Challenge

The operator faced a growing concern over water loss across their diverse portfolio of water schemes, ranging from 5 to 100 kilometres. These schemes, predominantly featuring non-metallic water mains, presented unique challenges for leak detection due to sound propagation limitations and complex configurations, including “rider” mains. Additionally, customer-side leaks posed a challenge as meters weren’t read, and consumption wasn’t billed volumetrically.

Solution

Recognising the need for specialised expertise, the operator engaged Aqua Analytics to conduct a thorough water loss investigation across their various schemes. Aqua Analytics’ personalised approach involved:

Aqua Analytics deployed a team of leak detection specialists who are experienced in working with non-metallic pipe networks. They utilised specialised acoustic equipment and techniques specifically designed to overcome the challenges of sound propagation in these materials.

The project encompassed a comprehensive investigation of each water scheme, including:

Boundary Valve Assessment: Thorough inspection and testing of boundary valves to identify leaks and ensure proper isolation capabilities.
Trunk Main Leak Detection: Systematic leak detection on trunk mains using advanced acoustic technologies.
Appurtenance Inspection: Examine all accessible appurtenances, such as hydrants and valves, to identify leaks or potential failure points.
Customer Side Leak Detection: Investigation of leaks on customer properties despite the absence of volumetric billing.

Challenge

Due to an unidentified water leak, the precinct’s body corporate faced alarmingly high water bills, reaching a staggering $10,000 per day. The extensive private water network, consisting of pipes, hydrants, meters, and submeters, made locating the leak source a complex and urgent.

Solution

Aqua Analytics was engaged to investigate the source of the massive water loss. Their solution involved a combination of technical expertise and smart technology:

Smart Metering Loggers: Aqua Analytics strategically installed smart metering loggers, including Captis Lite devices, onto the main water meters throughout the precinct. These loggers provided real-time data on water consumption patterns, enabling Aqua Analytics to pinpoint areas of excessive water usage.
Data Analysis and Anomaly Detection: The smart loggers transmitted consumption data to Aqua Analytics' cloud-based platform, which was analysed for anomalies. A significant spike in water usage was detected at one specific meter, indicating a potential leak in that network section.
Skilled Field Investigation: A team of Aqua Analytics' experienced technicians was dispatched to the site to investigate the identified meter and its surrounding infrastructure further. Utilising their expertise and specialised equipment, they thoroughly inspected the area.
Leak Identification and Repair: The investigation revealed a DN100 pipe that had been left open-ended, discharging thousands of kilolitres of water directly into a nearby waterway. The body corporate was immediately notified, and prompt repairs were undertaken to seal the pipe.

Results

Dramatic Reduction in Water Usage: Following the repair, the precinct's water consumption plummeted from approximately 2,239 kL per day to 85 kL per day, saving a substantial amount of water and money.
Immediate Cost Savings: Eliminating the $10,000 per day leak resulted in significant cost savings for the body corporate, directly impacting its bottom line.
Improved Resource Efficiency: The precinct substantially reduced its water footprint by addressing the leak, contributing to a more sustainable operation.
Enhanced Asset Management: The project highlighted the importance of proactive leak detection and efficient water management for commercial properties with extensive private water networks.

Client Benefits

Cost Recovery: The rapid identification and repair of the leak allowed the body corporate to recoup the significant financial losses incurred due to the water waste. Sustainable Practices: By addressing the leak, the precinct significantly reduced its environmental impact and demonstrated a responsible water resource management commitment.
Improved Reputation: The proactive approach to water conservation enhanced the precinct's reputation as a responsible corporate citizen.
