If your borehole water in Lagos Island, Ikoyi, Lekki Phase 1, Chevron, or Victoria Island has started tasting salty or leaving a metallic edge behind, the problem isn't your tank or your pipes it's what's underneath your compound. These areas sit close enough to the Atlantic Ocean and the surrounding lagoons that saltwater finds its way into the aquifers homes and estates draw from.
Here's why that happens, why most filters on the market can't fix it, and what actually works.
Saltwater intrusion from the Atlantic Ocean and coastal lagoons infiltrates shallow and mid-depth underground aquifers. Properties along the Lekki-Epe expressway and the islands Lagos Island, Ikoyi, VI, Chevron are especially exposed because they sit on reclaimed or coastal land where the freshwater layer is thin and easily displaced by seawater, particularly during the dry season when groundwater levels drop.
Standard carbon filters cannot remove dissolved salts; only Reverse Osmosis (RO) membranes can desalinate water effectively. Carbon filters are built to trap chlorine, sediment, and odor-causing particles they were never designed to pull dissolved sodium and chloride ions out of water. Dissolved salt passes straight through a carbon or sediment cartridge unaffected, which is why many households in these areas have already tried a basic filter and are still stuck with the same taste.
iClear RO technology filters out over 99% of dissolved salts, sodium, and chloride ions to deliver sweet, pure drinking water. The RO membrane works at a molecular level, forcing water through a barrier fine enough to block dissolved salts while letting clean water pass through the same technology municipal desalination plants rely on, scaled down for home and office use.
The iClear Standard RO Purifier costs ₦450,000, offering complete salt and mineral balance for household drinking water. For larger households or properties with especially high salt content, the iClear Premier Purifier adds extra capacity and mineral management worth discussing after a TDS test confirms your exact salt levels.
RO systems discharge a reject brine stream, which can be safely routed to flushing tanks or external drainage. This is a normal part of how reverse osmosis works, and installation in Lagos Island, Ikoyi, and VI properties accounts for it as part of the setup it does not affect your main drinking water supply.
iClear conducts free on-site Total Dissolved Solids (TDS) tests in Lagos to determine exact salt levels prior to installation. A TDS reading takes minutes and tells you exactly how much dissolved salt is in your water, so you're not guessing before you invest.
