The Ultimate Guide to Choosing an Overhead Water Tank for Your Home

Introduction

Safe drinking water is a basic necessity, and a continuous water supply is essential for day-to-day activities. However, municipalities often fail to provide adequate water throughout the day. As a result, homeowners prefer to invest in an overhead water tank to ensure a constant water supply. This comprehensive guide will help you understand the purpose, types, and best practices for choosing and maintaining an overhead water tank for your home.

Purpose of an Overhead Water Tank

Water Storage and Accessibility

An overhead water tank collects and stores water for later use, ensuring that you have access to water 24/7. These tanks are particularly useful in areas where municipal water supply is inconsistent. They can also serve as catchment tanks for rainwater, contributing to water conservation efforts.

Materials Used in Water Tanks

In India, water tanks are made from various materials, including plastic, concrete, metal, fiberglass, and steel. Among these, plastic polyethylene (poly) water tanks are the most popular due to their lightweight, non-corrosive, and leak-proof nature. These tanks can last up to 10 years or more, depending on the material used.

Types of Water Tanks

There are also overhead and underground water tanks designed for storing rainwater and municipal water.

How to Choose the Best Water Tank in India

Factors to Consider

When buying a water storage tank for your home, several factors need to be considered:

  • Capacity: The size of the tank should match your household’s water consumption needs.
  • Material: Choose a durable and safe material.
  • Shape: The shape should fit the available space.
  • Color: Some colors are better at preventing UV rays and bacterial growth.

Determining the Right Capacity

The capacity of the water tank should be based on the size of your family:

  • For a small family, a 500 to 600-liter tank is sufficient.
  • For a larger family, opt for a 700 to 1,000-liter tank.
  • Smaller tanks with capacities ranging from 100 to 300 liters are also available for specific needs.

Water Storage Tanks: Shape

Choosing the Right Shape

Water storage tanks come in various shapes, and the choice should depend on the available space:

  • Vertical Tanks: Ideal for groundwater storage.

  • Cylindrical Tanks: Best for large areas and provide uniform stress distribution.

Storage tanks are available in various colors such as black, white, green, and beige. Black and green tanks are preferred as they prevent ultraviolet rays and the growth of harmful bacteria.

Vastu for Underground Tank

Underground water tanks should be placed towards the north or east. The north-east direction is particularly auspicious, bringing happiness, wealth, and prosperity. Avoid placing underground tanks in the south, south-east, north-west, or south-west directions.
