NIWA issues ‘best practice’ guidelines for dredging operations in Lagos State



*To punish non-compliant operators

The National Inland Waterways Authority(NIWA) on Thursday said it would punish dredging operators who fail to comply with the best practice guidelines it issued, arising from a stakeholders meeting in Lagos. 

The Lagos Area Manager, NIWA, Mr Muazu Sambo said that while the agency recognises its statutory responsibility as regulators of the dredging activities, it would ensure adequate enforcement to achieve compliance.

Sambo warned dredging operators along the Ajah-Badore stretch, who had yet complied with the regulations to do so, or face sanction, having been warned over six months ago.

He said operators within Sango-Tedo and other communities along the same axis should also brace up for NIWA compliance monitoring, as the agency would ensure adherence to guidelines for operations. 

The Lagos Area Manager clarified that all operators should deal with NIWA as pronounced at the Federal High Court, while stating that the matter was taken to the appeal court about two weeks ago.

Meanwhile, the guidelines for dredging operations signed by the Lagos Area Manager include;
