CALL FOR EXPRESSION OF INTEREST

CONSULTANCY TO CONDUCT A FEASIBILITY AND HYDROGEOLOGICAL STUDY ON COMMUNITY-DRIVEN MODELS FOR WASH IMPROVEMENT IN KATONDO SETTLEMENT IN KABWE DISTRICT & MUKUBWE WARD IN NGABWE DISTRICT

TERMS OF REFERENCE
1.      BACKGROUND

Habitat for Humanity Zambia (HFHZ) is planning to implement a WASH project in Katondo community of Kabwe district, and in the communities of Ngabwe district between 1st September 2024 and 31st August 2027. A proposal for this project will be submitted to the Federal Ministry for Economic Cooperation and Development of the Federal Republic of Germany (BMZ) in collaboration with the Stiftung der Deutschen Lions (SDL, Lions Foundation Germany).. In order to ensure a relevant, effective, efficient, coherent, sustainable, and impactful project, the principal will commission a Feasibility and Hydrogeological Study. These Terms of Reference (TOR) explain the purpose of the study, required qualifications, experience, and references for the consultant, and the deliverables. The study is in two Sections—feasibility and hydrogeological.

2.      FEASIBILITY SECTION

The study will analyse the feasibility based on the Project Concept, Needs Assessment Study and the Theory of Change (ToC), finances and time availed for this project. In doing so the study will examine and verify the Project Concept, identify weaknesses and provide recommendations for optimisation.

2.1 Purpose of the Study

The purpose of the study is to:

a)     assess the project objectives, merit and worth of the project based on OECD DAC Evaluation Criteria (cf. bengo´s “Guide to conducting feasibility studies”);

b)     provide a sound, empirically verified basis for the project, identify and verify material assumptions and prerequisites for project success, identify risks and risk mitigation strategies based on the OECD DAC Evaluation criteria;

c)      present project context on community-, district, regional-, and national level, including relevant baseline data:

• Ground conditions and environmental factors (e.g. presence of rocky ground, high ground water table, etc) which may affect decisions on appropriate sanitation options.
• Key hygiene practices in terms of water needs and sanitation habits.
• Cultural habits among the local population that might affect their hygiene/sanitation preferences.
• Specific vulnerabilities, for example, disabilities and people with specific diseases to tailor WASH services accordingly.
• Local capacity to lead or support the WASH interventions.
• Water availability in adequate quantity with a focus on the household level, school facility level, and health facility level, water quality from user perception and potential sanitary risks
• Challenges associated with the collection and storage of water.
• Access to toilets, usage of toilets, access to other sanitary services like waste disposal, and sanitary conditions of the village.
• Prevalent hygiene practices such as handwashing and disposal of child faeces and the impact of water bone diseases on hygiene practices
• Assess WASH management practices, gaps in the target locations.

d)     provide specific recommendations for the impact matrix and project activities.

e)     optimise the project concept, improve quality, and maximise impact and sustainability.

2.2 Deliverables:

a)     Proved a tentative work plan indicating the maximum number of days required to undertake the assignments taking into account the review period needed to be given to the principal.

b)     Inception report, including methodology with proposed data collection instruments.

c)      Presentation of preliminary results in preliminary report format and PPT, to be delivered after data collection is closed.

d)     Discussion of the preliminary report with the principal, HFHD and SDL to look at any necessary adjustments.

e)     Report with annexes should not exceed 40 pages (excluding annexes).

f)       Closing presentation (PPT and study to be shared in advance and then discussed in a meeting).

g)     Final versions of the report and PPT including adjustments as discussed in the closing presentation.

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.
