That did work, but not for long. The sonar sensor got wet in the rainy season and went out of order. Right now the solution is to place a CC camera inside the tank and watch water level live on display. Less techey solution that works :-)
Plus the motor has been automated using floating valves. But had to use 12V relays so that I don't accidentally send 220V AC inside the water tank.

- ^ Simple when explained to the user. But what works behind the scene for that solution is complex. Someone had to design the circuit for it to work.
