The Guidelines for Sewerage Systems - Sewerage System Overflows is one of a suite of documents comprising the National Water Quality Management Strategy. These Guidelines provide advice on reclaimed water quality, level of treatment, safeguards and controls and monitoring
Most Australian cities and towns are served by sewerage systems although there are situations where properties are not serviced. In general sewage is conveyed from domestic and commercial users to treatment plants, where it is treated and discharged into receiving environments or re-used. Separated biosolids are either re-used or disposed at landfills.
Historically, the primary environmental management emphasis has been on the appropriate management of discharges from sewage treatment plants. However, sewerage systen1s have a variety of potential envirol1lnental impacts, including sewer odour and gas emissions of a potentially poisonous and explosive nature, noise from pumping stations, and sewage overflows, which must be managed. Management of sewage overflows will be discussed in detail in these guidelines.
