RotoTank 500L Water Tank, Cylindrical Vertical, UV Stabilized Polyethylene

RotoTank 500L Vertical Storage Tank

The RotoTank 500L Water Tank provides a compact and durable solution for potable water storage in residential or light commercial settings. This vertical cylindrical unit utilizes high-quality food-grade polyethylene to ensure safe water containment. It serves as a reliable backup system for areas with inconsistent municipal supply or as a primary reservoir for small-scale site requirements.

Built for the Job

Plumbing professionals and site supervisors select this storage vessel for its small footprint and high structural integrity. The rotational molding process creates a seamless body, which eliminates the risk of joint failure or leaks common in fabricated alternatives. Its vertical orientation allows for installation in tight spaces where horizontal footprints are restricted. This reservoir is frequently integrated into rainwater harvesting systems or used as a header tank for gravity-fed plumbing circuits. The thick walls withstand the hydraulic pressure of a full 500-litre load without bulging or deformation.

• Residential backup water supply for kitchens and sanitary facilities.

• Rainwater collection for small domestic or commercial outbuildings.

• On-site water stations for construction crews and mixing stations.

On-Site & Workshop Notes

• Ensure the 500-litre unit is placed on a flat, level concrete plinth to prevent base cracking.

• Check all threaded fittings for proper sealing before filling the polyethylene reservoir.

• The black inner lining helps prevent algae growth by blocking light penetration into the water.

• Standard PVC or PPR pipe fittings are compatible with the pre-molded connection points.
