It also delivers planning and infrastructure programs for housing and jobs both in new land release areas and urban renewal precincts. This includes developing zoning and development controls through Local Environmental Plans (LEPs) to guide planning decisions locally. DPIE’s Water Group leads and coordinates metropolitan water planning for Greater Sydney. They are not represented at the symposium as they are currently finalising the Draft Greater Sydney Water Strategy for public consultation. WaterNSW manages the dams that collect rainwater run-off from river catchments to the south and west of Sydney. The water is stored and transported via a network of rivers, pipes and canals to Sydney Water. WaterNSW is also responsible for protecting the health of Greater Sydney’s drinking water catchments. Sydney Water operates the nine water filtration plants that treat the raw water provided by WaterNSW, and delivers the treated drinking water to customers in the Greater Sydney, Blue Mountains and Illawarra. Sydney Water also collects and treats wastewater, provides recycled water services to some areas and manages some major stormwater infrastructure. Sydney Water is also responsible for water supply planning in line with numerous drivers, such as growth, climate change and environmental performance. Note: Private water utilities licensed under the Water Industry Competition Act 2006 provide water services to a number of communities in Greater Sydney, often using supply solutions that include recycled water. 5 How is Sydney Water working to provide a secure water supply for the growing Wollondilly region? 19 May 2021 Acknowledgement of Country Sydney Water respectfully acknowledges the traditional custodians of the land and waters on which we work, live and learn.

  • Professionals Australia's Response on Behalf of Members in Relation to The
    Professionals Australia’s response on behalf of members in relation to the proposed restructure PA met with engineers who work in the Engineering Division on two occasions at WNSW Parramatta offices with members dialling-in from regional NSW. PA encouraged members to put forward their professional views on the proposed restructure on whether it addressed existing problems. PA has received some very detailed responses from our members. It is clear there is a high level of concern that the restructure will have undesired impacts on both employees and the functions of Engineering. Many members have taken the opportunity to respond directly to the WNSW email address set up for feedback. This submission does not repeat those comments. This submission is concerned with the first order issue – Does the restructure enhance the undertaking of engineering functions by WaterNSW or not? The next level of concerns which appear to be the main focus of the input provided via the WNSW email are the detail of position descriptions and the arrangements for filling the structure. We understand such matters have also attracted a large number of comments and concerns from members. However, those issues arise only when the first order issue is satisfied. The focus of this submission is whether the restructure has accurately identified the deficiencies and whether the proposal will address those deficiencies. What can a restructure address? A restructure can address issues such as resourcing levels, specific function focus and functional alignment. It cannot address issues caused by dysfunctional organisational behaviour, lack of effective processes, etc. Does the restructure enhance engineering functions at WNSW? The view of WNSW engineers is that overall the restructure will not result in the enhanced performance of the engineering functions required by WNSW.

    In the beginning Sydney’s first water supply from the time of its settlement Sydney Water in 1788 was the little stream that wound its way from near A day tour of the water supply Hyde Park through the centre of the town into Sydney Cove. It became known as the Tank Stream. By 1811 it dams south of Sydney was hardly fit for drinking. Water was then drawn from wells or carted from a creek running into Rushcutter’s Bay. The Tank Stream was still the main water supply until 1826. In this whole-day tour by car you will see the major dams, canals and pipelines that provide water to Sydney. Some of these works still in use were built around 1880. The round trip tour from Sydney is around 350 km., all on good roads and motorway. The tour is through attractive countryside south Engines at Botany Pumping Station (demolished) of Sydney, and there are good picnic areas and playgrounds at the dam sites. source of supply.

