Use of this data at other locations must account for <br /> elevation differences and for fictional losses <br /> 4) Flow data will change in response to future changes in the water system configuration and future changes in water demand. <br /> Map of Location <br /> L �w I 4� <br /> -... p ._es —. awosr—" .•f"2,02 .= - a, xmnsr_t <br /> 1 — 1 - ; . 1M <br /> 3 " <br /> -M node , o¢ele19.4f .. <br /> rd. :. 4 it 1 9W <br /> I <br /> 41 wl <br /> s1 <br /> 9 si SM1 <br /> P_n m1 r g 3I33171_.,El <br /> co pm ir" <br /> effi I L s i i11 <br /> a„ n <br /> pili <br /> r ®, _ 2 ;V - <br /> �� �,al pr <br /> __b „ x n ___l �. tl. �1 �Vui <br /> r`70e- . . node (1» swx <br /> we ll:34°6 Ll J 1 i e-.... aw <br /> P. r�mi. . --mom i <br />
