Under the Water Act of 2016 the mandate of the Coast Water Works Development Agency is to develop and maintain sustainable water and sanitation infrastructure within the Coast region. The main transmission pipelines, including Mzima, Baricho, Marere and Tiwi – Likoni lines are maintained by the CWWDA. Pipeline patrols are critical in ensuring that leaks and bursts are detected and attended to on time to avoid wastage of the resources. The Mzima pipeline which was developed from 1953 is prone to leaks and bursts. Over the last decade the Agency has developed major key infrastructure including the recently completed project of drilling and equipping of 3 additional boreholes in Baricho, development of the 56Km 500mm diameter Malindi – Kilifi water pipeline, the development of the 37Km 400mm diameter Malindi – Gongoni water pipeline, and construction of a 5,000m3 storage reservoir at Kilifi.
