With temperatures, local populations and seawater intrusion on the rise in southern Florida, municipal water utilities are under pressure to maintain the flow of sufficient, sustainable freshwater supplies to communities. This is especially true for Sanibel-Captiva Islands, which have one source of potable water – the 5.99 million gallons treated and distributed daily by the Island Water’s Reverse Osmosis Treatment Plant. For over three decades, Island Water and DuPont Water Solutions have collaborated to meet freshwater demands and optimize process efficiency.
