Waterless urinals – introducing the AirFlush

AirFlush Urinal schematicAirFlushTM urinals were developed by Nick Grant, one of NatSol's founding directors, and Mark Moodie. Later they were marketed by the Green Building Store and this year NatSol took over the business. AirFlushTM works by creating a negative pressure in the urinal pipework so that odour from urine in the pipes does not enter the urinal area. There are no chemical blocks to replace and maintenance is very straightforward.

NatSol can supply complete systems or replacement parts. Go to: AirFlush

Toilet tops

Full Access ComposterWe've been experimenting with the use of Corian (better known as a kitchen worktop material) for our toilet tops. The one shown left is on a Full Access Composting toilet. We first trialled this material for the Zero Discharge (ZD) toilets supplied to The Royal Parks in 2014. One would normally expect toilet seats with lids and hinges to be replaced at least once a year in public facilities. The toilets in Richmond Park have now been in use for 8 years and have been used by hundreds of thousands of visitors but have not yet needed resurfacing; a simple 15 min job which involves rubbing back with very fine emery paper.

The narrow opening was also an experiment at Richmond Park and after 8 years can be considered highly successful. It reduces light transmission down the pedestal, regulates ventilation airflow, and is very safe for young children. It is now standard on ZD pedestals. Go to: Zero Discharge.

So, following on from the success of Corian for ZD toilet pedestals we decided to try using it on our best selling toilet, the Full Access Composter (FAC) seen above.

Our toilets tops for the FAC have been lacquered birch ply with a conventional plastic toilet seat and lid on top. Good quality Forest Stewardship Council certified birch ply is becoming very difficult to get and, for obvious reasons, we have not been buying material sourced from Russia since March 22. The plastic toilet seats have also become difficult to obtain, due either to Brexit or Covid; we are not sure which. So we are promoting Corian for these pedestals too. It costs us a little more but we are absorbing that for the time being and we hope that it will quickly be accepted for its hygienic finish and streamlined appearance.

The ZD2 gets out and about.

Zero Discharge toilets at a sculpture parkA couple of years ago the Zero Discharge toilet split into two types; the ZD1 and the ZD2.

The ZD1 is for large facilities where there are likely to be a number of cubicles. Usually, an architect designs the building. NatSol has supplied ZD1s for public parks such as Richmond Park in London and the Lake District National Park.

ZD2s are for single or perhaps double cubicles in remote locations. The two shown above are on a sculpture park in Dorset. The client arranged the building design, manufacture and supply.

ZD2s are emptied by removing the pedestal, ventilation is likely to be passive. ZD1s have a row of emptying hatches to the rear of the building and ventilation is likely to be fan driven. A vacuum sludge tanker is required to empty both types. For more information go to: Zero Discharge.
