  Q: How pure is London’s tap water?

  A: The design and operation of Thames Water’s drinking water treatment process are fundamental to ensure London’s water is pure. Constantly monitoring these processes helps Thames Water ensure the water leaving its treatment works meets quality standards. Each year the company carries out almost half a million tests of drinking water, complying with 99.98% of stringent national and European standards. This is amongst the highest in the UK.

  Q: Where does London’s tap water come from?

  A: 80% of our drinking water comes from storage reservoirs connected to the River Thames and the River Lee. The remaining 20% comes from boreholes connected to groundwater stores.

  Q: What processes does tap water go through before it reaches my home?

  A: Water goes though a rigorous set of processes before it reaches customers’ taps, and is monitored at all stages to ensure it is of the highest quality. For more information about Thames Water’s processes visit: www.thameswater.co.uk/waterquality

  Q: Isn’t tap water in London just recycled human waste?

  A: As a finite resource, all water will have been used in some capacity before, however, the actual proportion of water which might have been ingested before it enters supply is tiny. Of the 150 litres of water each person uses each day, only a very small proportion is for drinking (around 2 litres), with the rest used for other domestic purposes. 80% of London’s tap water comes from the River Thames and the River Lee, with the remaining 20% from groundwater. Although it is true that some of the flow in the rivers gets there from sewage treatment works, this water is treated to a very high standard before it blends with other water that reaches rivers through natural process. Water in rivers undergoes natural purification processes that continue in raw water storage reservoirs. All of the water abstracted from rivers goes through advanced water treatment processes and stringent tests to ensure that it is of the highest quality and is safe to drink.

  Q: Is it true that tap water contains hormones?

  A: No. Analysis of water abstracted from rivers, in storage reservoirs and in tap water has shown no detectable levels of hormones. Laboratory studies have shown that current water treatment processes would be very effective at removing hormones - if they were present.
