Plumbing & drainage
Plumbing and drainage works
Plumbing and drainage work relates to sewer drains and water pipes associated with a building.
All plumbing and drainage work must be performed by a licenced plumber. You can search the NSW Fair Trading website for more information about whether a plumber has the required licences to undertake plumbing work.
The sanitary drains provide the means for wastewater (sewage) to be conveyed from the building into the sewer system or on-site sewage management system.
The water pipes convey drinking or non-drinking water to the building from a water supply such as the water mains, rainwater tank or approved alternative water supply.
Stormwater work must be conducted by a licenced plumber.
Stormwater work associated with new building work requires inspection by a Principal Certifying Authority as part of the construction approval process.
Stormwater work is regulated under the Home Building Act 1989.
Cessnock City Council is the plumbing and drainage regulator for areas of the Cessnock Local Government Area that are not serviced by the Hunter Water Corporation (non-sewered) or serviced by an alternative water supply (such as Huntlee).
All areas serviced by Hunter Water remain the responsibility of NSW Fair Trading.
Council may inspect non sewered residential development such as:
- sanitary drainage (including sanitary plumbing) up to point of connection to the main or pressure sewer unit
- water plumbing from the point of connection to the main or alternative water supply source to the fixtures within the building
