Guidance on use of rainwater tanks

5. Prevention measures and corrective actions

Page last updated: March 2011

Health and aesthetic hazards for rainwater collected in tanks can be minimised by sensible preventive management procedures.

The possible exceptions are the impacts of urban traffic emissions in highly populated centres, and industrial emissions. Some of the preventive measures are associated with design and installation while others are associated with ongoing maintenance. Well designed systems are low maintenance.

Implementation of a relatively low-key management approach will generally prevent problems occurring so corrective action to restore water quality will be needed infrequently, if at all.

Potential sources of hazards, preventive measures and corrective actions are summarised in Table 2 (Sources of potential health hazards and preventive measures) and Table 3 (Sources of aesthetic hazards and preventive measures).
