We have two systems suitable for public parks and similar sites. The Full Access Composter (FAC) is ideal for where use is relatively low and urine can be discharged to ground. For busy sites we have the Zero Discharge (ZD) system. This can take high levels of use, has zero discharge to ground and requires very little maintenance. See the Richmond Park, Hetland Garden Centre, Falkland Islands and Wasdale amongst the examples below. The ZD now comes in two models depending on your requirements. The ZD1 is for large facilities. The ZD2 is for one or two toilets where the cubicles open directly to the outside world.
Some examples of NatSol amenity site toilets:-
New toilets protect Cardiff's water supply.
Description: NatSol was called in by the National Trust to solve a problem at the very busy lay-by and car park at Pont ar Daf. The site is the principal starting point for walkers going up Pen y Fan, Bannau Brycheiniog. Welsh Water had been concerned for some time about discharges from the old toilet facility which had a septic tank and reed bed. The discharge from the reed bed was only a hundred metres or so from a stream running into the reservoir supplying Cardiff.
As a consequence the facility had been shut and toilet provision was by portaloos.
We proposed a no flush toilet system which we had already installed in the Lake District for a National Trust site. That installation was to protect Wast Water, England's cleanest lake. The design dates back to 2012 when we were asked to design a system for one of London's Royal Parks which is a Site of Special Scientific Interest (SSSI).
The Pont ar Daf site is now up and running and is operating well.
