Is Your Borehole Water Too Salty?

If you are looking for a way to reduce your dependence on main waterlines, one option that you could consider is creating a borehole. Taking water from a borehole can be a highly effective long-term solution. Meeting your water needs by digging a borehole will provide you with plenty of water, but the water from the ground may need further treatment before being used on your property. Without treatment, the water could be dangerous for you or your stock to drink. It may even be too high in salts for use in irrigation. Many landowners find that it is best to invest in a bore water desalination system to make full use of the water taken from their property.

How much salt is too much?

Bore water desalination can remove most salt, but it must be understood is that no process can completely extract all the salt from the water. Salinity is often measured by looking at the total dissolved solids, or TDS, of the water, measured in milligrams per litre. To see how the water from your borehole could be used, test the water, and understand what the acceptable limits are for each way the water might be used. You might find that bore water desalination isn't needed, or perhaps, that even after desalination, there are some ways that your water cannot be used. Once the TDS exceeds 1000 mg/L, the taste is likely to be unacceptable. Other problems, including excessive scaling or pipe corrosion, will become noticeable as the salt concentration increases.

What is involved in bore water desalination?

Desalination is the process of extracting salts from water so the water can be used effectively. There is a range of ways desalination can be achieved. One of the most popular desalination methods is reverse osmosis. Reverse osmosis employs a semi-permeable membrane and uses an external pressure to drive the water through the membrane, leaving the salt behind on the other side.

Buying a bore water desalination system

If you decide that desalination is needed for your borehole water, it is best to discuss your requirements with your local supplier. They will be familiar with the local water profile and how the system could fit into your situation. The supplier may also help you arrange a laboratory test for your water. With the suppliers' help, you can be confident that the bore water desalination system you purchase will be appropriate for your needs and achieve the results you need.
