By every measure, Lagos is one of Africa’s fastest-growing megacities. It generates thousands of tonnes of municipal waste daily, operates an extensive waste management system, and has repeatedly launched sanitation campaigns.
Yet, a drive through the Lagos-Abeokuta Expressway, Oshodi, Ketu, Ikorodu Road, Awolowo Way in Ikeja, Lagos Mainland or several inner-city roads presents a troubling contradiction: heaps of refuse on road medians, kerbs, road shoulders and market corridors continue to define the urban landscape, reports Daily Independent.
The persistence of indiscriminate waste dumping is no longer merely an environmental concern.
It has become a transportation, public health and economic challenge, undermining the state’s investments in road infrastructure and traffic management.
For motorists, roadside refuse narrows carriageways, obstructs visibility and forces pedestrians onto traffic lanes. During rainfall, blocked drainage channels contribute to flooding, slowing traffic and accelerating road deterioration. The result is longer commuting hours, increased vehicle operating costs and greater risks of crashes.
The Lagos State government has consistently maintained that indiscriminate dumping remains illegal and unnecessary.
Governor Babajide Sanwo-Olu recently reintroduced the monthly environmental sanitation exercise, urging residents to dispose of waste only through their designated Private Sector Participation (PSP) operators rather than dumping refuse on roadsides or in drainage channels.
Beyond the monthly sanitation exercise, Lagos also enforces environmental cleanup activities in markets and business districts while the Lagos Waste Management Authority (LAWMA) continues public enlightenment campaigns encouraging waste sorting, recycling and responsible disposal.
Despite these efforts, the refuse heaps remain.
The obvious question is why. The answer lies in a complex combination of operational deficiencies, rapid urbanisation, behavioural attitudes and infrastructure constraints.
The foundation of Lagos’ waste management system is the Private Sector Participation (PSP) programme introduced in the late 1990s. Under the arrangement, licensed private operators collect household waste while LAWMA regulates, monitors and manages disposal infrastructure.
The model was designed to leverage private-sector efficiency while reducing the financial burden on government.
However, the system has increasingly struggled to keep pace with Lagos’ explosive population growth.
Several residents frequently complain of irregular waste collection, delayed evacuation schedules and insufficient waste trucks serving densely populated communities.
When refuse remains uncollected for days or weeks, many households resort to the easiest option of disposing waste under the cover of darkness on road medians, junctions and drainage channels.
LAWMA itself acknowledges operational challenges.
Managing Director Dr. Muyiwa Gbadegesin recently explained that heavy rainfall, difficult landfill conditions and operational pressures have slowed truck movement and increased turnaround times for PSP operators, affecting waste evacuation across parts of the state.
Infrastructure also remains a significant obstacle.
According to LAWMA’s own assessment of the PSP system, poor road networks, inadequate numbers of waste compactors, difficulties in collecting waste service charges from residents and negative public attitudes towards proper waste handling continue to undermine service delivery.
Where operators struggle financially because residents fail to pay waste collection bills, equipment maintenance and fleet expansion become difficult, creating a vicious cycle of poor service delivery and declining public confidence.
Government has not ignored these shortcomings.
Earlier this year, LAWMA withdrew the licences of five underperforming PSP operators and redistributed collection routes to better-performing contractors, insisting that operators unable to meet service standards would no longer be tolerated.
The decision reflected official recognition that regulatory enforcement must extend beyond residents to the operators themselves.
Official statistics equally reveal the scale of the challenge.
LAWMA reported that over 418,500 tonnes of waste were evacuated across Lagos in May 2026 alone, which is about 13,200 tonnes every day through its network of more than 400 licensed PSP operators.
Those figures demonstrate enormous operational capacity.
Yet the continued presence of refuse on major roads suggests that evacuation volumes alone cannot measure success. What matters to residents is whether waste disappears from their streets before it becomes an environmental nuisance.
Behavioural factors also remain significant.
Many commercial establishments and market operators continue to dump refuse outside approved collection periods. Some transport operators and traders use road medians as temporary dumpsites, while illegal cart pushers often deposit collected waste at convenient roadside locations instead of authorised disposal facilities.
These practices overwhelm LAWMA’s routine evacuation schedules and quickly recreate refuse heaps even after cleanup exercises.
The consequences extend well beyond aesthetics.
Roadside waste reduces effective lane widths, obstructs drainage channels and creates breeding grounds for rodents, mosquitoes and disease-causing organisms. LAWMA has itself warned that poorly managed waste disposal contributes to environmental degradation and public health risks, particularly around uncontrolled disposal sites.
For traffic managers, refuse heaps create additional operational burdens.
Vehicles slow near dumpsites, pedestrians spill onto carriageways while avoiding garbage, and flooding triggered by blocked drains frequently compounds congestion. Emergency responders also face delayed access during heavy traffic caused by flooded or obstructed roads.
The economic implications are equally substantial.
Businesses operating along refuse lined corridors suffer declining patronage, property values are affected, while government spends billions of naira annually on road maintenance, drainage clearance and emergency waste evacuation that could otherwise be invested in new infrastructure.
Experts increasingly argue that enforcement alone cannot solve the problem.
A more sustainable solution requires consistent household collection services, stronger regulation of PSP operators, expansion of waste transfer stations, increased recycling incentives, wider deployment of waste sorting programmes and tougher prosecution of illegal dumpers.
Technology can also play a larger role through GPS tracking of collection vehicles, digital monitoring of service performance and mobile platforms allowing residents to report missed collections and illegal dumping in real time.
Ultimately, Lagos’ waste challenge is not simply about refuse. It is about governance, infrastructure, public responsibility and urban planning.
As Africa’s commercial capital aspires to become a cleaner, smarter and globally competitive megacity, roads should serve transportation and not waste disposal.
Until residents fulfil their civic responsibilities, PSP operators consistently deliver reliable services and regulatory authorities sustain strict monitoring and enforcement, refuse heaps will continue to undermine the image and functionality of Nigeria’s economic capital.
The battle against roadside dumping cannot be won by government alone. It requires an effective partnership between authorities, waste operators, businesses and every resident determined to keep Lagos moving and clean.
