A Nigerian man has been sentenced to 18 months in prison for storing human waste at a residential property in Lagos, in a case that saw unprecedented cooperation between British environmental health officers and local authorities. The sentencing, handed down at the Lagos High Court on Tuesday, marks the first conviction under Nigeria’s 2019 Environmental Health Act for the wilful accumulation of faecal matter.
The defendant, identified as Chibueze Okafor, 42, was found guilty of maintaining a basement storage facility containing over 200 plastic barrels filled with untreated human waste. Investigators described the site as a public health hazard, with evidence of leakage into nearby drainage systems.
Two British environmental health specialists from the UK Health Security Agency assisted Nigerian counterparts during a three-month investigation that began in December 2024. The team provided forensic analysis of the waste and expert testimony on the risks of pathogen transmission, including cholera and typhoid.
Prosecutors said Okafor collected the waste from residential septic tanks under the pretence of operating a legitimate sanitation service. Instead, he stored the material in an unventilated basement adjacent to a primary school. More than 300 children were found to have attended classes within 50 metres of the site.
Magistrate Adebayo Adekunle described the offence as “a calculated disregard for public health and human dignity”. He added that the presence of British experts underscored the severity of the crime and the need for international cooperation in environmental enforcement.
The case has drawn attention to the growing problem of informal waste disposal in Nigerian cities. Lagos State alone produces an estimated 10,000 tonnes of solid waste daily, with less than 40% collected by licensed operators. The remainder is often dumped illegally or stored in unsafe conditions.
Nigeria’s Environmental Health Act was enacted in 2019 but has rarely been used to prosecute individuals for waste-related offences. Legal experts say the case could set a precedent for more aggressive enforcement.
“The involvement of British investigators signals a new level of scrutiny,” said Dr. Femi Ogunlesi, a Lagos-based public health lawyer. “It shows that environmental crimes will not be treated as minor nuisances. This is a serious regulatory matter with transnational implications.”
The British High Commission in Abuja confirmed the assistance was provided under a bilateral technical cooperation agreement signed in 2022. A spokesman said the UK was committed to helping Nigeria strengthen its environmental health capacity.
Human waste storage poses acute risks in tropical climates. Decomposing faecal matter releases methane and hydrogen sulphide, both toxic and flammable. The explosion risk at the Lagos site was described by investigators as “considerable” during initial assessments.
Okafor’s defence counsel argued that he lacked the resources to properly dispose of the waste and was attempting to find a licensed treatment facility. The court dismissed the claim, noting that he had been storing the material for at least 14 months without taking any action.
Community leaders near the school have welcomed the sentence but called for tougher penalties. “This man endangered our children,” said local council chairman Ibrahim Musa. “The law should reflect that. 18 months is not enough.”
Nigeria’s Ministry of Environment said it would launch a review of waste management licensing procedures following the case. Officials also urged residents to report any similar activities via a new hotline established in partnership with the UK.
The case highlights the broader challenge of urban sanitation infrastructure in West Africa. With rapid population growth, cities like Lagos struggle to provide basic waste services. International agencies have warned that unregulated waste handling could fuel disease outbreaks and environmental degradation.
For now, the conviction offers a rare instance of accountability. Whether it triggers systemic change remains to be seen.
