What Acque del Chiampo does

Acque del Chiampo S.p.A. Società Benefit is a publicly owned, concession-based integrated water utility serving the ATO Valle del Chiampo in Italy's Vicenza province. Founded in 1974 (re-incorporated as a Società Benefit in 2015), the company provides the integrated water service (potable water supply, sewage collection, and wastewater treatment) to over 100,000 residents across 13 municipalities and to approximately 124 industrial customers, principally tanneries in Italy's largest leather manufacturing district. Its headquarters are in Arzignano and it employs 51-100 staff.

The company's core technical asset is the Arzignano treatment plant, which manages over 1.633 million population equivalent of polluting load at 40,000 m³/day — the largest in Veneto and one of the most important globally for tannery effluent. Specialized capabilities include biological treatment of high-strength industrial wastewater, RADOX technology for PFAS microcontaminant degradation, and an in-house accredited laboratory (no. 00548, ISO/IEC 17025). Infrastructure includes 879 km of distribution network (undergoing NRRP-funded digitization), 39 km of dedicated HDPE industrial sewers, and three treatment plants. The company holds ISO 9001, 14001, 45001, UNI/PdR 125:2022 certifications plus DNV ESG Recognition.

Revenue is generated entirely through regulated ARERA tariffs for civil and industrial water services, plus ancillary fees (autospurgo, leak detection, meter reading). Tariffs are usage-based with annual billing. The company is wholly owned by 10 municipal shareholders, with Arzignano holding 52.31% and Chiampo 22.28%. Capital is raised via bond issuance on the ExtraMOT PRO market (including EUR 11.2M from Crédit Agricole Italia in May 2026) and co-financed by NRRP grants (EUR 12.4M across two projects) and tariff-funded capex.
