The new ATO organisation gave rise to a mixed sanitation, drinking water management and distribution company: Nuove Acque SpA. SUEZ is responsible for the concession
for 25 years alongside 32 municipal authorities in the Arezzo region and five others from the Siena province. Priority is given to improving water quality, security of distribution and customer relationships.
SUEZ structured its mission in several phases in order to introduce a genuine culture of industrial management of drinking water and wastewater treatment:
Plan work and optimise interventions to develop services
The quality of the water services delivered was a matter for special attention. 300 sites were switched to remote monitoring and all operational processes were revised. Rates of connection within one week rose from 60 % in 2001 to 94 % in 2007.
Secure and develop distribution systems to win clients
SUEZ performed a large amount of work to upgrade and maintain the network. Innovative processes were used, such as gas leak searches with trace gases. To the immense satisfaction of isolated users, 36 km of networks were added. Non-conformities concerning water quality were cut by 90 %.
Protect the environment using innovative wastewater treatment technologies
€36 million was invested in modern and efficient wastewater treatment technologies such as phytopurification, sludge drying by heat or energy co-generation. SUEZ assisted in the construction of 27 wastewater plants in just a decade.
