Innovative technologies for the reuse of lightly loaded grey- and rainwater are becoming increasingly important worldwide. Today, water reuse technologies contribute to improving the security of water supply cost-efficiently and serve as an attractive option to countries that have limited water resources or lack sufficient infrastructure. Even in water-rich areas, long-term savings and the ecotechnological optimisation can provide a significant incentive for using such technology.
Successfully marketing water reuse systems lies not only in attractiveness and profitability of the product, but also in the access to the international markets they create. The product testing and certification is a key element of international marketing and allows the manufacturers to have credible and independent proof of quality, performance and durability of their product.
