Your water starts its journey in the stunning area of Upper Teesdale, home to some of England's rarest upland plants and the impressive waterfalls of High and Low Force.
Rainfall collected in open-air reservoirs in Upper Teesdale, and water from the River Tees is moved to two of our water treatment works by a series of pipes and pumps.
The two water treatment works, Lartington, based near Barnard Castle, and Broken Scar, in Darlington, process the water through several stages to make sure every drop is treated to the highest standard.
From there, the water is moved through a network of water mains to a number of service reservoirs (treated water storage tanks) across Teesside. The treated water is stored there until we need to push it along our huge network of pipes to your home so that when you turn on the tap, you've always got clean, clear and great tasting water.
We're pleased you asked! Technically, yes, water falls from the sky. However, we strongly advise against drinking it straight from a puddle!
Not only do we hold ourselves to high standards, but so does the law. We treat and test our water (a lot!) to make sure it meets all requirements and regulations.
We spend a huge amount of effort, energy and time turning rainfall into the wonderful wet stuff that comes out of your tap. We’re proud to supply our customers with some of the best quality tap water in the UK, not to mention cleanest in the world.
We treat and supply 675 million litres of water every single day.
To keep up with demand, sometimes we need to move water around our huge network of pipes or use different sources of water for a short amount of time. All our water is treated to the same high standard, however, when we make changes like this, you may notice a difference in taste or smell.
We all get used to the taste and smell of our water, so any small change can be noticed instantly, this is completely normal. The change can often be improved by chilling your water in the fridge for an hour or so or popping a slice of lemon in your glass if you can’t wait that long.
If you notice a major change in the taste or smell of your water,
check out some information about taste and smell for advice and help.
Recently, we’ve seen an increase in the amount of water that everyone’s using. To help us, and to make sure everyone has the water they need, please use your water wisely. You can find out more about saving water because water’s worth saving.
