Ambient Water Information SystemsAmbient Water Information SystemsGoal Information Conveyed to
IndividualTarget Outcomes
Reduce Consumptive Use Waste
Individual feedback on weekly cumulative water use, water pricing data, and/or system demand. Information regarding irrigation consumption best practice based on weather and/or climatic data. Indicating and alerting individuals to changes in local regulatory actions relative to consumptive use such as irrigation bans.
Reductions in consumptive use and changes in timing of use as a result of feedback and awareness of impacts.
Optimize Storm Water Control Usage
Information on how to optimize use of storm water controls that require individual participation (e.g., rain barrel, blue roof, or cistern management).
Optimal use of Rain Barrels or other controls which require operator control and decision making (e.g., drain or leave full) for volume control in urbanized areas.
Reduce CSO Impacts
Information regarding receiving water quality and CSO status in combined sewer areas.
Consumptive use changes based on direct impacts on receiving waters. These could include but are not limited to timing or other decisions about consumptive use and decisions about waste water quality (e.g., what do I send down the drain at a given time).
