MAROONDAH WATER SUPPLY SYSTEM (UPPER AND CENTRAL SECTIONS) - History
Melbourne's early water supply
Melbourne's earliest water supply was derived from the Yarra River and its contributaries. As Melbourne grew, factories and industries were established on the banks of the rivers and creeks and together with the lack of a sewerage system, the water supply became severely polluted. In 1853, the Yan Yean Water Supply System was completed, allowing water from the Plenty River to be brought to Melbourne via a gravity fed system. This was the first large scale engineered water supply system in Victoria and was critical to the development of Melbourne in the gold rush period. By 1870 Melbourne's population had reached 200,000, which was the maximum that the Yan Yean had been designed to serve. Further works to augment the Yan Yean system, and provide a cleaner water supply were completed during the 1870s and 1880s, however a larger system with a consistently higher water quality was soon required.
Preparing for the Maroondah Water Supply System (1880 - 1886)
In 1880 the Watts River and its tributaries in the Yarra Ranges were surveyed by J H Davies, and recommended as suitable for a diversion weir (a small structure which diverts water) or a reservoir (a large body of water contained by a dam). As well as increasing water supply, water purity was also an important consideration in a time when there was significant concern about typhoid and other infectious diseases. To preserve the purity of the supply, the Watts River catchment of 43,300 acres was gazetted in 1886 as a closed water catchment. This caused objection from the tourism and logging industries who were reliant on access to the surrounding countryside. It also meant that the entire township of Fernshaw located within the catchment area was compulsorily acquired, and the entire town was removed. Houses, the hotel and the post office were auctioned and moved, and everything else was demolished and burnt, including cesspits.
Stage One: The Watts River Scheme (renamed the Maroondah Water Supply System) (1886 - 1891)
The design and construction of the Watts River Scheme (renamed the Maroondah Water Supply System at its opening in 1891) was overseen by William Davidson. Davidson was not an engineer, but had trained as a surveyor on the Ballarat goldfields. In April 1873, he was appointed assistant to the Superintending Engineer of the Melbourne Water Supply, Charles Taylor. In 1878, Taylor was dismissed, leaving Davidson in charge when a bridge carrying a section of pipe within the Yan Yean Water Supply System was washed out, severing the water supply. He managed to restore water to Melbourne within three days and was rewarded by being appointed Superintending Engineer. He oversaw the expansion of the Yan Yean system before developing the Watts River Scheme.
Due to the plentiful flow of the Watts River, it was decided to proceed with the construction of a weir rather than a reservoir. Construction began on the Watts River weir in 1886 which was 100 feet (30.5 m) long and constructed of Portland cement concrete, with stone coping. The smaller Graceburn Weir was also constructed at this time, as well as the gravity fed aqueduct which ran for 41 miles (66 km) from the weir to the Preston Reservoir through 6 miles (9.6 km) of tunnels and more than nine miles (14.5 km) of inverted siphons. With the inevitable construction of the dam and reservoir in mind, Davidson had the foresight to ensure that the tunnels were large enough to carry increased flows in anticipation of the need for additional supply in the future.
The system was opened on 18 February 1891 by the Governor of Victoria, the Earl of Hopetoun, who renamed the scheme 'Maroondah' which was incorrectly thought to be the indigenous name for the area. In the same year, the Melbourne and Metropolitan Board of Works (MMBW) was formed to manage the city's water supply and sewers.
Stage Two: Construction of additional weirs (1891-1909)
Among the first works carried out by the newly formed MMBW was the construction of new weirs at Donnelly's Creek and Sawpit Creek in 1893 to provide additional flow into the Maroondah aqueduct. The MMBW also purchased land in Badger Creek where another weir was completed in 1909. These new weirs were connected to the Maroondah aqueduct via open channels, pipes and siphons.
Stage Three: Construction of the Maroondah dam and reservoir (1917 - 1927)
In the early twentieth century, Melbourne's population began to increase again, making further demands of the existing systems. It had been assumed that the Maroondah dam would be constructed to alleviate this demand, however its location would make it difficult to service the elevated and rapidly expanding eastern suburbs of Melbourne. In response, C E Oliver, Engineer in Chief of the MMBW, proposed a new diversion weir high on the O'Shannassy River. Discussions generated so much political debate that a Royal Commission was called in 1909 to determine a decision. The commissioners included William Davidson, creator of the Maroondah scheme, and the Commission came down in favour of the O'Shannassy scheme. The Commission also acknowledged that there would eventually be a need for the Maroondah dam. In 1917, preparations for the Maroondah dam finally began. The valley floor was cleared by timber cutters, and in the following year, the Watts River was diverted.
The first elements of the Maroondah dam to be completed were the valve houses, followed by the outlet tower in 1925. The dam itself was completed in 1926. Materials were brought to the site by an aerial ropeway which operated for almost nine hours each day, for six years. Forty two large buckets were filled with sand or cement before making the 45 minute journey to the dam site. The buckets then returned to the station where they were refilled. Although steam power was used where possible, most of the construction was completed by the labour of the several hundred men on site at any one time.
The reservoir was filled in 1927, submerging the original Watts River weir. The capacity of the aqueduct was also increased at this time, with an upper 'berm' added to deepen the open channels, and duplication of some of the siphons. Water supply was further increased with the construction of a second diversion weir on Badger Creek upstream from the first weir, in 1928. During the 1930s and 40s, the Maroondah Reservoir was one of Melbourne's largest and most visited reservoirs. It is now one of the smallest, but still plays an important role in supplying water to Melbourne.
