National Disinfection Programme

A national programme of works to improve the quality of drinking water across the country

Why does water need to be disinfected?

The protection of public health and the delivery of clean, safe drinking water is the top priority for Irish Water. Disinfection is an important part of the water treatment process. Chlorine is the most commonly used disinfectant in water treatment in Ireland. It is added at the water treatment plant and for larger networks may require boosting at key locations including reservoirs and pumping stations to ensure the correct levels of chlorine are maintained throughout the entire network.

What are the benefits of this programme?

As part of this programme over €65 million euro will be invested in the upgrade and standardisation of disinfection systems currently installed in over 864 public drinking water treatment plants, pumping stations and reservoirs.

Next steps:

We are currently identifying and planning the appropriate improvements to be carried out at water treatment plants throughout the country to ensure the continued delivery of safe drinking water. To date, we have assessed over 805 sites and completed upgrade works to over 211 sites.

​The upgrades undertaken as part of this programme will:

  • Improve disinfection systems and standards at the plants

  • Ensure compliance with current Drinking Water Regulations

  • Provide improved control of the systems at the plants

  • Improve the security of drinking water quality for residents and businesses

  • Future proof the security of supplies

  • Reduce the risk of Boil Water Notices or THM formation
