Water level management system

A method for managing a water level of a body of water, the method comprising:

• determining, by a water sensor, the water level in a static pipe, the static pipe being in fluid communication with the body of water;
• receiving, at a processor, a signal sent by the water sensor, the signal indicating a low-water-level condition of the body of water;
• and
• causing, by the processor, a fill valve to open such that water is added to the body of water;
• wherein causing the fill valve to open includes discharging power from a battery controlled by the processor, and
• wherein determining the water level comprises sending a first sound wave and, based on measuring a return of the first sound wave, sending a second sound wave having a different amplitude than the first sound wave.

A water level management system, comprising:

• a water sensor positioned to detect a water level of a body of water, the water sensor configured to send a first sound wave and, based on measuring a return of the first sound wave, send a second sound wave having a different amplitude than the first sound wave;
• a processor configured to receive digital signals from the water sensor;
• a memory storage;
• a battery configured to be charged by a low-power data channel;
• and
• an ultraviolet light positioned to illuminate at least a portion of the static pipe,
• wherein the processor is configured to, based on receiving a signal from the water sensor indicating a low-water-level condition of the body of water, cause a fill valve to open such that water is added to the body of water.
