  6. 6. At the risk of sounding rather naive, we dare to say that at Oras, welove water like some people might love, say, gold. Naive or not, thislove affair is why we create no technology without its foundation inecology. It all actually dates back to 1976; the year that we createdour first single lever faucet, strictly designed to save water andenergy. That became the core of Oras, the ideology through whichhave strived to create the most user friendly and contemporarilydesigned faucets. So that you can best enjoy the great luxury calledwater. The most valuable commodity in the world.Over the years we have learned a lot about water and especially theremarkable costs of wasting it. That’s why this guide exists: we wantto share what we know with you. Not only because saving water andenergy is good, essential, for our planet, but because by doing so, youcan save money.

  9. 9. Sometimes a faucet is not just a faucet. It can be a money saving machine. And a huge improvement on the comfort of living.
  10. 10. Saving water is a big issue. Makesure you can handle the pressure.Stabilizing the pressure level in a consumer water system ensures that the water flows from faucetsin the most unfavorable apartments – usually the ones at the longest distance – meet the flowstandards. However, in this case the water flows from the faucets on the lowest floors still exceed thestandards, since there the pressure level is higher. These excessive flows can be cut with the rightchoice of faucets. Such as faucets equipped with an Eco-button.Oras Optima faucet with 75–90 % of the maximum They are economic, because the Eco- flow, depending on the place of con- button cuts the overflow without restrict-The control valve of the Oras Optima sumption.

  11. 11. Oras Electra touchless faucet.Probably themost luxurious way to enjoy water while saving it. And energy, too. Sounds great, is priceless. Oras Electra, Oras No. 6150F The touchless faucet for wash basins improves hand hygiene and saves water. Water flows only when hands are under- neath the faucet.
  12. 12. And now for the cooltechnology part: a faucetthat prevents the waste of water.A significant part of water consumption involves waste-running of water. In other words, turning offthe faucet for the time of washing when water usage is not necessary, appears to require an effort.Because of laziness perhaps, or just old habits. Furthermore, in public premises the consumption of water is not perceived as personal item of expenditure and as a result, the wasting of water is common. We simply don’t give it a thought. However, there is a faucet technology available that minimizes waste-running of water and is thus especially suitable for these points of water consumption.Oras Electra consumption of water was measured for ing a hand in front of the sensor withinOras Electra is a faucet especially a month before and after the replace- the recognition range.

  15. 15. Water consumption application. by objects of The average consumption of household water by an inhabitant of an apartment building is about 180 litres per day. The inhabitant of a pri- vate house usually manages with a quantity about twenty litres less. Variations in consumption are nevertheless big: Variation 90-270 l/res./day Average 155 l/res./day Target 130 l/res./daySource: Motiva, 2006
