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 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 €40 million euro will be invested in the upgrade and standardisation of disinfection systems currently installed in over 830 public drinking water treatment plants.
The National Disinfection Programme will:
- Improve drinking water quality
- Ensure compliance with current Drinking Water Quality Regulations
- Remove supplies from the EPA's Remedial Action List
- Reduce the risk of Boil Water Notices or THM formation
- Provide improved control of the systems
What is involved as part of this programme?
The Disinfection Programme will be carried out in two phases:
Phase 1: Water Treatment Plant Assessment
This stage involves the assessment of the condition and performance of the existing disinfection systems at water treatment plants across the country. This will determine the works required to ensure that the treatment plant disinfection process meets the specified requirements.
Phase 2: Necessary Upgrade Works
Some of these works may include upgrade of chemical storage and dosing infrastructure, upgrade of ultraviolet (UV) disinfection systems, upgrade of monitoring systems and generation of Critical Process Alarms.
We are currently identifying and planning the appropriate mitigation measures to be carried out at water treatment plants throughout the country to achieve water quality compliance. To date, we have assessed over 450 sites and commenced upgrades to over 130 water treatment plants.
