COSNTRUCTION OF A WATER-SAVING AND RAIN WATER-EXPLOITING UNIT

摘要

Novelty: A water-saving and rain water-exploiting unit is disclosed. Constitution: One at least tank (fig.1-4), a piping system conducting rain water from the gutter (fig.1-1) to the tank (fig.1-4),a special network distributing water to undrinkable water supplying points (fig.1-13), (fig.1-14), (fig.1-15), a tight access port at the cistern (fig.1-28), an overflow level provision (fig.1-5), a gate valve for the potential emptying of the tank (fig.1-6), a by-pass gate valve (fig.1-16) and a network conducting the water to the street (fig.1-19). Advantages: Water filtering before storage and, thereby, use thereof (fig.1-3) in basic daily needs without wasting the drinkable water what implies savings in money; good water filtering of the rain water exiting from the tank (fig.1-8); full control of the tank (e.g. pressure control via an immersed pressure meter (fig.1-26) and water level control via a float (fig.1-27)).
