Plumbing and Drainage Inspections
All plumbing and drainage work carried out in the Hawkesbury City Council is required to comply with the Plumbing Code of Australia and Australian Standard AS/NZS 3500.
Plumbers and drainers working the Hawkesbury City Council Local Government Area (not including the Sydney Water sewered areas) must contact Hawkesbury City Council to book inspections for approved works, pay fees, submit documentation and for enquiries.
If you are unsure whether the land is serviced by Council’s sewer, Sydney Water or is unserviced please contact Council’s Customer Service Centre on (02) 4560 4444.
Note: The Plumbing and Drainage Act 2011 and Regulation provides that NSW Fair Trading is the single plumbing and drainage regulator for all on-site plumbing and drainage work in NSW. Fair Trading has delegated certain functions under this Act to Hawkesbury City Council for plumbing and drainage works within the Council area.
