Pool & Spa Plumbing Install & Service SWMS
A Safe Work Method Statement for pool & spa plumbing install & service covering all key hazards, controls and regulatory requirements.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Pool and spa plumbing covers the plumbing of swimming pools and spas — the circulation, filtration, heating, water-treatment and balance-tank pipework, and the connection to the water supply with backflow protection. It combines the plumbing with the pool-specific hazards: the pool chemicals used in water treatment, the circulation and filtration systems, the heating, the proximity to water and electrical equipment, and the suction-entrapment hazard of pool circulation. This document is written on the basis that pool and spa plumbing is carried out by a licensed plumber with the chemical, circulation, suction-entrapment, electrical and backflow controls in place.
Pool and spa plumbing is carried out in connection with the relevant parts of AS/NZS 3500, with backflow protection to AS/NZS 3500.1 on the supply connection, the pool water-treatment chemicals managed as hazardous chemicals, and the circulation and suction systems installed so suction-entrapment is prevented. The pool chemicals, the circulation and suction, the heating, and the water-and-electrical proximity are the considerations. This document coordinates the chemical, circulation, suction-entrapment, electrical and backflow controls so the pool and spa plumbing is carried out safely.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Administrative: manage the pool water-treatment chemicals as hazardous chemicals to their safety data sheets, with skin, eye and respiratory protection, handling controls, and prevention of incompatible-chemical reaction and gas release.
- 2Engineering: install the circulation and suction systems so suction-entrapment is prevented — compliant outlets, covers and dual or anti-entrapment arrangements — because pool suction can entrap and drown.
- 3Engineering: provide and confirm backflow protection on the pool and spa connection to the drinking water supply to AS/NZS 3500.1.
- 4Administrative: have pool electrical equipment installed and worked on by a licensed electrician, recognising the electrical hazard around water, and manage the circulation, filtration and pressure systems.
- 5Engineering: manage the pool heating and hot water and the scalding hazard, and the biological hazard of the pool water and balance tank with hygiene controls.
- 6Engineering: use mechanical aids for the pumps, filters and equipment, and confirm the system, suction-entrapment prevention and backflow protection on commissioning.
- 7PPE: chemical-resistant gloves, eye and face protection and protective clothing for the pool chemicals, per the safety data sheets.
- 8Administrative: ensure the work is carried out and certified by an appropriately licensed plumber, drainer or gasfitter under the relevant state or territory plumbing and gasfitting licensing scheme, with the relevant competencies and a compliance certificate issued where required.
- 9Administrative: all workers must hold a valid White Card (General Construction Induction Training, CPCCWHS1001) where the work is construction work, with the plumbing, gasfitting, confined space and any other competencies required for the work.
- 10Administrative: conduct a pre-start toolbox talk covering the day's work, identified hazards, isolations, required PPE and emergency procedures, and record attendance in the consultation section.
- 11Administrative: consult workers and any health and safety representatives on the work and its risks, record the consultation, and keep this document available at the workplace.
- 12PPE: eye protection to AS/NZS 1337.1, hearing protection where required, gloves appropriate to the task, high-visibility clothing, and Class I or Class II safety footwear with protective toecap to AS/NZS 2210.3.
- 13Administrative: review and update this SWMS whenever the work scope changes, after any incident or near miss, when a worker or health and safety representative raises a concern, when new hazards are identified, or at minimum every 12 months.

Worked example
A licensed plumber is engaged to install the plumbing for a swimming pool and spa. The pool water-treatment chemicals are managed as hazardous chemicals to their safety data sheets, with skin, eye and respiratory protection, handling controls, and prevention of incompatible-chemical reaction and gas release. The circulation and suction systems are installed so suction-entrapment is prevented — compliant outlets, covers and anti-entrapment arrangements — because pool suction can entrap and drown. Backflow protection on the pool and spa connection to the drinking water supply is provided and confirmed to AS/NZS 3500.1. The pool electrical equipment is installed and worked on by a licensed electrician, recognising the electrical hazard around water, and the circulation, filtration and pressure systems managed. The pool heating, hot water and scalding hazard, and the biological hazard of the pool water and balance tank, are managed. Mechanical aids are used for the pumps and filters. The system, suction-entrapment prevention and backflow protection are confirmed on commissioning, and the records retained.

Frequently asked questions
What is the suction-entrapment hazard?
Pool circulation systems draw water through suction outlets, and a person can be trapped against an outlet by the suction, which can cause entrapment and drowning. The circulation and suction systems are installed so suction-entrapment is prevented — compliant outlets, covers and dual or anti-entrapment arrangements — because pool suction can entrap and drown.
What chemical hazards apply to pool plumbing?
Pool water-treatment chemicals can cause chemical burns, toxic exposure and hazardous reactions, particularly if incompatible chemicals are mixed and release gas. They are managed as hazardous chemicals to their safety data sheets with appropriate protection and handling controls, and incompatible-chemical reaction and gas release prevented.
How is the drinking water supply protected?
Backflow protection is provided and confirmed on the pool and spa connection to the drinking water supply to AS/NZS 3500.1, because the pool water presents a backflow hazard. The backflow protection prevents contamination of the drinking water supply from the pool and spa.
Who does the pool electrical work?
The pool electrical equipment is installed and worked on by a licensed electrician, recognising the electrical hazard around water, because it is electrical work in a high-risk wet environment. The plumber installs the pool plumbing, and the electrical work is carried out by the appropriate licensed electrician.
Who carries out pool and spa plumbing?
Pool and spa plumbing is licensed plumbing work carried out by a licensed plumber in connection with the relevant parts of AS/NZS 3500 and the pool circulation requirements, with the chemical, suction-entrapment, electrical and backflow controls. The system and its safety arrangements are confirmed on commissioning.
