The water and sanitation department of the city is responsible for ensuring that every street and neighbourhood is clean at all times through waste collection. The department also maintains sewerage systems in the city and ensures that every consumer gets clean water from the main supply lines. Since poor plumbing and contamination in buildings can lead to contamination of water in the main line through backflow, the city requires property owners to hire accredited plumbers to offer plumbing services. Every connection to the main water supply line must also have a backflow device fitted to ensure contaminated water from a building does not contaminate the city’s main water supply pipes.
When it comes to backflow Sydney water consumers need to pay attention to the regulations that govern installation, maintenance and use of these devices. For one, they are required to have the device inspected and tested by an accredited plumber every year.
