# 1998 Gothenburg
After a water supply crisis due to the age of the distribution system and insufficient sources of water, the Municipal Water Supply Co~npanyof Palermo (A.M.A.P.) decided in 1990 to proceed to the acquisition of a new "Preliminary Project of the water supply for the town of Palermo".
Four engineers (Cesare Arici, Gerardo Bonvissuto, Giuseppe Curto and Giovanni di Trapani) were approached for this purpose.
In the project - presented in September of the same year - the characteristic water diagrams for supply of the town were examined. The problems, the deficiencies and the inconveniences of the existing distribution pipeline were analysed and the targets to be achieved were indicated.
