§ 381.49 - Drainage and plumbing.

(a) General. There shall be an efficient draining and plumbing system for the plant and premises.

(b) Outside premises. The drainage system must permit the quick runoff of all water from buildings, and of surface water around the official establishment and on the premises; and all such water shall be disposed of in such a manner as to avoid the development of insanitary conditions at the establishment.

(c) Drainage of sewage and plant wastes. (1) All drains and gutters shall be properly installed with approved traps and vents. The sewer system shall have adequate slope and capacity to remove readily all waste from the various processing operations and to minimize or, if possible, prevent stoppage and surcharging of the system. When the sewage disposal system is a private system which is required to be approved by a State or local health authority, the applicant shall furnish the Administrator a letter from the proper health authority indicating that the sewage disposal system is acceptable to such authority.

(2) Interceptor traps which are connected with the sewer system shall be suitably located, and not near any edible poultry products department or in any area where edible poultry products are unloaded from or loaded into any means of conveyance. To facilitate cleaning, such traps shall have inclined bottoms and be provided with suitable covers.

(3) Each floor drain shall be equipped with a deep seal trap, and the plumbing shall be installed so as to prevent sewage from backing up and flooding the floor, except that floor drains in areas not regularly washed down will be acceptable without deep seal traps: Provided, That such drains are connected to secondary drainage systems discharging into a safe sink or basin (air gap) that is properly trapped and vented: And provided further, That such drains accomplish the objectives and intent of this paragraph.

(4) Toilet soil lines shall be separate from house drainage lines to a point outside the buildings unless an automatic backwater check valve is installed to prevent backflow. Drainage from toilet bowls and urinals shall not be discharged into a grease catch basin, nor shall such drainage be permitted to enter the sewer lines at a point where there might be a possibility of such drainage backing up and flooding the floor of the building.
