  Background:

Mercy Corps has been present in Nigeria since 2012, focusing its interventions on humanitarian assistance, economic recovery and development, and conflict mitigation and peacebuilding. Considering the protracted conflicts between farmer and herder communities in Adamawa State, Nigeria, competing claims to land, water and other natural resources are at the root of these growing tensions. Indeed, pressure on natural resources has increased due to demographic growth, expanding human settlements, privatization of land, year-round farming practices, environmental degradation, and climate change. In many instances, traditional conflict resolution mechanisms that play significant roles in mitigating these resource-based conflicts locally have become overwhelmed. Besides, low levels of trust in authorities by communities due to widespread inaction, impunity, and perceived biases or reactive responses by the government to shared natural resource conflicts complicate the tensions further. Through funding from the EU, the International Organization for Migration (IOM), Search for Common Ground (Search), and Mercy Corps have designed a comprehensive and integrated approach (COMITAS) that builds on the comparative strengths of each organization to contribute to the mitigation of conflicts over natural resources between farmer and herder communities. This program is developed around 4 interconnected objectives: strengthen traditional conflict resolution; improve trust in authorities; enhance collaboration on natural resource management and improve intra and inter-communal perceptions.

Mercy Corps is leading the implementation of objective 3, which focuses on enhancing collaboration on natural resource management. Mercy Corps has supported the communities to formulate concrete action plans to improve resource management. The action plans build on existing local plans and integrate tools that are successfully being used in the local government area and are linked to the planning of natural and community resources at the grassroots level. The action plans form the basis of concrete actions and projects that will demonstrate the benefits of cooperation between and among communities, enhance trust, and support improved natural resource management. In this instance, Priorities from the plans have now identified Quick Impact Projects (QIPs)agreements through water infrastructure projects. The results of the geophysics survey proved that groundwater development through borehole construction is not viable, hence an alternative (Infiltration Gallery) was adopted to provide the community with a sustainable source of water; a concept that aims to collect the alluvial water from the riverbanks through a system of infiltration gallery and a collection well.

Objectives:

  • Facilitate NRM through groundwater development (Infiltration Gallery).
  • Create a sustainable source of water supply to reduce tensions in resourced-induced conflict-prone zones.
  • Collaborative use of natural resources for improved social cohesion.
  • Project Overview:
    • The project involves the construction of a water infiltration gallery to facilitate the collection and infiltration of water into the deep well for extraction through a solar-powered submersible pump and riser pipes.
    • The gallery will be designed to meet the specific requirements of the site and geophysical survey recommendations and ensure efficient water management.
  • Pre-Construction Phase:
    • Conduct a geophysical site survey to assess the location and conditions for the installation of the infiltration gallery.
    • Obtain all necessary permits and approvals from relevant authorities for the construction work.
    • Develop all appropriate quality assurance documents.

–     Location-specific working designs should be produced considering factors such as flow rates, depth of the well, geophysical survey outcome, and materials to be used.

  • Construction Phase:
    • Excavate trenches in the designated area for the installation of the infiltration gallery according to the approved design plans, dimensions, and geological features. Taking note of components such as perforated pipes, filter media, and casing in the water infiltration gallery and well according to the design plan.
    • Bore a hole wide enough to accommodate a 4 feet-reinforced circular or square culvert serving as a lining for the water collection well.
    • Construct the gallery well structure using appropriate materials (4-foot-in diameter reinforced concrete culverts) and techniques to ensure durability and functionality.
    • Install necessary filtration systems and drainage (appropriate screens of 6 numbers x 6 m length Upvc pipes 15 Bars) and adequately cover with relevant boulders and other aggregate sizes, and riverbed sand with relevant components to facilitate water infiltration.
    • Backfilling and Sealing: Backfill the trench and borehole with suitable materials to ensure stability and prevent contamination of the water source. Seal the well casing to prevent surface water from entering the well.
    • Testing and Monitoring: Conduct tests to ensure the proper functioning of the water infiltration gallery and well, such as water flow rate tests and water quality analysis. Implement a monitoring system to track the performance of the system over time.
  • Maintenance: Establish a regular maintenance schedule to inspect and clean the water infiltration gallery and well components, as well as monitor water quality and flow rates.
  • Conduct quality control checks throughout the construction process to ensure compliance with specifications.
    • Conduct pumping tests to ascertain submersible pump size and solar panel specifications.
    • Construct a fetching point fully tiled with 4 tap points, slopped at an appropriate gentle angle to facilitate emptying of runoff sand trap, seal, and floor.
    • Install a 10,000L PVC tank on a 1.5 m-high elevated platform.
  • Post-Construction Phase:

  • Test the functionality of the infiltration gallery to ensure proper water infiltration and drainage.
  • Provide training to site personnel on the operation and maintenance of the gallery.
  • Prepare a detailed report documenting the construction process and final results.
  • Health and Safety:
    • Implement all necessary safety measures to ensure the well-being of workers and site personnel during construction.
    • Comply with all relevant health and safety regulations throughout the project.
  • Project Management:
    • Assign a project manager to oversee the construction process and ensure timely completion within budget.
    • Maintain open communication with the client to provide regular updates on the progress of the project.
  • Deliverables:
    • Completed water infiltration gallery constructed according to approved design plans.
    • Documentation including construction reports, and test results.
    • Maintenance guidelines.
  • Project Overview:
    • The project involves the construction of a water infiltration gallery with a depth of 20 meters, as well as the installation of solar panels, submersible pumps, and storage tanks to support the water management system.
    • The gallery will be designed to efficiently collect and infiltrate water into the ground, while the solar panels, pumps, and tanks will provide energy-efficient and sustainable water management solutions.
  • Pre-Construction Phase:
    • Conduct a detailed site survey to assess the location and conditions for the installation of the infiltration gallery, solar panels, pumps, and tanks.
    • Obtain all necessary permits and approvals from relevant authorities for the construction and installation work.
