About the Consorzio
The Consorzio Depurazione Acque Biasca e dintorni is a purpose association (consorzio) based in Biasca in the canton of Ticino. Its purpose is to conduct all activities and infrastructures for wastewater treatment of the connected municipalities. The IDA wastewater treatment plant in the Alla Giustizia zone south of Biasca is operated; wastewater treatment takes place in three stages: mechanical (screens, circular grit chamber, primary clarification), biological (activated sludge process with aeration, secondary clarification) and chemical (dosed precipitation of dissolved phosphorus). The treated water is discharged into the Ticino; the sewage sludge is dewatered, digested and partially reused. The catchment area includes Biasca, Riviera, Iragna, Pollegio, Personico, Giornico, Serravalle, Acquarossa and Faido. In addition, the consorzio offers tours and awareness programs for schools and groups.

Wastewater Treatment Processes
Mechanical treatment stage
Removal of coarse solids (textiles, paper, plastic, wood) by screens, as well as grit separation and primary clarification.
Activated sludge process
Aeration to promote aerobic microorganisms for the degradation of the remaining biodegradable pollutants, followed by secondary clarification and sludge separation.
Chemical treatment stage
Dosage of reagents to reduce dissolved phosphorus.

Water Quality and Monitoring
The water quality at the plant outlet is continuously measured and published on the website; among other things, pH value, CDO, total phosphorus, transparency and suspended solids are displayed against the limit values of the OPAC.
