JERRABOMBERRA CATCHMENT POLLUTION CONTROLS

There are a number of sites in the Jerrabomberra Creek catchment area which are recognised by the Pollution Control Authority as potential sources of pollution and for which licences controlling their operation have been issued. The licence conditions are set to reduce the level of pollution to the lowest practicable level.

Within the catchment area there are sources of pollution which are typical of semi urban catchment and include:

Construction works and soil disturbance, Urban litter, Localised discharges, Sewage treatment, Extractive industries, Landfill, Commercial point sources, and Animal park and zoo facilities.

The controls on these sources are as follows:

Construction Works

- The water Pollution Act requires that construction sites be licenced and have pollution control measures installed and operated to the satisfaction of the Pollution Control Authority. Recently, a breach of a licence resulted in prosecution. Except during the recent major floods in Jerrabomberra Creek, (one with a return frequency of approximately 1 in 50 years and another with a return frequency of 1 in 10 years) the waters were barely affected by these works.
