Introducing eco-cistem™, an innovative product representing a breakthrough in toilet technology. This toilet cistern uses grey condensate water for flushing, making it a revolutionary solution for water conservation. The product has been installed in several commercial hotels and office facilities and is already delivering significant water savings. The new eco-cistem™ is specifically designed to work with air conditioning units that produce varying amounts of condensate water, which typically goes directly into the waste pipe. In an eco-cistem™ installation, this grey water is redirected to the toilet cistern and used to flush the toilet(s).
