A pilot study at the snow yard to monitor LittaTrap™ performance over 18 months resulted in the installation of 15 units
The City of Brampton, one of Canada's fastest-growing municipalities, is investing in the redevelopment of its Public Works facilities to support future growth, improve operational efficiency, and strengthen its commitment to environmental sustainability.
As part of this initiative, the City upgraded stormwater management at its Sandalwood Works Yard by retrofitting existing catch basins with EnviroPod™ LittaTrap™ and EnviroPod™ Filter technologies.
Following an 18-month field trial, the City expanded the programme across the site, demonstrating confidence in at-source stormwater treatment as a practical solution for protecting downstream waterways while reducing maintenance requirements.
The Sandalwood Works Yard is a critical operational hub responsible for:
During winter, thousands of tonnes of snow collected from across the city are transported to the yard, where they are stored and allowed to melt.
This process concentrates a wide range of stormwater pollutants, including:
The City required a solution that could improve stormwater quality while working within the existing drainage network, without costly reconstruction.
EnviroPod™ Canada, together with Imbrium Systems, partnered with the City of Brampton to trial two complementary catch basin technologies:
Two trial units were retrofitted into existing catch basins and monitored over an 18-month period, allowing the City to assess performance across all seasons, including demanding winter snowmelt conditions.
Because both systems retrofit directly into existing infrastructure, installation required no excavation, construction, or disruption to yard operations.
Following the successful trial, the City expanded the programme across the Sandalwood Works Yard.
A total of 15 catch basins were retrofitted with stormwater treatment technologies, including:
The treatment systems were strategically located according to pollutant risk.
Installed in lower contaminant-generating areas to capture:
Installed in high-loading areas associated with snow storage and snowmelt operations where finer sediments and associated pollutants required enhanced treatment.
Independent testing has demonstrated that the EnviroPod™ Filter removes over 90% of particles larger than 100 microns, helping protect downstream stormwater infrastructure and receiving waters.
The City selected the LittaTrap™ because it provides an effective and economical solution for managing gross pollutants at the source.
Key benefits included:
Using different treatment technologies across the site allowed the City to tailor stormwater treatment to the specific risks presented by each operational area.
The Sandalwood Works Yard upgrade delivered several important outcomes:
The City of Brampton's Sandalwood Works Yard demonstrates how retrofit catch basin treatment can modernise existing stormwater infrastructure without major construction.
Following an extensive 18-month field trial, the City expanded the installation across all 15 catch basins, integrating both LittaTrap™ and EnviroPod™ Filter technologies to manage a wide range of stormwater pollutants.
The project highlights the value of matching treatment solutions to site-specific risks, helping municipalities improve water quality, reduce maintenance requirements, and protect receiving environments while making the most of existing infrastructure.
