A large city has high flow rates during the wet season of the year. Flow during the dry period of the year, when infiltration is negligible, averages 120,000 m3/d (31.7 mgd). During wet weather, groundwater levels are elevated, and the flow averages 230,000 m3/d (60.8 mgd), excluding days during and following significant rainfall events. Hourly

†The fixture units listed for shower heads are based on a flow rate of 3 gpm. These units should be corrected for other flow rates. Multiply the fixture units by Correction Factor “C” from the formula: C = G x .33, where C = Correction Factor and G = gpm of shower head being used. Example: Shower head 4 gpm = C = 4 x .33 or 1.32.
