Reference excerpt

The Woollahra Reservoir or WS022 is a heritage-listed underground reservoir at 5R Oxford Street, Centennial Park, New South Wales, Australia. It was designed and built by the NSW Public Works Department. The property is owned by Sydney Water. A sign attached to a building on the site states that this is known as "Centennial Park number 1 Water Reservoir Underground WS0022". The reservoir is adjacent to Centennial Park Reservoir. This reservoir is closer to York Street than Centennial Park Reservoir. The area is enclosed by a high fence and a sign on the main gate states: WARNING KEEP OUT" and that trespassers may be prosecuted.

History The Centennial Parklands, as it stands today, represents 190 years of colonial history. The settlers had an immediate impact on the lives of the Gadi people whose clan territory takes in most of the Sydney peninsula. Gadi country extends between what is now Darling Harbour and South Head, and includes Centennial Park, Moore Park and Queens Park. Close to where Centennial Park and Moore Park are today, an area that became known as the Kangaroo Ground was recorded on a map engraved by J. Walker in 1791 or 1793. This map shows the location of what the English called the Kangaroo Ground, in the clan territories of the Gadi. The richer soils and park like atmosphere observed here by Tench and others would almost certainly have been created through regular firing by the Gadi to keep the undergrowth clear and attract kangaroos and other large game to the area for hunting.

Sydney Common Centennial Parklands, comprising Centennial Park, Moore Park and Queens Park, are part of the Second Sydney Common dedicated in 1811. As the settlement of Sydney began to develop it became necessary to set aside common land on the outskirts of the town. On 5 October 1811 Governor Macquarie proclaimed the 200 hectares (490 acres) to the south of South Head Road as the Sydney Common, for use by the public. The common land contained a vital resource in the form of a constant supply of pure water due to the natural aquifers present in the Botany Sands system. In 1820, Macquarie set aside the water reserve in the east of the Sydney Common. Between 1827 and 1838, Lachlan Water Tunnel (Busby's Bore) was built providing a supply of freshwater to a terminal in Hyde Park. It remained Sydney Town's sole source of water supply until 1858, when it was supplanted by a scheme to pump water from the Botany Swamps, located further to the south.

Lachlan Swamps & water supply The swamps, located within the Sydney Common, were naturally aquified and were an ideal source of water. In recognition of this precious resource, the Lachlan Water Reserve was founded in 1820. The Tank Stream supply of water for Sydney was inadequate and had a high level of pollutants, in 1825, the colonial government set up an enquiry into the use of the Lachlan Swamps to provide a water supply to Sydney. John Busby, a mineral surveyor, was appointed to design a water system to convey the water from the swamps to the town centre. Busby originally considered conveying the water using iron pipes, but assessed this would be too expensive. Finally he proposed a long tunnel be constructed, entirely through Crown Land.

Busby's Bore The Lachlan Water Tunnel, better known as Busby's Bore, was Sydney's first piped water supply. The "Bore" or tunnel was, on average between 1.7 metres (5.5 ft) high by 1.4 metres (4.5 ft) wide and carried water from the Lachlan Swamps to Hyde Park. The whole length of the Tunnel was 3,700 metres (12,000 ft) and capable of holding 6.8 megalitres (1,500,000 imp gal) gallons and 15 days' supply of water. Sydney Council took control of the Water Supply in 1842 and was responsible for the whole of the Lachlan Water Reserve. In 1861, it was decided that the whole of the Sydney Common did in fact belong to the people of Sydney. Common land was given to the authority of the Municipal Council. Moore Park was then laid out. To meet increasing demands for water, portions of the Swamp were dammed in 1872, resulting in an embankment just below what is now known as Kensington ponds, and a series of seven dams throughout the swamp. The first major development encroaching onto the Sydney Common was the siting of Victoria Barracks on Oxford Street on the north east of the common. Designed in 1838 and completed ten years later, the Barracks was strategically sited between Port Jackson and Botany Bay to prevent an enemy invasion. The soldiers soon established the Military Garden, and by 1852 they had added the Garrison Cricket ground and a rifle range on land to the south of the barracks. In 1866 the Sydney Common was given to the Municipal Council of Sydney for development under the Sydney Common Improvement Bill of 1866.

A public park In the second half of the nineteenth century, parts of Sydney Common were made into parkland. Lord Carrington, the Governor of NSW 1885-1890, advocated the city of Sydney should have a large recreational space in the fashion of a "grand park". Sir Henry Parkes, the premier, recognized the potential of this proposal and facilitated its realisation. Charles Moore JP, the Mayor of Sydney from 1867 to 1869, worked on developing a public park for the recreation of the people of Sydney. Allotments of land alongside Oxford Street were sold to fund the developments and soon Moore had overseen the construction of Randwick and Moore Park Roads and the creation of a public park incorporating the land around them. Charles Moore, Director of the Sydney Botanic Gardens, supplied the distinctive tree plantations.

Moore Park In 1866 Sydney City Council dedicated 153 hectares (378 acres) of the north west section of Sydney Common as a recreation ground for the public to help alleviate growing pressures for outdoor activities, particularly organised sports. The area was named Moore Park in 1867 after Charles Moore, Mayor of Sydney City Council 1867-1869. Moore Park became the focus for major sporting events and entertainment facilities with the establishment of the Zoological Gardens in 1879, the Royal Agricultural Society Showground, and the first course of the Australian Golf Club in 1882.

Queens Park Queens Park was created by the Centennial Celebration Act 1887. By 1895 it contained an eleven-hole golf course which was removed to Botany in 1899. Since the 1930s Queens Park has been used as a sports field by Christian Brothers College, Waverley and various local sporting groups.

Worked examples

Example 1 — a first encounter with Woollahra Reservoir

Start with the simplest possible case. Write down what Woollahra Reservoir claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Woollahra Reservoir before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Woollahra Reservoir ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Woollahra Reservoir

In research
Woollahra Reservoir appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Woollahra Reservoir in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Woollahra Reservoir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1880 establishments in Australia, Buildings and structures completed in 1880, Centennial Park, New South Wales, so understanding it makes those chapters shorter.
In everyday life
Look for Woollahra Reservoir outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
