Firefighting demands must be considered in any municipal water system design.
A1 though annual vol urnes requi red for fi re purposes are small, the demand may
govern the design of parts of the distribution system, treated water storage
facil iti es, and pumpi n9 equi pment. For the 1986 servi ce area popul ati on of
67,514, the required fire flow is 7700 gpm. This population figure includes
customers outside the City. At the projected population of 109,241, in the
year 2015, a fi re flow of 9500 gpm is necessary. These fi gures are based on
the recommendations of the National Board of Fire Underwriters.

When sizing distribution systems, the typical practice is to assume a
coincident draft during firefightin9 demand equal to the maximum daily
