All the methods of waste disposal heretofore described are open to the
following objections:
1. They do not take care of kitchen slops and liquid wastes incipient to a
pressure water system.
2. They retain filth for a considerable period of time with probability of
odors and liability of transmission of disease germs.
3. They require more personal attention and care than people generally are
willing to give.
By far the most satisfactory method yet devised of caring for sewage
calls for a supply of water and the flushing away of all wastes as soon
as created through a water-tight sewer to a place where they undergo
treatment and final disposal.
