Abstract: Water quality problems from impermeable urban surface runoff are presenting increasingly significant effects at both the short-term, acute, and longer term, chronic, timescale. The paper identifies the anachronism in, and the diversity of, historical organisation responsibilities for urban runoff as being a principal mitigating factor in limiting satisfactory, cost-effective, catchment control. It is recommended that effective source control procedures for stormwater runoff control must form the basis for best practical options for achieving integrated pollution control in urban catchments.
