Underground Water Storage Tanks
FIRE CISTERNS are reliable year round water sources for fire fighting, often required when there is no central piped water supply in the area.
Providing a fire cistern 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.
The illustration on the right is one example of a common "draft" or suction type fire cistern design. (See Illustration #1 & #2)
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.
Darco manufactures both fiberglass and polyethylene underground fire cisterns and fire sprinkler reservoirs. You will find more Fire Service Cistern information and illustrations in the "Fiberglass Tanks" section: see Fiberglass Tank Concepts and in the "Polyethylene Tanks" section: see Polyethylene Tank Concepts.
