Stormwater drain filtration has now become and will continue to be a key to pro-actively playing a part in minimising the impact of pollutants reaching environmental habitats. Water runoff from all exposed surfaces risks pollutants entering our waterways. Outdoor parked vehicles, machinery, roads and driveways are all potential sources. For businesses with stormwater drains on-site, a Drain Warden is a practical, economic investment that requires no effort once installed other than a periodical inspection.
