How to Use Less Water at Home in the UAE

Published 22 October 2026 · 5 min read

Simple habits to save water at home in the UAE: find leaks, use less at the tap, water plants wisely and wash your car without a running hose.

In summer, the cold tap in many Dubai homes runs warm for the first minute, and plenty of us just let it flow until it cools. Saving water at home in the UAE comes down to a few simple habits: finding leaks early, using less at taps and in the shower, and watering plants at the right time of day. None of them need a renovation, and each one adds up over a month of bills.

Where does the water in a Dubai home come from?

Most of the water that reaches homes in Dubai is desalinated seawater. DEWA, the Dubai Electricity and Water Authority, produces it at large plants that generate electricity and desalinated water side by side, turning water from the Gulf into drinking water.

That is useful to know, because it means water here is never just water. Every litre that comes out of your tap has already used energy to make, treat and pump it to your building. Using less water at home quietly saves energy too.

It is also a national priority. The UAE Water Security Strategy 2036, from the Ministry of Energy and Infrastructure, aims to reduce total demand for water resources by 21%. Most of that work happens at a large scale, but households are part of it, and the habits below are where you come in.

How do I check my home for hidden leaks?

Leaks are the easiest saving to miss, because you cannot always see them. A slow drip, a toilet that keeps topping up, or a garden line under the soil can run all day without anyone noticing.

The simplest check uses your water meter:

• Turn off every tap, and make sure the washing machine, dishwasher and irrigation are not running.
• Write down the meter reading, or take a photo of it.
• Wait an hour or two without using any water, then check again.

If the number has moved, water is going somewhere. Toilets are a common place to look. Add a few drops of food colouring to the cistern, wait around a quarter of an hour without flushing, and look in the bowl. If colour appears, the flush valve is letting water through, and it is usually a simple part to replace.

In a villa, it is worth checking the water tank too. If the float valve sticks, the tank can overflow quietly through its outlet pipe, often somewhere nobody looks.

Here is something many residents have not noticed: since the March 2025 billing cycle, DEWA measures water in cubic metres instead of imperial gallons. One cubic metre is 1,000 litres, so to picture your use in litres, multiply the figure on your bill by 1,000. Comparing that figure with your previous bills is one of the easiest ways to spot a leak early. A sudden jump with no change in routine is worth a look.

Which everyday habits are worth changing?

Most of the water used indoors goes through bathrooms and kitchens, so these are good places to start. None of the changes below need special skills.

• Fit aerators to your taps and a water-saving shower head. They are inexpensive, screw on in minutes, and mix air into the flow so it still feels full.
• Keep showers short, and turn the tap off while you brush your teeth, shave or wash your face.
• Catch the warm water in summer. Instead of running the cold tap until it cools, fill a jug or bucket and use it for plants or cleaning.
• Run the washing machine and dishwasher only when they are full, and use the eco setting if they have one.
• Scrape plates into the bin rather than rinsing them under a running tap.
• Defrost food in the fridge overnight, not under running water.
• Use the smaller flush on a dual flush toilet when that is all you need.

None of these feel like a sacrifice once they become routine, and that is the point. Habits that are easy to keep are the ones that actually save water over time.

How should I water plants in the Dubai heat?

In a villa with a garden, outdoor watering is often a big part of the water bill, so a few changes here go a long way.

Timing matters most. Water early in the morning or after sunset, when it is cooler and less is lost to evaporation and wind. More of the water given in the midday sun is lost before it reaches the roots.

A few other things help:

• Drip irrigation puts water at the base of each plant instead of spraying paths and walls.
• Adjust irrigation timers with the seasons. Plants need much less in the cooler months than they do in July and August.
• A layer of mulch over the soil keeps moisture in and roots cooler.
• Native and well adapted plants, such as the ghaf tree and many local shrubs and grasses, need far less water once they are established.
• Water collected from your AC unit's condensate line, where you can do so safely, is a handy extra for potted plants.

After any work in the garden, walk round and check the sprinkler heads. A head that has been knocked sideways can water a wall for weeks before anyone notices.

Is there a water-wise way to wash a car at home?

If you wash your car at home, the biggest saving is simple: do not leave the hose running. A bucket and a soft wash mitt use much less water, and you stay in control of every drop.

Start by blowing off the loose dust with an air blower, or giving the car a brief, gentle rinse, before anything touches the paint. Dubai dust is fine and gritty, and wiping it off dry drags it across the clear coat. After that, wash one section at a time from the roof down, rinse your mitt often in a second bucket, and dry with clean microfibre towels.

Wash in the shade or early in the day. In the heat, water and soap dry on the paint before you can wipe them, which leaves spots and tempts you to use more water to fix them. Where you can, keep the soapy water on your own driveway rather than letting it run into the street.

If you only do three things

• Do the meter test once, and fix any leak you find.
• Fit tap aerators and keep showers short.
• Water the garden early or late, and only as much as the season needs.
