When selecting the best water tank size for a home, several factors must be considered, including household size, daily water consumption, climate, and intended usage. A properly sized water tank ensures a reliable supply for daily needs while optimizing efficiency and cost. Among the various options available, GRP (Glass Reinforced Plastic) water tanks stand out as a durable and efficient solution for residential water storage.
The number of residents in a home significantly affects the required water storage capacity. Below is a guideline for determining an appropriate tank size:
| Household Size | Recommended Tank Size |
|---|---|
| 1-2 people | 500 - 1,000 liters |
| 3-4 people | 1,500 - 3,000 liters |
| 5-6 people | 3,000 - 5,000 liters |
| 7+ people | 5,000+ liters |
On average, a person uses 150-250 liters of water per day, depending on activities such as drinking, cooking, cleaning, and bathing. Homes with gardens, swimming pools, or irrigation systems may require larger tanks.
If your home relies on municipal water with frequent supply, a smaller tank may be sufficient. However, in areas with irregular water supply or reliance on rainwater harvesting, a larger water tank is recommended to ensure an uninterrupted water supply.
In regions with seasonal rainfall, a rainwater harvesting system with a large GRP water tank can help reduce dependence on municipal water. The storage capacity should be large enough to capture and retain sufficient rainwater during wet seasons for use in dry months.
If water is only for drinking and household chores, a moderate-sized tank will suffice. However, for gardening, car washing, or livestock, a higher capacity GRP water tank is advisable.
GRP (Glass Reinforced Plastic) water tanks offer numerous advantages over traditional steel or plastic tanks. Here’s why they are an ideal choice for home water storage:
GRP water tanks are highly resistant to corrosion, UV radiation, and harsh weather conditions, ensuring a lifespan of over 20 years with minimal maintenance.
The non-toxic, non-corrosive inner surface of GRP tanks prevents bacterial growth, making them safe for storing potable water. Unlike metal tanks, they do not rust or leach harmful substances into the water.
GRP water tanks are available in modular designs, allowing homeowners to customize the size and shape based on available space. They can be installed above ground, underground, or on rooftops for maximum convenience.
Despite being lightweight, GRP tanks are exceptionally strong and capable of withstanding high pressure, making them ideal for various residential applications.
| Household Usage | Suggested GRP Tank Size |
|---|---|
| Drinking & Cooking Only | 500 - 1,000 liters |
| General Household Use | 2,000 - 3,000 liters |
| Large Family with Garden | 5,000 liters or more |
| Rainwater Harvesting System | 10,000+ liters |
Choosing the right water tank size depends on your household’s daily consumption, climate conditions, and intended water use. GRP water tanks provide a durable, hygienic, and cost-effective solution for residential water storage. By selecting the right capacity and integrating rainwater harvesting, homeowners can ensure a sustainable and reliable water supply year-round.
