GENERAL REQUIREMENTS

The Programme: Agricultural Producer Support and Development is responsible for extension services and on – going support of agricultural projects within the Western Cape. It also aims at encouraging farmers to excel in the farming sector by paying special attention to their farming practises and opening opportunities for growth.

Lenqua Trading (PLAS) is a commercial farming enterprise producing vegetable crops and grazing fodder under centre pivot irrigation.  The farm is situated approximately 40km’s north of Piketberg on the R366.  The farm only has water for 18ha whilst the water allocation for the farm is 66ha.  It hence requires additional boreholes to increase production in order for the farm to become sustainable.

The scope of works will include:

  1. Hydrogeological Groundwater Surveying;
  2. Conduct a Geohydrological study on the farm in order to assess the availability of alternative aquafers that may provide alternative sources of groundwater for irrigation purposes.
  3. Site verification and pegging borehole positions
  4. The successful bidder is to prepare hydrogeological survey reports in conformity with the provisions of the rules and procedure outlined by the Water Resources Management Authority, including the following:
    • Site Name, Location and GPS readings.
    • Geology and hydrogeology.
    • Present sources and status of the existing water supply.
    • Existing borehole data information.
    • Geophysical data and analysis
  5. Analysis of delivery test information and recommendation of borehole development.
  6. Geotechnical support during drilling

The following reporting requirements should be noted:

The format of writing the Hydrogeological Investigations Report must be as described in the Second Schedule of the Water Resources Management Rules, 2007. Such a report must consider the following (verbatim):

  • Name and details of applicant
  • Location and description of proposed Activity
  • Details of climate
  • Details of geology and hydrogeology
  • Details of neighboring boreholes, including location, distance from proposed borehole or boreholes, number and construction details, age, current status and use, current abstraction and use.
  • Description and details (including raw and processed data) of prospecting methods adopted, e.g., remote sensing, geophysics, geological and or hydrogeological cross sections. Hydrogeological characteristics and analysis, to include but not necessarily be limited to the following:
    1. Aquifer transmissivity
    2. Borehole specific capacities
    3. Storage coefficient and or specific yield
    4. Hydraulic conductivity
    5. Groundwater flux
    6. Estimated mean annual recharge, and sensitivity to external factors
  • Assessment of water quality and potential infringement of national standards.
  • Assessment of availability of groundwater.
  • Analysis of the reserve.
  • Impact of proposed activity on aquifer, water quality, other abstractors, including likelihood of coalescing cones of depression and implications for other groundwater users in any potentially impacted areas.
  • Recommendations for borehole development, to include but not limited to, the following:
    1. Locations of recommended borehole(s) expressed as a coordinate(s) and indicated on a sketch map
    2. Recommendations regarding borehole or well density and minimum spacing in the project area
    3. Recommended depth and maximum diameter
    4. Recommended construction characteristics, e.g. wire-wound screen, grouting depth
    5. Anticipated yield

Any other relevant information (e.g., need to monitor neighboring boreholes during tests). This report should be written to cover each of the above, insofar as data limitations allow. The report also must include maps, diagrams, tables and appendices as appropriate.
