Since 2004, the World Health Organization (WHO) has proposed an approach to the issue of drinking water protection, based on the Water Safety Plan (WSP): a management and control model, extended to the entire drinking water supply chain. This approach was introduced in Europe by Directive 2015/1787 and in Italy by the Ministry of Health Decree of 14 June 2017.
With the implementation of the new Directive 2020/2184 expected by 12 January 2023, the adoption of WSPs for supply systems will be mandatory and must be realised for the first time by 12 July 2029 and reviewed periodically.
Due to the complexity and extension of the entire water scheme – with all aqueducts converging towards a unified and interconnected water network sorting system – as of 2019 Acea Ato 2 has decided first to analyse the main aqueduct systems, and to operate on the municipal distribution networks at a later time.
In June 2022, the WSPs of the aqueduct systems of Peschiera-Capore, Appio Alessandrino, Simbrivio, Marcio, Laurentino, Nuovo Vergine and Dognaella (covering about the 90% of customers served by the water service) have already been completed and sent to the Ministry of Health.
In order to complete the assessment of the entire water supply chain, as indicated in the WHO guidelines, in 2021 Acea Ato 2 also began the implementation of the WSPs for distribution networks and small supply sources, starting with Guidonia Montecelio, the first municipality outside Rome by number of inhabitants.
