About London
London is the capital city of the United Kingdom, known for its rich history, diverse culture, and significant influence on the arts, commerce, education, and politics.
Water Situation
Tap water in London is sourced primarily from the River Thames and River Lea, supplemented by reservoirs. It contains minerals such as calcium and magnesium, contributing to its relatively hard quality, though its safety has been well-maintained over time. The Drinking Water Inspectorate monitors water quality, with Thames Water being the principal distribution company responsible for supplying water to the city.
