Use of this data at other locations must account for <br /> elevation differences and for frictional 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 /> _-`� 3220 (P �� f . \., <br /> ia�3224J + • '8 ! \ t' <br /> r ¢ \ i <br /> ` t 3 3231 2107 - <br /> Li <br /> 3228 3228 I-- L. <br /> a _I a <br /> 0D8 t Y32 µu. • r°..f1 n 2121 �re Y . ° <br /> 32 LLL'�� <br /> b wax... <br /> 33 _ f .....DST..._ �' _ _ _..__.A..J t U 5T ✓ 33RD.-S�p'`w� _:, <br /> .o,..._._._.._ .. .: _. <br /> ( <br /> y,-a o v a r• <br /> ° zone _ �4 330„ - --.
