Every case is different but the chart below can give you an idea on where the average household use the most of the water.

If your aim is to save water and save money on your water bill, have a look to the advice we are sharing below.

How to save water at home

1 - Install a water saving tap aerator

Old faucet models run on average of around 15 liters of water per minute while a standard aerator can reduce the water usage to as little as 6 liters per minute. Water saving tap aerators can reduce the water consumption even further and due to their low cost and easy installation are most definitely a water saving method to have in consideration.

We have installed a water saving tap aerator to a bathroom tap and the results speak by themselves

2 - Install a water flow reduction valve and reduce your shower water consumption

We have measured our shower head water flow and found out that we are using 11 liters a minute, not as many liters as an old model but still far away from a low flow shower head.

We have both tried to reduce our water consumption by installing a low flow shower head and also a water flow reduction valve. The low flow shower head that we bought claimed to reduce the water consumption up to 30% and it has been a disappointment because we have achieved a water saving of only 1%. Instead, the flow reduction valve has significantly reduced our water consumption.

3 - High efficiency toilets and dual flushing toilets

Older toilet models use up to 15 liters per flush while new toilet models use between 6 to 10 liters of water per flush where high efficiency toilets can go below even 5 liters of water. Dual flush toilets use 6 liters of water for solid waster and only 3 liters for liquid waste.

For anyone thinking about if the investment is worth the consider, we have made some calculations that may be of help. Note that this calculations are only to be used as orientation and we encourage each individual to make its own assessment.

4 - Toilet cistern water saving bags

For those who cannot afford to install a dual flush toilet, a toilet cistern water saving bad may be a more affordable option.
 
Still, we must warn everyone that we haven’t tested this water saving opportunity and our research shows that only around 50% of the people have given a positive review.
 
Until we have made our own tests, we consider this as a potential water saving opportunity that seems to work given some conditions like choosing the right water saving bag for a specific toilet and installing it correctly.

5 - Make sure that your house is water leaks free

Every so often we come across the news that someone we know has got a disproportionate water bill which it was due to a major water leak that went unnoticed for a few months.

But it also may be the case of small water leaks go unnoticed for very long periods, even years, which are draining our pockets at a steady rate so we do not notice, unless we check.

If you haven’t watch it yet, have a look to the video where we show how to read a water meter, because in the video we also show and inexpensive way to look for water leaks. In any case, on the table below we show how much money an water the smallest leak can cause.

Water leak

The simplest way to check for a water leak is to just check at the water meter:

1.- Stop using all water

2.- Record the number on the water meter

3.- Wait for a minimum of five hours (maybe during the night)

4.- Check again the water meter

6 - Use your appliances efficiently

Nowadays it is not that expensive to buy energy efficient appliances, like dishwashers or washing machines, that use much less water than older appliances. Still, it is proven that for getting the most from our energy efficient appliances we must use them correctly.

We have put our own home appliances to the test and compared the results between using an standard program or the ‘ Eco’ program. Out of our tests, we have noticed than we use the ‘Eco’ programs the cycles take much longer, well over three hours, but we are saving both in electricity and water.

Now, the question here is if it is worth to wait for over three hours for the dishwasher or the washing machine to finish one single cycle?

Well, it depends on the perspective. Even if you only use once your dishwasher and washing machine per week you will still be saving water, maybe only eight liters but if we multiply that value for thousands of households the number quickly increases to significant numbers.

Eco

For those of us who use the dishwasher and washing machines around 5 times per week, we are already speaking about saving 40 liters of water every week and around 1600 liters of water every year.

From the economic perspective, for those of us who pay 2 euro per cubic meter, 1600 liters only amount to save 2,5 euros per year. But from the environmental impact perspective, if we multiply 1600 liters by thousands of households, using the ‘Eco’ function really makes a big impact into reducing water usage.

In our house, we always use the ‘Eco’ programs and having to wait 3 hours does not bother us because we have just adjusted our daily routines a little bit. A little bit of awareness and a broader perspective really makes the difference.
