<br />Table 7-4 shows that in normal years, the City's supplies are adequate to meet projected demands.

<br />7.1.3.2 Water Service Reliability - Single Dry Year
<br />In Chapter 7 of its 2020 UWMP, Zone 7 has indicated it can meet retailer demands during single dry years
<br />through 2045. Therefore, Zone 7 supplies to the City are assumed to equal the City's projected potable
<br />water demands after accounting for the City's GPQ. Recycled water supply is assumed to be unaffected
<br />by the dry condition. Table 7-5 shows that the City's supplies are adequate to meet projected demands
<br />during single dry years.
