One of the most common problems that bore owners complain about from time to time is reduced bore yield. Reduced bore yield means that the volume of water in the bore is less than the usual amount. Reduced bore yield can affect crop production and yield for farmers who rely on the water for agricultural use. Here you will learn some of the common causes of reduced water yield in your bore and the measures that you can take to resolve the problems.
Faulty pump or piping system
The water level in your pump may still be the same, but the amount delivered by piping system may be less than expected. This can be due to faults in the pump or the water system. The most common type of fault would be a worn pump impeller. The impeller's primary role is to increase the pressure and flow of water. When it is worn, it won't be able to deliver on this task, and the result will be reduced water yield. Also, if the pipes supplying water from the bore are leaking, the amount of water received will reduce.
Inspect your pump and piping system if the water pumped from the well to the site reduces in volume. A worn propeller should be replaced to restore the proper functioning of the pump. If you have any leaking pipes, they should be repaired by an experienced contractor.
Mineral scale buildup
The accumulation of mineral scale on the bore casing or pump screen can significantly affect the flow of water from your well, and this will lower its yield. Also known as incrustation, mineral scale buildup can be identified by inspecting plumbing fixtures, bore casing, and pump screen for signs of scale. Proper inspection of the bore and pump can be carried by a professional contractor.
After determining that the cause of low water yield is mineral scale, the bore, plumbing fixtures, and water pump will be cleaned to get rid of the scale. The water should be treated using techniques such as acid and chemical treatment to prevent further formation of mineral scale.
More bores in the area
You may notice that the water level in your bore reduces after additional bores have been dug in the area. This is usually due to increased use of groundwater. Although this may not necessarily mean that your bore will dry out, you may be receiving less water in your home or farm than expected. You can talk with your neighbors with the help of an experienced bore water drilling contractor and resolve to reduce the pumping rates so that you can all have water for use.
These are some of the most common problems that may cause a drop in the water yield from your bore. Contact a professional bore contractor if you are unable to identify or resolve any problems with your bore.
