Why Are Your Property's Water Bills So High?

Why Are Your Property's Water Bills So High?

High water bills can significantly concern property owners. Understanding the potential causes is crucial to managing and reducing these expenses effectively. Here’s a detailed look at why your property’s water bills might be soaring and what you can do about it.

1. Leaks

Leaks are often the primary reason for unexpected spikes in water bills. They can occur in various parts of the plumbing system, including:

Faucets and Showerheads

Even a small drip can waste gallons of water over time. For instance, a faucet dripping at one drop per second can waste more than 3,000 gallons of water annually. Showerheads with slow drips can add significantly to your water usage.


A running toilet can waste up to 200 gallons of water per day. Common causes include worn flapper valves, improperly adjusted fill valves, or leaks from the tank to the bowl.


Hidden leaks in walls, ceilings, or underground can go unnoticed for long periods, leading to substantial water loss. Signs of hidden leaks include damp spots, mold growth, or unexplained drops in water pressure.

2. Inefficient Fixtures and Appliances

Older or inefficient water fixtures and appliances can use significantly more water than newer, water-efficient models. Common culprits include:


Older toilet models can use up to 1.6 gallons per flush, while modern, high-efficiency toilets use as little as 0.8 GPF gallons per flush. This difference can significantly impact water usage, especially in properties with multiple units or high occupancy.

Showerheads and Faucets

Older fixtures often have higher flow rates, with some older showerheads using up to 5 gallons per minute (gpm) compared to modern models that use 1.25 gpm.

Washing Machines and Dishwashers

Older appliances can be water guzzlers compared to modern, efficient models. For example, older washing machines might use up to 40 gallons per load, whereas high-efficiency models use less than 25 gallons.

3. Excessive Irrigation

Outdoor irrigation can account for a substantial portion of your water bill, especially if not managed properly. Issues include:


Using more water than necessary for landscaping wastes water and can damage plants and soil. Overwatering is often due to incorrect timer settings or a lack of seasonal adjustments.

Irrigation System Leaks

Faulty sprinkler heads, cracked pipes, or disconnected lines can lead to significant water loss. Leaks in underground irrigation systems can be particularly challenging to detect.


Watering during the heat of the day leads to higher evaporation rates, meaning more water is required to achieve the same effect.

4. High Water Pressure

Excessive water pressure can lead to increased water usage and put stress on your plumbing system, causing leaks. The ideal water pressure is between 40 and 60 psi. High pressure can cause pipes to burst and fixtures to fail prematurely.

5. Unaccounted Usage

Unaccounted water usage can contribute to higher bills in properties with multiple tenants or units. This can include:

Unauthorized Use

Tenants or others using water without permission can significantly impact water usage. This might include unauthorized car washing, lawn watering, or filling pools.

Shared Facilities

Common areas like laundry rooms, pools, and shared bathrooms can significantly impact the bill. Inadequate monitoring and usage policies can lead to excessive water consumption.

6. Seasonal Factors

Water usage typically increases during warmer months due to activities like filling pools, increased irrigation, and higher consumption due to the heat. Seasonal events, such as summer or holidays, often increase occupancy and water usage.

7. Faulty Water Meter

Sometimes, the problem might lie with the water meter itself. A malfunctioning or misread meter can result in inaccurate billing. Water meters can become less accurate over time due to wear and tear.

8. Behavioral Factors

Simple habits and behaviors can also contribute to high water usage, such as:

Long Showers

Prolonged shower times significantly increase water consumption. A typical shower uses 2.5 gallons per minute, so a 10-minute shower uses 25 gallons, while a 20-minute shower doubles that amount.

Running Water

Leaving water running while brushing teeth, washing dishes, or shaving can waste considerable water.

9. Aging Infrastructure

Older or poorly designed water management systems can lead to inefficiencies and higher water usage. This includes outdated plumbing infrastructure that is not optimized for conservation.

10. Environmental Factors

Environmental issues such as droughts or water restrictions can affect water availability and cost, potentially leading to higher bills. Water providers may increase rates during drought conditions to encourage conservation.

Smart Water Monitoring Systems: A Comprehensive Solution

Implementing smart water monitoring systems is a highly effective solution for managing and reducing water bills. These systems provide real-time data on water usage, allowing property owners and managers to promptly detect anomalies such as leaks, excessive consumption, or inefficient water use. Smart sensors allow water monitoring systems to pinpoint the exact location and cause of water waste, enabling swift corrective actions. Additionally, these systems can generate detailed reports and analytics, helping to identify patterns and trends in water usage.

This data-driven approach not only aids in immediate cost savings but also supports long-term water conservation strategies, ultimately leading to more sustainable water management practices and significant financial benefits. Investing in advanced water monitoring technology is essential to achieving greater efficiency, reducing waste, and ensuring the responsible use of this vital resource.

Wrapping Up

High water bills can stem from various sources, from leaks and inefficient fixtures to behavioural habits and environmental factors. By understanding these potential causes and implementing practical solutions, property owners and managers can take significant steps toward reducing water consumption and lowering bills.
