Genoa – 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 ones deemed necessary by the Liguria Region, which sent a specific communication with the ‘guidelines’ to the Municipalities and government bodies of the areas for the integrated water service, based on the results of the monitoring carried out by the Water Use Observatories, established in within the scope of the Po and Northern Apennine District Authorities. The latter will meet again next week.
From the analyzes it emerges in fact in Liguria a water critical situation, 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 the increase in temperatures, the scarcity of rainfall, the increase in consumption due to the tourist season.
“We are working with the national Department and other regions for the construction of the national state of 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, even if we believe it plausible that, after the Observatory meeting scheduled for next week, it will go to 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 average climatological, with a consequent increase in the needs of 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.
All levels of groundwater are decreasing, mainly phreatic 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 La Spezia, on an average of 722.3, 233.8 fell. In Savona, on an average of 422.3, 115.6 fell, in Imperia on an average of 327.2, 90 fell. In Imperia and Genoa it has not rained for about 40 days. 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 for rainfall, in the month of July, for Liguria below average rainfall is expected or at most coinciding with the climatological average, with very high temperatures.
Giampedrone: “Watermaker in Genoa? Ok but not for emergency “
“The desalinator is not just the idea of Mayor Bucci, it is talked about throughout Italy: it is obvious that any system that can allow the use of sea water for different purposes is something to think about, but I don’t know if it is compatible. with the times with which we should move because we have an immediate need to implement civil protection measures. However, it could be a measure to be implemented, based on the Pnrr, by 2026 “. Thus the Councilor for the Environment and Civil Protection of the Liguria Region, Giacomo Giampedrone, on the sidelines of a press conference after the arrival, in which he was discussed the state of the water reservoirs of the territory.
“We asked for the approval process of PNRR funds on the overgrown plan to be accelerated – adds Giampedrone – Liguria Region has over 27 million at stake for water infrastructuresespecially for the pipes of the wells of Roja and the west: this would give us a great hand, not the day after tomorrow, but in a perspective that, with these forecasts and with the climate changes that are being felt, will be a theme that will also return in the next years”.
