The Victorian rules, briefly. Geelong plumbers deal with the Building and Plumbing Commission, which replaced the Victorian Building Authority on 1 July 2025. It registers and licenses individual plumbers class by class, and only a licensed plumber can issue a compliance certificate, which is needed when the total value of the work exceeds $750 and for some gas and drainage work whatever it costs. Our Melbourne plumbers page sets those rules out in full, along with the 2027 changes to gas hot water and new home connections, which apply in Geelong exactly as they do in the city.
One water corporation, several councils. Barwon Water runs water and sewerage from Little River and Meredith in the north, across the Bellarine Peninsula and down the coast to Apollo Bay. The councils change along the way: the City of Greater Geelong, the Borough of Queenscliffe, Surf Coast Shire, Golden Plains Shire to the north-west and Colac Otway Shire around Colac and Apollo Bay. People search by suburb or town rather than by council, so that's how your areas are listed.
Purple pipe in the southern estates. Barwon Water supplies Class A recycled water through a dedicated purple-pipe network to homes and businesses in Armstrong Creek and parts of Torquay, Mount Duneed and Charlemont. Each property there has two pipelines, two meters and two sets of taps, with the recycled taps coloured purple. The recycled side is approved for toilet flushing, garden watering and washing cars and paths, but not for drinking, bathing, kitchens, pools or spas. Barwon Water says recycled water plumbing must be inspected by its authorised representative at three key stages, and again if changes are needed after people move in. That's specialised work, and worth naming on your site if you do it.
Backflow and trade waste. Barwon Water asks property owners to have an accredited backflow prevention plumber assess the property's hazard rating. Where it's rated medium to high risk, the owner has three months from the assessment to install backflow prevention devices, must register the property and the devices with Barwon Water, and agrees to have them tested and maintained each year with the results reported to Barwon Water. Owners are told to organise suitably qualified plumbers for all of it. On the sewer side, Barwon Water's trade waste policy says occupiers of commercial and industrial premises must enter a Trade Waste Agreement or obtain a Trade Waste Permit before discharging trade waste to its sewers. Both bring repeat work from the same customers, and both are easy to miss on a plumber's site that only lists domestic services.
Where the sewer stops. On unsewered land, the City of Greater Geelong issues a Permit to Alter/Install an onsite wastewater management system, which council says may take four to six weeks, and an Approval to Use once a final inspection shows the system complies, usually within two weeks of that inspection. Using a system before then can bring an infringement notice. Council suggests checking with Barwon Water first whether a property is sewered, and pump-to-sewer is an option to raise with Barwon Water too.
