FEWA Bill Check — High Water Bill in UAE? Complete Guide to Finding the Cause

Received a FEWA notification about unusually high water consumption? Or opened your SEWA or EtihadWE account to find your bill doubled or tripled without any obvious reason? You're not alone — and in most cases, the answer isn't that your family suddenly started using more water. The most common culprit is a hidden water leak somewhere in your property's plumbing network.

This guide walks you through exactly how to check your water bill, what the numbers mean, and — most importantly — how to find and fix the problem before it costs you more.

Understanding Your UAE Water Bill

Before we talk about leaks, let's make sure you're reading your bill correctly.

FEWA (Federal Electricity & Water Authority)

FEWA serves residents of the Northern Emirates — Ras Al Khaimah, Fujairah, Umm Al Quwain, Ajman (partially), and parts of Sharjah. Your FEWA bill shows:

• Current reading: The meter reading at the end of this billing period
• Previous reading: The meter reading at the start of this billing period
• Consumption: The difference — your actual water usage in Imperial Gallons or cubic meters
• Amount due: Calculated based on consumption tiers

Normal consumption reference: A typical household of 4-5 people in the UAE uses approximately 800–1,500 Imperial Gallons (3,600–6,800 liters) per month. If your FEWA bill shows significantly higher consumption with no lifestyle change, investigate immediately.

SEWA (Sharjah Electricity and Water Authority)

SEWA serves Sharjah residents. The bill structure is similar to FEWA. You can check your consumption history through the SEWA smart app or website — compare the same month last year, not just the previous month, since summer naturally increases usage.

EtihadWE (Emirates Water and Electricity Company)

EtihadWE serves Abu Dhabi, Al Ain, and the Western Region. The ADDC (Abu Dhabi Distribution Company) model applies here. Monthly statements are accessible through the EtihadWE app, which also shows a consumption graph across months — one of the most useful features for spotting anomalies.

How to Check If Your Bill Is Abnormally High

Step 1: Compare Year-Over-Year, Not Month-to-Month

Don't compare July 2026 to June 2026. Compare July 2026 to July 2025. Why? Because summer in the UAE means higher consumption due to air conditioning, swimming pools, and increased irrigation. A 20–30% seasonal variation is normal. A 60–100% jump compared to the same period last year is not.

Step 2: Check Your Consumption Trend

Log into your FEWA, SEWA, or EtihadWE account and view your consumption history graph. A sudden spike in one month — while all surrounding months are normal — is the clearest indicator that something changed, not your lifestyle.

Step 3: Calculate Your Daily Usage

Divide your monthly consumption by 30 to get your daily average. If a 4-person household is consuming more than 400 gallons (1,800 liters) per day consistently, there's likely a leak.

The Water Meter Test — 15 Minutes to Confirm a Leak

This is the most reliable test you can do yourself, for free, right now. It's the same test our technicians perform first at every inspection.

What you need: Nothing. Just access to your water meter.

Steps:

1. Turn off everything that uses water in your property — all taps, washing machines, dishwashers, water heaters, garden irrigation systems. Make sure nobody uses any water during the test.
2. Locate your water meter. For villas, it's usually near the entrance gate or at the property boundary. For apartments, it may be in a utility cupboard or near the main door.
3. Take a photo of the current reading with your phone. Make sure to capture the small rotating dial or the decimal digits — these are the most sensitive indicators.
4. Wait 15 minutes without using any water at all.
5. Return and compare:
   • If the meter hasn't moved at all → Your internal plumbing is likely fine
   • If the meter moved, even slightly → You have an active leak somewhere in your property

For slow leaks: Run the same test overnight — take a photo before bed and another immediately after waking up (8 hours). Any difference = confirmed leak.

What the Meter Test Tells You — and What It Doesn't

The meter test confirms that there is a leak. It doesn't tell you where the leak is. And that's where most people make an expensive mistake: they start breaking walls or digging up gardens randomly, only to find the leak is somewhere completely different.

The meter test result combined with a few simple observations can help narrow down the location:

If the Meter Stops When You Close the Garden Irrigation Valve

The leak is in your irrigation network. Underground irrigation pipes in UAE villas are a very common source — the sandy soil absorbs leaking water instantly, leaving no visible trace above ground.

If the Meter Continues Running Even After Closing the Garden Valve

The leak is inside the building — in feed pipes behind walls, under floors, in bathrooms or the kitchen.

If You Hear Running Water with All Taps Closed

Listen carefully near your bathroom walls late at night when the house is quiet. A faint sound of running or dripping water — when everything is shut — means water is moving through pressurized pipes that should be static. This is a strong indicator of a supply line leak behind a wall.

Common Sources of Leaks in UAE Properties

Villas

Underground irrigation lines are the most common culprit in villas across Dubai, Abu Dhabi, Sharjah, and the Northern Emirates. These plastic or metal pipes, buried beneath your garden and driveway, are exposed to the UAE's extreme heat — the ground surface can reach 70°C in summer — causing expansion, contraction, and eventual joint failure. The leak flows directly into the sandy soil with zero visible indication.

