ABSTRACT
ABSTRACT: Although stormwater infiltration has been practiced successfully for many years, some regulatory agencies are hesitant to adopt such technologies due to concerns over water table mounding, aquifer contamination and efficiency losses due to clogging. The onus, in such cases, is on the research community to perform the work necessary to demonstrate the effectiveness and reliability of the approach. In recent years, the Groundwater Research Group at the University of Toronto has worked with industry partners to develop and refine technologies suitable for the infiltration of stormwater in urban areas. The work has involved comprehensive field, laboratory and computer model studies and the primary focus has been the efficiencies and maintenance needs of two contrasting technological approaches to stormwater infiltration. Research to date indicates that both approaches can be effective for a wide range of hydrogeological conditions and that potential water quality concerns are unlikely to be an issue.
