The Rouse Hill Bus Depot is more than just a transport hub—it’s a benchmark in sustainable infrastructure, designed to enhance operational efficiency while minimising environmental impact.
A key player in this transformation was Deboke Engineering Consultants, a Sydney-based multidisciplinary firm specialising in civil, structural, stormwater, and remedial engineering.
Led by Directors Andrew Arida, Charbel Felfleh, and Joseph Dagher, Deboke’s expertise was instrumental in ensuring that the depot’s engineering solutions met sustainability targets while enhancing long-term durability and efficiency.
“The Rouse Hill Bus Depot was designed with sustainability at its core, integrating advanced stormwater management and rainwater harvesting for bus washing,” explains Arida and Dagher. “The project also incorporated Water Sensitive Urban Design (WSUD) principles, ensuring that stormwater quality and reuse were prioritised to minimise environmental impact and enhance operational efficiency.”
From the outset, Deboke’s role was critical in designing systems that balanced sustainability with the depot’s high-traffic demands. Given the site’s large-scale hardstand areas and continuous vehicular movement,
the team implemented a range of stormwater treatment and erosion control strategies.
A collaboration with Ocean Protect resulted in a custom-engineered stormwater filtration system that captures and treats pollutants such as Total Suspended Solids (TSS), Total Nitrogen (TN), Total Phosphorus (TP), and Gross Pollutants (GP) before releasing water into public infrastructure and natural waterways.
“Given the nature of the site, it was critical to address contaminants entering the stormwater system,” explains Arida and Dagher. “This system ensures that clean water exits the site, aligning with WSUD strategies to enhance environmental sustainability.”
In addition to water management, Deboke Engineering Consultants focused on using low-maintenance, highly durable materials to reduce the environmental impact across the depot’s lifecycle. “Additionally, sustainable construction methods, such as prefabrication where feasible, helped minimise waste and construction time,” says Felfleh.
This combination of smart material choices, efficient engineering solutions, and sustainability-driven construction methodologies positioned the depot as an example of environmentally responsible transport infrastructure.
A key focus of the project was minimising carbon emissions and ensuring the depot’s long-term resilience. Deboke achieved this through a rainwater tank reuse system, reducing reliance on external water sources.
“Coupled with the rainwater tank reuse system, this creates a highly efficient mechanism for controlling water quality in new developments, while simultaneously reducing operational costs and environmental impact,” Arida and Dagher notes.
Beyond the depot’s immediate needs, Deboke also integrated future-proofing measures to ensure that the site could adapt to changing transport technologies and evolving sustainability standards. This included designing the stormwater and civil infrastructure to accommodate future electrification of the bus fleet, which will further reduce emissions over time.
The Rouse Hill Bus Depot is just one of many complex engineering projects Deboke Engineering Consultants is currently undertaking. Their portfolio reflects a deep commitment to sustainability, innovation, and problem-solving, with ongoing projects including:
- Mixed-Use & Hotel Development (Katoomba, NSW) – A DA-approved project featuring seven residential apartments, a hotel, and a restaurant, where Deboke is delivering civil, stormwater, and structural design solutions.
- NDIS Facility Development – A large-scale DA-approved project comprising 55 standalone dwellings, a community hall, and extensive recreational amenities, where Deboke is managing civil, stormwater, and preliminary structural design.
- Master-Planned Super Lot Subdivision (Lidcombe, NSW) – Civil, stormwater, and flood management for a large-scale residential subdivision, set to accommodate approximately 3,500 residents upon completion.
With a strong reputation for delivering complex infrastructure solutions, Deboke Engineering Consultants continues to push the boundaries of sustainable engineering. Their expertise in stormwater management, structural innovation, and sustainable construction makes them a valuable partner in future-proofing Australia’s transport and infrastructure landscape.
“Sustainability is no longer just an option—it’s a necessity,” says Felfleh. “At Deboke, we are committed to engineering solutions that not only meet today’s standards but also anticipate the challenges of tomorrow.”
