Grup CASSA (Companyia d’Aigües de Sabadell, SA) supplies water to over 800,000 users in 60 municipalities and is one of the leading water concessionaires in Catalonia and Spain. In 2004, we were commissioned to design its logo and corporate identity manual. We opted for the humanist typeface Frutiger, designed by Adrian Frutiger in 1976. It is a simple, clear and solid typeface that conveys the values of the company. The symbol was designed using the same forms as the letters in order to blend in with the typeface.
