The plan details the water supply and/or sewerage developer charges to be levied on development areas utilising a water utility’s water supply and/or sewerage infrastructure. Developer charges cover part of the cost of providing water supply and sewerage infrastructure to new development and redevelopment. Note : The developer charges for water supply and sewerage in the new Development Servicing Plans include a cross subsidy. A cross subsidy means a reduction in the calculated developer charge. It is income that Council does not raise from developer charges that has to be raised from annual water and sewer bills. On average, the cross subsidy adds $0.91c each year to a typical sewer bill and less than $0.81c each year to a typical water bill.
