In the second method, water usage records can be used to estimate the base sanitary flow for the sewered population. The best time to estimate flow using this method would be when outdoor water uses are low and wastewater from a residential area can be assumed to be the same as the
Webin this study are the measurement of infiltration rate on the ground surface which will be used as a reference for determining the runoff coefficient and the analysis of calculating hydraulic conductivity in the BIH using the Porchet method to determine the optimum capacity of holes in delivering water. The result shows that with the Webmeasures a rate that is different than the observed vertical infiltration rate (for example, three-dimensional borehole percolation rate) then this rate must be adjusted by an acceptable method (for example, Porchet method) to yield teh field estimate of vertical infiltration, Kmeasured.
