Layer-by-Layer Engineering for 5000L

Every layer serves a dedicated functional purpose to keep water clean, cool, and structurally contained.

Layer 1: External Weather & UV Shield Sun Protection

Engineered with concentrated UV stabilizers to deflect harsh solar ultraviolet rays, preventing polymer degradation, surface cracking, and color fading under open skies.

Layer 2: Carbon Black Light Barrier Anti-Algae

100% light-blocking barrier that stops sunlight from penetrating the water inside the tank, effectively halting photosynthesis and preventing algae, slime, and green bacteria development.

Layer 3: Thermal Insulation Foam (4L, 5L, 6L) Temperature Control

Expanded micro-cellular foam core acts as a high-efficiency thermal resistor, keeping water substantially cooler during extreme summer heatwaves and preventing extreme chilling during winters.

Layer 4 & 5: Structural Core & Anti-Microbial Barrier Mechanical Strength

High-density virgin polymer matrix providing tensile hoop strength against hydrostatic water volume, reinforced with antibacterial additives to maintain pure drinking water hygiene.

Layer 6: Mirror-Smooth Food-Grade Inner Core 100% Pure Drinking Water

100% FDA-compliant virgin polymer inner wall with a glass-smooth finish that leaves water completely odorless, tasteless, and safe for drinking and cooking.

Frequently Asked Questions: 5000L Tank

Technical questions regarding capacity, layer selection, installation, and delivery across Bihar.

The SR POLYMERS 5000 Ltr tank has a nominal holding capacity of 5000 litres (~1320 Gallons). It is precision engineered with rotational molding to ensure true volumetric holding without bulging under full hydrostatic pressure.

For standard rooftop installations with moderate sun exposure, our 3 Layer model provides excellent UV shielding and food-grade purity. For high-heat rooftop environments where keeping water cool during peak Bihar summers is essential, we strongly recommend our 4 Layer (Foam Insulated) or 5/6 Layer Heavy Duty configurations.

A 5000 Ltr tank filled with water weighs approximately 5040 kg. It must be installed on a flat, clean, level concrete surface or engineered steel platform with complete surface contact across the entire bottom base. Ensure there are no sharp stones or debris under the base.

Yes, our factory at Mankauli, Maheshpatti, Bihar (6PPP+46H, Jale - Atarwel Path) provides direct dispatch and transport across Darbhanga, Madhubani, Samastipur, Muzaffarpur, Sitamarhi, Patna, and all surrounding districts.

Thanks to our mirror-smooth virgin food-grade inner lining, sediment adheres minimally. We recommend an annual or bi-annual inspection and light water-jet rinse through the 500 mm (approx 19.7 in) manhole opening. Never use harsh metal scouring pads or toxic solvent chemicals.

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.
