Waterworks

The waterworks industry is among the largest markets for composite products, which are used in sewage treatment plants, pumping stations, water treatment plants, reservoirs, and flood control chambers. Composites are ideal in places with high humidity, chemically corrosive environments, or where hygienically safe products are required.
