I was very pleased to watch a film about securing water intakes with mussels. The more so that for over 12 years I have been dealing with the system located on Gruba Kaśka and presented in the above material. I would also like to ask if we, as the Prote company - the only manufacturer and supplier of the SYMBIO system, could place your film on our website? I would be highly obliged for an answer. Regards
