The Right Stuff?The Right Stuff?
▼ Is your organization collecting and keeping the right kind of information?
▼ Is this information being analyzed and summarized?▼ Are these results being shared with others in your
organization who need them?
Goal SettingGoal Setting
▼ Water Demand Forecast Information How do you do this without good historical
information? Number / type of connections Water produced / used Service area capacity
Goal SettingGoal Setting
▼ Water supply characteristics How do you do this without data regarding:
Amount of water produced Water levels in your wells (including drawdown) Knowledge of maximum daily demand Trends
Goal SettingGoal Setting
▼ Water system characteristics Are you approaching limits of other system
facilities on peak days? Equalizing Storage Booster Pump Stations Transmission / Distribution System
