Water Quality  | NI Water News

NI Water’s number one priority is the quality and safety of your drinking water.

We can assure our customers that the water supplied from all our Water Treatment Works, which includes water abstracted from Lough Neagh, is safe to drink and use as normal.

On a daily basis, we monitor our raw water intakes from all sources, at our treatment works and at customer taps to ensure that drinking water supplied meets strict quality standards.

NI Water has a robust testing and sampling system which sees over 120,000 samples lifted and analysed each year. Sampling and analysis are carried out 365 days per year. Samples are taken from customer homes, reservoirs and treatment plants.

Drinking water supplied from the water treatment works which use Lough Neagh as their raw water sources, are designed with the potential for algae to be present and robust treatment processes are in place to manage this effectively.

We increase the frequency of algae monitoring over the summer months when the risk for algae in the raw water would generally be higher.

Increased levels of algae can cause an unusual taste and smell to water from your tap but does not pose a risk to health. The taste and smell can be earthy and/or musty. Therefore, while the water from your tap can be used in the normal way, we fully appreciate some customers might notice a difference in the taste and/or odour to their drinking water at this time.

Sometimes filter jugs, coffee machines and filters can be problematic if they have not been regularly cleaned or the filter has not been replaced in line with manufacturer’s instructions. It is also advised to keep these appliances out of direct sunlight and in a cool place.
