Water industry operatives work in treatment plants and pumping stations throughout Western Australia, though the majority of employment opportunities are in the Perth metropolitan and South West regions of the state. They may work both indoors and outdoors in most weather conditions. Water treatment plants can be smelly, however most plants have processes in place to minimise unpleasant odours. These workers frequently work with dangerous chemicals and must follow strict occupation health and safety procedures to reduce risks. Most water industry operatives work standard business hours, though some plants may require weekend work. Water industry operatives may also be required to be on call in case problems arise at the plant after hours.

Water industry operatives operate pumps and valves used to transport water and effluent and must be able to read the gauges to monitor these operations. They also use laboratory equipment to collect and test water samples for purity, colour, pH (acidity) and general quality. Chemicals, such as fluoride, are added to water in very specific quantities, requiring careful handling and measuring. Water industry operatives may also be required to wear safety equipment, such as gloves, masks, goggles, overalls and wet weather gear. Two-way radios may also be used for communication.
