Plumbing Work SWMS
Hot and cold water, drainage, gas, and stormwater plumbing including roof penetrations and trench work.
SWMS variants reference your state's WHS legislation. Instant download after payment.
This SWMS covers the full scope of plumbing work on Australian construction sites — hot and cold water service installation, sanitary drainage, stormwater systems, gas fitting, and roof-plumbing penetrations. It is written for licensed plumbers, apprentices operating under direct supervision, and plumbing contractors engaged on new-build residential, commercial, and multi-storey projects. Apprentice supervisors should read this in conjunction with their in-trade competency sign-off schedule. Plumbing work routinely triggers two of the 18 high-risk construction work (HRCW) categories under Schedule 1 of the WHS Regulation 2025 (NSW): Category 11 — confined spaces, and Category 13 — powered mobile plant and powered tools. Where plumbing work also involves trenching deeper than 1.5 metres, Category 14 — trenching — applies. Under Section 299 of the WHS Regulation, a SWMS must be prepared before HRCW commences and must be given to the Principal Contractor on request. This document is CIH-authored against the current regulatory baseline.
Hazards identified
10 hazards covered, sorted by priority.
Oxygen deficiency, H2S exposure, or engulfment can cause unconsciousness and death within minutes; rescue without proper equipment is typically fatal for both worker and rescuer.
Burial under collapsing soil; fatal asphyxiation occurs in under three minutes. Most trench fatalities involve trenches under 2 metres deep.
LPG or natural-gas ignition causing flash fire, deflagration, or explosion; severe burns and blast injuries to the plumber and adjacent trades.
Electrocution during drilling, cutting, or drain-rodding; arc flash burns. Unidentified services are a leading cause of plumber fatalities in Australia.
Third-degree burns to hands, forearms, and face from superheated water at 60C+ or thermal-expansion discharge.
Inhalation of friable asbestos fibres during cutting or removal of legacy AC pipework; Group 1 carcinogen; latent disease (mesothelioma, lung cancer).
Musculoskeletal injury to back and shoulders; repetitive-strain injury over apprenticeship duration.
Lacerations, kickback injuries, eye injury from flying debris.
Bacterial infection (leptospirosis, hepatitis A), parasitic disease, or dermatitis from contact with sewage during repair or connection works.
Fatal or permanent injury from falls greater than 2 metres when working on roof plumbing, gutters, or downpipe installation.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Eliminate confined-space entry wherever possible by specifying assembly at ground level and lowering the completed unit into position.
- 2Where confined-space entry is unavoidable, implement the permit-to-work system per AS 2865-2009 (Confined spaces) — atmospheric testing before and continuously during entry, rescue standby, and two-way communication.
- 3Before any excavation, complete a Before You Dig Australia (BYDA / Dial Before You Dig) lookup and visually locate all underground services; use a cable/pipe locator for final confirmation.
- 4Trenches deeper than 1.5 m must be benched, battered, or shored per AS 2200. A competent person (as defined under WHS Reg r298) signs off the shoring design before entry.
- 5Gas work must be performed only by licensed gas fitters holding the relevant state licence. Pressure-test all gas lines to AS/NZS 5601 before commissioning.
- 6Implement lock-out / tag-out on all electrical circuits in the work area before any wall or ceiling penetration. Use a non-contact voltage tester to verify de-energisation.
- 7Scald control: turn off hot-water systems and allow cooling to ambient before disassembly; fit tempering valves per AS 3498 on potable hot-water outlets.
- 8For any demolition or modification of cement-sheet pipework pre-2004, arrange an asbestos inspection. Licensed Class B removal is required for any non-friable asbestos over 10 m2; friable asbestos requires Class A licence per WHS Reg r485.
- 9Mechanical aids — pipe dollies, hoists, and two-person lifts for items over 25 kg — must be used per the Code of Practice: Hazardous Manual Tasks (SafeWork Australia, 2020).
- 10PPE baseline: Grade II safety eyewear (AS/NZS 1337.1), safety footwear with protective toecap (AS/NZS 2210.3), cut-resistant gloves for sharp pipework, and respiratory protection (P2 minimum) for any dust-generating tasks.
- 11For roof-plumbing work, fall protection per the Code of Practice: Managing the Risk of Falls at Workplaces (SafeWork Australia, 2011): edge protection as the primary control; travel-restraint systems as the secondary; fall-arrest harness per AS/NZS 1891.1 only where higher-order controls are not reasonably practicable.
- 12Biohazard controls for drainage work: disposable nitrile gloves under leather work gloves, disposable coveralls, face shield for splash hazards, and vaccination-currency check (hepatitis A/B and tetanus) for the whole crew.
