Primary Building Materials: Tires, rammed earth and concrete

Description:  Cisterns can be constructed in numerous capacities to keep water on site.  Ideally for rain water catchment, a cistern can supply water for the total consumption for the site, as well as being filtered and treated for potable water.  Building the cisterns using tires and rammed earth minimizes the amount of concrete required, which considerably reduces construction costs.  The size of the cistern can be large or small depending on site needs, average rainfall, and construction budget.
