Purification of the Brescia side of Lake Garda

Acque Bresciane opened a phase of information and listening to local stakeholders to illustrate the solutions identified for the new collection and purification system on the Brescia side of Lake Garda and to collect doubts and questions to be forwarded to the bodies called upon to choose the hypothesis to be discussed at the Services Conference. 

On this page Acque Bresciane makes the most significant documents of the process available to citizens.

On 16 June, Acque Bresciane delivered the new documentation requested by the Brescia Area Office:

  • the technical and economic feasibility project for the Lonato - Peschiera solution, complete with timetable
  • the updated time schedule for the Gavardo - Montichiari - Peschiera solution;
  • the report on the condition of the Toscolano Maderno - Torri del Benaco sublacustrades, drawn up at the end of the maintenance work on the deep water from March 2021.

The latter shows that the number and severity of bioconcretions have remained substantially unchanged since the 2020 inspections. Based on these findings and due to the delicate nature of the lake environment, a new Safety Plan was drawn up, based on the most modern international standards, providing for

  • the setting up of a permanent pontoon to reduce the time required for future interventions;
  • scheduling by the end of the year the next inspections, originally planned for spring 2022;
  • the drafting of a plan to replace the two sections most affected by the concretions with polyethylene material in the event of a resumption of the proliferation of the microorganisms responsible for the bioconcretions.

It should be noted that the sublacustrine pipelines from Toscolano Maderno to Torri del Benaco will in any case have to be decommissioned, since the Veronese shore collection and treatment scheme does not provide for the collection and treatment of effluent from the Brescia shore.

In addition to the 2021 Technical and Economic Feasibility Project - Lonato Solution, sent to ATO on 16.06.2021, on 20.07.2021 Acque Bresciane sent the Architectural and Landscape Integration Study of the Lonato wastewater treatment plant, as already developed for the 2019 Project regarding the wastewater treatment plant located in Gavardo.

The architectural and landscape study of the Lonato water treatment plant foresees the realization of an agricultural park and a wetland open to the public, a didactic and agronomic research area, a co-working area and a sales point for products for local consumption.

The project for a new collection and purification scheme for Lake Garda is the subject of a program agreement signed in 2017 between the Ministry of the Environment and Protection of Land and Sea, the Lombardy Region and the Veneto Region. The agreement was followed in December 2017 by an operational Convention between the Ministry, the Regions, the Brescia Area Office, the Verona Basin Council and the Garda Ambiente temporary purpose association. The Convention established a Steering Committee composed of the same actors.

In 2018, Acque Bresciane commissioned a study from the University of Brescia, which was transmitted to ATO together with a technical and economic feasibility project in July 2019.

In February 2020, the Ministry of the Environment and Protection of Land and Sea established a technical panel to assess the environmental impacts of the new purification system on the Chiese River. The Ministry's final report declared the compatibility of the Chiese River with the possible discharge.

In response to the request received from Ato on December 17, 2020, to identify new location hypotheses in line with the Motion in order to update the 2020 Guidelines for the Provincial Special Company of the Province of Brescia Office Brescia approved by the Provincial Council on November 30, 2020, Acque Bresciane has deepened the evaluation of a new location for wastewater treatment.

This evaluation was sent to Ato on April 9, 2021, accompanied by a comparative analysis of the project option in 2019 and the new location.

As stated in the letter accompanying the documentation, Acque Bresciane undertakes to transmit to Ato as part of the documents the comments and proposals arising from the online working tables that will present the possible alternatives to stakeholders.
