Remedial works to dams in Northern Ireland, Belfast

About this event

Northern Ireland Waters impounding reservoir portfolio secure drinking water for over 700,000 people. However, these invaluable assets also pose a risk to approximately 66,000 people living within the downstream flood inundation area should a catastrophic failure of the dam occur.

These assets must be inspected monitored and maintained, to a very high standard to protect the population downstream and secure the water supply function.

This presentation will cover the following:

  • the background to the safety inspection of Dams for Northern Ireland Water. The monitoring requirements and the process of carrying out safety reports will be explained in the context of the proposed new legislation.
  • examples or recent remedial works completed at a number or Northern Ireland Water Reservoirs, including Silent Valley, Ben Crom, Spelga and the Woodburn cascade system.
  • A discussion on the environmental, management and programming challenges associated with works to reservoirs.
