Money is not an easy topic for conversation, especially if it is related to deficient financial resources which allow meeting basic life needs. But the fact that anyone’s life standard is not high can be a reason of pride when because of that our water supplies are used reasonably. However, a problem of saving water should not be a taboo topic. Minimizing daily water use will be beneficial not only for our wallet, but also for our world.

XXI century is a time of fast technological development. As the potential purchasers we are bombarded with a huge number of adverts which reach us through the press, the television and the Internet. The aim of advertisement is to present a commodity in the most attractive way to encourage us to become its owners. In the sea of bargains, rebates and discounts it is worth watching this technological news, which, according to assertions of products’ promoters, not only improves our lives comfort, but they also help us to save used water which we pay for.

Buying a dishwasher and a water softener proves to be a good solution. While traditional washing 12 sets of tableware with running water we consume 94 gallons of water and 2, 1 kWh of electric energy to heat it. According to scientists from Bonn, while doing the same job with the dishwasher, only 12 gallons of water and 1, 05 kWh of electric energy is consumed. In one year we can save in this way 154, 24 zł for water and 500 zł for electric energy. While the softener installed before the dishwasher will allow the reduction of high water hardness and by this washing means and it will prevent accumulation of stone and extend the service life of the device.

The holders of the dishwashers should also remember not to set up devices on the preliminary rinsing. The research carried out by the American magazine “Consumer Reports” proves that this activity does not improve the quality of dish washing and moreover 24 gallons of water in the year is consumed to do it. Investing in a shower stall in place of a bath tub is another solution which implements the policy of rational use of water resources. While taking 10-minutes shower we use from 30 to 40 gallons of water which is ¼ of water used during taking a bath. Our account balance wanes when we ignore some defects. A leaking faucet or flush mean a redundant loss of money. A distinctive sound of leaking tap with an average frequency of one drop per second is not only annoying for householders, but it is also a burden for a household budget because it leads to a fruitless waste of 5 thousand gallons of water in a year.

The faucet aerator has recently become very popular in the consumer market. It is found at the tips of the faucet or showerheads and its role is to optically increase a water stream by its aeration and flow restriction. Widely available, easy to install, affordable faucet aerators reduce about 50-60% of annual water exploitation and they reduce the costs of maintaining a household. The conscious management of water resources strategies with the use of modern technology are gradually implemented in Poland. This is the effect of the August meeting in Stockholm which was attended by 2,5 thousand experts from 130 countries who specialize in the water management. Increasing awareness of the scale of the problem of access to drinking water in the world, both in African (the Republic of Mozambique, the Republic of Sudan) and European (Russia, Balkans) countries and encouraging to constant water saving are profitable. Therefore, let us proudly talk: “My water do not overflow…because I care about the environment which I live in”.

People are forever trying to find new sources of renewable energy, so it isn’t surprising that they are especially interested in water and its versatility. Accordingly, much effort has been directed into obtaining energy from tidal and wave power, which are defined as circular movements of water molecules caused by wind that moves water surface through friction.
