Based on Gentworks survey data from hundreds of sites, the average annual water use per urinal is approximately 120 cubic metres (m3) per year. However, usage varies from around 29m3 to 235m3, depending on the level of flush control already implemented.
Almost all standard urinals can be converted to waterless, whether the urinals are newly purchased or were installed many years ago.
The fitting process is straightforward but requires care and diligence.
The components can be purchased from Gentworks for fitting by the on-site maintenance team or by a local plumbing firm.
No more wasting potable water to flush urinals and reduces load of sewage treatment plants.
GW6-15 Waterless Urinal Conversion Kit
A smaller version of the long-established GW6 cartridge, the GW6-15 is designed to fit urinals that take a 1.5" BSP waste outlet. It has been thoroughly tested at customer sites and in the laboratory, with many refinements being made since its introduction in 2017. The GW6-15 allows odour-free operation in waterless urinals as well as those being low flushed, even if only once per week. It also works with normal flush frequencies but the main purpose of the cartridge is usually to save water, and therefore reduce carbon footprint. A special silicone formula used in production of the dual "skirt" valves gives good tolerance of common cleaning chemicals within the pH range of 4 to 10. Typical life is 6 to 9 months but harsher cleaning products may reduce this. The hole diameter required in the ceramic of the urinal to accommodate this conversion kit is 50mm +/-1.5 mm Included: Features: Recommended to be used in conjunction with Bactericidal Cleaner; sluicing once every 2 weeks, to extend valve life and keep waste pipes clear. |

(ex VAT)Aquafree Waterless Urinal Start-Up Conversion Kit
Aquafree Urinal Maintenance Devices are simply retrofitted into existing pipework. They combat smells and blockages whilst eliminating the need for water. The contents of the standard Waterless Start-up Kits enable urinals to operate with no flushing for a period of 3 months, after which new Aquafree cartridges will be required. Microbes dispensed by the cartridges break down the uric acid salts and other contents of urine, while regular use of Bactericidal Cleaner helps keep the pipework free from body fats, hair, and other debris.
Standard Aquafree kit for conversion and first 3 months of waterless operation includes:
1 x Aquafree Urinal Maintenance Device cartridge designed to dispense beneficial microbes and other active ingredients over a 3 month period.
1 x Waste outlet fitting into which the cartridge is inserted. Please select the appropriate one in the option. If you find that you have ordered the wrong size, please contact us for a free substitute.
At least 1 x 5 litre container of Gentworks Bactericidal Cleaner concentrate to use for weekly dosing and regular cleaning.
Click the tab above for details of the exact quantity of Bactericidal Cleaner supplied depending on the number of urinals and timescale selected.
How to Use Gentworks Bactericidal Cleaner:
Cleaning of urinal: Dilute 10:1, spray, and wipe as with other cleaning fluids.
Weekly dosing: Mix approximately 100ml of Gentworks Bactericidal Cleaner with 900ml of warm water, then pour over and around the dome of the Urinal Maintenance Device. A 5-litre container typically lasts 10 to 11 months for 1 urinal bowl.
Note that cleaning products containing acids, strong alkalis and bleaches must not be used as these will kill the active ingredients.

(ex VAT)Low Flush Urinal Cistern Timer (1-15 hour) Cistern Purge
Mains version OUT OF STOCK - More due in Mid-January.
This Ultra-Low Flush controller can initiate a flush every 7 days so that the standing water in the cistern and flush pipes will be regularly 'purged', thus usually avoiding the need to carry out a dead-leg procedure to minimise the risk of legionella. This controllers is also used in conjunction with Gentworks Urinal Maintenance Devices operating in waterless mode for sites where the weekly dosing procedure is difficult to adhere to. For example, if the expectation is that urinals may only be dosed with Bactericidal Cleaner every 2 to 3 weeks rather than weekly, then the Ultra-Low Flush controller will help to ensure that debris is flushed away regularly. This is not as effective as weekly dosing but is a good compromise. ![]()
