• Siting The Borehole

    Groundwater cannot be found everywhere. If properly located, a borehole can provide a good supply of water. If it is not, it will fail and thus result in wasted investment.

    There are two common techniques of siting in Zimbabwe, the Traditional Method and the Geological survey Method.

    The traditional method or water dowsing /divining makes use of the Y branch, a water-filled bottle, L rods, pendulums etc. This method is used extensively in Zimbabwe and is surprisingly effective.

    Good water dowers with experience are able to predict breaks, depths and expected yields to a great degree of accuracy. One must use caution in high mineral bearing areas as minerals in the earth crust can mimic the feel of breaks and errors can occur.

    Geological surveys make use of resistance mapping to locate flaws and soft zones in the earth crust in which water may be resident. This method of surveying, being scientific is usually more expensive than the traditional method as more manpower is required and the time needed can be extensive.

    Consider the following:

    1. Pollution sources
    2. Location
    3. Access
    4. References of the siter
    5. Siters statistics of success
    6. Guarantees and money back
    7. The yield and depth of other boreholes in the area
    8. Securing the hole in the future
    9. Distances from both power and water points

    Insist on a site report including a location sketch, GPS coordinates, breaks, expected water yield and depth. This information is needed for your ZINWA drilling permit.

    Lastly, ensure your Dowser is readily available in case a decision to drill deeper is required. Professional dowsers make themselves available ‘with a warning’ and have no problem with this.
