RotoTank 4000L Cylindrical Water Tank, UV-Stabilized Polyethylene

RotoTank 4000L Cylindrical Tank

The RotoTank 4000L Water Tank provides a high-capacity liquid storage solution for residential, agricultural, and commercial job sites. This vertical storage unit utilizes food-grade, high-density polyethylene (HDPE) to ensure safe containment of potable water. The cylindrical profile distributes hydrostatic pressure evenly across the walls for long-term structural stability.

Built for the Job

Site supervisors and plumbers specify this 4000-litre capacity for medium-scale rainwater harvesting and backup water systems. The vertical orientation minimizes the footprint on-site while providing significant volume. It is frequently used as a primary buffer tank in areas with inconsistent municipal supply or for temporary site utilities during construction phases.

• Rainwater collection from residential and commercial roof catchment areas.

• Agricultural irrigation storage for greenhouses and small-scale livestock watering.

• Backup potable water storage for multi-unit housing complexes.

Product Highlights

Seamless Construction

The unit is manufactured through a rotational molding process, creating a single-piece body without seams to prevent leaks.

Material Integrity

• UV-stabilized polyethylene prevents plastic degradation and brittleness from direct solar exposure.
• Opaque wall construction blocks light penetration to inhibit internal algae growth.

Technical Specifications

What’s Included

• 1 x 4000L Cylindrical Water Storage Tank

• 1 x Heavy-duty threaded manhole cover

On-Site & Workshop Notes

• Always install the vessel on a reinforced concrete plinth that is perfectly level and clear of sharp aggregates.

• Use flexible hose connectors between the tank outlet and rigid pipework to accommodate minor settling or pump vibration.

• Ensure the tank is properly vented to prevent vacuum collapse during high-flow discharge or pressure buildup during filling.

• Check local building codes for required setbacks and drainage overflow management before final positioning.
