Oniru share di same brackish water table with VI and Lekki. Most Oniru estate dey include tanker delivery for service charge, but quality dey vary. Ask estate management for water source documentation before you sign lease.
Oniru na beachfront Victoria Island territory, and im water situation na the coastal one: sink borehole here and the groundwater very often salty, because the Atlantic dey metres away and salt water dey intrude into the shallow aquifer. That single fact dey drive everything — raw borehole water okay for flushing and general washing but too salty for comfortable bathing, cooking or appliance without treatment, so house dey invest for filtration and reverse-osmosis system, or dey lean on delivered water.
The result na say water dey cost more here pass the mainland. Many premium home and serviced apartment dey run treated-water system or dey rely on tanker delivery of sweet water wey dem truck in, priced accordingly. Drinking water na invariably bottle or from RO filter. For anybody wey dey rent or buy for Oniru, water treatment no be optional extra but part of the cost of coastal living — budget for proper filtration setup or reliable tanker supply from the start, because borehole alone no go give you sweet water.
