This data <br /> illustrates a relatively high potential for there to be.significant-evapotranspiration (or bare soil <br /> surface evaporation) from the disposal area. However, since filter,fabric is specified over the <br /> chambers ofthe disposal area, this evapotranspiration may be impeded.. <br /> The following Worksheet is found in A Guide to Estimating Irrigation Water Needs of LandscUe <br /> :Plantings in California and contains the calculations necessary for estimating the water requirements <br /> of the wastewater disposal area landscaping, if it is preferred over the disposal area. <br /> 12 ; <br /> Chesney Consulting <br />
