RotoTank 4600L Vertical Water Tank, UV-Stabilized Polyethylene

RotoTank 4600L Vertical Tank

The RotoTank 4600L Water Tank provides a high-capacity storage solution for potable water and irrigation systems on residential or commercial sites. This vertical cylindrical unit uses food-grade polyethylene to maintain water quality over long durations. It fits standard plumbing configurations for gravity-fed or pump-assisted setups.

Built for the Job

Contractors install these units on reinforced concrete plinths to ensure structural stability during full-load conditions. The 4600-liter capacity suits multi-unit residential blocks or medium-scale agricultural irrigation projects. Plumbers appreciate the pre-marked flat spots for drilling inlet and outlet connections. The rotationally molded construction ensures a seamless body, which eliminates weak points common in welded alternatives. This design handles the high internal hydrostatic pressure of nearly five tons of water without bulging or cracking.

• Bulk potable water storage for construction site offices and labor camps.

• Rainwater harvesting collection for landscape irrigation and greywater use.

• Buffer storage for borehole systems to manage peak demand in facility management.

Product Highlights

UV-Stabilized Construction

The outer polyethylene layer contains carbon black or UV-inhibitors to prevent brittleness from sunlight.

Food-Grade Certification

• Inner liner prevents algae growth and maintains water purity.
• Material complies with international standards for drinking water contact.

Technical Specifications

What’s Included

• 1 x 4600L Cylindrical Storage Vessel

• 1 x Heavy-duty threaded manhole cover

On-Site & Workshop Notes

• Ensure the mounting surface is a level, smooth concrete slab at least 100mm thick to prevent base deformation.

• Use flexible couplings for pipework connections to accommodate slight expansion and contraction of the plastic walls.

• Verify local building codes for tank placement relative to property boundaries and drainage lines before final installation.

• Keep the threaded lid tightly closed when not in use to prevent contamination from dust, debris, or pests.
