People and domestic animals naturally carry pathogens that can be transferred into streams and reservoirs when they have contact with the water. The pathogens can be difficult to remove, putting our drinking water at risk and potentially making people sick. There are also restrictions on other activities such as off-road driving, camping, lighting fires and littering. Failure to comply with these rules may result in an infringement or prosecution.

All Perth’s metropolitan and regional dams are proclaimed Public Drinking Water Source Areas and are protected under the Metropolitan Water Supply Sewerage and Drainage Act 1909, the Country Areas Water Supply Act 1947 and the Water Services Act 2012. Access is not permitted on the reservoirs or in the streams flowing into it. Failure to comply may result in prosecution.
