The infrastructure growth charge (IGC) is a contribution towards the capital investment we have made in bulk infrastructure to provide services to new or existing customers who increase their demand on our services.
Through the IGC, the cost of increasing the capacity of our bulk infrastructure is paid for by those who increase demand on the system now, rather than by existing customers or future generations.
Without the IGC, we would need to recover a greater proportion of our growth-related capital investment costs through our operational charges. This would cost all customers a lot more for their water and wastewater services.
