Since 2007, Garda Uno and Azienda Gardesana Servizi have been working on what Pierlucio Ceresa, the current secretary general of the Garda Community, calls the ‘second phase’ of the Lake Garda collection and purification system. While the current system collects waste from the Brescia and Verona shores to a single plant located in Peschiera, the new projects involve the construction of a new treatment plant in the province of Brescia to collect waste from most of the municipalities on the Brescia shore. However, the decision to change the water basin to which the effluent from this new plant will be sent (the Chiese river rather than the Garda outlet as it is currently) has, however, met with opposition from the Brescia municipalities bordering the latter and from numerous citizens who had held top positions in the Garda Uno administration before Mario Bocchio took over as president. This dispute is still ongoing, even though at the end of January 2026, after changing the location and the number of new treatment plants to be built several times, the final project was drawn up, with completion scheduled for 2035. However, it is not certain that the project will be implemented, as the municipalities on the Chiese river affected by the work could still appeal to the Water Court after the Regional Administrative Court of Lombardia ruled that the matter was not within its jurisdiction. Furthermore, an investigation launched by the Court of Auditors in February 2025 into alleged damage to the public purse due to the doubling of the expected costs is still ongoing. Going back to the origins of the project, it can be seen that the current collection and treatment system has undergone a long and troubled design and construction process, which can be traced back to 1969 and whose conclusion can even be set at 2005, two years before the first feasibility study commissioned by Garda Uno, which provided for its revision. As it is not possible, for reasons of time, to address the entire history of the matter in all its intricate complexity, this thesis aims to lay the foundations for future studies by focusing on its origins. It will be discovered that this project was laden with considerable ideological baggage in which the concept of the Ciellenistic state, embracing the Enlightenment idea of creating a waterway network in the Po Valley, developed an autonomist idea of the Lake Garda region that found its full expression in the renewed attention to local communities during the era of the centre-left government.

Dal 2007 Garda Uno e l’Azienda Gardesana servizi hanno incominciato a progettare quella che l’attuale segretario generale della Comunità del Garda, Pierlucio Ceresa, definisce la “seconda fase” del sistema di collettamento e depurazione circumlacuale del lago di Garda. Se l’attuale sistema prevede il collettamento della sponda bresciana e di quella veronese a un unico impianto ubicato a Peschiera, i nuovi progetti prevedono la realizzazione di un nuovo depuratore ubicato nella provincia di Brescia per il collettamento della maggior parte dei comuni della sponda bresciana. La scelta di cambiare il bacino idrico (Ossia quello limitrofo del Chiese rispetto a all’emissario del Garda come è attualmente) al quale destinare l’effluente di tale nuovo impianto però ha comportato l’opposizione dei comuni bresciani che si affacciano su quest’ultimo e di numerosi cittadini che avevano ricoperto l’apice dell’amministrazione di Garda Uno prima che ne assumesse la presidenza Mario Bocchio. Tale controversia ancora oggi non si è conclusa, anche se a fine gennaio 2026, dopo aver cambiato di nuovo più volte l’ubicazione nonché il numero dei nuovi depuratori da realizzare, è stato redatto il progetto definitivo la cui realizzazione è prevista per il 2035. Tuttavia, non è detto che il progetto verrà realizzato dato che i comuni sul Chiese, interessati dall’opera, potrebbero ancora ricorrere al tribunale delle Acque dopo che il Tar lombardo ha stabilito che la questione non è di sua competenza. Inoltre, contemporaneamente è ancora in corso un’istruttoria avviata dalla Corte dei Conti nel febbraio del 2025 su un presunto danno erariale nel raddoppio dei costi previsti. Risalendo alle origini dell’opera si può notare come l’attuale sistema di collettamento e depurazione abbia attraversato un lungo e travagliato processo di progettazione e realizzazione le cui origini possono esser fatte risalire al 1969 e la cui conclusione si può addirittura fissare al 2005, due anni prima del primo studio di fattibilità commissionato da Garda uno che ne prevedeva la revisione. Non potendo affrontare, per questioni di tempo, l’intera storia della vicenda nella sua intricata complessità, la tesi intende porre le basi per studi futuri focalizzandosi sulle sue origini. Si scoprirà che tale opera è stata caricata di un bagaglio ideologico notevole nella quale la concezione dello stato ciellenistica, facendo propria l’idea illuministica di creare una rete idroviaria padana, ha sviluppato un’idea autonomistica della regione del lago di Garda che ha trovato la sua piena formulazione all’interno della rinnovata attenzione per le comunità zonali dell’età del centro-sinistra programmatico. La tesi intende studiare tale investimento dando particolarmente risalto alla figura centrale di Aventino Frau che ne ha promosso sia la nascita negli anni ’70 che la sua revisione ottenendo a fine 2017 il primo finanziamento da parte dello Stato in 100 milioni di euro.
Il sistema di collettamento e depurazione del lago di Garda: nascita di un’idea.

Abstract
Since 2007, Garda Uno and Azienda Gardesana Servizi have been working on what Pierlucio Ceresa, the current secretary general of the Garda Community, calls the ‘second phase’ of the Lake Garda collection and purification system. While the current system collects waste from the Brescia and Verona shores to a single plant located in Peschiera, the new projects involve the construction of a new treatment plant in the province of Brescia to collect waste from most of the municipalities on the Brescia shore. However, the decision to change the water basin to which the effluent from this new plant will be sent (the Chiese river rather than the Garda outlet as it is currently) has, however, met with opposition from the Brescia municipalities bordering the latter and from numerous citizens who had held top positions in the Garda Uno administration before Mario Bocchio took over as president. This dispute is still ongoing, even though at the end of January 2026, after changing the location and the number of new treatment plants to be built several times, the final project was drawn up, with completion scheduled for 2035. However, it is not certain that the project will be implemented, as the municipalities on the Chiese river affected by the work could still appeal to the Water Court after the Regional Administrative Court of Lombardia ruled that the matter was not within its jurisdiction. Furthermore, an investigation launched by the Court of Auditors in February 2025 into alleged damage to the public purse due to the doubling of the expected costs is still ongoing. Going back to the origins of the project, it can be seen that the current collection and treatment system has undergone a long and troubled design and construction process, which can be traced back to 1969 and whose conclusion can even be set at 2005, two years before the first feasibility study commissioned by Garda Uno, which provided for its revision. As it is not possible, for reasons of time, to address the entire history of the matter in all its intricate complexity, this thesis aims to lay the foundations for future studies by focusing on its origins.
