Half a liter of tap water costs €0.0006-0.001 in Estonia, depending on the municipality. A half-liter bottle of water costs around €1 in shops, or over a thousand times more. In volume, tap water therefore costs around 1000-2000 times less than bottled water. There are a few exceptions, but in Estonia the quality of tap water is generally very good. For example, a survey in Tallinn in 2021 showed that almost 90% of the population drank tap water. In addition to its high price, bottled water has a much larger ecological footprint than tap water. Bottled water can be transported hundreds or thousands of kilometers to the store, and non-renewable natural resources and energy are used to produce it. Long shelf-life and standing at room temperature can lead to microbial growth in bottled water.

According to various calculations, a modern and economical dishwasher uses 2-5 times less water to clean the same amount of dishes than it would by hand. Washing dishes by hand can also save water if you don't let it run all the time. When using a dishwasher, to save water and energy, it would be wise to load it up with a full load of dirty dishes rather than just a few plates. Contrary to common practice, it is not a good idea to rinse the dishes before putting them in the dishwasher. Firstly, rinsing wastes water, and secondly, the dishwasher's sensor will then misinterpret the dishes as almost clean and the cleaning may be incomplete.

In the 2023 dry season (May-June), the consumption of water in Viimsi Municipality increased by 37% compared to the usual period. The only logical explanation is that there was a massive irrigation of lawns, flowers and fruit trees. With such a high use, there was a risk that there would not be enough water for everyone and residents were asked to stop watering their gardens with drinking water. In Viimsi municipality, the planning of new residential areas was significantly curtailed, as there may not be enough drinking water for everyone. It is wise to collect rainwater in special containers for watering gardens.

Around 40 litres of Europeans' daily drinking water is used for bathing or showering and flushing the toilet. This is followed by laundry (20 litres), handwashing (15 litres), cleaning (10 litres), dishwashing (7 litres) and cooking (6 litres). Using good quality drinking water in the toilet is a waste of water. If possible, buy a dual-flush and/or a toilet bowl with a smaller flush tank, as this will save a lot of clean drinking water.

On average, in a bath we use 2-3 times more water than a shower. To save water, showering should be preferred whenever possible. However, it is also a good idea to limit your water use when showering - for example, by turning off the shower while you wash. For example, if you let the water flow from the shower for 20 minutes in a row, the water saving in front of the bath disappears. It's also a good idea not to fill the bath to the brim when taking a bath.

According to 2021 data, the highest price per m3 of water service per inhabitant was in Saaremaa (5.13 EUR), followed by Ida-Virumaa (4.18 EUR), Pärnumaa (4.13 EUR) and Järvamaa (3.94 EUR). The cheapest water service for residents was in Valga County - EUR 3.12. Saarlanders, on the other hand, use the least amount of water on average (around 50 litres per day, or about half the Estonian average). Perhaps the higher price has made the inhabitants of the Saarland save more water?

In 2021, people in Viimsi used an average of 152 litres of water per day (Estonian average was 89 litres). In municipalities bordering Tallinn, for example, residents of Jõelähtme municipality and Rae municipality used an average of 125 and 95 litres respectively.

While in Estonian cities most drinking water comes from deep groundwater through boreholes, 90% of drinking water in Tallinn is collected from surface water. For this purpose, water from the catchment areas of the Soodla, Jägala and Pirita rivers is diverted to Lake Ülemiste in a total area of 1,800 km2 and purified before being discharged into the city's drinking water pipelines. The quality of the drinking water is satisfying for the citizens of Tallinn, with almost 90% of end-users drinking tap water in 2021 (down from 48% in 2011). Only the residents of Nõmme, Laagri, Merivälja, Pirita and Tiskre get their drinking water from regional groundwater.

Power plants are the largest users of water in the country through the use of cooling water. In 2022, power plants and oil plants together will use about 880 million m3 of water, or about 2500 litres per capita per day in Estonia. Cooling water is usually taken from the river and after passing through the turbine room of the power plant, is released back into the river and the chemical properties of the water do not change in the meantime. The only difference is that the temperature of the water released back into the river has risen by about 7 degrees, reaching over 30 degrees in summer. For example, cooling water discharged back into the Narva reservoir from the large oil shale power plants in the Narva region can raise the temperature of the reservoir and the Narva River to 28 degrees Celsius in hot summers, affecting the ecosystems there. The share of cooling water in the annual average runoff of the Narva River averaged 13% between 1990 and 2011.

To keep your car in good condition, it is recommended to wash it at least once a month. As washing the car leaks detergent, chemicals from the car's dirt, asphalt residues and petroleum products, the car should be washed at a car wash, where the wash residues are directed to a treatment system. Washing your car close to a water body is prohibited. Washing your car at home is not explicitly forbidden, but it would leach chemicals into the soil and is not environmentally friendly.

Microplastics are already polluting almost the entire ecosystem of our planet, including Estonia.
Microplastics have been found in soil, in lakes, in the ocean, in fish; also in our food and bottled water and even in the human body.
Every year, more than 300 million tonnes of plastic are produced worldwide, half of which is single-use and at least 8 million tonnes of plastic end up in the oceans every year.
Studies show that by 2050 there is likely to be more plastic in the seas and oceans than fish.
Microplastics, or plastic particles between 0.1 and 5000 μm in size, are everywhere today. The tiny particles of plastic float around in bodies of water, entering the marine animal food chain, our food supply and so also humans.
In one year, humans consume about 250 grams of plastic. If we think that one plastic bottle cap weighs 2 grams, we eat nearly 125 bottle caps a year!!! What is this amount of plastic doing to our health?
