Banana Island na di only Lagos neighborhood wey get genuinely independent water. Di estate management run im own water treatment plant. Water cost dey inside di big service charge (₦5-10M/year). For di ultra-wealthy family wey dey live here, water na one of di few Lagos problem wey money don actually solve.

Banana Island na man-made island wey dem reclaim from the lagoon, wey make im water story the most extreme for Lagos: the ground under am saturated with salt water, so raw borehole dey yield water wey too salty for normal use. The island ultra-premium development, dem build am knowing this, and the answer na engineering — central and private water-treatment plant, reverse-osmosis system and high-capacity storage wey dey turn brackish groundwater or delivered water into the sweet, treated supply wey resident dey expect.

That make Banana Island the highest-cost water environment for the city. Treatment system, their maintenance, and tanker delivery of sweet water all dey enter service charge and running cost wey dwarf mainland figure. Drinking water na bottle or RO-filtered as a matter of course. For resident here, water na simply part of the premium package — nobody dey rely on plain borehole, and the real question na the capacity and reliability of the treatment and storage wey dey serve the home, no be whether to drill one. Na the clearest example for Lagos of geography wey dey dictate how, and how expensively, water dey reach the tap.
