Two Queensland councils* have opted for Australian-manufactured screening technology to protect the efficiency of their wastewater treatment plants (WWTPs).
In choosing horizontal in-channel rotary drum screening technology engineered by CST Wastewater Solutions, the councils also sought to curtail risks of process and environmental spills from blockages.
CST Wastewater Solutions’ full stainless steel drum technology — with fine pre-screening down to 200 µm — provides a first line of defence against detritus in municipal and industrial wastewater streams entering vital water treatment processes within the WWTPs involved.
The company explained that an integral part of its new, locally manufactured rotary drum screens and auger extractors is industry-best screening, which provides 50% finer apertures for greater waste-solids extraction and recovery.
Drum screens reduce maintenance costs and extend equipment life by preventing clogging and build-up of solids, and prevent the formation of filtrate crusting on the primary clarifier, which is essential for the treatment plant to operate optimally.
CST Wastewater Solutions Managing Director Michael Bambridge said the in-channel (or in-tank) drum screens are custom-engineered for unique local conditions, including widely varying flow rates and inflow content. He added that the systems also recognise the need to cater to municipal and industrial companies that cannot afford to have large in-house engineering and maintenance teams.
One of the latest Queensland installations involved twin screw screens, constructed from full 316 grade stainless steel, with each screen capable of handling 230 L of inflow a second. The Australian-manufactured screens replaced imported screens that were less than 10 years old.
“The second twin-screen installation, with fine drum screening down to 3 mm and 400 L/s capacity, was installed by a major utility operating in a marine environment that was impressed with the performance and durability of existing CST screening technology,” Bambridge said.
“Existing high performance, low maintenance and, importantly, the prompt availability of local service expertise were among the prime reasons for this major authority introducing further CST technologies to maintain and enhance the performance of a WWTP operating in a marine environment,” he added.
CST has drum screens with holes as fine as 2 mm that have been operating for more than 10 years in Queensland.
Bambridge said that rather than opting for one-size-fits-all imported technologies — with potential downtime and supply chain issues when they need service — many local authorities and industrial WWTP operators value the availability of local engineering expertise.
“Good local service is an essential complement to good equipment. Imported equipment is always at the mercy of supply chain delays and cost. Such equipment could be useless the first time it broke down, until it is repaired,” he said.
“Then, both municipal and industrial organisations face the risk of non-compliance of licence conditions and downstream blocking, flooding, production interruptions, and environmental and groundwater hazards.”
CST has been progressively moving towards Australian manufacturing since COVID affected supply chains. It has now achieved full Australian design and manufacture of the following ranges:
Internally fed rotary drums — Model RDs
In-channel horizontal rotary drum — Model FS
Screw screens and associated equipment — Model SF

Two Years, $380+ Million: Lessons Learned from USAID’s Climate Finance for Development Accelerator
At COP26, USAID’s Climate Finance for Development Accelerator (CFDA) launched with a goal of mobilizing $2.5 billion in public and private investment for climate by 2030. In two years of operations, CFDA has mobilized $380.7 million in sustainable investments and worked with partners to strengthen local ecosystems in over 60 countries. This blog outlines some of CFDA’s biggest lessons learned for catalyzing investment in the climate finance space.
Bridging the Adaptation Finance Gap Across Africa
Climate finance was a popular topic of conversation for governments, donors, and other stakeholders at COP29. In Africa, limited capacity and resources to develop proposals coupled with complex proposal requirements and high competition for limited funds have resulted in only a fraction of the available climate adaptation funding reaching the region. The African Adaptation Initiative, launched at COP21 and supported by USAID’s Climate Adaptation Support Activity, is working to bridge this climate finance gap.
Empowering Female Farmers: Introducing Solar Water Pumps in Rural Senegal
At COP29, one of the thematic days was focused on food, agriculture, and water in recognition that these sectors are both threatened by climate change and have a role to play in providing solutions to the crisis. USAID’s Scaling Up Renewable Energy Senegal program works at the intersection of agriculture, water, and energy through its efforts to expand access to solar solutions that increase the productivity of small businesses and enhance the livelihoods of rural communities.
Accessible Data Makes Renewable Energy Projects Possible Worldwide
Energy and science, technology, innovation, and digitalization were two of the thematic days at COP29. One example of how digital technologies can promote clean energy and address the climate crisis is the USAID-National Renewable Energy Laboratory Partnership’s Renewable Energy Data Explore. This geospatial analysis tool provides free global renewable energy resource data to inform policy, investment, and deployment decisions for solar, wind, and other energy resources.
Beyond Blueprints: Accelerate Implementation Now
USAID’s Comprehensive Action for Climate Change Initiative (CACCI) was launched at COP26 with the goal of identifying promising mitigation and adaptation investment opportunities with private sector partners to help countries meet their climate commitments and strengthen their climate resilience. Since then, CACCI has made progress on several fronts, including by increasing climate policy ambition, mobilizing the private sector, enhancing accountability and transparency, and bridging the gap between intention and results.
Tracking Impact: A Look Back at Past COP Initiatives Ahead of COP29
The annual COP is a chance to take stock of what progress has been made to meet climate goals. At previous COPs, USAID has launched climate initiatives related to climate finance, resilience, climate risk management, and more. This roundup of recent Climatelinks blogs highlights the progress driven by some of these initiatives.
New Resources
USAID 2024 Climate Monitoring, Evaluation, and Learning (MEL) Series
USAID programs with climate change benefits are required to report against a set of standard indicators. The 2024 Climate MEL webinar series was developed to improve reporting on these indicators. USAID staff and implementing partners are encouraged to review this series to explore key climate reporting topics, gain knowledge to inform annual reporting processes, and learn tips and tricks for navigating reporting and ensuring the quality of data in technical areas.
Sustainable Banking Alliance Learning Report: Engaging Local Financial Institutions to Integrate Climate Finance Best Practices
At COP27, USAID announced the launch of the Sustainable Banking Alliance (SBA), an initiative that partners with banks and microfinanciers to increase access to climate finance, promote the integration of climate finance best practices, and increase climate investments. This “how-to guide” builds on lessons learned from SBA initiatives in Colombia and Egypt and provides guidance to USAID, specifically to Mission staff, on how to engage with financial institutions to integrate climate finance best practices.
Investing in Resilience: Blue Carbon Ecosystems, Communities, and Finance for the Indo-Pacific
“Blue carbon” is carbon stored by coastal and marine ecosystems, such as mangroves, seagrass beds, coastal wetlands and marshes, tidal flats, and by marine organisms themselves. USAID’s Investing in Resilience report brings together evidence and analyses that can help USAID Mission staff, partners, host country governments, and communities advance blue carbon initiatives in the Indo-Pacific region.
Livelihood-Focused Climate Risk Assessment: Stress Testing Livelihood Options in the World’s Largest Terrestrial Transboundary Conservation Area
Climate change impacts are already being felt across the Kavango Zambezi (KAZA) Transfrontier Conservation Area. In recent years, residents have reported significant impacts to their livelihoods due to a combination of decreased rainfall, higher incidences of drought, changes in the timing of seasons, more hotter days and heat waves, and dwindling supplies of water. This Climate Risk Assessment seeks to answer how and in what ways a changing climate limits progress towards diversifying livelihoods for KAZA’s resident communities.
Climate Risk Management Spotlight
Climate Risk Management Resources and Training
Climate Risk Management (CRM) enhances the resilience and sustainability of USAID’s initiatives. By systematically assessing, addressing, and adaptively managing climate risks, CRM ensures effective use of U.S. taxpayer dollars. To promote CRM, USAID has produced a variety of resources and online trainings.
