In order to predict future water production requirements for the City of West Jordan, historical water use data was used to determine the appropriate factor. Historic water use for the years 2017 through 2020 as summarized in Table 2-3.
Year | Population | ERCs | Total Water Production (Acre-Ft) | Acre- Ft/ERC | gpd/ERC | Peak Day Water Production (mgd) | Peaking Factor |
2017 | 102,000 | 39,935 | 22,200 | 0.56 | 496 | 43.6 | 2.20 |
2018 | 102,500 | 40,436 | 23,062 | 0.57 | 509 | 53.3 | 2.59 |
2019 | 103,250 | 40,943 | 20,853 | 0.51 | 455 | 46.0 | 2.47 |
2020 | 103,762 | 41,456 | 23,718 | 0.57 | 511 | 43.9 | 2.07 |
Based on the information in the table above, BC&A determined that the highest annual water use per ERC occurred in 2020 at 511 gal/day/ERC. The peaking factor from annual average to peak day water use was also calculated over the same span. The max peaking factor occurred in 2018 and was 2.59.
