Fig. 2. Infiltration rate (IR) per cycle and average effluent temperature (T) per cycle measured in large scale recharge basins at the Shafdan wastewater treatment plant across a 4-yr period. Curves were obtained by smoothing (five-point moving average) of the measured data. Dashed lines indicate recharge regime change in Basin 102 on 1 July 2000 (see Table 1). F = fall, Sm = summer, Sp = spring; W = winter.
