TEMPOMATIC 4 urinals achieved a 99% water saving


Outstanding results


For one week’s test, normal water consumption was 10.5 m3. After installation of Delabie’s new Tempomatic 4 urinal flush valve it was 0.102 m3. A 99 percent water saving, representing a saving of £25.93 per week for just two urinal installations.


Spensa continues: ‘Te results were significantly better than we imagined. We were saving an eye watering amount of water and when we look at potentially rolling Tempomatic 4 across 18 buildings, likely millions of litres of water in a year, which translates to several thousands of pounds worth of cost savings in water consumption alone. ‘Tese figures just reflect the water savings. In addition, we know there will be a reduction in ongoing maintenance costs. We don’t expect to be having to react to leaks etc. Installation and maintenance are low. Plus, with a system that has no manual intervention, it’s also more hygienic for users too.


‘In terms of payback, we are looking at 10 months for these two installations to have paid for themselves. Each

system cost just a few hundred pounds to purchase, and we used our in-house labour. Tis means Tempomatic 4 is a really viable option. Our business case is going to the business panel with a recommendation to roll out installation across all 18 buildings, with a payback period of just six months, and a potential saving of over £30k per year.’


Te Tempomatic 4 – intelligent rinsing Below


TEMPOMATIC 4 urinal: a streamlined finish with multiple colour schemes


Te Tempomatic 4 urinal is an intelligent urinal valve that detects high-frequency periods and no activity, adapting its rinse accordingly. During peak periods, only the urinal bowl is rinsed between two users. At the end of the busy period, an additional rinse takes place to clean the bowl completely and renew the water in the trap. Te Tempomatic 4 urinal valve offers three programmes according to the urinal type, each with an optional hygienic duty flush. Te duty flush can be programmed to take place every 12 to 24 hours after the last use to flush the pipework and prevent the crystallisation of uric acid, water stagnation and back flow due to system vacuums.


Te trial


Birkbeck chose to retrofit and trial the Tempomatic 4 urinal plate in two locations in one building. One in the men’s on the fifth floor, where there was a higher use facility, and the second in a much smaller footfall area. Birkbeck measured the output during a normal term-time/working week, taking metre readings to quantify the results.


Full roll out – more savings


‘We are very pleased,’ reaffirmed Spensa. ‘Tis one product will deliver significant savings; it looks nice and is easy to install – I can’t find a downside to the system. I’m a member of the Association of University Engineers and I will be sharing the positive results we have achieved within that forum, as well as endorsing a roll out across our multiple sites.’
