: I am interested in cisterns. Any information and/or products you have would be appreciated. : Thankyou.Cisterns can be any type of holding tank. Usually they are made of reinforced concrete. They can be cast in place or manufactured and delivered (max. size about 3000 gallon, anything larger is too heavy for a truck). I manufacture cistern water level alarms, set the device at a certain level and an alarm sounds when the level drops below. For maore info. email me at [email protected] this helps, John
