Where Does Our Wastewater Go?In city homes, wastewater runs into a sewerage system. Our toilets, baths, showers, washing machines and sinks are all connected to the sewerage system. This system can be made up of small and large pipes, a pumping station and treatment plants. When the wastewater is treated, harmful chemicals and bacteria are removed, turning it into a purified liquid called effluent and solid waste called biosolids. There are regulations in the United States to make sure that effluent is clean enough to be released into the environment. In other countries though, this is sometimes not the case. In countries that don’t have proper sewerage systems, raw sewage is often pumped straight into rivers and the sea, causing many environmental and health problems
