Alternative Bore-Water Supply
Description
Having a back up supply from a bore is very handy. Bore water can be used to supply yard wash water directly or shandied in with re-used yard wash water destined for disposal.
In many areas the water temperature is frequently constant throughout the year (about 16 - 18C) so can use bore water to supply the pre-cooler too.
Set-up costs are high - bore (about $5,000), submergible bore pump ($2-5,000), tank ($3,500), electrical and piping ($1000). Licensing from the water authority is generally required to construct a bore and then use water from a bore for dairy wash down.
Tips on Getting the Best Result
Fill header tank on off-peak power / wind mill.
