Prohibition of irrigation and watering of gardens and lawns, prohibition of washing courtyards and squares, prohibition of washing cars with the exception of car washes, prohibition of filling private swimming pools, ornamental fountains and garden tubs. These are the measures to limit the use of water for purposes other than drinking and production purposes deemed necessary by the Liguria Region, which sent a specific communication with the lines to the Municipalities and Government Bodies of the Areas for the integrated water service. guide ‘, based on the results of the monitoring carried out by the Water Use Observatories, established within the Po District and Northern Apennine Authorities. The latter will meet again next week.
In fact, the analyzes show a water critical situation in Liguria, especially in the west, and a high risk for the use of drinking water due to the persistence of the absence of significant rainfall since autumn 2021, a situation aggravated by the summer period characterized by ” increase in temperatures, the scarcity of rainfall, the increase in consumption due to the tourist season.
“We are working with the National Department and the other regions to build a state of national emergency – explain the president of the Liguria Region and the councilor for civil protection – The Po basin is at the highest level of hydraulic severity, while that of the Northern Apennines is of medium severity, although we believe it is plausible that, after the Observatory meeting scheduled for next week, it will reach the highest level for this basin as well. Forecasts are currently not optimistic. We therefore believe that these actions are absolutely necessary to prevent a worsening of the situation and avert the risk of water rationing and concrete inconvenience to citizens and tourists in the coming summer months. It is good to act immediately, hoping for government intervention with specific measures as soon as possible “.
In June in Liguria there was a surge in temperatures, both minimum and maximum, with values well above the climatological averages, with a consequent increase in the needs for water use. The flow rates of the watercourses are also significantly lower than the seasonal average, in western Liguria even close to historical lows. There was also a significant worsening in May, especially in the Imperia and Genoese areas, of the so-called SPI (Standardized Precipitation Index), the international standard indicator normally adopted to quantify the more or less severe drought situation. decrease in all levels of aquifers, mainly groundwater in Liguria The reservoir of Brugneto, in the Genoese hinterland, is suffering from water.
As for rainfall, on average in Genoa, from January to June inclusive, 537.8 mm falls: this year 100.6 has fallen. Similar situation in the other capitals: in Spezia on an average of 722.3 233.8 fell.

The latest rainfall recorded in the provincial capitals was minor: 4.6 mm in Imperia; 6.2 in Savona; 1.4 mm in Genoa; 1.4 mm in La Spezia. The seasonal forecasts on temperature and precipitation drawn up by the European Center for Medium-Term Meteorological Forecasts reveal, between the end of June and the beginning of July, an anomaly in a large area and in particular in Italy and Liguria. As far as rainfall is concerned, in July, rainfall is expected for Liguria below the average or at most coinciding with the climatological average, with very high temperatures.
