Unfortunately the majority of bores in Melbourne will have salinity issues to a certain degree with the water requiring treatment in one form or another. Only a few areas though are lucky enough to have aquifers that produce good enough water to pump straight onto the garden. It is therefore recommended not to install a pump on your bore untill you have the results of your water analasys (cost included with Southern Rural Water license fees).

One of the main issues with salinity is that it builds up in the soil over a period of time especially when there is inadequate rainfall to flush the salts out of the soil. There are several ways to deal with water high in salinity.

One of these is simply to mix or 'shandy' it with rain water either in tanks or a dam.

Another method is to fit a magnetic water conditioner such as those produced by Delta Water Solutions (for whom we are an agent). Magnetic conditioners do not remove or lower levels of salts in the water. They simply ionize the molecules so-that they behave differently and are not retained in the soil. Unfortunately these conditioners are only viable for electrical conductivities (EC) of up to 6000.

Note to all the sceptics out there that think these magnets are 'hocus-pocus': we have one installed on our bore in Healesville which has an EC of 3500. Before the conditioner, we lost a few plants and our garden was looking pretty sad. With the conditioner, our garden has taken off and is looking great. I would not be recommending these units if they didn't work.

For very high salinity and for the best quality water a de-salination unit will have to be installed. Whilst these units are costly to install, once they are running, you are guaranteed a constant supply of quality water which can be used for almost anything. A few issues to be aware of with de-salination units are that first of all you will need a storage tank and pressure pump for the processed water as the output of a de-salination unit is very low and not sufficient to put straight onto the garden. Another is that you need some way of disposing of the by-product or brine that is left over from the process. This is fine for people living in the cities connected up to the sewer system, however those in rural areas need to be a bit more creative. One method is to make use of shallow poly lined evaporation ponds. For de-salination equipment suppliers and installers, check the links on the Pumps page.

We have a fairly good idea as to which areas have good water and which areas have bad water (high salt levels) and we will try our best to inform customers of what to expect before we drill. Beware of drillers who will not divulge this information as we all know what to expect in the areas we drill.
