At The Flood Company we take great pride knowing that over the last five years our flood defence products have been despatched and deployed to protect customers throughout the UK, but earlier this year we sent our Hydroshield flood barriers and gates to a customer in Accra, Ghana – one of our furthest exports to date.
Last week we received a very positive email from this customer who was grateful that The Flood Company’s barriers protected their community from a major flood where waters reached 1 metre high.
I am happy to report that the main gate barrier supplied with two centre posts saved us yesterday during a major flood in Accra and held back water of 1m height.

Initial figures suggest that between 140 and 190 mm of rain fell in 24 hours between 09 and 10 June in some areas of Accra, the capital of Ghana, on the Atlantic coast of West Africa. Most of the rain fell in a 3 to 6 hour period, according to local media. Although this time of year marks the start of the rainy season, this is still a significant amount. Accra would normally expect to see around 221 mm for the whole of June, according to WMO figures.
Accra – A City Blighted by Floods
The recent floods in Accra come almost exactly a year after the flood and fire disaster of 2015. Days of torrential rain in early June 2015 resulted in widespread flooding which left many seeking shelter.
After the 2015 disaster, President Mahama set out some plans for future flood prevention for Accra, in particular unblocking drainage systems and waterways. The National Disaster Management Organisation, the Hydrology Department of the Ministry of Water Resources, Works and Housing and the City Authorities were to coordinate the clearing and expansion of our waterways and the de-silting of drains. In a statement in June 2015, President Mahama said that “Drastic steps are necessary here if we are to permanently address this perennial problem. We will intensify efforts to expand and modernize our drainage system.”
Recently the Mayor of Accra, Alfred Oko Vanderpuije, announced that around 45 percent of the work on drains and river dredging had been done.
This time of year is the rainy season and Accra is predictably under water by the first week of June, as it did in 2014.
Poor drainage systems which are often blocked by trash and debris, as well as illegal building on flood plains are often cited as aggravating the city’s flood problems.
Korle Lagoon is regularly choked with silt and debris, forcing the Odaw River which flows into it to regularly burst its banks.
A project to upgrade the city’s drainage and flood mitigation was announced in 2013 under the project name of Accra Sanitary Sewer and Stormwater Drainage Alleviation Project. Several years on, it is still unclear how far along work on the project currently stands.
