Zero Municipal Water Toilet

Most of your water usage does not have to be drinkable water. To save money on water and sewer costs use non-potable water in your toilet. Use a NodeMCU controller, ultrasonic sensors, 55 gal plastic tank, RV type pumps and 4 channel relays to create a fully automatic system to fill your toilet for free. Water sources are a shallow well and water from a condensing gas furnace. For complete details go to: 6. Zero Municipal Water Toilet https://sites.google.com/site/nodemcu12e/#zero
