How to Convert Your Existing Urinal to Waterless in 10 Minutes

Still Flushing Money Down the Urinal?

Every time a conventional urinal is flushed, perfectly treated drinking water is used to move waste down the drain. One flush may seem insignificant, but in high-traffic facilities such as offices, malls, airports, schools, and commercial complexes, those litres quickly add up. By the end of the day, thousands of litres of valuable water may have been used for a task that doesn't necessarily require it. What's often overlooked is that this isn't just water going down the drain , it's money. Every flush contributes to higher water bills, increased utility costs, and a larger environmental footprint.

The surprising part is that most facilities continue this cycle simply because "that's how it's always been done." While organizations invest heavily in energy efficiency and sustainability initiatives, many still allow a major source of water waste to go unnoticed in their washrooms. As water scarcity becomes a growing concern and operational costs continue to rise, facility managers are beginning to ask an important question: Why are we still flushing thousands of litres of water every year when smarter alternatives exist? The answer is driving a shift toward waterless solutions that save water, reduce costs, and support sustainability goals without compromising hygiene.

Why Convert to a Waterless Urinal?

Water is becoming one of the most valuable resources for businesses and communities alike, yet conventional urinals continue to use treated drinking water for every flush. In high-traffic facilities such as offices, malls, airports, factories, and educational institutions, this can result in thousands of litres of water being wasted every month. By converting existing urinals to waterless systems, organizations can instantly eliminate this unnecessary consumption, significantly reduce utility costs, and contribute to their sustainability goals without making major changes to their infrastructure.

Beyond water savings, waterless urinal retrofits offer operational and maintenance benefits that many facility managers overlook. Traditional urinals rely on flush valves, sensors, pipes, and other components that require regular maintenance and repairs. Waterless systems simplify restroom operations by reducing moving parts and minimizing plumbing-related issues. The result is lower maintenance costs, fewer service interruptions, improved restroom hygiene, and a measurable reduction in environmental impact. For organizations looking to improve efficiency while demonstrating responsible resource management, converting to waterless urinals is a practical and cost-effective solution.

The Common Myth: “We Need to Replace the Entire Urinal”

One of the biggest reasons organizations delay adopting waterless urinals is the belief that the transition requires a complete restroom renovation. Many facility managers assume they will need to remove existing urinals, break tiles, modify plumbing lines, and invest heavily in new fixtures. As a result, water-saving projects are often postponed because they seem too expensive, disruptive, and time-consuming. In reality, most of these concerns are based on outdated information and misconceptions about how modern waterless urinal technology works.

The truth is that most existing ceramic urinals can be converted into waterless urinals through a simple retrofit process. Instead of replacing the entire fixture, a specialized waterless cartridge or trap system is installed within the existing urinal, allowing it to operate without flushing water. This means there is no need for demolition, major plumbing alterations, or lengthy restroom closures. The conversion can often be completed within minutes, making it one of the quickest and most cost-effective ways for organizations to reduce water consumption and improve sustainability without disrupting daily operations.

What Is a Waterless Urinal Retrofit?

A waterless urinal retrofit is a simple upgrade that transforms an existing flush urinal into a waterless system without requiring the replacement of the entire fixture. Instead of removing the urinal and undertaking costly plumbing work, a specially designed waterless cartridge or trap is installed within the existing drainage outlet. This cartridge allows urine to flow directly into the drainage system while preventing sewer gases and unpleasant odors from escaping back into the restroom. The result is a fully functional urinal that operates without using any flushing water.

The biggest advantage of a retrofit is that it leverages the infrastructure already in place. The original ceramic urinal remains on the wall, and there is typically no need for demolition, pipe relocation, or extensive renovations. This makes waterless retrofits an ideal solution for offices, malls, factories, airports, educational institutions, and other facilities looking to reduce water consumption quickly and cost-effectively. By converting existing urinals rather than replacing them, organizations can achieve substantial water savings, lower operating costs, and support sustainability goals with minimal disruption to daily operations.

