Kerala’s climate and water storage challenges

Kerala experiences three seasons, summer, monsoon, and winter. Summer is from March to May, while the winter season is from November through February. The state receives rainfall twice a year during its monsoon seasons, which creates unique water storage challenges in Kerala for households using water tanks in Kerala. The Southwest monsoon, occurring from June to August, is the primary rainy season, followed by the Northeast monsoon around October to November.
Key Water Storage Challenges in Kerala’s Climate:
1. Heavy Rainfall & High Humidity
- Continuous rain and humidity can weaken poor-quality water tanks over time.
- Metal tanks may corrode, and low-grade plastic tanks can crack or deform.
- Moist conditions encourage fungus, algae, and bacterial growth inside tanks if materials are not hygienic, making algae free water tanks essential.
2. Water Contamination Risks
- Rainwater runoff, dust, and organic matter can enter tanks if lids are loose or poorly designed.
- Birds, insects, rodents, and even strong winds can displace weak lids, leading to contamination.
- Open or damaged tanks increase the risk of waterborne diseases during monsoon months.
3. Structural Stress from Wind & Water Pressure
- Tanks placed on rooftops face strong winds and constant water pressure.
- Inferior tanks may leak, warp, or develop micro-cracks, leading to water loss and structural damage to buildings, highlighting the need for the best water tank for Kerala climate.
4. Summer Water Scarcity
- During summer, many households rely on water tankers or stored water due to reduced groundwater levels.
- This makes having adequate storage capacity essential for daily needs like drinking, cooking, and bathing.
5. Chemical Leaching Due to Heat Exposure
- Low-grade plastic water tanks may release harmful substances into water when exposed to heat.
6. UV Exposure & Algae Formation
- Direct sunlight and UV rays can penetrate low-grade tanks.
- This leads to algae growth, bad odor, discoloration, and frequent cleaning requirements.
- Heat can also weaken ordinary plastic, shortening the tank’s lifespan.
What Households Need in Kerala’s Climate
To withstand Kerala’s seasonal extremes, water tanks must offer:
- High durability and flexibility to handle pressure and climate changes
- UV protection to prevent algae formation using UV protected water tanks
- Hygienic, food-grade material with no cancer-causing substances
- Secure lids to protect water from external contamination
- Long life with minimal maintenance
This naturally leads into why Sintex water tanks are designed perfectly for Kerala homes.
Why Sintex Water Tanks Perform Better in Humid and Rainy Conditions
Sintex water tanks are manufactured using advanced computerized design and the roto-moulding process, Sintex tanks offer uniform thickness and excellent structural strength. The multi-ribbed design enhances durability and allows the tank to withstand high humidity, heavy rainfall, and continuous water pressure. Being rust-proof and leak-proof, they perform reliably during Kerala’s monsoon seasons.
Sintex water tanks are 100% UV stabilized, preventing sunlight from reaching the stored water and eliminating algae formation, making them reliable UV protected water tanks. This helps maintain water freshness, color, and odor even under prolonged heat exposure. The double-layer construction also improves UV protection and allows easy monitoring of water levels.
A tightly sealed threaded lid prevents birds, animals, insects, and strong winds from opening the tank, ensuring water safety and hygiene. The lightweight yet sturdy design makes transportation and installation easy. Durable and economical, Sintex water tanks provide a long-lasting water storage solution and are widely regarded as the best water tank for Kerala climate.
