Lagos public water network serves about 1% of residents, LWC says
Lagos Water Corporation says its public water network serves about 1.03% of the state’s estimated 20 million residents, highlighting a wide gap between installed infrastructure and the number of households connected to public supply.
The corporation says 34,424 registered households are connected to its network.
Using an assumed average household size of six people, LWC estimates those connections represent about 206,444 residents.
The 1.03% figure is therefore an LWC estimate based on registered connections and assumed household size, not a direct census count.
Production far below installed capacity
LWC says its installed production capacity is about 210 million gallons per day.
Its average actual production in 2025 was 7.21 million gallons per day.
The corporation puts Lagos’s estimated daily water demand at about 540 million gallons.
Those figures show why installed capacity should not be confused with actual production or water delivered to households.
LWC says its 2025 average production amounted to only about 3% of installed capacity.
Rehabilitation projects underway
Lagos State and LWC have been working on rehabilitation intended to improve water production and reliability.
In February 2026, LWC announced an eight-month rehabilitation programme covering the Iju and Adiyan Water Treatment Plants, including works at Iju Headworks and Akute Intake Station.
The programme was scheduled to run from February through October 2026.
The state later said new pumps were being installed at Iju Headworks and Akute Water Intake Station as part of the rehabilitation.
But project schedules, installations and budget allocations do not establish that rehabilitation is complete, that plants are operating at planned capacity or that household service has normalised.
Capacity is not the same as delivery
The distinction is central to the accountability question.
A water plant can have installed capacity without producing at that level.
Water can be produced without all of it reaching customers through the distribution network.
And a project can be funded or under construction without producing measurable improvements in household supply.
The latest LWC figures therefore need to be read across three separate measures:
- installed capacity;
- actual production;
- and household connections and delivery.
What the network gap means for residents
Where reliable public supply is unavailable, households may depend on alternatives including boreholes, private water vendors and packaged water.
The latest verification does not establish how much households spend on those alternatives or quantify any resulting health or water-quality impact.
The public-service consequence is narrower but still significant: LWC’s own estimate says only about 1% of Lagos residents are represented within its registered household network.
What Lagos still needs to show
The central question is no longer whether Lagos has water projects.
It is whether those projects are producing measurable improvements in public supply.
The next accountability tests are:
- whether the Iju and Adiyan rehabilitation scheduled through October 2026 has been completed;
- Lagos’s current 2026 daily water production;
- how many additional households have been connected;
- how much produced water is successfully distributed to customers;
- and whether residents are seeing measurable improvement in service.
For now, the verified position is that Lagos Water Corporation estimates its network serves about 1.03% of residents, while actual production remains far below installed capacity and estimated demand and major rehabilitation works are intended to close the gap.
