Why Is My Water Bill So High? 7 Unexpected Reasons

Why Is My Water Bill So High? My water bill has been skyrocketing over the past few months. I wanted to find out the issues causing that situation.

Why Is My Water Bill So High

So I found out that the main causes for the high water bill are leaks in my plumbing systems. Unfixed plumbing leaks can waste thousands of gallons of water. Further, changes in the way you normally use water can also cause a high water bill. Another reason could be running water from the toilet. Toilet leaks can waste over 200 gallons of water per day.

Let’s Dig Deeper As To Why Is My Water Bill So High?

Most people at one point have received a shockingly high water bill. Getting a high water bill is a worrying issue because of the high financial implications and high levels of water wastage. The EPA reports that average household leaks account for about 10,000 gallons of waste water per year. Further, 10% of households leak over 90 gallons of water each day.

Therefore, when you notice a higher water bill than usual, it’s crucial that you investigate the cause and take action.

So, What are the Causes of a High Water Bill?

Running Water from the Toilet

A toilet that runs continuously after flushing can cause the water bill to skyrocket. Such a running toilet can waste about 200 gallons of water per day. As a result, you’ll notice a huge increase in the water bill. Call an expert and let them fix the issue.

Recent Changes in Your Water Use

A slight change in your household’s water usage routine can have a big impact on the overall water bill. Likely reasons that might bring changes in your water usage pattern include: guests, watering the lawn/garden more than usual and generally things that you don’t normally do, that involve use of water

Increased Watering During Summer

You’ll notice that during summer compared to winter, watering time is likely to increase. On hot days, water evaporation rate raises, so water is used more to keep plants hydrated. Consider using automated irrigation system with timers and program the system accordingly to prevent water wastage that can lead to high bills.

Changes in Water Pricing

Water utility rates are normally determined by the utility bylaws of a specific region. Has there been a recent increase in price per unit of water? Check the yearly rate and total number of days you’re billed. Is it 30 days or 31 days?

Also check if the service charge has been added to the bill.  Another thing you should know is how the billing process happens. Some household play a flat rate while others have a water meter that shows how much they’ve used their water


Unfixed leaks in your water system can cause high water wastage. Ensure you routinely inspect the plumbing system as well as leaky toilets, faucets, or irrigation lines. Underground leaks can occur without your knowledge, wet spots in your garden may indicate a leak. Call an expert to have the entire water system checked.

Leaky fixtures or faucets are also common causes of an increase in water bills. The bigger the leak, the higher the amount of wasted water that eventually results to higher bill.  A leaking faucet is easy to see and fix immediately. Ensure you thoroughly check your shower heads, faucets, outdoor taps, and other water appliances in your home and take necessary action if you notice any leaks.

Outdated or Old Fixtures and Toilets

Old or outdated water systems will use more water than the newly developed water saving fixtures. Most homes that were built some years back have outdated plumbing equipment.  Currently, we’ve seen major innovations and improvements on produced water fixtures like water saving toilets, faucet aerators, and efficient shower heads that save water.

If you’re buying a new home, Inspect the plumbing system, check the toilet, faucet, and shower heads plus anything else that uses water. Check their manufacturing date or ask a professional about the status of the plumbing system.

Water Consuming Equipment

Water consuming equipment like pools, washing machines, sprinklers, and many others can cause a higher water bill.

When buying these equipment ensure the user manual confirms that they are water saving and are marked as high-efficiency. Cover your pool when not in use to avoid evaporation so that the next time you’re filling it takes up less water.

Can A Water Heater Cause A High Water Bill?

Yes! A water heater can cause a high water bill. Leaks from the heater’s tank can cause higher water usage which eventually lead to high water bill. So, how will you know your heater is leaking? You’ll notice dampness, mold and mildew growth, excess condensation, and water stagnating under the heater

Can a Water Softener Increase your Water Bill?

People who own water softeners will have a higher water bill because of the backwash or regeneration cycles that these units normally undergo.

However, your water hardness level will determine the amount of fresh water you use during the regeneration process. Hence, the harder the water, the more often it will regenerate, which in turn will cause an increase in your bill.

Water softeners will regenerate using fresh water on a set schedule. The backwash valve may not operate well causing water wastage that goes into the sewer.

Most times, this wasteful situation may go undetected for a period due to lack of visible proof of water wastage. However, if you take a closer look at your unit, you may spot some water trickling into the sewer pipe. So conduct regular inspection of your unit to avoid getting an outrageously high water bill.

If you detect any water leaks from the softener to the sewer line, you can turn off the bypass, then call an expert to fix the situation.

How Can I Reduce My Water Bill?

Install Aerators on Your Faucet

An aerator is a small gadget that’s placed on the faucet head to dilute water with oxygen. As a result, the volume of water flowing out of your faucet is reduced, but still maintains a high-pressure flow. So. It’s a win-win situation: high performance and saving on water bill. Aerators play a huge role when it comes to saving water. It can drastically reduce water used.

Regular Checking Of Water Appliances

Inspect the water appliances like faucets, dishwashers, water softeners, and toilets, among others for leaks. If you pay close attention on your appliances, you’ll notice leaks in time and take action immediately. However, if you’ve received a higher water bill but no appliance is leaking, then it’s time to have underground plumbing checked for leaks.

Purchase Appliances That Are Energy Star Accredited

Purchase or upgrade to appliances that are energy rated to allow you save on both water and energy. For instance, you can replace the washing machine and the dishwasher with their energy star rated counterparts.

Consider a Dishwasher than Hand washing

Dish washing requires less water than hand washing. A Regular dishwasher can use 6 gallons in each cycle of washing. Note that a standard faucet has a flow rate of 2 gallons/minute. On average, you might take 3 minutes or more to wash the dishes. A dishwasher helps you save water leading to reduced water bills.
