Nairobi — Thousands of households in Machakos County are set to benefit from improved water access following the completion of seven sand dams along the Maindandu River, a project supported by the APA Apollo Foundation and partner organisations.

The dams, constructed along a 14-kilometre stretch of the river, are designed to provide reliable year-round water for domestic use, irrigation, and livestock in an area that has long struggled with scarcity. The initiative brings the total number of sand dams completed by the foundation to 47 across the country.

Each dam will be fitted with a solar-powered pump and a permanent reservoir to support small-scale farming and household consumption. The APA Apollo Foundation estimates that at least 15,000 residents will directly benefit from the infrastructure.

The project was implemented in partnership with the Asian Foundation Kenya, District Grand Lodge, I&M Foundation, Manav Foundation, and Utooni Development Organisation, which handled engineering and community engagement.

Local farmers say the new structures are already boosting agricultural productivity by enabling irrigation beyond the rainy season. Residents also expect reduced time spent fetching water, improved household food security, and enhanced resilience to drought.

Sand dams, which store water within accumulated sand, are increasingly being adopted in arid and semi-arid regions as a cost-effective method of water conservation. Experts say such systems help recharge groundwater, reduce soil erosion, and support ecological restoration.

The organisations involved say the focus will now shift to ensuring long-term maintenance of the water systems and supporting communities to maximise the agricultural and economic benefits.
