The first waterworks in Torino were built in the middle of the 19th century on concession by a private-owned company called ‘Società Acque Potabili’, which deviated and distributed water from Val Sangone.The Val Sangone and the Venaria waterworks were built the following year and the Pian della Mussa piping was laid in Torino in 1922.
‘Azienda Acquedotto Municipale di Torino’ was founded in 1945. In 1960, the company started acquiring the systems which previously belonged to ‘Società Acque Potabili’.
At the same time, ‘Azienda Acquedotto’ started constructed sanitation systems for the Po river surface water. Three modules, with a total capacity of 2,500 litres per second, were opened from 1960 to 1983.
In 1997, ‘Azienda Acquedotto’ became ‘Azienda Acque Metropolitane Torino S.p.A.’, a mainly public-owned company, and the served area was extended to include 36 towns.
‘Consorzio Po-Sangone’ was founded in 1975 for sanitising waste water. The project involved Torino and 10 suburbs forming the most significant part of the entire Piemonte region in terms of environment impact. The consortium built a piping network connecting the towns to the sanitation system in Castiglione Torinese. The first modules started operation in 1983.
The consortium became ‘Azienda Po Sangone’ on 1 March 1991, forming a streamline company of remarkably high technological level and huge relevance on environmental impact level thanks to the contribution to the revitalisation of the Po river and its tributaries in the Torino area. The collection and sanitation service was extended to 17 towns.
On 1 April 2001, ‘Azienda Acque Metropolitane Torino S.p.A.’ and ‘Azienda Po Sangone’ were merged and formed ‘Società Metropolitana Acque Torino S.p.A. (SMAT)’.
Since then, SMAT has been committed to perfecting the integrated water resource management plan pursuant to Law 36/94. Since 2004, SMAT was appointed for managing the entire water cycle in ATO 3 by Autorità d'Ambito Territoriale Torinese, in collaboration with ACEA of Pinerolo.
In 2005 SMAT, with AMGA of Genova (now IRIDE S.p.A), acquired the majority of shares of SAP (‘Società Acque Potabili S.p.A.’), a stock-exchange company operating nationwide and which, with the support of its controlling companies, is acquiring a role as reference establishment for water service development on the domestic market as a whole.
SMAT started a course targeted at nationwide development by forming a North-West Italy water hub capable of competing with the most important establishments in Italy and aboard, concomitantly with market openings determined by the national integrated water service development and reorganisation.
SMAT currently manages water sources, drinking water sanitation and distribution systems, collection networks, urban waste sanitation and recycling networks in a catchment area which at the end of 2006 reached 212 towns and over two million users.
Also thanks to its local roots, in 2005 SMAT was appointed to engineer and construct the waterworks required to complement the existing infrastructures for the 2006 Olympic Winter Games.
