CIC – Consorzio Irrigazioni Cremonesi

The Consorzio per l'incremento dell'Irrigazione nel territorio Cremonese, also known as Consorzio Irrigazioni Cremonesi (CIC), was founded in March 26,1883, in order to build the Marzano Irrigation ditch (now named after Pietro Vacchelli, Senator of the Kingdom of Italy). This was in fact built between 1887 and 1893.

CIC sprang to life thanks to 59 Cremonesi municipalities sharing the financial burden.

The new ditch was essential to bring more water to the fields and caused the agricultural production in the second part of XIX century to rise steeply.

The only solution was to flow water from Adda river, 35 km away from Tombe Morte place, in Genivolta (CR), climbing over Serio river valley, to reach the ancient water supply network built, during the X century driving from Oglio river and fontanìli (countryside springs), mainly thanks to the Naviglio della Città di Cremona and Condominio Pallavicino's Irrigation ditches.

Originally Pietro Vacchelli ditch was able to drive 25 cube meters: this doubled the water resources of the Cremonese countryside. The flow rate was increased to 37,00 m3/s and, thanks of Como lake regulation, to 38,5.
The Condominio Pallavicino was a private establishment founded by Galeazzo I Pallavicino, in XVI century. The Pallavicinos owned it for centuries in stirpe et non in capita, contrary to the then common family law.
In 1893 Condominio Pallavicino was bought by CIC, with the water supply network driving from Oglio river by means of the following main ditches:

- Roggia Calciana (XIV century);
- Naviglio Grande Pallavicino (XVI);
- Naviglio Nuovo Pallavicino (XVII).

Today the flow rate of the CIC water supply network is 57,779 m3/s, and it is able to irrigate 65000 hectares.
In the XX century the most important improvement was the construction of the Lago di Iseo and Lago di Como dams. They adhered to the shared protocol for water use with Oglio and Adda rivers, so that there is always water available, even in the difficult times.