  • Dam Failure Warning and Evacuation Planning in New South Wales
    DAM FAILURE WARNING AND EVACUATION PLANNING IN NEW SOUTH WALES: RECENT PROGRESS AND THE FORWARD PROGRAM Chas Keys State Planning Co-ordinator NSW State Emergency Service Planning for the kinds of floods which would follow the failure of large water storage dams is relatively new in Australia. In New South Wales it began in the late 1980s following the realisation, based on improved scientific comprehension of severe weather and flood events, that some dams had spillways which were incapable of safely passing very severe floods. For a time progress was slow as far as plan development was concerned but over the past year or two it has picked up significantly. Several plans, under preparation for a considerable length of time, have been completed to final draft stage and a number of new ones have been started. At the same time the ‘rules’ by which the planning is being done and on which responses to dam-failure would be based have been fine-tuned. Moreover, the shape of the future planning program and associated activities can be seen with increasing clarity. Until quite recently the State Emergency Service was, like most emergency management organisations in this country, much more oriented towards responding to emergencies than in preparing to respond to them. Planning, as a consequence, was not given a high priority and there were few trained planners appointed to the organisation and few resources allocated to them. Activities involving planning for floods were in their infancy and planning expertise was lacking. Accordingly, the organisation was not well placed to react quickly when, in the mid-1980s, the PMP/PMF revisions made it clear that several of the state’s major water storage dams had inadequate spillway capacities and were in a few cases quite dangerously underdesigned in terms of their security during significant flood events.

  • History of Sydney Water
    The history of Sydney Water Since the earliest days of European settlement, providing adequate water and sewerage services for Sydney’s population has been a constant challenge. Sydney Water and its predecessor, the Metropolitan Water Sewerage and Drainage Board, has had a rich and colourful history. This history reflects the development and growth of Sydney itself. Over the past 200 years, Sydney’s unreliable rainfall has led to the development of one of the largest per capita water supplies in the world. A truly reliable water supply was not achieved until the early 1960s after constructing Warragamba Dam. By the end of the 20th Century, despite more efficient water use, Sydney once again faced the prospect of a water shortage due to population growth and unreliable rainfall patterns. In response to this, the NSW Government, including Sydney Water, started an ambitious program to secure Sydney’s water supplies. A mix of options has been being used including water from our dams, desalination, wastewater recycling and water efficiency. Timeline 1700s 1788 – 1826 Sydney was chosen as the location for the first European settlement in Australia, in part due to its outstanding harbour and the availability of fresh water from the Tank Stream. The Tank Stream remained Sydney’s main water source for 40 years. However, pollution rapidly became a problem. A painting by J. Skinner Prout of the Tank Stream in the 1840s 1800s 1880 Legislation was passed under Sir Henry Parkes, as Premier, which constitutes the Board of Water Supply and Sewerage. 1826 The Tank Stream was abandoned as a water supply because of pollution from rubbish, sewage and runoff from local businesses like piggeries.

  • 2. Land and Water Management Issues in the Lower Shoalhaven River Catchment
    Case Study: 2. Land and Water Management Issues in the Lower Shoalhaven River Catchment What are Some of the Land and Water Management Issues in the Shoalhaven River Catchment? Land and water within a catchment is often managed for multiple benefits that might include such things as agricultural production, biodiversity conservation, good water quality, soil health, flood mitigation and for supporting human lifestyles and living places. Quite often there are competing interests in land use and water management outcomes. For example, an irrigator may wish to extract more water from the river in times of drought, whereas a fisher would want this water to remain in the river for wetland health and fish survival. Thus there needs to be cooperation between individuals, groups and governments to balance often opposing social, economic and environmental needs. Sometimes people get things wrong and past practices and approaches need to be stopped, refined or modified. The Shoalhaven River Catchment has many land and water management issues that are typical of other catchments and estuaries along the NSW coast. However, these issues have specific details and management options that are unique to the Shoalhaven River. According to plans such as the Shoalhaven River Estuary Management Plan, the main land and water management issues in the Lower Shoalhaven Catchment are: . increased urban and industrial development; . flood mitigation works; . acid sulfate soils; . streambank erosion; . specific pollution sources; Industry alongside the Shoalhaven River (starch plant), source: OceanWatch Australia . catchment flows; . barriers to fish passage; and . the possible impacts of climate change. How are the Land and Water Issues in the Catchment Managed? 1.
