Ebook: How tap water is treated in the UK
Before water can become drinking water, it must first be collected, filtered, chemically treated and disinfected. According to the UK government, the country has more than 258,000 miles (416,000 km) of water mains and over 244,000 (393,000 km) of sewers, which combined is enough to stretch to the moon back.
Meanwhile, a government report in 2012 revealed that more than 11 billion litres of wastewater are collected every day in UK sewers.
Wastewater (or sewage) is generally made up of used water from baths, sinks, washing machines and toilets, wastewater from industry and rainwater run-off from roads and other surfaced areas.
However, diverse sources of wastewater can carry many water-borne contaminants, which all need to be dealt with by the water treatment plant.
