Why are waterless urinals better than flush urinals?

Waterless urinals have been common practice in countries who are leading the way with water conservation and improved facilities. Countries such as America, Germany and Switzerland to name but a few. In fact there are over 355,000 of our waterless urinals installed across 55 countries including installations in the Miami Dolphins Stadium, Camp Nou in Barcelona, and The Bank of America, all of which have been installed for many years and have proved successful.


The benefits of installing waterless urinals can be split into 3 sections; facilities and maintenance, environmental and financial.


Facilities and Maintenance Benefits. (+) Click to open

Washrooms that have had flush urinals installed for a period of time will notice the same kinds of issues. Namely blocked pipes, flooded wash rooms and bad odours. No matter how often they are cleaned, they still suffer from these issues. Our waterless urinals reduce wash room odours, prevent blocked pipes and therefore prevent flooded wash rooms. They also require less maintenance, so they not only improve washroom facilities, they reduce the time and cost of ongoing maintenance.

Why don’t waterless urinals get blocked? (+) Click to open

Surprisingly water is the main cause of blocked pipes and flooded washrooms. Lime scale in water mixes with the uric sediment in urine and forms solid waste, this solid waste lines the waste pipe and over time builds up and causes blocked pipes. 


The natural reaction is to increase the amount of water that is flushed through the urinals, but all this does is
increase the amount of lime scale deposited in the waste pipe, causing further blockages and flooded wash rooms.

Waterless urinals don’t use water and as a result there is no lime scale being deposited in the waste pipe. Urine is only 3% waste (uric sediment) and 97% water, the patented cartridge in an Eco Ad waterless urinal acts like a filter and collects all of the waste before the urine passes into the waste pipe.

Urine is essentially odourless. Bad odour is the result of urine being mixed with air and water causing a chemical reaction which creates ammonia gas, the odour we associate with men’s wash rooms. A flush urinal uses a P-trap just below the urinal. This P-trap is exposed to the washroom and holds a pool of urine and so causes bad odour. When the cistern flushes, more water hits the pool of urine and creates more ammonia gas aka bad odours!

As our system doesn’t use water, the chemical reaction can’t take place and so no ammonia gas is created meaning no bad odours! The urine passes through an air tight seal and into the patented cartridge where all of the waste is filtered out before passing the fluid into the waste pipe, so there is no pooling of urine.

The cartridge in our urinal is locked in using a key, forming an airtight seal between the waste pipe and the wash room. Inside the cartridge is a biodegradable oil which is less dense than water, so this forms an additional airtight seal between the cartridge and the washroom locking any bad odours into the cartridge making the cartridge 500 times more effective than a P-trap.

A common misconception is that flush urinals must be clean due them being constantly flushed. If the water being used was anti-bacterial, then this would be the case, but it’s not. Bacteria requires a moist environment to grow, like that of a flush urinal. There are certain areas of a flush urinal that are hot spots for bacteria, like the parts that aren’t in the direct path of the flush. Bacteria thrives in these areas and every time the urinal flushes, the bacteria becomes airborne.

Eco Ad waterless urinals are made of a nonporous virtuous china, as there is no water the bowls dry extremely quickly. All of the urine is locked into the cartridge by an airtight seal which means that the conditions are not suitable for the growth of bacteria. Research has shown that our waterless urinals have 5.7 times less bacteria growth.

How do waterless urinals reduce maintenance? (+) Click to open

Due there being no lime scale build up, there is no solid waste on the urinal bowl so cleaning is incredibly easy. Simply spray, wipe and you’re done! As waterless urinals reduce bad odours, there is no need to use urinal cakes and therefore the need to constantly replace them. 

Environmental Benefits (+) Click to open

Flush urinals use a significant amount of water to flush away a small amount of waste. As waterless urinals don’t use any water, they save 100% of the water and also help to reduce CO2 emissions. That means that by installing our waterless urinals you can contribute to your BREEAM rating. 

How much water do waterless urinals save? (+) Click to open

Washrooms that have flush sensors installed will use an average of 60,000 litres and those without will use around 150,000 litres of water, all of which has been treated to become drinking water. When you consider that less than 2% of the world’s water is drinkable, it’s obvious that using water to flush away urine, is a waste of water! 

How do waterless urinals reduce CO2 emissions? (+) Click to open

The average bladder holds between 300 to 400ml of urine and the average cistern will flush between 9 to 15 litres of water into the sewer. Once combined, all of that liquid has to be treated at the sewage plant. The treatment of which generates an average of 10 to 26kgs of CO2 emissions every year.

As our waterless urinals don’t require the 9 to 15 litres of water, there is only 300 to 400ml of waste being sent on for treatment at the sewage plant, thus reducing the CO2 generated. 

Financial Benefit (+) Click to open

Waterless urinals save 100% of the costs associated with flush urinals as they use no water, they will also reduce ongoing maintenance costs. Eco Ad urinals also have a built in advertising space which generate a new revenue stream into your business. If you are looking to install our urinals in a place with no public footfall, the space can be used to promote internal messages.

How much money will waterless urinals save against a water bill? (+) Click to open

There are a number of water companies across the UK and each have their own charges for both the supply of water and sewage, so the savings will vary depending on your location. The combined charge for water and sewage is between £1.87m3 (cubic metre) and £3.83m.

Urinals with a flush sensor - use an average of 60,000 litres of water (60m3) which means every urinal replaced will see a saving of £112 to £230 a year.

Urinals without a flush sensor – use an average of 150,000 litres of water (150m3) which means every urinal replaced will see a saving of £2780 to £576 a year.

How do waterless urinals generate a new revenue? (+) Click to open

Each Eco Ad waterless urinal has a built in advertising space measuring 10x4.5 inches. Due to having the user’s undivided attention for an average of 30 to 50 seconds, the advertising demands a high remembrance rate. Eco Ad manage the advertising space and pay back a percentage of the revenue back to you. By utilising the advertising scape we can offer a speedy payback period and a high return on investment.
