Water cisterns are generally used at sites where there is no viable access to well water and no availability of municipal services. There is growing use of low-pressure pipe for delivery of municipal water services, which requires a form of water cistern known as a ‘trickle tank’. A common cistern is filled by removing an access cap at grade and placing a supply hose that is connected to a tank truck. A trickle tank is filled via a connection to the municipal service, usually controlled by a float valve within the tank.

Cisterns are typically buried with approximately 4’ of earth cover in order to keep the water cool and clear while protecting the tank and contents from freezing in winter. A submersible jet pump in the cistern is connected to a pressure tank and control switch located inside the house. An alternative arrangement is to locate a variable demand pump in the tank. This option provides a simpler arrangement and constant tap pressure, but at a higher cost.

One important factor to consider in sizing a cistern is the expected water demands of the household, which is influenced by the number, age, gender, and behaviors of the residents, as well as by the characteristics of the installed plumbing fixtures. Another important sizing factor is the hauling capacity and pricing patterns of commercial water haulers serving the area. Many districts in Alberta are served by water haulers with 2,000 to 3,000 gallons of capacity. More than a 1-month supply in the tank is not desirable; less than a 1-week supply is inconvenient.
