Smart Infrastructure for Sensitive Environments
HumeFilter helps improve stormwater quality in Victoria’s waterways
Wetlands are some of Victoria’s most valuable natural assets — filtering runoff, supporting biodiversity, and acting as natural buffers in times of flood. Protecting them starts upstream, with smart infrastructure that improves water quality before it reaches sensitive environments.
Installed by a Victorian local council, the HumeFilter universal pollutant trap (UPT3000) shows how innovative precast stormwater systems can meet performance goals on tight urban sites. Designed for installation beneath roads and in limited-space areas, the UPT3000’s triple-stage filtration helps reduce sediment, nutrients and other pollutants in stormwater runoff.
The units, from Holcim’s precast concrete division Humes, use 50 MPa concrete with a 25% flyash blend, reducing embodied carbon and enabling a fast, low-impact installation. With only a 50mm fall between inlet and outlet, Humes engineered a bespoke internal insert — demonstrating the flexibility of the system for complex layouts.
As part of Humes’ Nature Series, the UPT3000 contributes to more resilient, sustainable water infrastructure — supporting better outcomes for both people and the environment.
