Simple MultiSIM circuit design

Very simple circuit!

Need a simple circuit design written and tested in MultiSIM.

Circuit basically takes 0V to 5V input and and ouputs either 20V or 0V (on or OFF) depending on the input. Uses simple comparators and opamps.

Must show Vinput Vouput graphs, explanation, and provide circuit files.

Here is more detailed Scenario:

You want to design a circuit that automatically fills a bowl of water for your cat while you are on vacation. When the water level gets too low, the circuit turns on a pump that lets water into the bowl. When the bowl is sufficiently filled with water, the circuit shuts off the pump automatically. You have already designed a water meter that puts out a signal of 0 to 5 V DC depending on whether the bowl is empty (0 V) or full (5 V). You want the water level to stay partially full (at least 1 V) but not too full (4 V). The pump needs +20 V DC to turn on. Design a circuit that takes 0 to 5 V from the water meter as

the input, and 20 V as the output, to turn the pump on and off as appropriate.
