<br />Table 8 -2 provides well production data for the five wells detailed in Table 8 -1. Well production is a
<br />measure of the amount of water needed to satisfy the supply demands of customers. Well production in
<br />the City of Lino Lakes should always be greater than water sales /consumption. This is due to leakage
<br />from the system, watermain flushing, meter inaccuracy, and other un- metered uses. Well production
<br />facilities are designed to have sufficient "firm" capacity to supply the "peak day" demand of the system.
<br />The "firm" capacity is defined as the capacity that would be available if the highest capacity well were
<br />removed from service due to maintenance or failure. The "peak day demand" is the highest water
<br />production day of the year. Table 8 -2 contains the average and peak day well production volumes, along
<br />with the computed per capita well production rates for the period of 1998 - 2007. Figure No. 8 -2, Peak
<br />Per - Capita Use, on the following page, graphically depicts the annual variation in the peak day per capita
<br />rate.
