Abstract / Summary:
There is increasing public concern about the large amount of gross pollutants, such as litter and debris, observed in urban waterways and receiving waters. These pollutants are unattractive, disturb the physical habitat, degrade the waters, are linked to marine animal deaths and reduce amenity values.
A number of approaches are used to reduce the problem: public awareness and education programs, penalties for littering, the provision of collection bins and extensive street cleaning. Despite these efforts it is clear that significant amounts of material enter the urban drainage system. Traps can be installed to collect gross pollutants and can be located at street channel entry pits, within main drains and in slow moving receiving waters. However, it is rarely feasible to provide sufficient trapping to collect all the pollutants in the urban drainage system.
This report describes a decision-support-system (DSS) that can be used to assist Authorities select an appropriate strategy for trapping gross pollutants from a particular urban area. The DSS takes into account the urban drainage layout, trapping locations, the predominant land-use type and funding limitations in assessing the benefits and costs of a proposed strategy. The DSS is established using essentially results from a CRC gross pollutant field monitoring study, as well as a review of litter trapping devices commonly used in Australia.
