Title: Easy Water-Saving Method for WC

The idea is based on the fact that most households have WC cisterns that operate with too much water. To easily change this technical deficiency, simply put a half-liter PET bottle filled with water into the cistern. Water consumption will be reduced by half a liter with each flushing. Projected onto a community of 1000 persons and 3 flushings a day, 547.500 liters of drinking water can be saved a year. The installation costs are nonexistent and there are only benefits. The calculation for Austria results in an annual reduction of water consumption by 4 billion liters of drinking water.
