                    In order to avoid drain clogging or smelling deposits inside 
                    sewerage pipes, ECOPLAST has patented a self-cleaning device, 
                    allowing automatic and emptying by gravity. 
                     
                  
                   
                    This system is based on a simple but proven mechanism, the 
                    "water closed" type, and is equiped according to 
                    local characteristics :

                    self-cleaning tanks have numerous applications in water supply 
                    and sewerage systems.  
                  
                   In 
                    particular, an ECOPLAST self-cleaning tank is the component 
                    that guarantees long term sustainability of trickling trenches.
