A bit about bore Construction

 

The first step is deciding on a suitable site with good access for the drill rig which is mounted on a heavy rigid truck. Usually the best place for a bore is close to power, and out of the way. A lot of people decide to get a water diviner to choose a good spot.

We then set the rig up and start drilling.

Once we have intercepted suitable water and all cuttings have been cleaned out, the casing is installed and a water sample can be collected for testing.

After the casing and screens have been installed a gravel pack is placed between the outsite of the casing, and the inside of the hole.

The production zone is completely sealed off with a bentonite clay seal.

bore development is the next step. This may take from half an hour to several hours, depending on how fine the sand is in the aquifer. Towards the end of this stage the bore flow is measured.

On completion the space between the casing and the bore hole is sealed with grout. Sealing from the surface down to the first impermeable layer. This prevents contamination from surface runoff or sub surface contamination from septics.

the land holder receives a copy of the bore log, which states the standing water level, and all other relevant details required by State Water in NSW and the Department of Environmental Resource Management in QLD.
