Water scarcity represents the most critical development challenge facing Machakos County, with chronic insufficiency of reliable water supply for human consumption, livestock, and agriculture. The semi-arid climate and variable rainfall create persistent water deficits, while growing population increases demand.

Groundwater supplies constitute the primary water source for much of Machakos County. Boreholes and shallow wells provide household and community water access in areas where groundwater is accessible. However, groundwater quality varies, with some areas experiencing high salinity unsuitable for drinking or irrigation. Groundwater depletion from over-extraction threatens long-term availability in some locations.

Surface water sources including rivers and seasonal streams provide water during rainy seasons but disappear during dry periods. The Athi River, Mwea River, and other watercourses serve as water sources for riparian communities but are often dry for extended periods. Small water ponds and dams constructed during rainy seasons provide water storage but lose water to evaporation.

Water collection duties traditionally fall on women and children who travel significant distances to water sources. This labour burden limits time available for education and economic activities. Water carriage consumes substantial household effort, affecting productivity and quality of life.

Urban water supply systems serve Machakos town and other urban centres through piped networks managed by county or community water authorities. However, water quality, reliability, and affordability remain problematic. Piped water often faces contamination risks, irregular supply, and cost constraints limiting access for poor households.

Water for agriculture remains severely limiting in Machakos. Irrigation development is limited by water availability and infrastructure costs. Small-scale water harvesting and conservation irrigation using drip systems has expanded, but remains accessible only to farmers with capital and technical knowledge. Irrigation development could increase agricultural productivity but requires sustainable water management.