How to Convert an Existing Urinal to Waterless in 10 Minutes

Converting an existing urinal into a waterless urinal is a straightforward process that requires minimal effort and no major plumbing modifications. The first step is to turn off the water supply connected to the urinal and remove any existing flushing components or drain covers as required. Once the outlet area is accessible, it should be cleaned thoroughly to remove dirt, scale, and debris that may affect the performance of the retrofit system. This preparation ensures a secure fit and helps maintain optimal drainage and odor control.

After the cleaning is complete, the waterless retrofit cartridge or trap is installed into the existing drain opening. The cartridge is engineered to allow urine to flow freely into the drainage system while creating a barrier that prevents sewer gases and unpleasant odors from escaping. Once the cartridge is properly secured, a quick functionality check is performed to confirm smooth drainage. The entire conversion can often be completed in around 10 minutes, transforming a conventional urinal into a water-saving solution without replacing the fixture, disrupting restroom operations, or requiring extensive maintenance work.

Step 1: Turn Off the Water Supply

Locate the water inlet connected to the urinal and close the valve.

This immediately stops unnecessary water flow during installation.

Step 2: Remove the Existing Waste Trap or Drain Cover

Most conventional urinals have a waste outlet assembly already installed.

Remove the existing component carefully.

No specialized tools are usually required.

Step 3: Clean the Drain Opening

Remove any scale buildup, dirt, or debris around the drain area.

A clean surface ensures proper fitting and odor control.

Step 4: Install the Waterless System

Insert the retrofit cartridge according to the manufacturer's instructions.

The cartridge is designed to:

• Allow urine to pass through

• Prevent sewer gases from returning

• Control odors effectively

This is the core component that makes waterless operation possible.

Step 5: Secure and Test

Ensure the cartridge is seated properly.

Pour a small amount of liquid through the system to confirm smooth drainage.

The urinal is now ready for use.

No flushing required.

How Does a Waterless Urinal Prevent Bad Odors?

One of the most common concerns about waterless urinals is whether eliminating the flush will lead to unpleasant smells. Surprisingly, many odor issues in conventional urinals are not caused by the absence of water but by the presence of scale buildup, stagnant water, bacteria, and sewer gas leaks within the drainage system. Over time, mineral deposits and organic matter can accumulate inside pipes and traps, creating an environment where odors develop and persist despite regular flushing. This is why some traditional urinals continue to smell even when they use large amounts of water every day.

Waterless urinals address this problem through specially designed cartridge or trap technology that acts as a barrier between the restroom and the sewer line. The cartridge allows urine to flow freely into the drainage system while preventing sewer gases from traveling back into the washroom. As a result, unpleasant odors are effectively contained at their source rather than being masked by continuous flushing. When maintained according to manufacturer guidelines, waterless urinals can provide a clean, odor-free restroom experience while eliminating water consumption and reducing maintenance requirements.

Additional Benefits Beyond Water Savings

While water conservation is the most obvious advantage of a waterless urinal retrofit, the benefits extend far beyond reduced water consumption. Traditional urinals rely on flush valves, sensors, pipes, and other mechanical components that can wear out over time, leading to leaks, repairs, and ongoing maintenance expenses. Waterless systems eliminate many of these potential failure points, helping facilities reduce maintenance requirements and minimize downtime. With fewer moving parts to service and replace, facility managers can spend less time addressing restroom issues and more time focusing on operational efficiency.

Waterless urinals also support broader sustainability and cost-reduction goals. Lower water usage translates directly into reduced utility bills, while decreased demand on plumbing infrastructure can contribute to long-term operational savings. In addition, organizations can strengthen their environmental credentials by demonstrating measurable water conservation efforts, which can support ESG initiatives, sustainability reporting, and green building certification programs. For businesses looking to improve both environmental performance and financial efficiency, a waterless urinal retrofit delivers benefits that continue long after the installation is complete.
