CASE STUDY Project Summary Organization: South Australia Water Solution: Water and Wastewater Location: Adelaide, South Australia Project Objective: • Predict demand and optimization of water across the network • Improve analytical and decision-making capabilities regarding new infrastructure and reduce operational costs • Converge IT and operational data for short and long term planning Products used: Amulet Fast Facts • The Adelaide area is comprised of sixteen water supply zones, six major water treatment plants, and nine reservoirs. • There are 26,000 kilometers of water mains in the state, of which 8,900 kilometers are in metropolitan Adelaide. • A 25-year historical database of weather was used to predict long-term planning. ROI • Predict short-term hourly and daily demand levels and long-term capital planning in seconds • Saved AUD $3 million in energy costs in the 2013-2014 financial year • Further AUD $400,000 saved in network expenditure over six months • Reduced reaction times South Australia Water Saves AUD 3 Million in Energy Costs Using Bentley Software Amulet Provides Invaluable Forecast Data to Water Authority Regarding Water Usage and Movement Transforming the Way Water Is Distributed South Australia is the driest state in the driest inhabited continent on earth. In fact, only 4 percent of the province receives more than 500 millimeters of rain each year. The River Murray, which flows for over 2,500 kilometers, is South Australia’s only major river. Amulet was selected for the role of operational intelligence platform for its real-time ability to connect and capture data from a wide variety of sources, perform complicated calculations and analysis, and for its impressive range of visualization components. Adelaide and the surrounding area can experience prolonged periods of drought, the last of which prompted the building of a high capacity desalination plant and a north-south interconnecting pipeline within South Australia that, for the first time, allowed South Australia Water (SA Water) to distribute water almost anywhere in its network at any time in previously unachievable ways. What it couldn’t achieve successfully was predicting demand and optimizing water movement accordingly. This new desalination plant and the ongoing investment in telemetry equipment caused SA Water to look for more benefits, including increased analytical and decision-making capabilities to enhance the management of its network and optimize water usage. Bentley’s Amulet was chosen as the commercial operational intelligence platform. It consisted of three separate systems (rolled out in stages), and provided SA Water with the ability to combine IT and operational data to predict water usage, distribution, and electricity usage. Three separate decision support tools were deployed in stages: the Demand Forecasting tool, the Distribution Optimization tool, and the Energy Portfolio Management (EPM) system. These combined systems saved SA Water AUD 3 million in energy related costs by predicting tariff increases and moving water accordingly. Data collected from the operational side was previously stored in SCADA systems and fed to an OSIsoft PI system, which was then accessed through Amulet. Real-time monitored sensor data is transmitted from the reservoirs, water treatment plants, valves, flow meters, and pumps spread across the extensive pipeline network. To maximize optimization, multiple sources of data from internal and third-party information systems was combined to aid predictions for the Demand Forecasting tool. IT-OT Convergence to Maximize Performance The Value of Forecasting Demand and Usage One of the main objectives for SA Water was pulling information from both the operational side and the information technology side in real time. Bringing them together has resulted in huge benefits, including improving performance, enhancing the understanding of interrelationships, and enabling better decision making. The Demand Forecasting tool is a model that predicts demand in network zones at different time frames specified by the user. It predicts short- and long-term demand – from hourly and daily forecasts up to annual strategic long-term capital forecasts. To make smarter predictions against actual water levels, more data from IT needed to be made available, Operational data from the network is combined in real time with climate, energy, cost, and population data and

“The Amulet tools have enabled us to develop operational analytics, dashboards, and reports, which help us effectively plan, monitor and control our integrated water supply system.” — Steve McMichael, Manager Network & Production Planning, South Australia Water Find out about Bentley at: www.bentley.com Contact Bentley 1-800-BENTLEY (1-800-236-8539) Outside the US +1 610-458-5000 Global Office Listings www.bentley.com/contact especially when considering the many variables SA Water had to take into account, such as: • water restrictions, usage, and demand patterns; and order to make the most of...
