The City’s recreational water monitoring program is a proactive approach to protecting human health. Sites across the City are regularly monitored to determine suitability for recreational activities. This is to protect against issues such as sewage spills, algal blooms and other health related incidents.

All waste water systems must be approved by the City prior to installation and use.
There are two main types of effluent disposal systems, a conventional system and a nutrient retentive system. The location of your property will determine which system is required and it is recommended that you speak to Health Services prior to deciding which system to purchase.
