NADMO launches desilting operation to combat flooding in Kumasi

As a result of the rainy season, Kumasi and parts of Accra are already facing the severe effects of flooding. Blocked drains, heavy silt buildup, and illegal structures on waterways have significantly worsened the situation, flooding homes and streets. What was once a effective water management system is now blocked, leading to floods whenever there is heavy rainfall.

On Saturday, May 17, the Aboabo storm drain, and other areas experienced overflow, causing water to surge into nearby homes. Resident link the constant flooding to years of lack of maintenance and inadequate drainage.

Aisha Usman, a resident of the Airport Roundabout area said “The main issue we face is silted drains. If the authorities take action to desilt and clear the sediment around the drainage system, it will significantly reduce flooding in the area.”  Many of Kumasi’s drainage systems, initially designed to depths exceeding eight feet, have been reduced to less than four feet because of the heavy sand deposits—significantly impeding water flow.

In response, the Ashanti Regional office of the National Disaster Management Organization (NADMO) has introduced emergency operations to deal with the flooding crisis. To deal with the problem, NADMO is implementing a comprehensive desilting campaign targeting 17 major drains across Kumasi.

The Ashanti Regional NADMO Director, Mohammed Nasir Ibrahim explained that “We are going to dredge and remove all the filth and sand so that the water can flow freely. Some of the culverts are too narrow and, with additional silt, the space available for water passage has reduced drastically. That’s what is causing the flooding.” But the actions go beyond temporary fixes.

NADMO is advocating for long-term infrastructural solutions. Mohammed Nasir Ibrahim added that “We have submitted a proposal to the Hydrological Service and relevant authorities, recommending the expansion of existing culverts and the implementation of concrete lining. Additionally, we propose the use of concrete reinforcement along a 200-meter stretch of the drainage banks to enhance durability and flood resilience.”

Mr. Ibrahim also appealed for support from the private sector: “We call on organizations and well-to-do individuals to support us in executing this exercise successfully, to reduce the impact of flooding in the region.”
