Pressure needs to be consistently high enough to satisfy the customer, but excessive pressure drives up leakage, burst frequency, energy consumption, and operational costs, whilst decreasing the lifespan of network assets. Basic pressure management The challenge of accurately controlling pressure is complicated by the fact pressure varies uniquely across each network, constantly shifting with changing patterns of demand and outside events. Because of these variations, initial approaches to pressure management (such as fixing pressures, or basic time or flow modulation) do not deliver a constant stable pressure to the customer. These traditional pressure management techniques either lock in a pressure level that is too high (or too low), or are unable to respond effectively to the changing demands on the network. Advanced Pressure Management i2O Water has developed unique, patented technologies to address these challenges, overcoming the shortcomings of basic pressure management techniques with t ?YHX?????H[?X?Y?\??X?X?\?8?(?H??Y[???]???X[?Y?\???]Y?]?[???\?X?[]H[?[?[Y?[??H[???]???\???X[??H8?(?H[?X?[??H?[[?HX[?Y?[Y[???\??\?HX????H?]????]?]X[?X[[?\??[?[??8?(?H]]?X]X?[H[???[?[?\?H?[Z\?[???\??\?HX????H??H?]????\?Y?H?\??[?[X[?]\???[??\?][???\?X?\?\?X???H?]???L????][????\?\?H?[?\]YK??\?\??\?H]?[??H]ZX??H[?X\?[H?]??]Y??B???\??Y\??&\??]???[?[???]]?H???\?H]\???YY\?H?\??X?H ?XT?K?H[?\]YH?[??[?[]H?HL???\?[H\?XYH???X?H??Y?HY?[?Y?][??H???\?H[?\??\?K?H?^?[?Y?]???[Z\?[???]\??]????\??\?H K??YX?HXZ?Y?HXZ?Y?H\?\?X?H?[]Y??\??\?K???[?H?YX?[?[??\??\?H?[?]?HH???[?[?YX?[?[?XZ?Y?H]?[?[??X?X?KY?[??Y?\??\?HX[?Y?[Y[?\?\X?[H?Y[??????YX?H]?\?Y?H?\??\?H[?H?]????H ?
