For essential service providers, high energy costs and unreliable power supply can quietly erode operational stability. Nowhere is this truer than in the water sector, where pumping, treatment, and distribution depend on consistent electricity. When the grid falters or bills climb, access to clean water is threatened.
This was the reality for Kikuyu Water and Sanitation Company. Relying on multiple boreholes to meet demand, the company faced unsustainable electricity costs and frequent interruptions from grid power failures.
Rather than continue down that path, Kikuyu Water made a bold but strategic move—investing in solar energy. What began as a small pilot project would soon spark a ripple effect of financial, operational, and community transformation.
Kikuyu Water did not dive into solar overnight. The company began with a single borehole pilot at Riu 1, analyzing performance carefully before scaling up. The results were immediate; significant cost savings, more reliable power, and a compelling business case to expand.
Encouraged by this success, the company rolled out solar installations across 4 other high-yield boreholes; twin-Island 1 & 2 boreholes and twin-Gichuru 1 & 2 boreholes. Electricity bills fell sharply, freeing up funds that could be redirected toward essential projects. The company used these savings to extend water lines into underserved areas, turning energy efficiency into a direct social investment.
The most powerful results were not just in reduced costs but they were in people’s lives.
Solar energy allowed Kikuyu Water to increase daily water production, reaching thousands of new residents in previously unserved communities. Service reliability also improved, with longer supply hours and fewer interruptions caused by grid fluctuations.
At the same time, the utility reduced its dependence on the national grid, contributing to lower carbon emissions and supporting Kenya’s climate goals. What started as a technical upgrade quickly became a story of community empowerment and environmental stewardship.
Transitioning to solar was not without challenges. Integrating modern solar systems with an aging, unstable national grid introduced new technical risks. Frequent voltage surges threatened to damage the expensive new solar inverters.
To safeguard its investment, Kikuyu Water installed protective equipment such as automatic voltage regulators and phase protectors, ensuring that the shift to clean energy would not be undermined by grid instability.
The lesson was clear: sustainable innovation must also be resilient innovation.
The utilities’ solar journey offers a practical model for other local utilities. Starting small, testing data, scaling up strategically, and reinvesting savings in the community, this is how real, sustainable transformation takes root.
At WASPA, we believe stories like this should guide the sector’s transition toward greener, smarter, and more resilient service delivery. As we champion these local success stories, we invite partners, investors, and development actors to join us in accelerating sustainable solutions across the WASH sector. Together, we can turn today’s small innovations into tomorrow’s sector-wide transformation.
