A brief history of water supply in North Shore City
Settlement on the North Shore began in the
late 1800’s with residential development in Devonport, which then
spread to Takapuna, Birkenhead and Northcote. By the time the
Harbour Bridge opened in 1959 the population on the North Shore had doubled and was estimated to be around 80,000.
The North Shore's water supply was originally
drawn from Lake Pupuke, which collected rainwater from the surrounding
200-acres within its low crater rim. In 1941 the North Shore Drainage
Board was formed and recommended seeking an alternative source of water
supply. Auckland City was approached to provide bulk water supply to the
North Shore.
North Shore Boroughs Water Supply Act
Before the bulk water supply from Auckland City, many
boroughs were using water from Lake Pupuke and there was a need to
coordinate use of the lake. A Board of Health inquiry into the
conditions at Lake Pupuke in 1941 resulted in the adoption of the new
North Shore Boroughs Water Supply Act. In 1924 alternative sources of
water supply were again investigated. The outcome was that Devonport,
Takapuna and Northcote all entered into contracts with Auckland City for
bulk water supply.
Under the provisions of the North Shore Boroughs Act,
continued limited use was made of Lake Pupuke and a filtration,
treatment and new pumping plant were installed. In 1944, however, control
was further rationalised with the introduction of the North Shore Water
Conservation Act, which abolished the Water Board and vested control of
the lake in Auckland City. Subsequently, work on the treatment plant
station was abandoned in favour of full Auckland City supply. The lake
supply was maintained as an emergency supply.
During the early stages of development, before water was
provided by Auckland City, water was supplied to households and
businesses from a variety of sources:
Devonport: In 1894 Devonport’s water supply was
pumped from Lake Pupuke to a reservoir at Mt Victoria. This reservoir
remained operational until 1928 when it was designated for stand-by use only.
This reservoir is part of the Devonport water supply network today and
along with the rest of city is supplied with water purchased from
Watercare Services Limited.
Northcote: In 1908 Northcote’s water supply
came from the western shore of Lake Pupuke. In 1941 in an attempt to
obtain better quality water, a deep borehole water supply was brought
into service. This was only partly successful but it did provide
Northcote residents with adequate water until 1945 when the change to
Auckland City bulk supply occurred.
Takapuna: From 1910 until 1921 Takapuna was
supplied by Northcote. Devonport then took over the Takapuna supply.
Birkenhead: In 1910, a pumping station was
installed on Lake Pupuke for water supply to service the Birkenhead
area. This was completed in 1913 and pumped water to a reservoir at
Verran’s Corner until 1934. The Birkenhead Borough then made the
change to Auckland City bulk water supply.
Since 1959 North Shore City’s water supply line has
crossed the Auckland Harbour Bridge. This line originates from Khyber
reservoir and is less vulnerable than the now abandoned under-harbour
section of the Hobonsville feeder.

North Shore City water supply today
North Shore City is today supplied by two pipes; one that runs
from Watercare Services' Khyber Pass reservoirs under the
harbour bridge, and one that runs from Waitakere,
across Upper Harbour Drive. The water is then distributed via Watercare
Services Limited and North Shore City Council reservoirs and pipes. |
