As one of the country’s most diverse geographical regions, Tasmania poses unique challenges when it comes to the measurement and control of water supply to properties across the state.

We partnered with the state’s local authority, TasWater, to deliver an industry-leading rollout of more than 45,000 iPerl smart meters to improve the accuracy and efficiency of their readings.

With more than five years in the making, this project is Australia’s largest rollout of smart metering technology—its success proving the technical capability of the iPerl while creating value for our clients and the community.

"The iPerl drive-by system is four times faster than reading AMR meters, which are four times faster than the traditional mechanical meters. This means a 4 x 4 efficiency improvement."

Robert Cameron – Senior Project Manager, TasWater

Building a business case for the iPerl

When TasWater’s old mechanical meters began to show signs of wear, their team saw an opportunity to upgrade their system.

The project and its implementation were supported by a robust business case and assessment made by an independent consultant on behalf of TasWater. The assessment considered a variety of alternative technologies through a process of research, trial, and testing.

Through this process, it was determined that a digital static meter would provide the greatest functionality and return on investment for the authority.

Static meters are linear, offering the capability to capture low flows while providing visibility of data logs and water consumption. Available in the same Australian standard length as their current meters and offering a digital display for easy configuration—the iPerl stacked up to be the meter that enabled the greatest improvements on the current system.

Trials without error

To support the business case for the iPerl, TasWater’s board required three trials to be performed:

Trial 1

The first trial involved installing 400 meters by the TasWater office. This trial yielded results that proved the capability of the iPerl when it came to low flow measurement. By using the iPerl, the team was able to observe the revenue gained by capturing usage that otherwise went unnoticed in the current system.

Trial 2

The second trial involved installing 4000 meters in Port Sorrel, Hawley. This involved residential homes, and a test of the iPerl’s drive-by reading capabilities. The trial proved to be successful, as the drive-by reading drastically sped up the reading process while providing accurate and easy to access measurement via the data logger.

Trial 3

The third trial involved ensuring that the iPerl could be integrated with the existing TasWater meters. This was important—as meters of different sizes would be rolled out at separate times. The meter had to provide readings alongside existing meters, while being compatible with TasWater’s current billing system. Both these requirements were satisfied by the iPerl.

The three trials completed by the third-party assessors formed the basis of the project tender. This tender was awarded to Bermad Water Technologies due to the technical superiority of the product, the positive factors observed during the trial, and our ability to provide onsite support throughout the rollout of the meters.

The iPerl

The iPerl smart water meter from Sensus uses intelligent and responsive data architecture that turns the smart grid concept into a reality. The meter offers an extended battery life and provides robust billing and measuring support for authorities.

With benchmark accuracy and low flow capture, the iPerl reduces costs and creates operational transparency. This meter represents a data end-point that replaces the traditional meter, captures and communicates network status and consumption data remotely and in real-time, while continuously monitoring system integrity.

Wentworth to Broken Hill water supply pipeline

September 2018

We partnered with Water NSW to successfully supply, deliver and consult on our range of air release valves for the Wentworth to Broken Hill pipeline project.

Valued at nearly $500 million, and spanning 270km, the project is one of the region’s largest—the Bermad team worked to supply a range of air release valves to help secure long-term water supply for the community.

A pipeline that invests in the community.

The pipeline began works as of February 2018 and runs along the length of the state between Wentworth and Broken Hill. The 270km length pipeline will allow raw water to be sourced near the Murray River, and is being constructed underground following the Silver City Highway corridor to Broken Hill.

The project aims to secure water supply for the region, and according to WaterNSW, will provide immediate benefits to both the Broken Hill and Wentworth communities. Early estimates indicate that spending in the local community could be between $30 to $42 million during the construction of the pipeline (WaterNSW).

“The pipeline will supply up to 37.4 megalitres of a peak daily demand of raw water and provide more than 150 local jobs as well as the sourcing of project materials and other support logistics from regional providers.”

Project specifications

The pipeline is built from 270km of 762mm Australian rolled steel, and includes surface infrastructure that consists of:

  • A water intake pump station by the Murray River.
  • Two transfer pumping stations.
  • A bulk water pump station alongside a photovoltaic power (solar) generation system and a bulk water storage dam.

The pipeline and associated infrastructure also provides drinking water to both the Wentworth and Broken Hill communities. 20,827 pipes delivered to site via 2315 semi-trailers from Victoria and Western Australia to the outback mining area.

20,827 pipes delivered and lined up ready to be connected and implemented into the ground.

The project was installed and constructed in record time, and seven months in, there has been amazing progress on the total solution.

Bermad Water Technologies were the chosen supplier for more than 450 DN100 PN16 and PN35 air valves for the project. Our range of CSA Fox RFP and Fox AS air release valves were selected to maximise pipe flows and minimise the effect of water hammer along the lengthy pipe network.

Bermad’s range of CSA air release valves were selected due to the following reasons:

  • Product approval and compliance with AS4956 standards.
  • Proven on the field for major projects in large numbers with CSA’s renowned reliability
  • Ability to supply a huge project within a tight timeline with testing for assurance of in field performance.
  • Ability to provide PN35 rated valves to meet engineering performance requirements.
  • Ability to provide the correct level of surge protection using Fox-RFP and Fox-AS surge prevention air valves.

“We really appreciated Bermad’s support in ensuring the air release valves were delivered to the site on time and in full. We have tested over 170km of the pipeline with the air valves running, with every single one passing the pressure test —which is impressive due to the length of the application.”
