Inspections of drainage plumbing work

Drainage plumbing inspections are carried out by plumbing inspectors while the work is under construction. Most drainage plumbing inspections will arise from notifications (r.70 notice) made by, or on behalf of, the licensed plumbing contractor responsible for the work. A drainage plumbing inspection can also arise at random from a notice of intention or certificate of compliance.

In accordance with regulation 70(1) of the Plumbers Licensing and Plumbing Standards Regulations 2000, licensed plumbing contractors (LPCs) are required to notify the Plumbers Licensing Board (PLB) of when the drainage plumbing is ready to be inspected. The LPC or any representative may submit the r.70 notice.

When should an r.70 notice be given?

All drainage plumbing work that is considered to be major work – such as the installation, alteration or extension of drainage plumbing, and sewer cut and seals – requires notification to be submitted. The r.70 notice must be given prior to 4.30pm on the Wednesday of the week following completion of relevant drainage plumbing work.

How to notify the Board of drainage plumbing work ready for inspection

eNotice submissions

Complete an r.70 notice within the required time of drainage plumbing work completed by choosing ‘Notify Drainage Work Completed’ from the main menu.

Paper certification only

Fill out a ‘Notification of drainage plumbing ready for inspection’’ form (link to form below).

As determined by the PLB, the notice is to be given either:

(a) by telephone on 08 6251 1377; 
(b)  in writing by SMS to 0417 209 818; or
(c) in writing by email to  plumbinginspections@dmirs.wa.gov.au 

The r.70 notice given may be in relation to drainage plumbing work referred to on multiple notices of intention and must include:

• the notice of intention numbers;
• the property addresses;
• the dates the work was carried out;
• a description of the work; and
• the licence number of the responsible plumbing contractor.

The Board would like to remind LPCs that it is their responsibility to test drainage plumbing work in accordance with Section 15 of AS/NZS 3500.2 prior to the placement of trench fill (backfill).

It is the LPC's responsibility to ensure that the drainage plumbing notice is submitted by the required time.
