Communities in Fanad, Carrigans, and Letterkenny will benefit from essential reservoir cleaning works taking place this week to help safeguard drinking water supplies and protect water quality.

Regular reservoir cleaning helps maintain drinking water quality by keeping this vital infrastructure clean, supporting a safe and dependable water supply for customers.
The cleaning programme will begin at Croghan Reservoir in Fanad on Tuesday, 10 November, with works taking place between 8am and 6pm.

Works will then take place at Dunmore Reservoir in Carrigans on Wednesday, 11 November from 2pm onwards. The later start has been scheduled to help reduce the impact on local schools.

The programme will continue at Carnamuggagh Reservoir in Letterkenny on Thursday, 12 November, with works taking place between 8am and 6pm.

While every effort will be made to minimise disruption, customers supplied by these reservoirs may experience reduced water pressure, temporary discolouration or intermittent supply during and shortly after the works. Normal water supply is expected to return following completion of the works.

Damien O’Sullivan, Uisce Éireann Water Network Operations Manager for Donegal, said: “Regular reservoir cleaning plays an important role in protecting drinking water quality and ensuring customers can continue to rely on a safe and dependable water supply. We have carefully planned these works to help minimise disruption, including scheduling the works at Dunmore for later in the day to reduce the impact on local schools. We thank customers for their patience and understanding while these essential works are completed.”
