Ms Margaret Attridge:

Our priority in the short term is getting the message out to as many people as possible. Other than the top 20 sites, we are using the local authority management teams to cascade the information with regard to instant management response down to all the plant caretakers. Our first touchpoint is to get the messages down to the caretakers.

Concerning the other sites, as part of our audit of the top 20 sites, we are doing an alarm and inhibit or alarm and shut down review of them. That review will be rolled out across all 800 sites. We have a long-term plan, where we are doing drinking water safety plan assessments of all our treatment plants across the country. This comprises a full asset audit and operations performance audit of the plants. It will take a number of years to get to the entire 800. We are taking the alarm-inhibit piece of the drinking water safety plan out and doing it in advance. We will start programming works over the coming months to carry out that review to make sure all the alarm inhibits are working properly and all site staff have awareness of how the controls are working.
