Drain water and electricity?

electricity consumption is very low for two reasons:
The device contains sensors that make the device work temporarily when there is a shortage of desalinated water in the tank.
The wattage the device needs is only 25 volts, which is a very low power rating
Drainage depends a lot on 3 things:
The level of cleanliness of the water at the source (the reservoir), the lower the cleanliness, the more invalid water will be discharged
The rate of dissolved solid salts in the water, the more salts, the more unsuitable water drainage ranges between 70% to 150%.
The average daily water consumption, the higher the consumption, the greater the invalid water drainage
