A baseline (or baseline demand) is the amount of water and/or wastewater a property can use over a 12-month period. The period is most often our financial year (July-June).
For every property that connects to our network we need to plan ahead, without reducing the level of service our existing customers receive. If you grow your business through an increase in water and wastewater use, we must grow our infrastructure to accommodate your needs. Each property has an agreed capacity of water/wastewater services that they use each year without incurring an Infrastructure Growth Charge (IGC) – we call this a baseline. If the baseline is exceeded, you may incur additional IGCs relative to your increase in demand above the baseline.
