40 4.1.5 Basins between Capo Passero and Tellaro The hydrographic basin between Capo Passero and Tellaro is 100.1 km 2 . The basin belongs to the administration provinces of Ragusa and Siracusa. During the period 1921-2000 the basin received an average amount of rain between 450-600 mm per year. The total water demand for urban consumption is million 5.3m 3 . 60% of the basin area is cultivated, for a total of 58 million m3 per year for irrigation. 0.5 Million m 3 are consumed for industrial activities. The average infiltration at basin level is estimated to be 104.6 mm per year, which corresponds to 10.5 Million m 2 . Table 8 reports relevant figures.

The basin belongs to the administration provinces of Siracusa. It includes the Tellaro river, 45 km long. During the period 1921-2000 the basin received an average amount of rain between 450 and 600 mm per year. Springs and wells provide about 302l/s of water for a total of 9.5 million m 3 per year. The average total water demand for urban consumption is million 2.2m 3 . 5.1 km 2 of the basin area are irrigated, only 5% is irrigated by a public consortium. The remaining part is irrigated by private wells for a total of 14.8 million m 3 per year. No relevant industrial activity is active in the basin, the total demand per year is about 0.7 Million m 3 . The average infiltration at basin level is estimated to be 212 mm per year, which corresponds to 82.5 Million m 2 . Table 9 reports relevant figures.

The basin belongs to the administration provinces Siracusa. During the period 1921-2000 the basin received an average amount of rain between 600 and 700 mm per year. Springs and wells provide about 4.1 million 0.725 m 3 per year. The total water demand for urban consumption is practically nil. Total agricultural consumption is less than one million m 3 per year, entirely meet by private wells. No industrial consumption. The average infiltration at basin level is estimated to be 53.6 mm per year, which corresponds to 4.98 Million m 3 . Table 10 reports relevant figures.
