Licensing is statewide. A Bunbury plumber holds the same Plumbers Licensing Board licence as one in Perth, and the rule that your PL number appears in your advertising is the same too. Our Perth plumbers page explains those regulations, along with the notice and certificate of compliance for a hot water replacement. The part that's different in Bunbury is who supplies the water.
Aqwest's patch. Aqwest, the trading name of the Bunbury Water Corporation, holds a licence for the Greater Bunbury region from Myalup and Harvey down to Capel, but at present supplies drinking water only to Bunbury, Picton and parts of Dalyellup, and tells Dalyellup residents to check their bill if they're not sure. Wastewater is another utility again: the Bunbury Wastewater Treatment Plant belongs to the Water Corporation, and Aqwest's planned water recovery scheme would treat recycled water from it to irrigate the Hay Park sporting precinct. Aqwest points customers outside its area to the Water Corporation's or Busselton Water's own programs, so a site covering Australind, Eaton and Bunbury should say which supplier's paperwork you can help with.
Where Aqwest's job ends. Aqwest maintains the mains, the stop tap and the meter. From the valve just before the meter into the building, the pipes are the owner's, and any work on them has to be done by a licensed plumber. Meters are generally about half a metre in from the front boundary, and owners must keep a clear space around them of at least 300 mm horizontally and 1,200 mm vertically. A relocation starts with Aqwest's relocation or disconnection form and a plan showing the existing and proposed meter positions; Aqwest quotes, the owner pays in full and pegs the new location, and Aqwest then moves the meter within 10 working days or on an agreed date. Testable backflow devices in its area are tested once every 12 months by an accredited backflow plumber, and the results go to Aqwest within 5 working days of the test.
Water quality and hot water units. Aqwest describes its water as about 100 mg/L of calcium carbonate, which it calls moderately soft to slightly hard, and says hardness affects how long hot water systems last and the warranty on some dishwashers. Its quick check for pressure is filling a 10-litre bucket from the tap nearest the meter: 30 seconds or more suggests the pressure may be low and should be reported to Aqwest, while problems inside the home, such as corroded pipes or an old galvanised service, are a job for a licensed private plumber. Both are useful lines for a plumber explaining hot water servicing or a re-pipe.
Suburbs, and working with us. The City of Bunbury is compact, with localities such as East Bunbury, Glen Iris, Usher, Withers, College Grove and Pelican Point. At the 2021 census it had 32,987 residents, while the Shires of Harvey, Capel and Dardanup, which share the Greater Bunbury Region Scheme with it, had about 61,000 between them. Customers search by those names, so list the ones you'll go to. We're an Adelaide team working with South West businesses by phone and email, and we haven't yet built for a WA client, so the examples below are from Queensland and South Australia. Bunbury keeps Perth time, 1.5 hours behind Adelaide, or 2.5 hours during South Australian daylight saving.
