Emergency & Dam Safety Management

What to do in an Emergency?


Any emergency relating to CPWL infrastructure should be notified to the CPWL Emergency number.


The emergency number is operated by Answer Services (NZ) and is monitored 24 hours a day, seven days a week. Calls will be answered, details of the emergency will be taken, and your call will then be patched through to the on-call CPWL Maintenance Technician for initial response and, if necessary, escalation and response via the CPWL Emergency Response Plans and Dam Safety Management Plans.

Dam Safety Management

CPWL own and operate two large dams within the scheme area. CPWL takes Dam Safety very seriously and we undertake regular surveillance and monitoring to ensure our structures are performing as expected. We rely on engineering experts to provide us with reliable Dam Safety technical advice and we follow and enact their recommendations as appropriate.

Emergency Management and Response

Our Dam Safety Management programme is fully aligned with the New Zealand Society on Large Dams (NZSOLD) Dam Safety Guidelines (2015). We regularly review our Dam Safety plans, processes, systems and procedures to ensure they are aligned with current best practice. We regularly undertake external Dam Safety Reviews. External Dam Safety Consultants undertake both Intemediate Dam Safety Reviews (IDSR's) and five yearly Comprehensive Dam Safety Reviews (CDSR's)
