The Lagos State Government has warned that building sewage treatment plants without the technical capacity to run and maintain them could erode the environmental and public health gains the facilities are meant to deliver, according to a report published on 10 September 2026 by Punch Newspapers. The warning accompanied a two-day capacity-building programme that trained more than 130 facility managers, engineers, environmental consultants and laboratory personnel who operate sewage plants across the state.
The training was organised by the Lagos State Wastewater Management Office (LSWMO) together with the Nigerian Institution of Environmental Engineers, with sessions covering wastewater treatment processes, plant operation and maintenance, laboratory analysis, effluent parameters, wastewater microbiology and process optimisation, according to Punch Newspapers.
KEY TAKEAWAYS
- More than 130 sewage plant managers, engineers, consultants and lab personnel were trained at a Lagos State programme held on the dates covered by the 10 September 2026 Punch report (Punch Newspapers).
- The Permanent Secretary in the Office of Drainage Services and Water Resources said construction alone does not guarantee adequate treatment, and called for regular monitoring of treatment processes and effluent quality (Punch Newspapers).
- The National Chairman of the Nigerian Institution of Environmental Engineers said plants across the country are underperforming because of gaps in technical capacity, operation and maintenance, and management (Punch Newspapers).
- The Commissioner for the Environment and Water Resources said the state must move beyond construction to regulation, professional capacity, water reuse and recycling, resource recovery and energy efficiency (Punch Newspapers).
- The LSWMO General Manager said the training was designed to close practical gaps in sewage plant management, including effluent compliance (Punch Newspapers).
WHAT HAPPENED
State signals a shift from construction to operation
The Permanent Secretary, Office of Drainage Services and Water Resources, Adegbite Mahamood, said the construction of treatment plants alone could not guarantee that wastewater would be adequately treated, according to Punch Newspapers. He said the facilities must be properly operated and maintained, and that their treatment processes and effluent quality must be monitored through regular testing.
The position was reinforced by the National Chairman of the Nigerian Institution of Environmental Engineers, Caius Ikem Umekesiobi, who was represented by the Immediate Past National Chairman, Nureni Adegboyega Ogunyemi, Punch Newspapers reported. "Some sewage treatment plants across the country were underperforming despite investments in their construction," Umekesiobi said, attributing the problem to gaps in technical capacity, operation and maintenance, and management.
The state Commissioner for the Environment and Water Resources, Tokunbo Wahab, represented by the Special Adviser to the Governor on Environment, Olakunle Rotimi-Akodu, said the challenge was becoming more pressing as wastewater from residential, commercial, institutional and industrial activities increased, Punch Newspapers reported. Wahab said properly treated wastewater could be safely managed and potentially reused, but warned that inadequately treated wastewater and indiscriminate discharge could contaminate water bodies and expose communities to public health risks.
What the workshop covered
The General Manager of the LSWMO, Adefemi Afolabi, said the training was designed to address practical gaps in the management of sewage treatment plants, Punch Newspapers reported. Participants were taken through wastewater treatment processes, plant operation and maintenance, laboratory analysis, effluent parameters, wastewater microbiology and process optimisation, with practical sessions included in the programme.
The workshop comes against the backdrop of the growing volume of wastewater generated by the state's expanding population and economic activity, making the ability to keep treatment infrastructure functional as important as the construction of the facilities themselves, according to Punch Newspapers.
An unrelated 2 March 2026 report from The Baltimore Banner described a separate development moratorium in parts of Anne Arundel County, Maryland, tied to sewage system capacity; that item is not the subject of this article.
SPECIFICATION READ
Lagos did not publish a plant-by-plant capacity figure in the workshop coverage; the only quantitative anchor in the reporting is the headcount of more than 130 trained professionals (Punch Newspapers). For a state-level programme aimed at municipal sewage serving a megacity of more than 20 million people, the indicative per-plant design range that buyers typically work to is 1 to 500 m³/day for decentralised packaged plants and 5,000 to 500,000 m³/day for central works, with municipal raw sewage BOD in the 200 to 400 mg/L range and TSS in the 200 to 350 mg/L range (general industry range, not from the sources). The treatment train a class of project like this requires is screening and grit removal, primary clarification, biological treatment (conventional activated sludge, MBBR, SBR or MBR where space is tight, with UASB in warm climates), tertiary polishing and disinfection; the Lagos workshop explicitly targets the operation and maintenance of the biological and tertiary stages, plus laboratory control of effluent parameters (Punch Newspapers). If your plant runs on raw municipal sewage in the 1,000 to 100,000 m³/day range with BOD of 200 to 400 mg/L and you are being asked to demonstrate effluent compliance, reuse and lower energy use, this is the procurement signal that regulators and engineering bodies are now prioritising operational competence, monitoring, reuse and resource recovery over new-build headlines. For background on the equipment categories involved, see our Industries We Serve hub, the Municipal treatment page, and the Integrated Sewage Treatment product hub; the comparative guides DAF vs Clarifier for Mining/Metals Wastewater in Zahl, ND: 2026 Factory Buyer's Guide and DAF vs Clarifier for Mining/Metals Wastewater in Caddo Gap, US (2026 Guide) are useful when a tertiary clarification step is being specified.
FAQ
What is the headline figure from the Lagos wastewater training?
A 10 September 2026 Punch Newspapers report says the Lagos State Wastewater Management Office trained more than 130 facility managers, engineers, environmental consultants and laboratory personnel at a two-day capacity-building programme (Punch Newspapers). No aggregate plant capacity or contract value was disclosed in the source.
What did the Lagos State Government say operators must do beyond building plants?
The Permanent Secretary in the Office of Drainage Services and Water Resources said facilities must be properly operated and maintained, with regular testing of treatment processes and effluent quality, according to Punch Newspapers. The Commissioner for the Environment and Water Resources added regulation, professional capacity, water reuse, resource recovery and energy efficiency (Punch Newspapers).
How does a buyer translate this into a plant specification?
The workshop scope, as reported by Punch Newspapers, points to a need for process optimisation, effluent parameter monitoring and microbiology. For a municipal plant in the 1,000 to 100,000 m³/day range, that maps to instrumentation on the biological stage, online or lab BOD/COD and TSS analysers, and a defined reuse or discharge compliance envelope (general industry range, not from the sources).
What is a realistic lead time for an integrated sewage package in this class?
Engineering, procurement and fabrication of a packaged municipal plant in the 1,000 to 50,000 m³/day range typically runs 6 to 12 months from purchase order to commissioning, with civil works on the critical path (general industry range, not from the sources). The Lagos programme shows that owners increasingly want O&M and training wrapped into the same procurement, so a buyer should request those deliverables in the tender.
