In every society much work goes into supplying our houses with fresh and potable water. In the past this meant hauling buckets of water from the nearest well or creek, a situation that unfortunately still persists in many parts of the world. The installation of PVC water supply networks over the past century has transformed the lives of millions of people across the world by providing clean and fresh piped water to their home every day to drink, cook or wash. PVC is also commonly used to build sewer systems to safely take used water away from our homes.
