For years, the domestic water supply network has been affected by problems caused by the poor state of repair and maintenance of the existing hydraulic infrastructure.

In particular, the age and conditions of the large pipelines – works of fundamental strategic importance – and their orography have probably been responsible for disruptions in the supply of water over time. Such situations are often aggravated by problems of a technical and economic nature which may arise when the utility companies are obliged to cope with asbestos cement pipes. According to estimates, the network of asbestos cement pipes amounts to some 125,000 km in Italy.

Asbestos cement pipes, in diameters usually between 150 mm and 500 mm, have been used for making water supply networks since 1916. Their use continued uninterruptedly from the \u201850\u2019s to the \u201880\u2019s owing to their \u2018optimum\u2019 properties: nothing was yet known of the danger of asbestos fibre.

Use of \u2018trenchless technologies\u2019 has often been discussed in this context as a way of overcoming individual problems relating to large-scale water supply network rehabilitation projects (networks that cross thoroughfares, for example).
Extensive use of trenchless technologies during the execution of a large-scale water supply rehabilitation project has never been called into question. <\/p>

The principal, Abbanoa SpA, sole integrated water supply service utility for the Sardinia region, decided to take advantage of this opportunity by using trenchless techniques to rehabilitate 6 km of DN500 asbestos cement water supply pipeline situated in the Bosa (OR) locality. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
