Following discussions with the Health Service Executive, Uisce Éireann confirmed that customers served by the Cordangan Water Treatment Plant must boil their water before drinking.
The utility said the alert was prompted by elevated turbidity levels in the raw water supply, which have interfered with the treatment process at the Cordangan facility.
Turbidity refers to the cloudiness of water, often caused by suspended particles, and can reduce the effectiveness of disinfection.
Supply to parts of the area was disrupted, with the network in the process of refilling. Water is expected to be fully restored to affected properties by morning. However, once supply resumes, customers have been instructed to boil water before consumption until further notice.
Pierce Faherty of Uisce Éireann said efforts are under way to resolve the issue swiftly.
“The network is currently replenishing, and all homes and businesses should have a full supply restored by morning but customers must then boil that water.
“We know how inconvenient a Boil Water Notice is for our customers, and I can assure them we are doing everything we can to resolve the issues and lift the notice.”
The notice applies to those supplied by the Cordangan plant in Tipperary Town and surrounding areas.
Customers can check whether their property is affected by visiting the Uisce Éireann website and entering their Eircode, or by contacting the customer care helpline, which operates around the clock on 1800 278 278.
A map of the impacted area is available on the supply and service section of the website.

Uisce Éireann said its drinking water standards, governed by EU regulations, operate with what it described as wide safety margins.
Where potential risks to water quality are detected through its monitoring and testing regime, the HSE is consulted and boil water notices are issued as a precautionary measure to safeguard public health.
The utility added that immediate corrective action is taken in all such cases to address the underlying cause, with the aim of lifting restrictions as soon as it is safe to do so and in agreement with the HSE.
Customers registered as vulnerable with Uisce Éireann are being contacted directly. The public is reminded that water remains safe to drink once it has been boiled.
