance that there was no risk to public health from public water supplies.
This included the cessation of all sampling at customer taps with effect from 16th March 2020, with a reduced number of parameters sampled upstream at Service Reservoirs. From 18th May 2020 sampling returned to the regulatory frequencies, with the exception of a small number of parameters which are customer tap specific.
Customer tap sampling remains at designated Service Reservoirs or other identified fixed point locations. This has created a shortfall in regulatory sampling at customer tap for the calendar year 2020. During the period however, NI Water maintained full sampling and analysis at its Water Treatment Works and downstream Service Reservoirs as per regulatory requirements.
This along with customer tap samples taken at designated fixed points in the distribution system, ensured that the quality of water supplied to our customers was effectively monitored and maintained throughout the period.

This dataset comprises results taken from Customer Taps by NI Water during 2020 to meet the requirements of the Water Supply (Water Quality) Regulations (Northern Ireland) 2017 as amended. Samples collected from customer taps are taken at random addresses in each water supply zone. A water supply zone is a designated area with a population of no more than 100,000 supplied with water by one treatment works or blended water from several works. The number and boundaries of water supply zones are subject to change according to operational requirements as supply sources to areas are adjusted to meet demand and infrastructure developments. To preserve our customers' anonymity, only the postcode is given for each sample and not the individual addresses.
