Work has begun on a new stormwater pump station behind the levee at Murwillumbah (Brothers) Leagues Club.

The $1.626 million flood mitigation project is one of several being delivered in the Tweed Local Government Area as part of the Australian Government-funded Northern Rivers Recovery and Resilience Program (NRRRP) following the devastating floods of February and March 2022.

It is being undertaken by Tweed Shire Council in partnership with the National Emergency Management Agency (NEMA), the Reconstruction Authority (RA) and the NSW Department of Climate Change, Energy, the Environment and Water (DCCEEW).

“This stormwater pump station was a vital component of Council’s flood mitigation strategy for Murwillumbah and aims to reduce the impact of stormwater flooding in the area,” said Tweed Shire Council Mayor Chris Cherry.

“The pump station will not eliminate all flooding but it will reduce the frequency and magnitude of nuisance flooding due to storm events. While we can’t stop flooding from occurring, the pumps will significantly improve drainage of the area following a rain event, helping to reduce the impact of flooding on local residents and Brothers Leagues Club in the future.”

Construction of the pump station started in early May and is expected to take about three months to complete, weather permitting. Two new pumps will be installed, standing approximately two metres tall. Combined, they will be able to move almost 1000 litres of stormwater per second at full speed — the equivalent of filling up over six bathtubs of water per second.

“This project is an excellent example of how government funding can support communities in undertaking necessary steps to improve flood protection following the devastating 2022 flood events,” said Member for Richmond Justine Elliot.

“The NRRRP is delivering real projects in the Tweed which are local priorities and will ensure communities like Murwillumbah are in a better position to recover from future severe weather events.”

Under the NRRRP, $6.67 million has been awarded for several other projects supported by an additional $2 million from the RA.

These projects are:

  • Wharf Street pump station upgrade
  • Lavender Creek pump station upgrade
  • New pump system within east Murwillumbah levee
  • Detailed evacuation procedures
  • Alma Street modification
  • Earthworks across Lot 4 on Quarry Road and modification of Condong Creek.

Bee Hotels Can Help Native Pollinators Recover in the Wake of Climate-Fueled Wildfires: Study

Wild pollinator populations are declining all over the world, with increasingly severe climate change-fueled wildfires threatening their survival. These intense wildfires are also putting long-term ecosystem health and biodiversity at risk. Bee hotels are artificial nesting structures that have been specially designed to house cavity-nesting species. Often placed in backyards or gardens, they provide safe […]

ABB receives EPD status for gearless mill drive ring motor

ABB receives EPD status for gearless mill drive ring motor

ABB has gained Environmental Product Declaration (EPD) status for its Gearless Mill Drive (GMD) ring motor — technology used to drive large grinding mills in the mining industry.

An EPD is a standardised document that provides detailed information about the environmental impact of a product throughout its life cycle. Based on a comprehensive Life Cycle Assessment (LCA) study, the EPD highlights ABB’s commitment to transparency, environmental responsibility and supporting customers in making informed decisions on sustainability in their supply chains.

ABB analysed the environmental impact of a ring motor across its entire life cycle from supply chain and production to usage and end-of-life disposal. The study was conducted for a ring motor of a semi-autogenous grinding (SAG) mill with an installed power of 24 MW and was based on a reference service life of 25 years.

“Sustainability is at the core of our purpose at ABB, influencing how we operate and innovate for customers,” said Andrea Quinta, Sustainability Specialist at ABB. “By earning the Environmental Product Declaration for our ring motor, we emphasise our environmental stewardship and industry leadership for this technology. We adhered to the highest standards throughout this process, as we do in the ABB Ring Motor factory every day. This recognition highlights to the mining industry what they are bringing into their own operations when they work with ABB.”

The comprehensive LCA was conducted at ABB’s factory in Bilbao, Spain, and was externally verified and published in accordance with international standards ISO 14025 and ISO 14040/14044. It will remain valid for five years.

The ring motor, a key component of the GMD, is a drive system without any gears where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. It optimises grinding applications in the minerals and mining industries by enabling variable-speed operation, leading to energy and cost savings.
