Mr. Cian ? D?naill:

The OPW has changed its work practices. It is unrecognisable from 20 years ago. The main purpose of the Arterial Drainage Act and the schemes that were developed was to provide drainage outflow. There was some flood protection benefit to provide drainage outflow. Along with IFI, we have developed guidelines over the years on how to carry out this work in an environmentally friendly way.
