Tank material	Advantages	Disadvantages
Plastic
Fiberglass	Commercially available Alterable and movable (modular) No leak fittings Durable Minimal maintenance needed Light weight	If aboveground, must be sited on smooth, solid, level footing Expensive in smaller sizes
Polyethylene, polypropylene	Commercially available Alterable and movable Affordable Available in a variety of sizes Easy to install Little maintenance	Can be degraded by UV If aboveground (outdoors), painted or tinted Can be insultated and heat traced.
Barrels and trash cans	Commercially available Inexpensive	Must use new cans Small storage capacity Rarely installed correctly May lead to foundation water issues
Metal
Galvanized steel tanks	Commercially available Alterable and movable Available in variety of sizes	Possible corrosion and rust Must be lined for potable use Only above-ground use Must be insulated and heat traced
Steel drums (55-gallon)	Commercially available Alterable and movable	Verify prior to use for toxics Corrosion and rust can leach metals Small storage capacity
Concrete and masonry
Ferroconcrete	Durable Versatile Suitable for above- or below-ground installations Can be incorporated into the foundation of a building.	Potential to crack and leak Permanent
Monolithic/poured-in-place	Durable Suitable for above- or below-ground installations Neutralizes acid rain Can be incorporated into the foundation of a building.	Potential to crack and leak Permanent Need drainage in clay soil
Stone, concrete block	Durable Keeps water cool in hot weather	Difficult to maintain and sanitize Permanent Expensive to build Could harbor biofilms
Wood
Pine, redwood, cedar, cypress	Attractive Durable Can be disassembled Available in variety of sizes	Expensive Require skilled technician to build Not for use in hot, dry conditions Can be leaky Only above-ground use Not as easily sanitized
