Campania’s citizens to benefit from water treatment refurbishment

A major EU-funded project to rehabilitate five water treatment plants in Italy’s Campania region will lead to supply improvements, energy efficiencies and local employment opportunities.

The “Environmental rehabilitation and valorisation of Regi Lagni” is a long term project that will dramatically improve the provision of water services to a population of over 2 million. Commissioner for Regional Policy Corina Creţu has described the project as “one of the most important to be approved in Campania by the Commission, both in financial and impact terms”. 

The Regi Lagni is a system of artificial channels originally built in the 17th century to collect rainfall and spring water. Regi Lagni’s basin crosses the provinces of Caserta, Avellino, Napoli and Benevento, all located within Campania. This infrastructure has been in need of extensive refurbishment. 

Sustainable benefits for citizens 

The project consists of rehabilitating existing wastewater treatment plants in the Northern province of Naples, where some 38 % of Campania’s population lives. The work also involves repairing or substituting mechanical parts and equipment that had deteriorated or were no longer functional. 

The work will include the renovation of five treatment plants at Acerra, Napoli Nord,  Marcianise Foce Regi Lagni and Cuma. 

At all these sites, the project will carry out work to improve the treatment of nitrogen and phosphorus; the final filtration and UV disinfection of purified wastewater; and the treatment of sludge through anaerobic digestion and the thermal drying process. Another key aim of the project will be to boost the co-generation of electricity and heat using biogas and to put in place environmental mitigation works.

In addition, two new sewage collectors and a connection between collectors are being constructed. Taken together, the new plants will be capable of treating 166 510 080 cubic metres of water annually, improving living conditions for residents.

Environmental focus 

The project is part of the region's global water management strategy aimed at rehabilitating and preserving one of Italy’s most polluted areas, and ensuring compliance with the EU’s Water Framework Directive (2000/60EC). 

The newly refurbished infrastructure has also been designed to be more energy efficient, and aims to reduce greenhouse gas emissions by some 1 900 tonnes as a result. 

Total investment and EU funding 

Total investment for the project “Environmental rehabilitation and valorisation of Regi Lagni” is EUR 200 000 000, with the EU’s European Regional Development Fund contributing EUR 150 000 000 through the “Campania” Operational Programme for the 2007-2013 programming period.
