Question:
To ask the Minister for Infrastructure to detail the number of wastewater treatment stations that have been recorded as being over capacity in each of the last five years.

The management of public wastewater infrastructure is an operational matter for NI Water. However, I have sought the requested information from NI Water and have been advised as follows:
