Why we need the Prince of Wales Reservoir
The new reservoir is needed to:
• increase water storage for the community
•provide resilient emergency water storage for residents, businesses and public facilities in the area
• provide back-up water storage for operational reasons.
All Wellington’s bulk water supply pipelines bring water to
Wellington from Upper Hutt, and cross major earthquake
faults. It’s very likely that Wellington’s water supply will
be disrupted in the event of a severe earthquake. The new
reservoir will add capacity to Wellington’s water storage
network improving Wellington City’s resilience to disaster
events affecting water supply.

The reservoir will be built to modern seismic standards and to
a standard to ensure that it remains fully operational following
a significant earthquake.
Increasing the amount of water stored in the area will
enhance the operational resilience of the water supply
network by allowing Wellington Water to undertake essential
maintenance, repair and upgrade works of other reservoirs
with little or no disruption to local water supply.
