Maruba Dam is the source of water for Machakos and is located across River Maruba in Machakos District.  The dam was constructed in the late 1950’s to supply water to Machakos Municipality covering an area of 10 km². 

In June 2010, the Authority finalized rehabilitation of Maruba dam by raising the height of the embankment wall and spillway by 6 m. This increased the dam’s storage capacity from 0.60 Million m3 to 2.45 Million m3.  Increase in storage volume has ensured increase in water supply to Machakos Town and its environs from 2,050 m3/day to 8,700m3/day.

The Dam was commissioned in the year 2010 and is currently main water supply source for the Machakos town. It is estimated that the project serves more than 200,000 people in Machakos County.  Machakos Peoples Park is majorly successful due to the beautiful scenery provided by Maruba Dam. 

The dam is located in Machakos County. It has a water storage capacity of 2.45 million metres cubic. It serves over 200,000 residents in the region.
