Annual service charges are raised based on the availability of the service to the property, and may include charges for water, wastewater and drainage services. Charges help cover the costs of providing clean and safe drinking water in Western Australia; taking away wastewater and disposing of it in an environmentally appropriate way; and removing stormwater through drainage services. Drainage charges apply only to metropolitan customers in the Declared Drainage Areas serviced by Water Corporation. Drainage services provided by Water Corporation in regional areas are fully funded by the State Government.
