Practical Guidelines for Test Pumping in Water Wells (ICRC, 2011)

Pumping tests are a practical way of obtaining an idea of the borehole’s efficiency and its optimal production yield. Much of the specialized knowledge and technical expertise needed for this purpose can be gained from the standard literature. However, field operations in remote areas or in difficult conditions often require flexibility and imagination in avoiding or solving technical problems. These guidelines are intended mainly as a practical tool and
therefore contain a minimum of theory. They are aimed at water and habitat engineers working in the field who are undertaking or supervising borehole drilling or rehabilitation
programmes and are not conversant with pumping test procedures.

    Borehole Drilling and Rehabilitation Under Field Conditions (ICRC, 2011)

    Constructing, or repairing, boreholes requires specialized knowledge and technical expertise, much of which can be gained from the standard literature; but field operations in remote areas or in difficult conditions often require flexibility and imagination in avoiding and solving technical problems. This review is intended as a decision-making tool to assist in making cost-effective choices between borehole drilling methods, and in deciding whether to drill new boreholes or rehabilitate existing sites.

    UNHCR Sample ToRs for Hydrogeological Surveying (UNHCR, 2015)

    These sample terms of reference may be used should WASH actors working in refugee settings with to engage the services of a Consultant to carry out hydrogeological surveys of pre-selected areas. The terms of reference cover the following areas…
    Evaluating the groundwater situation based on compilation of existing relevant data (e.g. drilling logs) with additional classical hydrogeological field data collection (e.g. survey of water points, water levels, water quality) leading to the identification of favourable exploration zones
    Carrying out groundwater exploratory field geophysical investigations to identify exact drilling locations, and
    Supervising the drilling process and on the spot reporting on the progress.
