Historical water use patterns are used for a variety of reasons including demand forecasting, planning for new source development, evaluating conservation measures, assist in making water resource decisions and many more.
The system’s historical annual customer demand per customer class is demonstrated in Figure 200-C below, the Sunshine Acres annual demand has historically been well within its total Water Rights allocation.
Figure 200-E below shows the seasonal demand pattern.
Table 200-05 documents the historical distribution system leakage for Sunshine Acres. All waters that cannot be accounted for are considered components of distribution leakage. Leakage is expressed as a percentage of the total annual volume produced. The goal is for Distribution System Leakage (DSL) to be less than 10%.

Section 200.18 above documents Sunshine Acres’ historical growth rate over the pasted 10-years was 0.67% annually.
Most of the growth will be limited to in-filling of existing Lots of Record for single-family residential homes within the existing plats of Sunshine Acres.
There are three (3) undeveloped Lots in the Diamond Point Airport (DPA) zone that could be developed for commercial activities.
Sunshine Acres historical annual growth rate has ranged from 0.0% to 1.6% between the years 2003 through 2018. The past 10-years, 2008-2018, annual growth rate was 0.67%. The projected Sunshine Acres growth rate for the next planning period will be 0.85%. The projected number of ERU’s is shown in Table 200-10 and in Figure 200-F below.
Using the system’s growth projection and demand projection described above, Tables 200-12 and 200-13 below demonstrate the system’s forecasted demand for the next consecutive 10-years, the 20th -year and the 50th -year of projected growth.
