demand. For high value districts, fire flow capacities must be maintained for
10 hours; therefore, the required fire flow capacities for 19S5 and 2015 are
4.6 mgd and 5; 7 mgd; respectively. When added to the maximum daily demand;
these capacities are still much less than the peak hourly demand.

Even though fi re flow requi rements do not control the si zi ng of the overall
di stribution system, they do estab1 hh minimum capacities for the extremities
of the system. The City of Greeley uses population density and hydrant
spacing for determining the fire flow capacities of each distribution pipeline;

Offices. The rating is based on a scale from one to ten, with Class 1 being
the highest rating possible.
