SYDNEY’s WATER SUPPLY

Sydney today has a water storage capacity described as “one of the largest domestic water supplies in the world, able to store

four times as much per capita as New

York’s water supplies and nine times as much as London’s

(Flannery 2005)

SYDNEY’s WATER SUPPLYSydney –

2.5 million megalitres of water in 21 dams

OR 2.5 million Olympic Sized

Swimming Pools

SYDNEY’S CATCHMENT AREAS Sydney’s demand for water is currently met by: A network of 11 major dams supplying drinking water A large number of recycling schemes which save drinking water

for drinking Transferring water from the Shoalhaven River A wide range of water saving programs for homes, businesses

and farms.

These Five catchment areas encompass the 21 dams. Warragamba Dam Upper Nepean dams Shoalhaven system Woronora Dam Blue Mountains dams

WARRAGAMBA DAMWarragamba dam provides 80% of Sydney’s

drinking water

Capacity: 2,031,000 megalitres

OR

2,031,000 Olympic Size Swimming Pools

9,050 square kilometres captured

WHY WARRANGAMBA?Firstly, it had a large catchment area and

secondly the river flowed through a long, narrow gorge.

A comparatively tall and narrow dam capable of impounding a vast amount of water could be built

Its potential was identified as early as 1845, HOWEVER, plans deferred during the construction of the Upper Nepean dams between 1907 and 1935.

An increasing demand for water from expanding population, and a record drought from 1934 to 1942, forced the development of Warragamba Dam to ensure a reliable water supply.

HOW THE DAM WORKSWarragamba Dam supplies bulk water to

three Sydney Water filtration plants

(Prospect, Orchard Hills and Warragamba),

where it is filtered and distributed to people

living in Sydney and the lower Blue Mountains.

HOW THE DAM WORKSThe best quality water is

selected and drawn

through screens on three outlets in the upstream face of the dam.

before it reaches the end user. Sydney’s water network consists of 21 000 km of pipes.

WATER RESTRICTIONS

Mandatory water restrictions came into force across Sydney, the Illawarra and the Blue Mountains on October 1 2003.

Currently in level 3

Also save resources, time and money regarding water treatment and helps the environment.
