CHAPTER 7
SANITARY DRAINAGE

User note:
About this chapter: Chapter 7 regulates the methods and piping systems that remove water that has served a purpose such as flushing
water closets, bathing, culinary activities and equipment discharges. The types of materials, drainage fitting and the connection methods are
covered for these systems that begin at the receiving fixtures and end at the point of disposal for the liquid waste. A design method for a grav-
ity flow system of vertical and horizontal piping is provided based on the probability of flows from specific fixtures. Vacuum and pumped types
of liquid waste removal methods are also regulated by this chapter.
