Reasons to Buy Astral Water Tanks This Summer

Every summer in India, the heat does more than just drain your energy. It quietly works on your overhead water tank too, warming the stored water, encouraging algae, weakening ordinary plastic, and raising genuine questions about what is coming out of your taps. If you have ever opened a tap in May and wondered about the water quality, you are not alone. Choosing the right water tank for summer is one of those decisions that seems minor until it is not. Astral water tanks, and specifically the Astral Cleo 4-Layer Water Tank, are built with exactly these summer challenges in mind. Here is why they stand out.

Why Should You Choose the Right Water Tank for Summer?

India’s summers are intense. In many parts of the country, rooftop temperatures cross 50°C, and tanks placed outdoors take the full brunt of that heat. Degraded plastic, inadequate UV shielding, and no microbial control are common problems that go unnoticed until water quality suffers. Selecting a tank designed for Indian summers means your stored water stays cleaner, cooler and safer for everyday use.

Challenges of Using Ordinary Water Tanks in Summer

Ordinary water tanks were not engineered for the specific demands of an Indian summer. These are the most common problems homeowners face:

1. Water Heating Due to Direct Sunlight

Single or dual-layer tanks absorb heat from sunlight and pass it into the stored water. Warm water in a tank is not just uncomfortable to use, it creates the right conditions for microbial growth and faster plastic degradation.

2. Algae and Bacterial Growth

Sunlight penetrating through thin, light-coloured tank walls triggers algae growth. Combined with higher water temperatures, bacteria and other microbes multiply faster, compromising the hygiene of stored water.

3. Plastic Degradation and Cracking

Prolonged UV exposure breaks down the polymer chains in ordinary plastic tanks. Over time, this leads to chalking, micro-cracks and loss of structural strength, problems that show up in the form of leaks or complete tank failure.

4. Water Quality Issues

All of the above combine to affect the taste, smell and safety of stored water. In a country where many households depend on overhead tanks as their primary water source, this is a serious concern.

Reasons to Buy Astral Water Tanks This Summer

The Astral Cleo 4-Layer Water Tank is purpose-built for Indian conditions. Here are the key reasons it makes a strong case as the best water tank for summer use:

1. Advanced UV Protection

The outer layer of the Astral Cleo tank is made with the highest quality UV-stabilised material. It is designed to resist harsh UV rays, reduce overall heat absorption from sunlight and prevent the breakdown of polymer chains that lead to cracking. This directly protects the structural life of the tank and keeps water temperatures lower even under extreme weather.

2. Heat-Resistant Multi-Layer Technology

The Astral Cleo tank features four distinct layers, each serving a purpose:

  • Layer 1 (Outer): UV-stabilised, available in White, Blue, Yellow or Green
  • Layer 2 (Black middle): Blocks sunlight from penetrating the tank wall, preventing microbial activity
  • Layer 3 (Grey middle): Maintains lower water temperature and provides structural support
  • Layer 4 (Inner – Anti-Viral Copper Shield): Food-grade material with active copper fortification

Together, these four layers make the Astral Cleo tank among the most advanced water tanks in India for summer performance.

3. India’s 1st Anti-Viral Copper Shield

This is what truly sets Astral Cleo apart. The innermost layer is embedded with active copper particles, a world-class innovation that makes this India’s first water tank with an Anti-Viral Copper Shield. Active copper is impregnated within the polymer so it does not leach beyond safe limits, yet the anti-viral and anti-microbial protection remains active throughout the tank’s life.

4. Food-Grade and Safe Material

The inner layer of the Astral Cleo water tank is made from 100% food-grade raw material, as it comes directly in contact with water. The Cleo tank is NSF certified, which is an internationally recognised standard for water contact safety.

5. High Durability and Structural Strength

The tank is built stronger with added ribs that enhance durability and reduce bulging when the tank is full. This lowers the risk of bursting under pressure, which is a genuine concern with cheaper tanks installed at height.

6. Hygienic Design with Threaded Lid

The threaded lid keeps dust and external contaminants out of the tank. It also includes an inner lid that provides a barrier against direct sunlight, keeping water safe and algae-free. The air ventilation feature allows water to maintain a natural oxygen level, keeping it fresh and helping avoid deformations.

7. Available in Multiple Sizes and Colours

Astral water tanks are available in capacities ranging from 500 litres to 10,000 litres, making them suitable for everything from small apartments to large homes and commercial properties. Colour options include White, Blue, Yellow and Green, so you can match the tank to your building aesthetics.

Astral Water Tanks vs Regular Water Tanks

Here is a quick look at how Astral Cleo water tanks compare with ordinary water tanks on the features that matter most in summer:

Feature

Astral Cleo Water Tank

Ordinary Water Tank

UV Protection 4-layer UV stabilised outer wall Single or dual layer, limited UV resistance
Anti-Viral Technology Anti-Viral Copper Shield 

(India’s 1st)

Not available
Material Safety 100% food-grade, NSF certified Varies; often unverified
Microbial Protection Protection from bacteria, algae, fungus, virus No active protection
Structural Strength Built Stronger with added ribs Standard build, higher risk of bulging
Lid Design Threaded lid with inner lid protection Basic lid; no inner sunlight barrier
Available Sizes 500 L to 10,000 L Limited range
Colour Options White, Blue, Yellow, Green Usually white or blue only

The differences are significant, especially in a country where summers last five to six months and water storage directly affects daily health.

FAQ's

The Astral Cleo 4-Layer Water Tank is one of the best water tanks for summer in India. Its UV-stabilised outer layer, heat-resistant multi-layer construction and Anti-Viral Copper Shield work together to keep stored water cooler, cleaner and protected from microbial growth, even during peak summer months. It is available in sizes from 500 litres to 10,000 litres.

Algae grow when sunlight reaches the water inside a tank. Astral water tanks use a black middle layer that blocks sunlight from penetrating the tank wall. The Anti-Viral Copper Shield in the innermost layer adds another line of defence by actively inhibiting algae, bacteria, fungi and viruses.

A 1,000-litre water tank is generally recommended for a family of four in India for daily domestic use. Larger families or homes in areas with an irregular water supply may prefer 1,500 to 2,000 litres. Astral water tanks are available in seven sizes from 500 litres to 10,000 litres, giving you the flexibility to choose based on your household needs.

Yes. The inner layer of Astral Cleo water tanks is made from 100% food-grade raw material and the product is NSF certified, an internationally recognised water safety standard. The Anti-Viral Copper Shield in the inner layer actively neutralises harmful microbes. The water stored in Astral water tanks is safe for drinking and everyday domestic use.
