Lagos State directed borehole operators to obtain the required permits before drilling or extracting groundwater, warning that unauthorised facilities may be sealed and their operators prosecuted. The announcement, reported on 30 October 2026, was issued by the Lagos State Water Regulatory Commission, LASWARCO. No number of facilities, permits or prosecutions was reported Daily Post Nigeria.
Key takeaways
- LASWARCO said borehole drilling and groundwater extraction require relevant permits before operations begin Daily Post Nigeria.
- The commission said facilities operating without approval may be sealed and prosecution may be initiated against those responsible Daily Post Nigeria.
- The warning identified contamination, land subsidence and pressure on water resources as risks associated with unauthorised drilling and groundwater extraction Daily Post Nigeria.
- Residents and community leaders were asked to report illegal borehole drilling and unauthorised groundwater extraction Daily Post Nigeria.
Warning issued over unauthorised groundwater use
On 30 October 2026, LASWARCO directed borehole operators planning to drill or extract groundwater to obtain the relevant permits before commencing operations. The commission said unauthorised drilling and extraction could expose underground water sources to contamination, trigger land subsidence and endanger the state’s water resources Daily Post Nigeria.
LASWARCO Executive Secretary Oluwabukola Adeyemo said: “Drilling or abstracting groundwater without LASWARCO authorisation is illegal and punishable under the Law.” She also said the commission would seal facilities lacking the required approval and initiate prosecution against those responsible Daily Post Nigeria.
The enforcement warning came amid concerns about groundwater pollution in Lekki, where residents had previously been cautioned about possible consumption of contaminated water because of inadequate wastewater treatment Daily Post Nigeria.
Wastewater treatment linked to groundwater protection
In August 2025, Mahmood Adegbite, Permanent Secretary of Lagos State’s Office of Drainage Services and Water Resources, raised concerns that Lekki residents could be exposed to polluted water because of poor wastewater treatment practices. At a stakeholders’ meeting, he stressed the need for proper wastewater treatment to prevent further groundwater contamination and minimise the spread of waterborne diseases, according to the report Daily Post Nigeria.
Reporting on the state’s 2022 regulations, the source said they were introduced to prevent pollution and support sustainable management of underground water resources. At that time, LASWARCO Executive Secretary Funke Adepoju explained that the regulations covered groundwater abstraction, consumption, supply and distribution Daily Post Nigeria.
The current enforcement approach rests with LASWARCO under the Lagos State Environmental Management and Protection Law, 2017, which authorised the commission to oversee borehole drilling, groundwater extraction and water supply services. Residents and community leaders were asked to report suspected violations; the source did not report how complaints should be submitted, the number of facilities affected or a timetable for enforcement Daily Post Nigeria.
Specification read
The reported scale of the enforcement programme was not stated. No affected borehole count, groundwater-abstraction volume, wastewater flow, treatment capacity in cubic metres per day or population equivalent was reported, so those buyer-unit values cannot be calculated from the available information Daily Post Nigeria.
For a wastewater plant serving a borehole-dependent operation, the applicable treatment train normally progresses from screening and primary treatment to biological treatment, with the selected process matched to the discharge and reuse requirements, followed by tertiary treatment or disinfection where required. DAF or zero-liquid-discharge configurations may also be relevant where recovery or very tight discharge limits are required. This Lagos action bears directly on wastewater adequacy because inadequate treatment was identified as a route to groundwater contamination, although the report did not specify a process or capacity for any affected facility Daily Post Nigeria.
If your plant looks like a borehole-dependent industrial or commercial site with a discharge or reuse requirement in Lagos, this is what it means for you: treat wastewater adequately, document the treatment performance and verify groundwater-abstraction authorisation before relying on the borehole. When reviewing Wastewater Treatment Equipment, buyers should compare the proposed flow, organic-load limits, treated-water quality and reuse or discharge obligations against their permit conditions; the source supplies no numerical thresholds for that comparison.

FAQ
What permits are required before drilling or extracting groundwater in Lagos?
Individuals and organisations planning to drill boreholes or extract groundwater must obtain the relevant permits from LASWARCO before commencing operations. LASWARCO said drilling or abstracting groundwater without its authorisation is illegal and punishable under the law Daily Post Nigeria.
How much would treatment cost, and what would determine the price?
The source reported neither a project cost nor the number of facilities affected. A buyer would therefore need a measured wastewater flow, the relevant effluent or reuse limits, the required treatment process and site constraints before a supplier could provide a defensible cost. The report provides no numerical cost inputs or range Daily Post Nigeria.
Which wastewater treatment process should a Lagos buyer specify?
The report linked inadequate wastewater treatment with possible groundwater contamination but did not prescribe a treatment process. Process selection should follow screening, primary treatment, biological treatment and any required tertiary or disinfection stage, with DAF or zero-liquid-discharge options considered where the project conditions justify them. No flow, load or discharge values were reported Daily Post Nigeria.
What should be settled before selecting a treatment supplier?
Buyers should settle the wastewater flow, treatment objectives, applicable groundwater and discharge requirements, site conditions and permit documentation before comparing suppliers. For a borehole-dependent operation, LASWARCO authorisation is also necessary before drilling or extraction begins. The report did not give supplier qualifications, procurement lead times or comparative performance data Daily Post Nigeria.
