Simple ways to save water

Thames Water Employee

If you’re looking out of the window, watching water run down the window pane, or you live near a river and always see it flowing along, you’d think that there’s a continuous supply of water for us to use in our day-to-day lives – and you’d be right!


It’s true that we’re fortunate enough to turn on the tap and have clean drinking water and flush our loos to have our waste taken away, but water is a precious resource and we can’t take it for granted.


We’ve all heard about climate change and population growth, but often the context is so removed that we can’t really grasp the scale of the issue.  Or can we? Well, to help put it into perspective, the population of London and the Thames Valley is consuming around 10,000 Olympic sized swimming pools a day and the population of this area is growing at around 100,000 people per year – that’s a full Wembley stadium with 10,000 people standing on the field!


As you can imagine, this is placing real pressure on our water resources. If we keep using water like we are, we’ll need an additional 250 million litres of water a day across London and the Thames Valley by 2050 – another 104 Olympic pools every day!


So, what can we do? Just think smart. Slight alterations in the daily lives of 3.5 million households can make a massive difference to the amount of water that we all use or save.


Let’s start with the kitchen…


Kitchen washing – ‘Tap’ into these tricks!

The average tap uses 6-8 litres of water per minute. Washing up under a running tap for 5 minutes can therefore require up to 40 litres of water – that’s the same as filling your sink up to the rim, twice. We wouldn’t buy 8 litres of bottled water and pour them straight down the drain would we, so why leave the tap running? The water from our taps is a better quality than bottled water. You can find about the quality of the water in your area here.  

The no-brainer big win is simply making sure the tap isn’t left flowing when not needed. But with the simple installation of a kitchen ‘swivel tap’, you can also save a litre every single minute. Doesn’t sound like much? Well, over a whole year this averages out at 2,900 litres saved in a household of four people.


To fit swivel taps:

  1. Unscrew the end of your current tap and remove any washers that are inside the spout.
  2. The swivel tap should fit directly onto the end of your tap.
  3. If it’s loose at all, a simple converter can be screwed on first, tightening the gap – easy.
  4. You’re ready to go.

You can also use less water by filling up a washing-up bowl instead of keeping the tap constantly running. Your plates and cutlery will still be cleaned, and you’d have helped save the planet in the process.

If you’re looking to install new dishwashers or washing machines, look for products with the new water label and/or the Waterwise recommended checkmark as these models can help you to save more water, energy and money.



Bathrooms – Adjustments that are a ‘showering’ success!  

We all like to keep clean with a shower or a bath. As we move into the hotter months, we tend to use showers more frequently to refresh ourselves. On average, showers use 8 to 10 litres of water a minute and a normal bath will easy use up 80 litres!


There are various ways you can keep enjoying your showers and stay clean without using so much water. A water-saving showerhead is a simple, easy-to-fit feature that could save you up to 22,000 litres of water a year! Don’t have a plumber nearby who you can call upon? Not a problem – here’s how you can do it…


To fit water-saving shower heads:

  1. Unscrew the existing showerhead.
  2. Save any washers that you’ve already fitted as you may be able to use them later.
  3. Secure your new water-saving showerhead onto the shower hose, tightening it by hand with a clockwise motion.
  4. Like the swivel taps, if any leaks occur, simply install the washer you previously saved, tightening the gap between the showerhead and the hose.
  5. You’re ready to go.

Prefer an approved plumber to fit your new showerhead? We’ve got you covered. Simply find an approved plumber near you.



Want to keep your current showerhead? With a ‘showersave’, the benefits are in the name! Fitting your showersave can be done without the use of tools.


To fit a showersave:

  1. Unscrew the shower hose from the point it meets the wall.
  2. Place the showersave over the hose end.
  3. Reattach the appliance to the wall.
  4. If the gap between the showersave and your shower system is more than 2cm, just remove one of the washers to stop any leaks and always remember to have at least one washer remaining.
  5. All done.

Why are showers so important? Given showers consume around 25% of an average household’s water usage, simple reductions in shower time can have a massive impact on overall usage. Having a shower for 4 minutes at 10 litres a minute uses just 40 litres of water – half that of having a bath!


Fancy a challenge? Try cutting down your shower time to 4 minutes using one of our shower timers. Fancy some entertainment to use as a timer? Check out this four-minute tunes playlist on Spotify – there’s something for everyone!


Toilets – A save-a-flush a day keeps wasted water at bay!

I think we’d all agree, loos are pretty important. But did you know that a older lever-handle single-flush loo uses at least 9 litres every flush?  Reducing flush volumes really saves a lot of water.  A ‘save-a-flush’ is a simple way to save a whole litre of water every flush – that’s 1,460 litres for a family of 4 every year.


To install this simple kit:

  1. Remove your toilet lid.
  2. Press the save-a-flush bag to release any trapped air in it.
  3. Quickly flush the toilet. As you do, attach the bag to the toilet system, furthest away from any moving parts with the bag inside the system.
  4. Place your lid back on.
  5. Wait 6 hours for the bag to expand and you’re good to go.
  6. Just check that the mechanism and overflow are not obstructed and there, you’re saving with every flush!


Did you know that 1 in 10 households have a leaky loo? A leaky-loo is when water is constantly running or rippling into the toilet bowl.  A leaky loo can double your water usage and waste 400 litres a day – that’s 5 whole bathtubs, doubling an average family’s total daily water use and their meter water bill.


If you can hear a flow of water when the toilet hasn’t been flushed or a constant trickle at the back of the toilet pan, there are a few simple ways to check if your loo is leaking:


  1. Wait until 30 minutes after the last flush then wipe the back of the pan dry with toilet tissue.
  2. Place a new, dry sheet of toilet tissue across the back of the pan. Leave it in place for up to three hours without using the toilet (it might be best to do this overnight).
  3. If the paper is wet or torn in the morning, you know you have a leaky loo.


If you do see your toilet leaking or continually refilling, the chances are that it’s not a design feature but a simple problem that needs a fix. Again, this will save you water, energy and money on your bills.



Sinks – Turn off the taps, turning on the savings!

Finally, don’t forget to turn off the tap when brushing your teeth.

A running tap can use up to 6 litres of water every minute. For a household of 4 across a whole year, this adds up to a huge 17,250 litres. Turning off your taps while you brush your teeth will not only keep your teeth white, but your water bills nice and tight. A bathroom tap insert is another easy to apply piece of kit that can save another litre of water every minute.


To fit bathroom tap inserts:

  1. Unscrew the nozzle of your tap where the water comes out, by twisting it anti-clockwise.
  2. Remove the seal and keep it safe for later.
  3. Remove the initial nozzle insert.
  4. Select the required adapter ring based on the tap size and material and insert the aerator into the adapter.
  5. Is the aerator falling out or doesn’t fit? Try placing the adapter the other way around.
  6. Insert it into the tap nozzle, with the white cap facing upwards and the mesh facing downwards.
  7. Pull the rubber seal back into the original position.
  8. Screw the tap nozzle back on clockwise.
