“The biggest benefit of the enterprise agreement is the agility you have with AVEVA PI System software components. So, if there are proof of concept projects or training needs, you can stand up the technology and give something a go very easily.”
Anthony O’Flaherty, Manager of Data and Analytics at TasWater
TasWater also provides safe drinking water to all of Tasmania
Across 29 separate jurisdictions that use different control systems from multiple vendors. AVEVA PI System gives TasWater a single source of truth, so it gets one comprehensive view of operations across all those control systems.
Without that unified data, it used to take an engineer up to one day every week to monitor critical control points (CCP). But now AVEVA PI System does it automatically—in just 15 minutes. Engineers use the time they’ve saved to optimize plants, solve problems and work more closely with operators. Now TasWater proactively identifies 100% of potential CCP breach conditions, helping it comply with the Australian Drinking Water Guidelines.
Goals
- Meet increasingly stringent water quality regulatory requirements
- Gain early notification of potential breach conditions
- Automate, systematize and standardize reporting and setpoints
Challenge
- Monitor critical control points (CCPs) in water treatment plants across 12 different SCADA instances over 70 drinking water systems and 6,266kms of water mains
Solution
Results
Skilled and experienced engineers and scientists are freed up to solve problems and effect solutions, not find data
- Breach detection improved from <10% potential breaches detected to 100% of potential breaches detected
- Weekly reporting time reduced from one day to 15 minutes
- Identified underlying issues and allowed them to be rectified
TasWater, Tasmania’s primary water and sewage utility
Manages one of the oldest sewer networks in Australia. After a sewage spill infiltrated a nature reserve in 2017, TasWater dedicated itself to finding a way to catch blockages and spills more quickly. In collaboration with Nukon, an AVEVA, partner, TasWater launched a proof of concept (POC) trial to explore what data and IIoT technology can do for the water industry. TasWater’s data approach has reduced costs and time spent analyzing data, freeing its scientists to implement more efficient and safer methods of investigating spills and leaks.
