Water and Sewerage
Most rural properties have to provide for their own water supply and sewage disposal. This usually means rain water has to be collected in tanks or water has to be pumped from waterways or an underground bore. If water is already piped onto the property from elsewhere, find out where it comes from and check that there is an easement or permission that allows this to continue - even in summer dry periods.
Sewage disposal is often to a septic tank. Septic tanks need to be emptied periodically.
It may be that you will need to install a new water supply or sewage disposal system - especially if the property is bare land.
Check that any existing water supply and sewage disposal systems meet the required standards and actually work.
Rural landowners are responsible for the ongoing maintenance of water supply and sewage disposal systems - you'll need to know how to maintain pumps and clear blocked drains.
