''Accra Will Soon Be Flooded Without Rainfall If Government Doesn’t Deal With The Drainage System Now" – Building Consultant


Ing. Abdulai Mahama, a building and road consultant, has warned that if the necessary steps are not taken to avoid indiscriminate and irresponsible development on buffer zones around the Aburi Mountain and other adjacent municipalities to Accra, the nation's capital could be flooded in no time. 

"If you look at McCarthy Hill, Amasan, Pokuase, Kwabenya, Brekusu, Teiman, Abokobi, Oyarifa, and Ayi Mensah, these are the communities that are going to give Accra a hell of a problem in terms of flooding in the coming years," he told Alfred Ocansey on 3FM Sunrise Morning Show. 

According to him, Accra is a lowland location by nature, and when it rained in Aburi, Brekuso, Amasaman, Pokuase, and other areas, it took an average of 72 hours or more for the rushing water to reach Accra, however now the flood waters inundate Accra after only 30 minutes of rain. 

"I'm underlining that there will come a time when we won't get rainfall in Accra, but Accra would flood when adjacent areas rain." We can double the capacity of the Odaw drain, but we can't contain the volume of water coming from upstream. 

With the exception of around 10% plastic saturated water, the Odaw River is packed with about 80% silt." 

Mahama, a dedicated engineer, voiced concern about how the government and local governments routinely disregard the advise of technocrats and professionals. 

Ing. Abdulai Mahama and Komla Adom of TV3 produced a documentary titled "Time Ticking Bomb in the Weija Area" in 2020 to draw the attention of authorities to the looming threat, but regrettably nothing was done to avert the issue. Ing. 

In March of this year, Mahama warned that there would be an unprecedented amount of silt on the road, and that if it rained for 72 hours, the dual carriage road between Accra and Winneba would be covered in silt for days. 

"When we got rains this year, for the first time in Ghana's history, we had a total blockade of the Accra-bound length of the Mallam Kasoa highway for over 72 hours." "We're just lucky the rain hasn't gotten worse," remarked Ing. Mahama. 

He voiced worry about how the Ayi Mensah portion of the Aburi Mountain has been badly encroached upon by real estate developers and private individuals, despite the Inter-Ministerial Committee's caveat prohibiting people from developing on the supposed buffer zone. 

The valleys, according to the expert, are nature's own buffer, designed to hold and delay the flow of rainwater streaming down the mountain to the lowlands, preventing flooding. Real estate developers have destroyed the vegetation cover, while the rocks are carelessly blasted to feel the buffer zone. 

"If someone can buy land for over $250,000, you have no idea what kind of people are breaking the law and endangering our lives." 

Mr. Mahama also urged Assembly leaders not to undercut Assembly Engineers' efforts by pressuring them with unnecessary transfers if they insist on doing the right thing.
