Drinking water treatment and distribution system operation consumes a large amount of electricity.
00:10
Optimizing energy usage can provide benefits to water quality as well as savings to customers.
00:17
To streamline efficiency, many drinking water utilities rely heavily on supervisory control and data acquisition (SCADA) systems.
00:26
These systems are programmed to increase operational efficiency, anticipate fluctuations in demand patterns for pump control,
00:34
react to emergencies, and monitor storage volumes, among a host of other monitoring parameters.
00:40
The InfoWater Pro Scheduler app can be used to assist water distribution system operators in selecting cost-effective pumping policies,
00:48
both to reduce operational costs and to provide more reliable operations.
00:53
These results can then be translated to SCADA systems (by separate means outside of InfoWater Pro) for practical use.
01:01
Before running the Scheduler, it is important to consider where your savings can be realized
01:06
based on the constraints and variables of your water distribution system.
01:10
For example, in all likelihood optimizing your pumping system may not work at all times for every day of the year.
01:17
In a maximum day scenario, your pipelines and pumps may already be at their maximum capacity,
01:23
or storage may be at its minimum capacity.
01:26
In these cases, you can still look for key conditions that may save you money.
01:30
Some other questions to consider when thinking about optimization:
01:35
What is the system configuration?
01:38
It might be difficult to optimize a system with no storage.
01:42
For example, in a pump-only system or a consecutive wholesale system without storage, demand equals the water supplied.
01:50
Is your electricity billing rate tied to your highest usage in the year?
01:54
Can you purchase energy at a wholesale or reduced rate based on previous usage?
01:60
Can you pump during off-peak hours?
02:02
Have you considered cost penalty weighting factors?
02:06
For example, if there were no penalties for low junction pressure or pump flow,
02:10
the most cost-effective solution would be to never run the pumps.
02:14
Of course, this is not a realistic or workable solution.
02:18
Anything that should be optimized must be built into the Scheduler setup.
02:23
This includes any control valves or pumps filling a tank.
02:27
What is the pumping objective of your water distribution system?
02:31
Ask yourself: Do you want to deliver head and flow to a tank, supply demands, or a combination of these?
02:39
Do you need to maintain storage?
02:41
What is the ideal cycling of the water system?
02:44
What is your optimal pumping schedule?
02:47
Think about how to satisfy your system hydraulic and water quality criteria
02:52
while trying to minimize electrical costs for consumption and demand.
02:56
Maintenance costs also need to be considered.
02:60
For instance, how will running pumps alternatively or in a rotating sequence
03:04
reduce wear on motors, bearings, impellers or switchgear?
03:10
Having a thorough understanding of many of these considerations can help you get the most out of the Scheduler app.
