Vertical or Horizontal? Which Water Tank is Right for Your Saudi Home?

Water tanks are a fundamental part of every household in Saudi Arabia. However, when it's time to buy or replace one, many homeowners find themselves at a crossroads: Should I choose a vertical or a horizontal tank? And what makes top brands like Al-Zamil or Al-Muhaidib stand out?

In this comprehensive guide, we’ll break down the key differences to help you make an informed decision that ensures water sustainability and purity for your family.


1. Vertical Water Tanks (Space Savers)

Vertical tanks are characterized by their height and a design that occupies a very small horizontal footprint.

  • Best Use: Ideal for narrow spaces, side setbacks, or corners in villas and residential buildings.
  • Capacity: They often come in massive sizes, sometimes exceeding 20,000 liters, making them the primary choice for large projects and apartment complexes.
  • Pros: Easier access for cleaning and maintenance due to their upright design.


2. Horizontal Water Tanks (Stability Masters)

These tanks are designed to be low-profile and extend horizontally.

  • Best Use: Most commonly used on rooftops. Because they distribute weight over a larger area, they offer superior stability against high winds and vibrations.
  • Capacity: Usually ranges from 500 liters to 5,000 liters.
  • Pros: Their sleek, low profile makes them less visible on the roof, preserving the architectural aesthetic of your home.


At Sawab, we provide top-tier brands like Al-Zamil and Al-Muhaidib, which utilize advanced manufacturing technologies:

  1. High-Density Polyethylene (HDPE): A robust, impact-resistant material that does not react with water, ensuring it remains safe for drinking.
  2. 4-Layer Technology: * Outer Layer: White to reflect harsh Saudi sunlight and reduce heat absorption.
  • Anti-UV Layer: Prevents sunlight penetration, which completely stops algae growth.
  • Inner Layer: Ultra-smooth to prevent the buildup of salts, sediment, and bacteria.


Sawab Expert Tip: When choosing a tank, look for a long-term warranty (up to 10 years for brands like Al-Zamil). This reflects the manufacturer’s confidence in the quality of the materials used.


How to Choose the Right Capacity?

To calculate the capacity your household needs, use this simple formula:

  • The average water consumption per person in Saudi Arabia is approximately 250–300 liters per day.
  • If you have a family of 5, you need a tank with a capacity of at least 1,500 liters to secure a full day’s supply in case of a main source interruption.
