The LED water provides accessible expertise and services with regard to water treatment and reuse. Companies (with a focus on SMEs) and organizations receive free advice and guidance in everything that has to do with the choice of water sources, technologies and/or improvement of production, water treatment or water management. The LED operation can consist of an intake interview with site visit, advice, referral to the right person or organization (if necessary), a water scan (in which an inventory is made of water consumers, water sources and wastewater flows and a calculation of the available volume of rainwater) and /or an exploratory test.
