Due to climate change, we are increasingly confronted with longer periods of drought, which increase the demand for tap water but also lower groundwater levels. In order to continue to guarantee the water supply in these circumstances and also to offer a solution for homes that cannot be connected to the central water supply, we must dare to look at other water sources. That is why De Watergroep has started a pilot project with farmer Kristof De Smet in Harelbeke. Together with 3 technological partners, the water company produces drinking water from rainwater.
2 rainwater wells of 20,000 liters were installed at the farmer and a test container with 3 different water purification systems, from which the purified drinking water goes to the home. “To meet drinking water standards, we are investigating various water purification technologies from the companies Corsa, Valeco and BOSAQ. We will test each technology for 6 months. We use various sensors to determine how we can achieve the best water quality. We are currently testing BOSAQ’s technology. The water is filtered with activated carbon followed by ultrafiltration, and is treated with LED UV. With this technology we can supply up to 150 liters of water per hour,’ says Evelyn De Meyer, Decentralized Water Supply project manager at De Watergroep.
