Capacity: 40 gallons with a 6″ wide cap and built-in 2″ drain plus a 3/4″ garden hose port. Best for trucks, tractors, or trailers needing reliable irrigation or cleaning water storage. Its translucent, chemical-resistant poly helps track level at a glance. Limitation: smaller capacity means more frequent refills for large irrigation tasks.
RomoTech 125 Gallon Polyethylene Storage Tank with Legs
Capacity: 125 gallons with UV-stabilized, rust-proof polyethylene. Best for elevated or raised setups in farms or workshops; the leg design aids drainage and accessibility. This tank is a middle-ground option between compact portable units and large farm tanks. Caution: verify leg height compatibility with intended installation space.

Capacity: 1000 gallons with UV-resistant, virgin HDPE and dark color to block light, reducing algae growth. Best for rainwater harvesting, farm bulk storage, or emergency supply where space permits vertical tanks. Features include two 16″ manway lids for top-down access and 1.5″ and 2″ fittings for optimized fill and drainage. Caution: large footprint requires suitable installation area and secure anchoring in windy locations.
Buying Guide
What capacity should I choose for bulk storage?
For reliable bulk storage, larger tanks like 1000 gallons reduce refill frequency in farming or irrigation workflows. If you need mobility or space efficiency, consider 100–125 gallon tanks as supplementary reservoirs.
What materials and durability matter?
Look for UV-stabilized, rustproof polyethylene or HDPE that resists sun exposure and outdoor conditions. Virgin polyethylene is preferred for drinking-water safety, and BPA-free formulations support long-term quality.
How important are fittings and accessibility?
Oversized lids, built-in bulkheads, and standard NPT outlets simplify refilling, siphoning, and hose attachment. Ensure drainage points meet your site’s plumbing or irrigation needs.
Where will the tank be used?
Vertical tanks save space when floor area is limited, but require secure mounting. Horizontal tanks are often easier to move or transport, ideal for trailers or work sites. Consider shade or covers to minimize algae growth.
What about safety and compliance?
For drinking-water storage, choose tanks that are FDA/NSF-compliant or clearly rated as safe for potable use. Verify certifications and local regulations relevant to your project.
Usage scenarios
- Farm irrigation and livestock water supply
