Water feature and pond installation combines small-scale civil excavation, low-voltage and 230V electrical work, and the creation of a permanent body of water on a residential or commercial landscape site. The works covered by this SWMS include excavation to design depth, sub-grade preparation, geotextile and EPDM/PVC liner installation, pump and filter wiring through an RCD-protected circuit, edge concealment with stone or timber, and aquatic planting. Because the scope includes excavation exceeding shallow depths in some designs, energised electrical installation work in damp environments, and the creation of a drowning hazard accessible to workers and the public, the activity is classified as High Risk Construction Work under section 291 of the WHS Regulation 2025. A documented, consulted and signed SWMS is mandatory before work commences, must be kept on site for the duration of the works, and must be reviewed if the method or risk profile changes.
Hazards identified
7 hazards covered, sorted by priority.
Crush asphyxiation, traumatic chest injury or fatality when unsupported batter fails on workers in the basin
Cardiac arrest, ventricular fibrillation or fatal electrocution from current passing through wet skin to ground
Asphyxiation by submersion, particularly where a worker is incapacitated by shock, slip or solo work
Electrocution, gas ignition or flooding from contact with live cables, gas lines or pressurised water mains
Acute lumbar disc injury, crush injuries to hands and feet, and chronic musculoskeletal damage to back and shoulders
Fractures, head injury or fall into water leading to secondary drowning or hypothermia
Legionnaires disease, leptospirosis or gastrointestinal illness from aerosolised or ingested contaminated water
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where design allows, specify above-ground or raised-wall water features so excavation deeper than 1.5 m and the associated collapse risk is eliminated entirely.
- 2Elimination — Keep the pond empty and de-energised during all installation stages except final commissioning, eliminating both drowning and live-electrical exposure during construction.
- 3Substitution — Substitute heavy natural stone edging with engineered lightweight cast units under 20 kg per piece to reduce manual handling and crush exposure.
- 4Substitution — Use extra-low-voltage (12V/24V) submersible pumps and lighting via an isolating transformer instead of 230V submerged equipment wherever the design permits.
- 5Engineering — Batter excavation walls to the soil-appropriate angle per AS 2870, or install timber/steel shoring for any excavation exceeding 1.5 m depth before entry.
- 6Engineering — Install a Type I RCD (30 mA) on all circuits supplying the water feature, with double-pole isolation switch located outside the splash zone and lockable for isolation.
- 7Administrative — Conduct Dial Before You Dig search, hand-expose services in the first 500 mm, and brief the SWMS at pre-start with signed acknowledgement from every worker entering the excavation.
- 8Administrative — Prohibit solo work during filling, commissioning and any task within 2 m of standing water; implement a buddy system and exclusion fencing for public and untrained personnel.
- 9PPE — Provide and enforce use of cut-resistant gloves, steel-capped waterproof boots, safety glasses, and high-visibility long-sleeve clothing rated for wet-weather work.
- 10PPE — Supply Class 0 electrical insulating gloves to the licensed electrician for any live testing, and P2 respiratory protection plus nitrile gloves when handling pond water or planting media.
Applicable Codes of Practice
Establishes the duty to assess ground conditions, control collapse, and prevent falls into excavations more than 1.5 m deep for the pond basin.
Defines wet-zone classifications, RCD protection requirements and minimum IP ratings for fixed wiring serving submerged pumps, lights and filters.
Sets out isolation, lock-out tag-out and licensed-electrician requirements for energising any pump or lighting circuit in proximity to water.
Governs batter angles, edge protection and fall prevention around open excavations and partially filled ponds during construction and testing.
High-Risk Construction Work triggered
Pond basins for medium and large water features are routinely excavated between 1.2 m and 2.0 m deep to accommodate liner, pump sump and aquatic plant shelves.
Installation includes hardwiring of 230V submersible pumps, transformers and feature lighting on RCD-protected circuits located within and around standing water.
