The Lagos State government has identified a combination of technical drainage issues, illegal construction on floodplains and indiscriminate refuse dumping as the main causes of the flash floods that affected parts of the city on Tuesday.
Environment and Water Resources Commissioner Tokunbo Wahab disclosed on Wednesday, September 24, 2025, in a statement shared via his official X account, expressing sympathy for residents whose homes and businesses were disrupted.
He noted that Lagos, as a coastal city, remains naturally vulnerable to flooding when heavy rainfall coincides with tidal lock.
Wahab explained that, despite continuous investment in drainage infrastructure, regular desilting, and enforcement of environmental laws, persistent infractions by residents have worsened flooding incidents.
He highlighted Kusenla as an example where a technical issue exists, with the downstream level sitting about 1.2 metres higher than the base of the drainage.
The state has already awarded a project there that includes the construction of a pumping station to address the challenge.
By contrast, he said flooding around the House on the Rock church area was largely due to illegal construction on floodplains and the dumping of refuse in drains.
Videos circulating online showed clear breaches of environmental regulations, including unauthorised land reclamation without environmental impact assessments or drainage clearance.
The commissioner added that the government would promptly remove obstructive structures and illegal reclamations, stressing that the flood was a flash incident that had already receded.
He urged residents to support flood management efforts by refraining from building on floodplains and properly disposing of waste.
Wahab assured the public that the government remains committed to improving flood control systems across Lagos and will continue to enforce environmental laws to protect lives and property.
