<br />demand, and to provide the required fire flows and emergency reserves. Throllghollt tht" PI~nninc
<br />.Area,.Pleasanton stores its water in a'\.1 i", vf tank reservoirs which are grouped into four main
<br />pressure zones and a number of smaller pressure zones tlllvlI!;"vllttl,,, flallllill!; A."". The main
<br />water pressure zones consist of the Lower Zone (representing &Z-.&O...percent of total demand); and
<br />three Upper Zones serving portions of the Foothill Road area in the west (the Foothill Zone and the
<br />770 Zone) and the Southeast Hills and Ruby HilLareas in the southeast (the Bonde Zone).
