Fire Cisterns &
Underground Fire Cisterns
FIRE CISTERNS are reliable year round dedicated water sources for fire fighting, often required when there is no central piped water supply in the area.
Providing a fire cistern or firefighting water storage tank in compliance with the local fire department’s design and storage volume requirements may reduce insurance premiums and create a valuable emergency water resource available to the entire community.
The NFPA (National Fire Protection Association) has published guidelines regarding the location and volume of an appropriate fire cistern, based on the property or structure it is designed to protect. Please consult with your local Fire Chief about any such project before you start planning for an underground water storage tank.
Illustration #1 is an example of a common “draft” or suction type fire cistern design.
Illustration #2 is a minimum lift design for high elevation sites.
Illustration #3 is a mounded bury allowing full gravity discharge of the entire tank volume.
There are many different possible layouts; some will require drafting, while others may provide a gravity flow or pumped discharge. Work with your Fire Department to ensure the system will work as planned when needed.
