‘Oliena Model’: Hitachi Water Saving Project

A pilot project commissioned by Abbanoa S.p.A. with the support of Hitachi: the 'Oliena Model' has improved the water supply of Oliena by prioritising pressure management, air control and prevention of pressure variations.

Hitachi’s solution is based on an audit of the existing water network, followed by analysis and technical enhancements such as network design, air and water pressure management, and leak detection. The expertise of the Hitachi team and the close collaboration with the partner stakeholders led to a framework of interventions that solved the existing issues and added an efficient stability to Oliena’s water network.

In 2016, Abbanoa S.p.A., with the support of Hitachi and the council of Oliena, undertook an innovative project to reduce the leakages and increase the efficiency of its water supply network.

Oliena’s water supply is guaranteed by a natural source, a spring in the surrounding area named Su Gologone, one of the most important natural sites in Sardinia.

The success of the ‘Oliena model’ has meant that it will now be implemented in other municipalities across Sardinia, 30 municipalities in 2017, followed by 100 in 2018 and another 100 in 2019, saving water and improving supply for the entire island.
