The state side, in a sentence or two. Plumbing in Bendigo is regulated by Victoria's Building and Plumbing Commission (formerly the Victorian Building Authority), which accredits individual plumbers by class and requires a licensed plumber's compliance certificate for jobs worth more than $750 and for some gas and drainage work regardless of cost. Our Melbourne plumbers page covers those rules and the 2027 gas changes, which apply here too.
Dual pipe estates. Coliban Water lists six developments where new properties must connect to recycled water: Barlow Hills, Canterbury Estate, Evergreen Waters, Evergreen Links and Rubicon Rise Estate at Jackass Flat, and Peppercorn Estate at White Hills. Plumbers there follow its Conditions of Connection for Dual Pipe Areas. Coliban's approved contractor inspects at tapping and meter installation, and its own staff then inspect the meter-to-house pipework, the rough-in and the final commissioning. Each inspection needs at least 48 hours' notice, and the plumber has to be on site for the first and the last.
Rural channel water. Coliban Water's 2024–25 Rural Water Guide counts 1,133 rural licences, supplied through about 500 kilometres of channels and pipelines, and the Victorian Water Accounts describe the open channel system as running from Malmsbury to Bendigo and on to Raywood. Pipeline systems such as Harcourt's give customers water all year. The guide says rural water is untreated and not suitable for human consumption, and that no quality standards apply to it. A plumbing site can describe the tank, pump and filter work you do on these properties without suggesting the water becomes drinkable.
Backflow on commercial sites. Coliban Water publishes a Backflow Prevention Containment Policy (version 2, July 2024) that it shares with several other Victorian water corporations. It requires a testable device at or near the boundary of every property rated medium or high hazard. For a new non-residential development where the hazard or business activity isn't known, the water corporation specifies a high hazard device, and consent to connect is only granted once the backflow documentation is in. The owner then agrees to have the device maintained and tested at intervals of no more than 12 months. Homes with a Class A recycled supply need a dual check valve or dual check meter on both the recycled and drinking water services.
Septic tanks. On unsewered land, the City of Greater Bendigo must consent before a septic system is installed or altered, and a Land Capability Assessment checks whether the block can manage wastewater on site. Before the system is used, the City inspects it and issues a permit. Owners trying to find an old tank can lodge a file retrieval request for the property's records. We're an Adelaide team and work with Bendigo plumbers by phone and email: you send your details and photos, check the draft on your phone, and pay once you're happy with it.
