Habitat for Humanity Kenya is seeking to hire a Consultant/Consulting firm with the capacity to execute the following tasks:

1. Conduct environmental and social impact assessment for drilling of 3 new boreholes.
2. Provide drilling supervision for three boreholes, develop BoQ for equipping of three new boreholes and for rehabilitating 3 existing wells.
3. Background and Rationale

Habitat for Humanity Kenya (HFHK) was established in 1982 as a not-for-profit, non-governmental organization with the goal of enabling low-income families access decent and affordable shelter. It is an affiliate of Habitat for Humanity International (HFHI) and is governed by the National Affiliation Agreement of 2019. The organization’s approach has evolved from direct provision of homes to families with access to land, to providing support and capacity building to community level structures as a catalyst for transformation. In the last 40 years, HFHK has supported more than 345,000 families across 9 counties in Kenya through housing micro-finance and direct construction.

Currently, HFHK is operational in Laikipia, Homabay, Kisumu, Tana River, Machakos and Makueni counties under a Strategic Plan (2020-2025) which outlined four programmatic areas, namely: Financing for Owner-led Construction (FOC); Settlement-Based Practice (SBP); Secure Land Tenure (SLT); Disaster Risk Reduction & Response (DR3).

HFH Kenya is implementing a 39-month project to Improve the resilience to climate change for rural people in Solio settlement scheme, Laikipia county. the 3-year and three months project aims to rehabilitate non-functioning boreholes in 4 villages, construction of 3 new boreholes and four 1,000m3 water pans to support farming activities, identification and provision of access to financial services and capacity building of community members on financial skills to ensure good management of income from agriculture and other activities and to promote climate change adaptation technologies at the community level and finally the promotion of WASH best practices in the community.

1. Purpose and Objectives

The main objectives of this project are:

1. To conduct an Environmental and social Impact Assessment for drilling of 3 new boreholes within 3 villages (Solio Village 5, 6 &7) and acquisition of NEMA Licenses for the works and WRA authorization to drill the 3 sites.
2. To conduct supervision of the drilling process on the 3 new boreholes and to develop BOQ’s for equipping three new boreholes and three existing boreholes for rehabilitation.
3. Project Location

The assignment will be implemented in 4 villages within Solio settlement: Village 3 (Bahati), 5 (Mathingira), 6 (Mukandamia) and 7 (Baraka).

1. Scope of work.

ESIA

To ensure that a comprehensive study in the focus survey area and assessment is carried out, the following tasks are necessary:

To provide a comprehensive description of the project and the surrounding environment, specifying any information necessary to identify and assess the environmental and social effects of the project. This includes project objectives and information on:

• Rationale for the project and background,
• Activities and features which will introduce risks or generate impact (negative and positive) on the environment.
• The ESIA study shall include an assessment of the context, components, and activities of the project. Which include a survey on the surface hydrology of the area to confirm the implications of project actions on downstream areas and potential environmental and social impact of the project on Solio settlement scheme villages 3, 5, 6 & 7.
• Submit ESIA report approved by NEMA to HFHK.
• NEMA License Application and follow-up.
• Acquisition WRA Authorization to drill and abstraction permits for the 3 new boreholes.

Deliverables and Timing – ESIA

The consultancy is expected to start working on the assignment on 8th August 2024 for a duration of one month. Before heading out to honor the assignment, the consultant is required to submit an inception report and defend the delivery plan through presenting to HFH Kenya management team as shall be scheduled by HFH Kenya during contracting of the assignment. The consultant is expected to work very closely with the HFH Kenya management, HFHK Laikipia region field officers, Laikipia County government, Water Resources Authority, NEMA, Project Steering Committee and local national government administration officials in carrying out the assignment. The deliverables of this assignment are as follows.

1. Inception report describing in detail how the consultant plans to execute the key deliverables.
2. ESIA reports for the 3 borehole sites. These must be accompanied by a comprehensive environmental management plan.
3. A detailed and clear mitigation plan to prevent adverse impacts from happening and to keep those that do occur within an acceptable level.
4. Application to secure relevant government permits-NEMA License and WRA permits.

Scope of work – drilling supervision of 3 new boreholes and Development of BOQs for equipping three new boreholes and rehabilitating three existing boreholes.

• Developing Bills of Quantities (BOQs) for rehabilitation of 3 existing water systems in the 3 villages and drilling of 3 new boreholes that will be used in seeking quotations from prequalified contractors during bidding process, as well as developing the contract document and specifications.
• Supervise the drilling of 3 new boreholes and ensure the boreholes are drilled and completed according to stipulated technical specifications (Hydrogeological Survey Report to be provided later) and to sound professional standard, including the geological borehole logging and documentation of pumping test according to standard formats.
  • Supervise and document daily the drilling, development, test pumping and hand-in a daily drilling progress report to HFHK.
  • Ensure that the drilling contractor does water sampling, geological logging and water quality analysis (chemical and bacteriological).
  • Adapt the general well-design according to the specific conditions, basing it on the geological log and on the results obtained from the pumping test.
  • Supervise installation of screens, casings, gravel pack, impermeable seals, well-heads etc. Ensuring that the recommended drilling depths, design and materials are followed and propose and carry out quality control measures upon well-completion, e.g. borehole camera inspection.
  • Prepare a detailed borehole completion report, with all necessary recommendations e.g. pump capacity, optimum depth of installation, periodic water quality analysis according to the standard format.
  • All these documents shall be summarized in a Phase 3- Drilling Report, which will also include a quality control review of the drilling report from the drilling contractor.
  • Compile the Phase 1, Phase 2 and Phase 3 reports into a comprehensive final report (2 hard copies plus softcopy including all the raw data) and submit to HFHK.
• Obtain all certificates and acquired documentation from the driller and submit to HFHK at the end of the project.

Development of BOQs for Rehabilitation and Equipping.

Step 1 – Desk review of existing boreholes assessment report provided by HFHK Inclusive of camera inspection report
