Examples of ET adjustment factor in a sentence
These total savings of 70,000 acre-feet per year when normalized by the projected 2020 population (43.8 million) yields between 1 and 2 GPCD.Our estimate only captures the extra savings that will result from lowering the ET adjustment factor, not the total savings from having a landscape designed according to the Ordinance and irrigated within budget relative to a landscape not designed and irrigated according to the Ordinance.
If these service areas intend to retrofit at a faster pace than was assumed by the Comprehensive Evaluation, then the above estimates may not hold.10http://www.owue.water.ca.gov/landscape/ord/ord.cfmWe estimate that reducing the ET adjustment factor from 0.8 to 0.7 (12.5% reduction) will roughly generate savings of 1-2 GPCD by 2020.
Alternatively, the same ET adjustment factor (160%) could be attained with 50 percent irriga- tion efficiency and no allocation of rainfall to cover plant needs.
Per the Water-Efficient Landscape Ordinance, the evapotranspiration (ET) adjustment factor for recycled water use areas shall not exceed 1.0. However, regular monitoring through system checks or visual indicators of runoff are necessary for the site supervisor to confirm the application rate does not exceed soil infiltration rate.
A combined plant mix with a site-wide average plant factor of 0.5 (indicating a moderate water need) and average irrigation efficiency of 0.71 produces an ET adjustment factor of (0.7) = (0.5/0.71), which is the standard of water use efficiency generally required by this water efficient landscape ordinance and the guidelines, except that the ETAF for a special landscape area shall not exceed 1.0.
