Sanitary Water Supply
As the laws of health become better understood, greater precautions are taken to prevent sickness. For years all evidence has been pointing to drinking water as a common source of most diseases and the principal means of spreading sickness. Every well, spring and cistern, open to surface water or walled and covered with materials through which surface water can seep, is liable to contain disease germs. Concrete walls and covers are water-tight: they afford perfect protection for both man and beast.
