Annual Report 2011 - Watercare

Watercare Services Limited
2011 ANNUAL REPORT
Fresh water is a vital but limited resource, essential for the health and well-being of
everyone. Auckland is known for its relatively wet climate and each year the region
receives, on average, 1,220mm of rainfall. Rain collected in the Waitakere and Hunua
ranges is stored in Watercare’s 10 water supply dams before being treated at our water
treatment plants and sent to households. Auckland’s water supply is also augmented
by an underground supply in Onehunga and from a water take and treatment plant
on the Waikato River at Tuakau. Smaller ground and river sources also supply outlying
rural communities.
Wairoa Dam in the Hunua Ranges is
Auckland’s fourth-largest water supply
dam. It was built in 1975 and its lake
covers 98 hectares.
Watercare provides the community with
access to land in the Hunua and Waitakere
ranges and around the Manukau Harbour for
recreational use. It maintains walking tracks
and allows fishing by permit at Mangatangi
and Mangatawhiri dams. The Watercare
Coastal Walkway around the Manukau
Harbour is also very popular.
