We have two systems suitable for public parks and similar sites. The Full Access Composter is ideal for where use is relatively low and urine can be discharged to ground. For busy sites we have the Zero Discharge 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 examples below.
Some examples of NatSol amenity site toilets:-
Zero Discharge toilets protect England's cleanest lake.
