Cleaning Guidelines

Cleaning Guidelines

Gross pollutants (litter and debris) in urban waterways are unattractive, disturb the physical habitat, degrade the water, attract pests and vermin, can cause marine animal deaths and promote littering and reduce amenity values. (Extract from “From Roads To Rivers-Gross Pollutant Removal From Urban Waterways” Allison, Walker, Chiew, O’Neill, McMahon, May 1998).
These guidelines have been prepared in accordance with the principles of Best Management Practice (BMP) as it relates to stormwater quality and is only applicable for SmartStream Technology Pollutant Trapping Device/Systems.
The guidelines assume that the appropriate pollutant trap has been selected based upon the type of pollutants that the unit is expected to trap, and it is fit for engineering and hydraulic requirements for the chosen location. (ie. flow rates, pipesize, capacity, cover type etc).
MPT’s trap gross pollutants, sediment and hydrocarbons (refer to Glossary), before they enter a waterway, wetland, pond, or other stormwater treatment device, thereby preventing unsightly litter and pollutants entering these water bodies whilst also preserving capacity and pond/wetland shape.
MPT’s capture litter at a single location for easy removal and are appropriate for greenfields sites and retrofitting into existing urban/rural residential and industrial areas, The effectiveness of MPT’s like any pollutant trap, is dependant to a large degree upon the cleaning and maintenance program put into place for each unit. The two primary characteristics that determine long-term effectiveness of a gross pollutant trapping system are the trapping efficiency and the maintenance program.
