Waterwells can become clogged up over a period of time due to iron bacteria fouling and deposition of minerals within water bearing fractures. Well screens and filter packs also clog and inhibit the ingress of water. Generally after progressive deterioration the water from the well becomes turbid which increases treatment costs, the well yields less water increasing drawdown and therefore increasing pumping costs against a higher head and eventually lead to the failure of the submersible pump.

Wells that have been unused for a period of time may also need cleaning before being put back into use.

There are various methods of rehabilitating a well depending on what is causing the problem. The well may need scrubbing, treating with chemicals, acidising or treating with gas injection.

If you have a well that is not producing the volume of water that it used to or if you have an old well on your property that you would like to bring into service, Drilcorp will be happy to quote for carrying out the work.

Iron Oxide Sludge Buildup

When iron oxide residues build up in the borehole, production decreases and maintenance costs spiral out of control.

The slippery orange iron deposits are due to the conversion (oxidization) of dissolved iron by naturally occurring bacteria is not only unpleasant but more importantly, indicative of a system that is steadily becoming constricted, inefficient and expensive to maintain.

This is a natural process and cannot be eradicated but it can be controlled – Boresaver Liquid- can remove the iron oxide build up in an environmentally friendly way and is government approved for use in potable water supplies.
