A perfect accesory to a water cistern

If you have a water cistern, this is the tool to help you manage it. We prefer to keep our cistern on the fuller side so are always planning out our water hauls. Having this system makes this task so much easier as we now have our water level at our fingertips and know exactly how many hauls we need to do. No more stress of having our water level get too low!

Excellent product far exceeding what's out there

Great product. Very well designed. Takes the guesswork out of knowing our cistern level. We will never run out of water again as the software will email and text us when the tank gets to a user set level, as well as a daily message with volume remaining, allowing us time to order more water from our hauler. Our water hauler even offered to get the low level notification directly to remove the need to contact him. The usage chart allows a visual representation of actual water consumption over a given period of time which is great as well as providing the systems overall health. This product is well worth the investment and the customer support is top notch should you ever need assistance.
