How are cisterns made?
Beside this, how were cisterns built?
Cisterns are generally circular structures made of brick or wood. Ranging from 6 to 10 feet in diameter and 7 to 12 feet deep, some were built and then lowered into the ground, while others were constructed in the ground itself.
Also to know, how a cistern system works?
The cistern (upper tank of water) drains through a valve in the center through the force of gravity. When you flush, the cistern has to refill automatically from a kind of faucet on the side and the refilling operation has to last just long enough to fill the tank without making it overflow.
Advise everyone that the cistern is being cleaned and disinfected and not to use the water. 3. Store enough water to last the household/business for up to 24 hours.
