Here you will find information about the way infrastructure contributions are calculated for green title subdivisions
Water supply, wastewater and drainage contributions are based on the provision of a base level of service to each new lot.
Standard Infrastructure Contributions (SICs) are payable when there is a subdivision that requires any combination of water, wastewater and drainage services. They are applied as follows:
Water – 1 SIC per lot for all land use types
Wastewater – 1 SIC per lot for all land use types
Drainage – SICs only apply in the Perth Metropolitan declared drainage areas:
- Residential – 1 SIC per lot.
- Non-residential and schools and universities on lots less than 3 hectares – 1 SIC per lot + 1 per 1250m2 of lot area and part thereof.
- Schools and universities on lots greater than 3 hectares – 1 SIC per lot + 1 SIC for each 1250m2 of the lot area and part thereof.
Infrastructure contributions are not payable on the creation of public open space and crown reserves, as there is no inherent demand for a water service.
The above information is a guide for calculating the level of infrastructure contribution requirements for your subdivision.
