Find out how 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: Only applies in the Perth Metropolitan in declared drainage areas.
- Residential: 1 SIC per lot.
- Non-residential: 1 SIC + 1 SIC per 350m2 of lot area.
- Schools and universities on lots less than 3 hectares: 1 SIC + 1 SIC per 350m2 of lot area.
- Schools and universities on lots greater than 3 hectares: 1 SIC + 1 SIC per 350m2 of lot area up to 3 hectares and 1 SIC per 1250m2 of lot area over 3 hectares.
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.
