✅ Recommended water strategy
TEST FIRST: Get a professional water test before deciding. If the borehole is fresh, basic filtration works. If brackish, fall back to tanker delivery (₦30,000-₦40,000 per 10,000L in Ajah).

Ajah's water situation is a mixed bag. Parts closer to the Lekki-Epe Expressway have the same brackish groundwater issues as Lekki Phase 1. But newer estates in the interior have found fresher water at 80-120m depth. The rapid, unregulated development in Ajah means water quality varies dramatically from one estate to the next — always test borehole water before relying on it. Tanker delivery is cheaper than Lekki (₦30,000-₦40,000 per 10,000L) because of the proximity to mainland tanker depots.
