What Abbanoa does

Abbanoa SpA is the sole manager of the Integrated Water Service (Servizio Idrico Integrato, SII) in Sardinia, Italy, operating under a regional concession granted by Egas (Ente di Governo dell'Ambito Idrico della Sardegna) within the national ARERA regulatory framework. The company manages the complete water cycle across the region, including drinking water potabilization and distribution through dams and treatment plants, sewage collection (fognatura), and wastewater purification (depurazione). Headquartered in Nuoro with operational offices in Cagliari, Olbia, Tempio Pausania, and other district locations, Abbanoa operates the physical water and sewage infrastructure spanning all of Sardinia. The company maintains a workforce of approximately 1,300 employees and conducts approximately 12,000 annual water quality sample tests covering roughly 315,000 chemical and bacteriological parameters.

Abbanoa's customer base spans four segments: residential individuals (Privato), commercial businesses (Impresa), condominiums (Condominio), and public entities and municipalities (Ente o Comune). The company generates revenue through regulated water tariffs covering three components — water supply, sewage, and treatment — determined by Egas in compliance with ARERA's national framework, billed on a monthly subscription basis. Customer service is delivered through a hybrid channel model including physical service points (sportelli), a 24/7 toll-free fault reporting line (800.022.040), customer service call center (800.062.692), the Sportello Online digital portal, and social media channels. The company also offers social tariff support through the Bonus Idrico Integrativo program for qualifying households.

The business model is that of a regulated natural monopoly: as the exclusive concession holder, Abbanoa faces no direct competition within its service area but is subject to tariff regulation and quality standards (ARERA Delib. 655/2015 contractual quality and 917/2017 technical quality). The company is currently executing a significant infrastructure modernization program funded substantially by PNRR (€42 million) and FSC sources across 15+ municipalities, alongside balance-sheet investments in network renewal. In April 2025, a new three-member Board of Directors took office under President Giuseppe Sardu, launching a major personnel reclassification and dispute resolution initiative. The company is privately held as a Società per Azioni (SpA) under Italian law, with regional public entities maintaining control consistent with the Italian multi-utility ownership model.
