Water Cart & Dust Suppression SWMS
Water cart and dust suppression truck operations on construction and civil sites — pre-start checks, safe filling at standpipe, road dust suppression, compaction support, and wash-down.

Water cart operation covers the operation of a water cart — running a water cart truck to apply water for dust suppression and compaction on civil and road construction sites. The defining hazards are the water cart as powered mobile plant, the interaction with workers and other plant, any road traffic, and the tank and pump. This document is written on the basis that water cart operation is carried out by a competent operator with the plant, pedestrian-separation, traffic and tank controls in place.
Water cart operation is carried out as construction work in connection with the plant requirements, with the water cart operated safely, the workers and other plant separated, any road traffic managed, and the tank and pump managed. Because the work is in an area of powered mobile plant movement and may be on or adjacent to a road, it is high risk construction work. The plant, the pedestrian separation, the traffic, and the tank are the considerations. This document coordinates the plant, pedestrian-separation, traffic and tank controls so the water cart operation is carried out safely.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Engineering: use the road and civil plant — pavers, rollers, profilers, graders, rigs and trucks — safely to the plant requirements and the manufacturer's instructions, with guarding, pre-operational checks, competent operators and the plant maintained.
- 2Engineering: separate pedestrians and powered mobile plant with designated routes, exclusion zones, spotters and a traffic management plan, because pedestrian and plant interaction is a leading cause of serious injury on civil sites.
- 3Engineering: manage the reversing and manoeuvring of the water cart with a procedure, cameras and a spotter.
- 4Engineering: where on or adjacent to a road, manage the road traffic with a traffic management plan and traffic control.
- 5Engineering: manage the tank, pump and spray system safely, and the water cart stability when loaded and on slopes.
- 6Administrative: manage the slippery surfaces from the water, and other plant and trucks on site.
- 7Administrative: manage the filling and water supply safely.
- 8Administrative: because the work is carried out in an area in which there is movement of powered mobile plant, prepare a SWMS for the high risk construction work before it commences, with the pedestrian and plant separation implemented.
- 9Administrative: all workers must hold a valid White Card (General Construction Induction Training, CPCCWHS1001), with the plant tickets, traffic control accreditation, confined space, and other competencies required for the work.
- 10Administrative: conduct a pre-start toolbox talk covering the day's work, identified hazards, the traffic and plant movements, 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: high-visibility clothing to AS/NZS 4602.1, eye protection, hearing protection where required, gloves appropriate to the task, 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.
- 14Administrative: confirm the work is completed safely, the excavation, plant and area are left in a safe condition, and the site is secured.
Applicable Codes of Practice
Controls for the road and civil plant, rigs, rollers and pavers used in the work, including guarding and safe operation.
The general construction work duties for the civil road work, including the SWMS and principal contractor duties.
The separation of workers and plant from live road traffic, traffic guidance schemes and traffic control.
The risk management process and hierarchy of controls applied to the hazards of the work.
The control of the manual handling and awkward postures of the work, including pipes, barriers and materials.
High-Risk Construction Work triggered
The work is carried out in an area in which there is movement of powered mobile plant, which is high risk construction work requiring a SWMS before the work commences.
Where the water cart operates on or adjacent to a road in use by traffic other than pedestrians, it is high risk construction work requiring a SWMS and a traffic management plan before the work commences.
This is civil construction work that, in the circumstances described, is high risk construction work — involving in an area at a workplace in which there is movement of powered mobile plant; on, in or adjacent to a road, railway, shipping lane or other traffic corridor in use by traffic other than pedestrians — so a SWMS must be prepared before the work commences, kept readily accessible, reviewed as necessary, and given to the principal contractor if one is appointed. The work is carried out in connection with the relevant construction, excavation, traffic, plant and other requirements, with the controls for the specific hazards applied. A failure in this work can cause a fatal trench collapse, traffic, plant, fall, gas or other serious injury, and breaches of the relevant legislation and the primary duty of care under the model WHS Act are actively enforced, with offence categories running from failure-to-comply through to reckless conduct, and the most serious breaches carrying imprisonment for individuals. Body-corporate maxima are substantial and indexed; the current maximum follows the prevailing schedule of the responsible regulator.

Worked example
A competent operator is engaged to run a water cart for dust suppression and compaction. The water cart is operated safely to the plant requirements, with pre-operational checks. Workers and other plant are separated from the water cart with designated routes, exclusion zones and spotters. The reversing and manoeuvring are managed with a procedure, cameras and a spotter. Where on or adjacent to a road, the road traffic is managed with a traffic management plan and traffic control. The tank, pump and spray system, and the water cart stability when loaded and on slopes, are managed. The slippery surfaces from the water, and other plant and trucks, are managed. The filling and water supply are managed safely. Because the work is in an area of powered mobile plant movement, a SWMS is prepared for the high risk construction work. The water cart operation is carried out, and the records retained.

Frequently asked questions
What is the main hazard operating a water cart?
The hazards are the water cart as powered mobile plant, the interaction with workers and other plant, the reversing and manoeuvring, any road traffic, and the water cart stability when loaded. These are managed with the plant, pedestrian-separation, traffic and tank controls.
Is water cart operation high risk construction work?
Yes — it is carried out in an area of powered mobile plant movement, and may be on or adjacent to a road, both of which are high risk construction work requiring a SWMS before the work commences. Water cart operation triggers the powered-mobile-plant and, where on a road, the traffic-corridor high risk construction work categories.
Why is a water cart used?
A water cart applies water for dust suppression and for compaction on civil and road construction sites, controlling dust and assisting compaction of the earthworks and pavement. The water cart is operated with the plant, pedestrian-separation and traffic controls.
How is the pedestrian-plant interaction managed?
Workers and other plant are separated from the water cart with designated routes, exclusion zones and spotters, and the reversing managed with cameras and a spotter, because the interaction of workers and the water cart is a leading cause of serious injury. Separating workers and plant is a defining control in water cart operation.
Who operates a water cart?
Water cart operation is carried out by a competent operator in connection with the plant requirements, with the plant, pedestrian-separation, traffic and tank controls, and a SWMS for the high risk construction work. The water cart is operated with the plant, pedestrian separation and traffic managed.
