150 USG (568 L)
Vertical Plastic Water Tank

The 150 USG vertical water tank holds about 568 litres and measures roughly 92 cm across and 93 cm high. It is the tank most people mean when they search for a "500 litre water tank" in the UAE, and it is one of the smallest sizes that still gives a household a useful reserve. This guide explains who the 150 gallon tank suits, how to judge whether 568 litres is enough, and how to install and look after it in UAE conditions.

Who Should Buy a 150 USG Vertical Tank?

A 568 litre tank is a small-scale storage solution. It works best where the water supply is reliable and you need a buffer, rather than days of independent supply. Typical uses in the UAE include:

• Apartment balconies, utility rooms and service areas with limited floor space.
• Small villas, annexes, majlis blocks and staff rooms that need a dedicated supply.
• Garden and outdoor kitchen supply, where the tank feeds taps or a small pump.
• Small shops, workshops, salons and offices with modest daily demand.
• Back-up storage for a larger property when mains water is interrupted for a few hours.

If you need a tank for a whole villa with several bedrooms, a larger size is a better fit. See the full range of PVC plastic tanks or use the water tank size calculator to match a size to your household.

Is 568 Litres Enough?

Usage varies widely, so treat any figure as a starting point. As a rough guide, a 568 litre tank gives a small household a reserve of roughly one day for drinking, cooking and basic washing, and less if the tank also feeds showers, washing machines or garden taps. Heavy users, such as larger families or businesses with constant demand, will use it up much faster.

The simplest way to size is to estimate daily use and decide how many days of reserve you want. If your supply rarely fails and you only want a short buffer, 150 gallons can be enough. If outages are common or the tank is your only source, step up to 250, 500 or 1,000 gallons. The size neighbours of the 150 USG tank are the 100 USG (about 379 litres) and 200 USG (about 757 litres) models, so you can scale up or down in small steps.

Why a Vertical Tank?

A vertical tank uses a small, round footprint and stores water in height. The 150 USG model needs a base not much wider than 92 cm, which makes it easy to fit beside a wall, on a roof slab or on a balcony. The ribbed side wall stiffens the cylinder and helps it keep its shape when full, and the wide opening at the top allows the inside to be inspected and cleaned. The diagram on this page shows the top, side and 3D views with the key dimensions.

Materials and Build

The tank is made of UV-stabilised polyethylene, a food-grade material suitable for storing potable water. Polyethylene does not rust, does not need painting and is not affected by the salts and minerals found in UAE water. UV stabilisation matters here, because strong sun is the biggest long-term stress on any plastic tank outdoors. The tank is covered by a 5-year warranty.

Weight and Base Requirements

Water weighs about one kilogram per litre, so a full 150 USG tank carries around 568 kg of water on top of the weight of the tank itself. That load needs a proper base:

• Use a flat, level concrete slab or a solid, evenly supported surface that covers the whole footprint.
• On a roof or balcony, confirm that the structure can carry the full load of the filled tank.
• Remove stones and sharp debris before positioning the tank.
• Leave space around the tank so fittings can be reached and the tank can be cleaned.

Installing the Tank in UAE Conditions

Installation is straightforward, but a few points matter in the UAE climate. Shade the tank where you can. A tank in full summer sun heats its contents, and warm water supports faster algae and bacterial growth. A simple shade or an enclosure keeps temperatures down and extends the life of the plastic. Fit an overflow pipe that drains safely away, use a float valve on the inlet so the tank cannot over-fill, and keep an isolation valve on the outlet so the tank can be shut off for maintenance. Use flexible connectors at the tank and support the pipes separately, so the tank wall is not carrying the weight of the pipework.

Before using the water for drinking, wash the inside and disinfect the tank. Our guide to tank cleaning and maintenance explains the process, and we also offer professional water tank cleaning in Dubai.

Looking After a 150 USG Tank

• Keep the lid closed and in good condition to keep out dust, insects and light.
• Clean and disinfect at least once or twice a year, and more often if the water tastes or smells different.
• Check the float valve, overflow and fittings regularly for leaks.
• Avoid dragging the tank, and do not store sharp objects against it.
• Do not pour hot or boiling water into the tank.
