Tile production can be very water intensive. A large amount of water can be used in the preparation of glazes. And much more is used to rinse and stage the tiles. The waste water can be toxic. In any case, the solids have to be removed to prevent silt from being released into the sewage system. Tile manufacturer Interstyle – sponsor of Aboutglasstile – separates solids from the glaze waste water. The filtered water is loaded into a settling drum for reuse. Water lost during the production and filtration processes can be made up passively. Captured rain water is added to the filtered glaze water. Both sources are piped into a 60,000 cu ft water tank. Some chemicals are added to stabilize the water. The ROI on the entire capital outlay is less than two years. Water recovery makes sense.