Mini excavators, dingo loaders and wheelbarrows transport spoil and stone around the work zone, creating crushing and strike risk for ground workers.
The PCBU must prepare, consult workers on, and retain the SWMS for the duration of the work plus two years after a notifiable incident; penalties are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
On a mid-size residential project installing a 1.8 m deep koi pond with a 230V external pump and submerged LED lighting, the landscape supervisor pulls out this SWMS at the Tuesday morning pre-start under the carport. Three workers and a visiting licensed electrician sign on. Walking through the hazards register, the supervisor identifies that today's task — excavating the final 400 mm of the pond shell in sandy clay — triggers the excavation collapse and unknown-service hazards. He confirms the Dial Before You Dig plans are on site, marks the gas line lateral with spray paint, and directs the operator to batter the south wall at 45° rather than vertical as the soil is drier than expected. The electrician is briefed that no cable will be energised until the basin is empty and the RCD-protected isolator outside the splash zone is installed and tested. Mid-morning, an unexpected groundwater seep appears at the base. The supervisor stops work, reviews the SWMS collapse-control section with the crew, and adds a temporary sump pump and an additional 300 mm of batter before re-entry. The amended control is noted in the SWMS revision log, re-signed by all workers present, and the document is returned to the site box ready for the next shift's pre-start brief.

Frequently asked questions
Do I need a SWMS to install a pond or water feature?
For most designs, yes. Filling and commissioning creates a body of water with a genuine drowning risk, which is high risk construction work under WHS Regulation section 291(q). Hardwiring 230 V pumps, transformers and feature lighting engages section 291(k), basins excavated between 1.2 m and 2.0 m engage section 291(g) once past 1.5 m, and mini excavators or dingo loaders shifting spoil and stone engage section 291(o). Section 299 requires the SWMS to be prepared and consulted on before work starts, kept on site for the duration, and reviewed if the method or risk profile changes.
Does this SWMS cover the electrical work, or do I still need a licensed electrician?
You still need a licensed electrician — the SWMS documents the method and controls, not the licence. The documented arrangement is extra-low-voltage 12 V or 24 V pumps and lighting through an isolating transformer wherever the design permits, a Type I 30 mA RCD on every circuit serving the feature, and a lockable double-pole isolator sited outside the splash zone. Wet-zone classification, IP ratings and fixed wiring follow AS/NZS 3000 Section 6, Special Locations. Nothing is energised while the basin holds water, and Class 0 insulating gloves are issued to the electrician for any live testing.
How is the drowning risk managed once the pond starts holding water?
By keeping the basin empty and de-energised through every construction stage except final commissioning, so the drowning and live-electrical exposures never overlap with build work. From first fill onward, solo work is prohibited during filling, commissioning and any task within two metres of standing water, a buddy system applies, and exclusion fencing keeps the public and untrained personnel out. Slip controls cover wet liner, algae-coated stone and muddy excavation edges, because a fall at the water's edge is what turns a slip into a submersion event.
What does it require before anyone gets into the excavation?
A Dial Before You Dig search, hand exposure of services through the first 500 mm, batter angles matched to the actual soil rather than the plan, and timber or steel shoring on any excavation deeper than 1.5 m before entry. Every worker entering the basin signs acknowledgement of the brief. The controls are written to be changed in the field: in the worked example a groundwater seep appears at the base, work stops, a temporary sump pump and an extra 300 mm of batter are added, and the amended control is entered in the revision log and re-signed before re-entry.
What do I get, and does it work for commercial and public installations?
You get an editable Word document, bought once, with the hazard register and risk ratings, hierarchy-of-control mapping, a state-specific legislation schedule for NSW, VIC, QLD, SA, WA, TAS, NT and the ACT, a worker sign-on register, pre-start checklist and incident escalation flow. It suits residential koi ponds, resort and aged-care garden features, pool builders extending into ornamental ponds, and council park installations. Edit it to your design depth, soil type, pump voltage and public exclusion arrangements before use, and re-brief and re-sign it whenever the method changes.
