Banana Island is the only Lagos neighborhood with genuinely independent water infrastructure. The island's estate management operates its own water treatment plant, processing brackish groundwater through industrial-grade reverse osmosis before distributing to residences. Water costs are bundled into the substantial service charges (₦5-10M/year) that Banana Island residents pay. For the ultra-wealthy families living here, water is one of the few Lagos problems that money has actually solved.
Banana Island is a man-made island reclaimed from the lagoon, which makes its water story the most extreme in Lagos: the ground beneath is saturated with salt water, so a raw borehole yields water far too saline for normal use. The island's ultra-premium developments were built knowing this, and the answer is engineering — central and private water-treatment plants, reverse-osmosis systems and high-capacity storage that turn brackish groundwater or delivered water into the sweet, treated supply residents expect.
That makes Banana Island the highest-cost water environment in the city. Treatment systems, their maintenance, and tanker deliveries of sweet water all feed into service charges and running costs that dwarf mainland figures. Drinking water is bottled or RO-filtered as a matter of course. For a resident here, water is simply part of the premium package — nobody relies on a plain borehole, and the real questions are the capacity and reliability of the treatment and storage serving the home, not whether to drill one. It is the clearest example in Lagos of geography dictating how, and how expensively, water reaches the tap.
