The story of the Olorombo community is a deeply moving one. Before committing to this project, our team conducted extensive field surveys across Oyo State, visiting nearly 20 villages to understand the most urgent water needs and long-term risks faced by rural communities.

What stood out about Olorombo was the compounding impact of water scarcity. The community’s lack of reliable access to clean water was not only posing serious health risks, particularly from waterborne diseases, but also threatening their primary source of livelihood. Olorombo is a farming community, and water is especially critical during the dry season when crops, food security, and household income are most vulnerable.

At the time, residents relied largely on shallow wells. These wells were inconsistent, often drying up entirely, forcing families, particularly women and children, to travel long distances in search of water. Without intervention, the consequences of this ongoing scarcity risked becoming severe and long-lasting.

Rethinking Sustainability Beyond Solar Technology

In previous projects, we have successfully implemented solar-powered boreholes, leveraging renewable energy to ensure continuous water supply. However, experience has taught us that sustainability must be rooted in local realities, not only good intentions.

Despite strong community education efforts, solar-powered systems presented challenges in several villages. In Olorombo and similar areas, inconsistent sunlight limited the ability of solar panels to adequately charge batteries. This resulted in disrupted water supply, increased maintenance costs, and dependence on external technical support.

These lessons became a turning point. For Olorombo, we intentionally shifted our approach, prioritizing reliability, ease of maintenance, and long-term community ownership over technological complexity.

From Assessment to Installation

Based on our findings, we selected a sustainable hand pump borehole system, a solution designed to function independently of fuel, electricity, or solar energy.

Drilling took place on 12 November 2025, using a Percussion Air Rig, a method well-suited for hard rock formations. A total depth of 60 meters was drilled, at which point fractured bedrock was intercepted and clean water was successfully accessed. The drilling process was completed in within a day.

To safeguard water quality over time, PVC casing was installed from the surface down into the bedrock. This critical step prevents surface runoff and contaminants from entering the borehole, significantly reducing long-term contamination risks.

We installed an Aquadev Mark II hand pump, chosen for its durability, efficiency, and suitability for rural settings. Key features include:

• Ability to pump water from depths of up to 80 meters
• High discharge rate of 900–1,200 liters per hour
• Designed to last up to 15 years with basic maintenance
• 100% locally repairable, with all parts readily available in Ibadan markets

Installation was completed on 18–19 November 2025, with all components safely assembled and tested.

A concrete fetching platform was constructed beneath the pump, adhering strictly to safety and hygiene standards. Importantly, local bricklayers and masons from the Olorombo community were engaged for this work—reinforcing skills transfer, economic participation, and a shared sense of ownership.

The Impact: Clean Water, Productivity, and Dignity Restored

Today, the hand pump borehole provides clean, reliable water to over 200 households in Olorombo and neighboring communities, surpassing the original estimate of 100 households.

The impact has been immediate and tangible:

• Households now have consistent access to clean water for drinking and domestic use
• Health risks associated with unsafe water sources have been significantly reduced
• Palm oil producers in the community now have a dependable water supply, improving production efficiency and overall productivity
• Time previously spent searching for water can now be redirected toward education, farming, and family life

The community has expressed deep gratitude and collectively agreed to take responsibility for maintaining and protecting the borehole to ensure it serves future generations.

Looking Ahead: Building for Longevity and Replication

The Olorombo project reinforces a core lesson in our work, true impact lies in sustainability, community ownership, and context-aware solutions. By choosing a system that aligns with local conditions and skills, we’ve laid the groundwork for long-term success.

Looking ahead, we aim to:

• Continue monitoring the borehole’s performance
• Support community-led maintenance practices
• Apply these lessons to future water projects across Oyo State and beyond

Clean water is not just an infrastructure project—it is a foundation for health, dignity, and economic resilience. The Olorombo community’s journey is a reminder that when solutions are built with communities, the impact endures.
