Plumbing and Drainage

View from Warragamba Lookout

Due to changes that commenced on 1 July 2012, all plumbing and drainage work in NSW is regulated under the Plumbing and Drainage Act 2012.  As a result, NSW Fair Trading is the sole regulator for plumbing and drainage works across the State.  Outside metropolitan areas, Fair Trading have delegated functions to local Councils to inspect plumbing and drainage works where they are not connected to services or assets of Sydney Water or Hunter Water Corporations.

What type of work requires an inspection? 

You must book inspections for all sanitary drainage work, onsite sewage management facilities and recycled water plumbing within Wollondilly Shire; that is not connected to a Sydney Water service or asset.

Required inspections prior to backfilling or covering include:

  • New internal sanitary drainage;
  • New external sanitary drainage;
  • Alterations and additions to existing sanitary drainage;
  • New onsite sewage management facilities or alteration to existing systems (i.e.septic and wastewater treatment systems);
  • Any work for alternative water supply systems, such as recycled water plumbing, greywater/blackwater treatment systems, pumpout, etc.

Before commencing work

By law, only authorised persons can carry out plumbing and drainage work in NSW.  Plumbers and drainers must submit a Notice of Work (NoW) to Council before starting any plumbing or drainage work, except in specific circumstances.  A Certificate of Compliance (CoC) and a Sewer Service Diagram (SSD) are required on completion of work.  Copies can be downloaded from  NSW Fair Trading,

Fees are applicable for inspections in accordance with Council’s adopted Fees and Charges and in the case of onsite sewage systems, works requiring approval under Section 68 of the Local Government Act, 1993 will also incur a fee.  These fees and approvals are required prior to the commencement of any plumbing and drainage work.

Change of licensee details

You must notify Wollondilly Shire Council if the onsite licensee changes.  Where a licensee takes over work, both licensees must make sure their NoW and CoC accurately describe the work they have done or are about to do.

The original licensee will need to arrange for a final audit inspection to complete their work. They will also need to supply an updated NoW, SSD and CoC that accurately describes the work completed to date.

The new licensee must ensure the required fee is paid and a NoW is submitted that accurately describes the work they will be responsible for. 

Inspections

Prior to booking an inspection, a NoW and inspection fees must be submitted to Council unless previously arranged.  You will need to provide a contact name and number, details of the type of inspection(s) requested and any specific site access requirements (gate keys or codes, unrestrained dogs, etc).

Contact Council on 4677 1100 between 8am and 4.30pm weekdays to book an inspection.  Inspections are carried out during normal business hours, Monday to Friday, and must be booked a minimum of one business day before the required inspection.  Unfortunately due to the size of Wollondilly Shire, inspection times cannot be booked however we will do our best to accommodate preferred timeframes where possible.

There is no need to be present during an inspection, however you may wish to be present or in some circumstances, Council’s officer may request to meet with you for a specific inspection (such as recycled water flow tests).

Should you need to cancel an inspection, you must call Council before the inspection is carried out, usually before 10am on the day of the required inspection.  If an inspection is not cancelled and an officer attends the site, you may be invoiced for a reinspection.

After an inspection is completed, Council’s officer will contact you by phone or in writing to advise the result of the inspection.  If the result is defected, works must not continue until the defects have been rectified.  If a reinspection is required, this must be arranged prior to development continuing.  Should you not receive a phone result, you will need to call Council to ascertain if the development can progress.

Council takes missed inspections extremely seriously, as it prevents us from carrying out our regulatory duties and ensuring works are completed to an appropriate standard.  Regularising unauthorised works and missed inspections is not an easy process and may result in delays, exposing covered works, reporting the licensee to Fair Trading, the issue of penalties or even legal action.
