Major upgrade of sewage network in Campania to benefit local citizens

A major project to improve water quality in Italy’s South West Campania region will result in new waste treatment plants, refurbished connections and pipelines and a significant extension of the sewage network.

Additional tools


The “Risanamento Ambientale Corpi idrici Superficiali delle Aree Interne” project aims to restore the water quality of the Volturno river, along with some of its tributaries, in the Campania region of South West Italy. This will bring significant benefits to the 194 000 citizens in the provinces of Avellino, Benevento and Caserta who rely on this river for water, and will ensure the long term environmental sustainability of water supplies across the region.

Major water works 

To achieve this, the project will carry out major works to improve  wastewater treatment and to improve the area's sewage system. The project will cover 46 municipalities in the three provinces, and will involve 37 individual interconnected interventions at the municipal level.

A total of four new inter-municipal and six new municipal sewage treatment plants will be constructed. The new inter-municipal sewage treatment plants will carry out the secondary treatment of biological material to reduce waste, and will serve 15 municipalities containing around 55 260 inhabitants. The six municipal or sub-municipal sewage treatment plants will also feature new technology capable of breaking down waste into useful material. 

In addition, five existing sewage treatment plants will be modified in order to increase the capacity of treatment units.

Local citizens will directly benefit from work carried out in their neighbourhoods. In Avellino province, a new sewage purification system will be installed in the town of Atripalda, while in Ariano Irpino, new sewage schemes will be connected outside the old town. Urban drainage work will also take place in towns such as Casalbore, Castelbaronia, Monteforte Irpino and Sturno. 

In Benevento province, depollution of the north and south basin of the Isclero river will be carried out, along with the completion of municipal sewer networks. In Caserta province, the construction and purification of drainage works will take place in Riardo, while municipal sewage networks will be upgraded in many towns. 

Ensuring capacity 

The sewage work will involve the extension of around 60 km of existing sewage networks with a view to serving newly constructed urban settlements. Existing networks will be reorganised and some 28 km of old sewers extensively refurbished. The newly restored infrastructure will also be better equipped to cope with storm water flows and unexpected dramatic increases in water volumes.

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). 

Total investment and EU funding 

Total investment for the project “Risanamento Ambientale Corpi Idrici Superficiali delle Aree Interne” is    EUR 100 000 000, with the EU’s European Regional Development Fund contributing EUR 75 000 000 through the “Campania” Operational Programme for the 2007-2013 programming period.
