Ajah water situation mixed. Parts wey near Lekki-Epe Expressway get di same brackish problem with Lekki. But newer estate for di interior don find fresh water for 80-120m depth. Always test borehole water before you rely on am.
Ajah dey on the Lekki-Epe corridor between the lagoon and the Atlantic, and that coastal geology dey define im water. The water table high and borehole easy to sink, but closer to the water body dem often dey draw brackish or salty water wey okay for washing but unpleasant and corrosive over time — so treatment, or to drill deeper reach fresher layer, na genuine consideration across much of Ajah, Sangotedo and Awoyaya.
With public supply absent as practical source, nearly every home dey rely on borehole plus storage, and the many new build mean driller and treatment installer dey do brisk business here. Renter and newly-arrived resident dey lean heavily on tanker delivery until dem drill. Drinking water na bottle, sachet or filtered without exception. For fast-growing area where quality dey vary plot to plot, the smart move before you commit to house na to check wetin the borehole actually dey yield — sweet water or salty na real difference to daily life and running cost.
