Looking for advice on well water level project

Hello everyone, new to this forum, I have been messing around with Arduino toolkits for a bit, and have some basic understanding of electronics and some equipment. I worked with pre-built kits, building electronic projects based on tutorials and I love repairing old electronics. But never found a problem that I needed to solve with an Arduino.