- 13All plumbers must hold a valid White Card (General Construction Induction, CPCCWHS1001) and their current state plumbing licence; apprentices work under direct supervision per the Plumbing and Drainage Act of the jurisdiction.
- 14Conduct a daily pre-start toolbox talk covering the day's scope, identified hazards, and any changes since the previous day. Record attendance.
Applicable Codes of Practice
Establishes the baseline for HRCW categorisation, SWMS preparation, and principal contractor duties that this SWMS satisfies.
Binding guidance on atmospheric testing, permit-to-work, and rescue arrangements for confined-space plumbing work. From 1 July 2026 this Code is legally binding under Section 26A of the WHS Act.
Referenced for trench-shoring, benching, and spoil-management requirements when installing underground drainage.
Governs fall protection for roof-plumbing activities at or above 2 metres.
Applies when plumbing work involves disturbance of cement-sheet pipework installed before 2004.
Technical standard for installation and testing of water services, sanitary plumbing and drainage, stormwater, and heated-water systems.
High-Risk Construction Work triggered
Drainage, storm, and service plumbing routinely requires entry into pits, inspection chambers, grease arrestors, and ceiling spaces that meet the AS 2865-2009 definition of a confined space.
Rotary hammers, reciprocating saws, powered crimping tools, and concrete corers used throughout the work trigger this category.
Drainage and service installation frequently requires trenches exceeding 1.5 metres in residential and commercial construction.
Roof-plumbing, gutter, and stormwater outlet installation involves working on pitched and flat roofs exceeding 2 metres above the level below.
Because this work triggers multiple HRCW categories, Section 299 of the WHS Regulation 2025 requires the SWMS to be prepared before work commences, kept available on site for inspection, reviewed and updated if the work changes, and provided to the Principal Contractor on request. Failure by a PCBU to prepare or keep a current SWMS for HRCW is an offence under Section 300; maximum penalty for a body corporate is $36,000 per offence, and for an individual $7,200, in addition to any higher-tier prosecution if an incident occurs.

Worked example
A three-person plumbing crew — one licensed plumber, one fourth-year apprentice, one labourer — is subcontracted to install 45 m of 100 mm PVC stormwater drainage behind a new four-townhouse block in Parramatta. The trench runs 1.6 m deep through clay with one utility crossing (Telstra conduit, located by BYDA). Before work commences the plumber completes this SWMS: the trenching triggers HRCW Category 14 and requires shoring per AS 2200; the proximity of the Telstra conduit triggers an exclusion zone; the PVC cutting triggers powered-tool PPE. The SWMS is signed by the PCBU, handed to the Principal Contractor, acknowledged by all three workers via the sign-on register, and posted in the site shed. At lunchtime on day 2 a service-location change emerges; the SWMS is amended, re-acknowledged, and the updated version filed.

Frequently asked questions
Does this SWMS cover licensed gas-fitting work?
Yes, the document includes hazards and controls for gas-fitting work including pressure-testing to AS/NZS 5601. However, the SWMS does not replace the gas-fitting licence itself; licensed gas-fitters must perform gas work and certify it per their state licensing scheme.
Can I use this SWMS in Victoria?
You can use it as a starting point, but Victoria operates under the OHS Act 2004 and OHS Regulations 2017 rather than the model WHS Act. The legislation schedule at the end of the SWMS should be updated with OHS-Act equivalents, and the relevant WorkSafe Victoria Compliance Codes should be cited in place of the SafeWork Australia Codes of Practice.
Does the SWMS include a confined-space entry permit?
The SWMS references the permit-to-work system per AS 2865-2009 but does not include a permit template. Most PCBUs issue permits separately at the time of each entry using their own site-specific permit. If you need a permit template bundled with the SWMS, contact us about a custom document.
How often does this SWMS need to be reviewed?
The WHS Regulation requires review whenever the work or its associated hazards change materially, after an incident, or when a worker raises a concern. As a minimum, we recommend a full review every 12 months, at the start of each project, and whenever the regulatory baseline changes (for example, the 1 December 2026 Workplace Exposure Limit transition).
Can I customise the document for my company logo and details?
Yes — the DOCX includes editable header and title-page fields for your company name, ABN, logo, and site details. All text is editable in Microsoft Word. Replace the generic PCBU and site-address fields before issuing the SWMS to your Principal Contractor.
Is this SWMS compliant with the 1 July 2026 Section 26A changes?
Yes. From 1 July 2026, 34 approved Codes of Practice become legally binding under the amended WHS Act. This SWMS already cites the currently-approved Codes that will be binding, including the Codes of Practice for Construction Work, Confined Spaces, Excavation Work, Managing the Risk of Falls, and Asbestos Management. No amendment is required for the 2026 transition.
