Potable Water Storage Tanks

Compare potable water storage tanks for emergency reserves, cabins, off-grid homes, and other drinking-water storage applications. This tank-only collection brings together current Peabody ProChem models from 50 to 1,000 gallons, including a 140-gallon square water-only option.

Match capacity to the space you have

• 50 and 100 gallons: compare smaller cylindrical models when available space limits your installation.
• 140 gallons: consider the square water-only model when its footprint better suits your layout.
• 500 gallons: plan for a larger centralized water reserve.
• 1,000 gallons: compare the 64-inch and 73-inch diameter models. Equal capacity does not mean an identical footprint or height.

Use our Emergency Water Storage Calculator and Planning Guide to estimate your reserve before choosing a capacity.

Check the exact model and configuration

Review each product page for dimensions, available colors, lid access, fittings, material specifications, potable-water suitability, and shipping details. Confirm that the selected configuration fits your application. Allow room for delivery, installation, inspection, and maintenance, not just the tank itself.

Storage is one part of your water plan

A storage tank does not purify water. Begin with water suitable for its intended use and follow appropriate storage and maintenance practices. If you plan to collect rainwater, evaluate the complete catchment and treatment system separately. These listings are tanks, not complete rainwater-harvesting or purification kits.
