Stormwater disposal collects rainwater from catchment areas such as the roof and paving surrounding the dwelling. There are two types of stormwater disposal.
If the local council has provisions for connection into the shire stormwater system, it will be made a condition of the building permit that the builder is required to complete the connection. Generally, the local shire will require the owner to pay a contribution fee relating to the supply and installation of an approved spigot/s within the lot/s.
To retain stormwater on site an Engineer will design a proposed stormwater system which must be submitted and approved by the local shire. Soil conditions and the amount of paving will affect the design of the stormwater system and therefore the volume and size of the soak wells and therefore the price.
