Sizing Recommendations
If used efficiently, cistern owners will still consume an average of approximately 30 gallons daily per person. Using this math, a family of four being conservative with their water will use an average of 120 gallons daily, or 3600 gallons monthly.
Depending on your water usage, number of people in your household, and if you have a secondary water source such as rainwater collection, you may be able to use a smaller tank. Water can become stale if stored for too long, so having it filled frequently will create a more enjoyable experience.
Tracking Your Water Level
There are some traditional methods available of measuring the water level of a cistern tank, however, they tend to be much less accurate that modern technological options. The stick method consists of dipping a long stick or pole into your tank to see how deep the water level is. Others simply guess based on time and familiarity with their usage.
Our recommendation would be the PTLevel which can accurately measure your water level and be tracked on your phone. This allows to you access real-time measurements, and order the exact quantity of water you need.
