Reduce Energy CostReduce Emission
These tanks could supply water during on-peak hours and be refilled during off-peak hours to minimize costs and emission.

Conclusion
Not all elevated storage tanks provide the same amount of reductions in energy consumption, financial costs or pollutant emissions. Modeling similar to what has been presented here can identify the optimal tank size and system scheduling for maximized benefit.
