Arka Ganga Water Tanks | Built to Last

When choosing a water storage solution, one common question we hear at Arka Ganga is: Are 3-layer tanks better than 2-layer tanks? The answer lies in understanding how each layer functions.

2-layer tanks are typically made of two layers of food-grade plastic, ensuring safe water storage and basic UV protection. They are suitable for moderate climates and general household usage. However, prolonged exposure to sunlight can cause internal water heating and gradual material degradation.

3-layer tanks, on the other hand, offer an added layer of protection and performance. At Arka Ganga, our 3-layer tanks consist of:

1. Outer Layer – UV-resistant material that protects against sunlight and heat.

2. Middle Layer – Insulating barrier that helps regulate water temperature.

3. Inner Layer – 100% food-grade material to ensure hygienic storage of drinking water.

This layered construction enhances durability, insulation, and hygiene, making 3-layer tanks ideal for both residential and commercial use—especially in regions with high temperatures.

From an expertise standpoint, Arka Ganga uses virgin LLDPE material and rotational moulding technology to ensure uniform thickness and long-lasting performance. All our tanks comply with IS 12701 standards, and we offer custom sizes ranging from 500 to 10,000 liters.

Choosing a 3-layer tank is not just about extra layers—it’s about extra protection for your water, your health, and your investment.

Verdict: Yes, 3-layer tanks offer superior benefits over 2-layer models in terms of UV protection, water purity, and structural strength—making them a smarter, safer choice.
