Abstract
Abstract A water system in which chlorine is proportionally supplied at a rate which will not render the water unpalatable, the water thus chlorinated, being filtered through a filter, said system, from the addition of said chlorine until it reaches service having a traversal rate at the maximum contemplated draw of water from the system, sufficient to enable the chlorine at the prevailing concentration, to thoroughly destroy all existing germs. Automatic starting of flow upon opening of a service line, and the provision of automatic backwashing for the filter, render the system entirely automatic.
