?In 2010 Procter and Gamble (P&G) established the Planta Milenio manufacturing facility in the basin. In order to minimize business risk and environmental impact the plant was designed to minimize the volume of water that would be abstracted from the basin for business operations. The total groundwater abstraction of the site had the potential to be in order of 480,000m3/year, however through the use of key measures such as extensive on site recycling, low water use fittings and rain water harvesting the total abstraction was reduced to 254 000m3/year. While the volume of water used by the plant remains largely unchanged, the volume of abstracted groundwater has been reduced by nearly 50%.
At a project cost of US$1,900,000, financed entirely by P&G, the 3000 person facility was fitted with flow plumbing fittings to reduce domestic water use, a reverse osmosis process to recycle waste streams from the water treatment plant, and rainwater harvesting measures, among others.
