where does tap water come from in london
Water supply and sanitation in London London has well developed water supply infrastructure. Most drinking water consumed in London comes from the River Thames and the River Lee. Approximately 70% of all water supplied to London is taken from the Thames upstream of Teddington Weir.[2]
Fresh water Fresh water habitats are divided into lentic systems, which are the stillwaters including ponds, lakes, swamps and mires; lotic, or running-water systems; and groundwater which flows in rocks and aquifers. There is, in addition, a zone which bridges between groundwater and lotic systems, which is the hyporheic zone, which underlies many larger rivers and can contain substantially more water than is seen in the open channel. It may also be in direct contact with the underlying underground water. The majority of fresh water on Earth is in ice caps.
