Farmers' Bulletin No. 1227 United States Department of Agriculture

SEWAGE and

SEWERAGE

of FARM

HOMES

DISPOSAL OF FARM SEWAGE in a clean manner is always an important problem. The aims of this bulletin are twofold: (1) To emphasize basic principles of sanitation; (2) to give directions for constructing and operating home sewerage works that shall be simple, serviceable, and safe.

Care in operating is absolutely necessary. No installation will run itself. Continued neglect ends in failure of even the best designed, best built plants. If the householder is to build and neglect, he might as well save expense and continue the earlier practice.
