## Abstract

A study was undertaken to document peak flow and load conditions in treatment plants. Data were analyzed from 11 plants ranging from 0.01 to 1.75 ${\rm m}^{3}/{\rm s}$. Equations were developed to relate average peak 4- and 8-hour, average peak month and day, and extreme peak month and day to average annual flow, biochemical oxygen demand, suspended solids, ammonia nitrogen, and total phosphorus loads. These equations may be used, with due regard for local conditions, for peak estimation for cities having local conditions, for peak estimation for cities having separate sewer systems and annual flow rates between 0.004 and 4.4 ${\rm m}^{3}/{\rm s}$.
