3.      HYDROGEOLOGICAL, GEOPHYSICAL AND WATER SUPPLY SECTION
The project plans to drill new boreholes and upgrade existing hand pump boreholes to solar water schemes in public schools in selected areas of Katondo informal settlements in Kabwe district and Mukubwe ward in Ngabwe district. The target volume of water to supply to each person per day is 20 litres.
The drilling of the new borehole works will include hydrogeological and geophysical investigation—identification of borehole sites that have sufficient water aquifer, drilling of 8-inch internal diameter borehole, conducting of pump testing, water quality tests and equipping them with solar submersible pump and power system. The upgrading of the existing water points (hand pumps) will include conducting water pump tests, water quality tests and equipping them with solar submersible pumps and power systems.
In addition to groundwater supply works the project has plans to construct water storage infrastructure which shall be connected to the Lukanga Water, Supply and Sanitation Company (LWSSC) existing municipal water supply pipeline to service storage tanks at water kiosks in the community and school tank stand elevated at 6m.
3.1 Purpose of the Study
The purpose of the study is to:
a)     describe the two areas (Mukubwe ward and Katondo informal settlement) in terms of a baseline description of the geology, topography, soils, existing water points, water quality and sanitation facilities.
b)     describe the existing boreholes and dug wells’ hydrogeological conditions. The hydrogeological conditions being:

Aquifer and borehole yield through conducting pump testing/drawdown analysis,
Baseline water quality status i.e., physical, chemical, and biological status and pollution sources with proximity.
Existing borehole and well structures information indicating the depth of borehole, type and condition of casing pipe, gravel pack status, sanitary seal and bottom plug status and soil collapsed sections if any;
Source water protection: wellhead protection areas, significant drinking water threats and existing conditions/issues.
Registration status with regulatory body such as Water Resources Management Authority (WARMA) and number of beneficiaries on each existing point.

c)      For new boreholes sites, conduct a hydrogeological and geophysical investigation to describe the site’s aquifer properties, aquifer groundwater quality (chemical, physical and biology) and quantity, site soil types and collapsing capability, groundwater levels, groundwater flow direction, and ecologically significant groundwater recharge areas.
d)     Perform a risk assessment of the sites’ aquifer contamination potential and also indicate possible sources of contamination.
e)     Recommendation from findings on which site to drill new boreholes and which existing boreholes/wells can be upgraded into water schemes.
f)       Recommendation from findings on which cost effective water treatment method to be used for the existing and proposed new boreholes.
g)     Conduct pressure testing and provide water pressure information of the selected existing LWSSC water supply pipes lines to the proposed sites of the storage tanks at the school and community to be elevated at approximately 5-6m height.
h)     Recommendations from the pressure assessments of an appropriate height the storage tanks are to be placed and times of each day the existing municipal pipe contains the required pressure to fill up the elevated storage tanks.
3.2 Scope of Works
The Consultant is expected to use both secondary and primary data in the exercise, Secondary data will involve desk study of available information/data on existing boreholes, drill logs, reports and maps and periodic water pressure readings for the existing pipes from LWSSC. While primary data will be obtained by carrying out hydro geophysical measurements on existing boreholes and new sites for groundwater works and for municipal water supply dependant areas, pipe pressure testing of the service lines shall be conducted. During the study, they will need to use the necessary hydrogeological surveying equipment, the instrument, which distinguishes between clays and freshwater by resistivity profiling and vertical electrical soundings. The outcome of the consultancy will be a detailed hydrogeological investigation report giving details of the findings and recommendations.
3.3 Approach of Works
The hydro-geological/geophysical investigations will be carried out in a multi-step approach:
a)     Desk study: Review of existing data for both of the pre-selected sites in Mukubwe ward and Katondo informal settlement, water resource trends, topographical maps, satellite images, existing studies and borehole site investigations in the area, geological reports and maps (if available), borehole records and for municipal supply; periodic readings, water quality test reports and maps of the service lines to the selected areas etc.
b)     Hydro-geological fieldwork: Detailed reconnaissance survey of project-selected areas. (GPS co-ordinates/, water level measurements, water yield, condition of these boreholes, usage and performance where applicable) inspection of geological and structural characteristics of the investigated area; verification of existing data and findings.
c)      Pump tests and geophysical investigations, resistivity profiling and vertical electrical soundings.
d)     Water quality assessments, describing the physical, chemical and biological status of the water both ground and municipal water.
e)     Analysis of hydro-geological/geophysical data.
f)       Compilation, analysis, and evaluation of the gathered data and information.
g)     Site selection (new boreholes and existing for upgrading)
h)     Reporting with findings and recommendations
i)       For Municipal water supply earmarked areas, pressure testing of pipes shall be conducted to marry findings with the existing pressure readings availed during desk study.