Underground water tanks in many UAE villas develop hairline cracks from years of thermal stress. A 10,000-liter tank with a small crack can lose hundreds of liters daily, silently.

Main supply line from the FEWA/SEWA/EtihadWE meter to the building — this buried line can develop joint failures, especially in older properties where galvanized steel pipes have exceeded their lifespan.

Apartments and High-Rise Buildings

Behind-wall pipe connections in bathrooms and kitchens are the most frequent source. A slow-leaking joint behind tiles can saturate the concrete and cause mold, rising damp, and structural staining — often appearing on the ceiling of the apartment below before the leak source is detected.

Toilet flushing mechanisms are a surprisingly common source of silent waste. A faulty float valve can allow water to continuously flow into the bowl. Test yours: add a few drops of food coloring to the toilet cistern (tank). If the color appears in the bowl within 15 minutes without flushing — your toilet valve is leaking.

Rooftop water tanks in apartment buildings are exposed to direct sunlight and extreme temperature cycling. Plastic tanks crack; iron tanks rust. A leaking rooftop tank often goes unnoticed until the pump begins running more frequently than normal.

Swimming Pools

Villas with private pools in communities like Emirates Hills, Arabian Ranches, The Springs, and Jumeirah experience pool leaks more often than most owners realize. Natural evaporation in the UAE summer accounts for roughly 1–2 inches of water loss per week. Anything beyond that needs investigation.

The bucket test for pools:

1. Fill a bucket with pool water to 5cm from the top
2. Place it on a pool step so its water level matches the pool's water level
3. Mark the water level in both the bucket and the pool
4. Wait 24 hours (don't use the pool)
5. If the pool dropped more than the bucket → You have a pool leak

Why Electronic Detection — Not Breaking Walls

Once the meter test confirms a leak, the traditional approach was to break open walls and floors systematically until the leak was found. This is expensive, messy, and often wrong — the leak might be on the other side of the building entirely.

Modern electronic detection uses two instruments:

Acoustic leak detector: The pressurized water escaping through a crack creates vibrations — too subtle for human hearing, but detectable by a sensitive acoustic sensor placed against walls, floors, and ground surfaces. The technician systematically maps the vibration intensity to pinpoint the exact location.

Thermal imaging camera: Water absorbs and retains heat differently than dry building materials. A thermal camera detects the temperature difference between wet and dry areas — even through several centimeters of tile and concrete — producing a visual map of moisture distribution before any surface is broken.

Together, these two instruments locate the leak to within 20cm accuracy in most cases. The opening in your wall or floor is minimal — a single access point, not a demolition project. See our water leak detection service for more details.

Can a High FEWA Bill Be Refunded After a Leak Repair?

This is one of the most common questions we receive. The honest answer: it depends, and it requires documentation.

FEWA, SEWA, and EtihadWE each have processes for reviewing bills following confirmed leaks. The standard requirement is a technical report from a qualified inspection service, documenting:

• The location of the leak
• The likely duration (based on the meter readings and consumption pattern)
• The repair method and date

Some customers have successfully had high bills adjusted after presenting such documentation. Others have not. The outcome depends on the utility authority's internal policies and the specific circumstances. What's certain is that without a documented technical report, there is no basis for any request — and Kashef provides this report as part of every inspection.

How Long Does It Take?

A standard leak inspection for a villa in Dubai, Abu Dhabi, or Sharjah takes 2 to 4 hours. An apartment inspection typically takes 45 minutes to 90 minutes. Most straightforward repairs — a joint replacement, a section of pipe — are completed the same day.

The only exceptions requiring longer timelines are bathroom floor waterproofing (requires tile removal and curing time) and full pipe section replacements (which may involve multiple access points).

Frequently Asked Questions

My FEWA bill is high but I can't see any visible leak. Is this possible?

Yes — and it's the most common scenario. Underground irrigation pipe leaks and underground tank leaks leave no visible trace above ground in UAE's sandy soil. The meter test will confirm the leak is there; electronic detection will find where.

Can I do the meter test while the irrigation timer is running?

No. You must shut off all water-consuming systems, including the irrigation control unit, before running the test. If you're unsure how to disable the timer, turn off the irrigation at the main valve instead.

My neighbor has the same problem — is it a FEWA/SEWA network issue?

If your individual meter moved during the 15-minute test, the leak is in your property, not the main network. Neighboring properties having similar issues simply means similar plumbing ages or similar conditions — each meter measures one property's consumption independently.

Does Kashef work in free zones and commercial properties?

Yes. We serve residential villas, apartments, commercial offices, warehouses, hotels, and industrial facilities across all UAE emirates.

Is the inspection cost deducted from the repair cost?

In most cases, yes — when the repair is carried out by Kashef, the inspection fee is offset against the repair invoice. We confirm this arrangement before starting any work.
