Lagoon Liner Guidelines

The Environmental Standards Applying to Liner Construction March 2006 (“the Standards”) are intended for use by those proposing to construct wastewater or sewage lagoons and should assist proponents in meeting obligations under the Environmental Management and Pollution Control Act 1994 (EMPCA).

The Standards help to ensure that lagoon liners which are designed and installed in wastewater or sewage lagoons meet minimum environmental protection standards. Correctly designed and installed lagoon liners should minimise the potential for site contamination, specifically groundwater contamination, and safeguard protected environmental values of groundwater.

The standard can be related to law by Section 23A of the Environmental Management and Pollution Control Act 1994 (EMPCA). EMPCA imposes a general environmental duty on all persons who undertake an activity which may cause or be likely to cause environmental harm including environmental nuisance, by requiring them to take all reasonable or practicable steps – such as those contained in these Standards - to prevent or minimise environmental harm.

Similarly, clause 24 of the State Policy on Water Quality Management 1997, requires the person who is responsible for an activity which has the potential to indirectly cause the contamination of groundwater to ensure that appropriate safeguards are taken to minimise the risk and the extent of such contamination.
