The Enduraplas 1320 Gallon Vertical Rainwater Harvesting Tank is a dark brown vertical storage tank built to collect and hold captured rooftop runoff for irrigation, livestock, and non-potable household reuse. It stands 74 inches tall inside an 82 x 82 inch footprint, so before you order, mark out that 82-inch envelope on the pad and confirm the space clears gutters, downspouts, and any first-flush plumbing you plan to route into it. The opaque dark brown walls block sunlight, which helps suppress algae growth in stored rainwater over long holding periods.
Will it work for your site?
Nominal capacity is 1,320 gallons. Filled to the top with water, the tank and its contents weigh roughly 11,009 pounds, and that full-water weight is the number that governs your foundation. A tank this size needs a level, continuous, load-rated pad; a poured concrete pad is the standard approach for above-ground polyethylene tanks of this weight. Our concrete pad sizing guide walks the ACI 360R-10 framework for exactly this decision, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 1,320 gallons matches your catchment and draw.
Specifications and fittings
Color is dark brown. Footprint is 82.0 x 82.0 inches with a 74-inch height, and full-water weight is approximately 11,009 pounds. The technical drawing on this page documents one 1-inch NPT bulkhead fitting as the outlet. That single 1-inch NPT bulkhead is the only penetration shown in the fact set, so confirm or field-add your inlet, overflow, and vent penetrations rather than assuming they arrive pre-installed. Match your delivery and outlet plumbing to the 1-inch NPT connection.
Sealing and the mistake to avoid
A bulkhead fitting seals with a gasket against the tank wall, so verify the gasket or O-ring is rated for the stored water, and use thread sealant or PTFE tape on the NPT threads only, not on the bulkhead gasket face. The bigger mistake is the foundation: do not undersize it or set this tank on bare or uneven ground. At about 11,009 pounds full, an unlevel or under-built pad lets the shell load unevenly and shortens tank life. Confirm the pad is level and rated for the full weight before you fill. This tank is rated for non-potable water and rainwater storage; a specific-gravity rating is not published for it, so if you are considering a denser liquid, select a different, SG-rated tank instead.
Rainwater harvesting layout
Plan your inlet, overflow, and first-flush diverter around the rooftop rainwater harvesting layout you are feeding. If you are building the diverter side of the system, the first-flush diverter sizing guide and the rainwater harvesting sizing by state reference cover collection sizing and the regulations that vary where you install. For rural fire-water reserve planning, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
