Precision Rotomolding & 100% Virgin Food-Grade HDPE Polymer Engineering
ROTATIONAL MOLDING SPECIFICATION

Uniform Wall Thickness & Jointless Monolithic Shell

Our rotational molding manufacturing process ensures uniform wall thickness with zero joints or weld lines. Using 100% virgin food-grade polymer granules, expanded foam insulation, and carbon black UV barriers, each water tank is built for superior tensile strength, weather resistance, and hygienic drinking water storage across Bihar.

Zero Toxic Leaching UV Sun-Shield Layer Thermal Foam Core
100% Virgin Food-Grade Polymer

100% Virgin Food-Grade Polymer

Molded exclusively from pure virgin polymer granules with zero recycled scrap. Non-toxic, non-leaching inner surface keeps stored drinking water fresh, odorless, and pure.

Multi-Layer Thermal Shield

Multi-Layer Thermal Insulation

Engineered middle foam layer creates a thermal barrier that resists heat transfer, keeping stored water significantly cooler during extreme North Bihar summer heatwaves.

UV Sun-Shield Barrier

UV Sun-Shield & Algae Barrier

Outer layer enriched with high-grade UV stabilizers prevents plastic breakdown from direct sunlight exposure, while carbon black barrier blocks light to halt algae growth.

Heavy Duty Ribbed Wall Strength

Heavy-Duty Ribbed Wall Strength

Precision rotational molding ensures uniform wall thickness and circumferential reinforcement ribs for superior resistance against hydrostatic water pressure and wind.

Rotomolding Manufacturing & Purity Process

1

Raw Material Inspection

100% virgin food-grade polymer granules tested for density, melt flow index, and tensile strength.

2

Bi-Axial Rotational Molding

Multi-axis high-temperature rotational molding guarantees uniform wall distribution without weak seams.

3

Co-Extruded Multi-Layer Fusion

Distinct polymer layers (3 to 6 layers) fused molecularly to form an impenetrable, unified tank shell.

4

Quality & Hydrostatic Testing

Every batch undergoes drop impact, hydrostatic pressure, and wall thickness ultrasonic testing before dispatch.

Frequently Asked Questions About Water Tanks

Common questions regarding capacity selection, layer differences, installation, and factory delivery across Bihar.

SR POLYMERS manufactures heavy-duty water storage tanks in capacities ranging from 500 litres to 5000 litres, including 500 Ltr, 750 Ltr, 1000 Ltr, 1500 Ltr, 2000 Ltr, 3000 Ltr, and 5000 Ltr options.

We manufacture water tanks with 3-layer, 4-layer, 5-layer, and 6-layer construction. Each layer serves a dedicated purpose, including UV radiation protection, structural reinforcement, thermal insulation, and hygienic food-grade water contact.

The SR POLYMERS manufacturing facility is located at 6PPP+46H, Jale - Atarwel Path, Mankauli, Maheshpatti, Bihar ? 847104. We supply water storage tanks across districts of Bihar.

Virgin food-grade polymer ensures that stored drinking water does not absorb toxic plasticizers, chemical odors, or harmful leachates. Unlike recycled scrap plastic, certified virgin polymers maintain structural elasticity, resisting cracks and environmental stress.

Multi-layer tanks (especially 4-layer, 5-layer, and 6-layer options) incorporate specialized thermal insulation layers between the outer UV shield and the inner liner. This reduces heat conduction from direct sunlight and helps moderate stored water temperature.

A common guideline is approximately 150 to 200 litres per person per day. For a nuclear family of 3-4 persons, a 500 Ltr or 750 Ltr tank is generally suitable. For standard households of 4-7 persons, a 1000 Ltr tank is recommended. For larger joint families or commercial setups, 1500 Ltr to 5000 Ltr tanks provide secure water backup.

The tank should be placed on a flat, smooth, and rigid concrete surface that fully supports the bottom without overhang. Avoid placing tanks on uneven bricks or narrow iron grates. Ensure flexible pipe connections near the inlet and outlet to prevent stress on the tank fittings.

Sunlight contains ultraviolet (UV) radiation that can break molecular polymer bonds over time, leading to fading, brittleness, and cracking. SR POLYMERS tanks use specialized UV-stabilized outer layers to shield the tank structure from harmful solar exposure.

You can send an enquiry directly through our website contact form by specifying your required capacity (500L to 5000L), layer choice (3 to 6 layers), quantity, and delivery location. Our sales team will get in touch with you.
