TRIED AND TESTED

DKERB Gross Pollution Trap was put through its paces by the University of New South Wales, coming out with top marks.

BR Durham & Sons are known for itsquality range of precast concrete stormwater and utility pits, kerb inlets, covers and grates. After extensive research and development, Durham has added to its complete kerb inlet and Gross Pollution Trap range in launching a new application — the DKERB Gross Pollution Trap (GPT).

Durham, in association with the Water Research Laboratory (WRL) at the University of New South Wales (UNSW), had its new Gross Pollution Trap (GPT) independently tested to rigorously assess the technology under mimicked real-life circumstances.

The university’s WRL thoroughly researched the gross pollution spectrum until they classified a suite of pollutants that met the criteria for anthropogenic pollution, natural litter and suspended sediment for Australian conditions. Inspired by Robert Allison’s CRC for Catchment Hydrology 1998 report and Stormwater Australia’s Stormwater Quality Improvement Device Evaluation Protocol (SQIDEP), UNSW’s WRL designed and constructed a test bench and hand-picked real-life gross pollution from Australian streets to test Durham’s Gross Pollutant Traps under what would be real-life duress. This included plastic wrappers, straws, face masks, water bottles, grass clippings, leaves, a synthesised dense slurry of graded sediment etc. This scientific rigour produced amazing findings, consistent with the Durham reputation for practicality, reliability and excellence in product range and results.

Durham’s DSTORM and DKERB Gross Pollutant Traps use innovative design and technology to protect the environment. With the ability to be installed into new developments or retrofitted onto existing drainage, they utilise smooth bar technology (SBT) to allow their screens to self-clear between storm events and restore treatable flows. They have been especially designed for ease of construction and ongoing maintenance, and their impressive independent test results prove they will deliver a superior environmental outcome.

KEY FEATURES

•             Design combines the kerb inlet with the gross pollution trap.

•             By combining both key pieces of infrastructure, it proves to be cost-effective and environmentally beneficial,
               all while minimising its carbon footprint.

•             Its modular design provides flexibility in construction and configuration.

•             It is specifically engineered to ensure ongoing maintenance is cost-effective
               and simple.

•             It is made with the highest-quality concrete and stainless steel.

•             Implements Smooth Bar Technology (SBT) to ensure it self-clears between events.

•             Designed to ensure it has covers on opposite sides of the device’s screen, so a combination unit can easily access 100 percent of the                     device for a thorough clean.

•             No internal moving parts means the elimination of WHS hazards.

•             Monitoring and maintenance remain safe, efficient and cost-effective long-term.

•             Has been independently proven to remove 100 percent anthropogenic gross pollution, and 50 percent suspended sediments.