Gardens and plantings
Gardens and picnic areas were traditionally provided at weirs and dams. The weirs associated with the Maroondah Water Supply System were located in areas which had been popular with tourists as places for outdoor recreational activities since the 1860s. When the weirs were constructed, picnic areas were provided and the bush settings were complimented with the planting of firs and ferns. In the 1930s the weirs at Donnelly's, Graceburn and Coranderrk/Badger Creek were planted with pines for their antiseptic qualities, and toilets were installed. Fireplaces were built and firewood was provided. Pines and other conifers were planted along the aqueducts as it was thought that the dense foliage would filter pollution. It is likely that the Coast Redwoods (Sequoia sempervirens), oaks and other exotic species at the former location of the township of Fernshaw were also planted at this time. Most of the picnic areas have been damaged through bushfires and storms and very few built structures survive.
The flat area below the Maroondah dam was also to become parkland. It was the view of the Board of the MMBW that as the 'great engineering work belonged to the people . it should be available to the people as a place for recreation.' The indigenous vegetation was to be retained, however the area was destroyed by bushfire in 1926. Parts of the site had also been compromised by the building works, leaving it unsightly and unsafe. In March 1927, the Water Supply Committee asked E G Ritchie, Engineer of Water Supply to develop a planting plan. He did this in association with Hugh Linaker, landscape gardener who then became closely involved with the development of the park for the next fifteen months. Not only was he involved in the planting plan, but he also advised on pruning, monitored the suitability of the trees to the area and it is also likely that he supplied the trees from his own nursery. Linaker planned the planting using his typical contrasting combinations of evergreen and deciduous, natives and exotics, and upright and spreading species. The concept for the park is thought to have been influenced both by nineteenth century English landscapes and National Parks in the United States.
In 1929, the Board reported that 'a very large number of deciduous and other trees have been planted and most of these are growing well.' Additional trees were planted at the Park in the early to mid 1930s including a number of elms at the base of the dam wall which were removed from Sydney Road, Brunswick when new electric lights were installed. Parts of the catchment were destroyed in the 1939 bushfires and were replanted in the 1940s under the leadership of E G Ritchie, who was a strong supporter of forest conservation. From the 1940s to the 1960s, two rotundas, a bridge over the lily pond, stone edging and pathways, the rose steps, and a sundial were constructed. Importantly for the increased use and ownership of motor cars in the age of the 'day trip', was the construction of a large carpark.
Changes to the Maroondah system (1970s - mid 1980s)
In the 1970s the Sugarloaf Reservoir was constructed. From 1978 water from the Maroondah reservoir still flowed into the upper section of the Maroondah aqueduct but was redirected to the Sugarloaf reservoir via pump at Yering Gorge. Further changes took place in the mid 1980s including the extension of the bottom outlet system of the Maroondah dam and construction of a new valve house on the Watts River. The width of the spillway channel was also increased to allow for greater flood flows. The final stage of works stabilised the dam structure with a series of vertical cable anchors within the dam wall.KEY REFERENCES USED TO PREPARE ASSESSMENT

MAROONDAH WATER SUPPLY SYSTEM (UPPER AND CENTRAL SECTIONS) - Permit Exemption PolicyPreambleThe purpose of the Permit Policy is to assist when considering or making decisions regarding works to a registered place. It is recommended that any proposed works be discussed with an officer of Heritage Victoria prior to making a permit application. Discussing proposed works will assist in answering questions the owner may have and aid any decisions regarding works to the place.
The extent of registration of the Maroondah Water Supply System in the Victorian Heritage Register affects the whole place shown on Diagrams 2381A, 2381B and 2381C including but not limited to the Watts River catchment, the location of the former township of Fernshaw, including oak and redwood trees, the Maroondah dam and reservoir, outlet tower, two valve houses, caretakers huts, weirs and their associated picnic areas, tunnels, aqueduct, siphons, pipes, drains and scours from the south western edge of the Yarra Ranges to Diamond Creek, Junction Basin at Preston and the Plenty River Pipe Bridge at Greensborough. It also includes Maroondah Reservoir Park comprising roads and paths, two rotundas, fences and gates and extensive tree planting and gardens. Under the Heritage Act 1995 a person must not remove or demolish, damage or despoil, develop or alter or excavate, relocate or disturb the position of any part of a registered place or object without approval. It is acknowledged, however, that alterations and other works may be required to keep places and objects in good repair and adapt them for use into the future.
If a person wishes to undertake works or activities in relation to a registered place or registered object, they must apply to the Executive Director, Heritage Victoria for a permit. The purpose of a permit is to enable appropriate change to a place and to effectively manage adverse impacts on the cultural heritage significance of a place as a consequence of change. If an owner is uncertain whether a heritage permit is required, it is recommended that Heritage Victoria be contacted.
Permits are required for anything which alters the place or object, unless a permit exemption is granted. Permit exemptions usually cover routine maintenance and upkeep issues faced by owners as well as minor works or works to the elements of the place or object that are not significant. They may include appropriate works that are specified in a conservation management plan. Permit exemptions can be granted at the time of registration (under s.42 of the Heritage Act) or after registration (under s.66 of the Heritage Act).
It should be noted that the addition of new buildings to the registered place, as well as alterations to the interior and exterior of existing buildings requires a permit, unless a specific permit exemption is granted.
