Overview
LAGNA wastewater treatment plant serves San Maurizio d'Opaglio in Piemonte, Italy, treating wastewater for approximately 5,352 people. The plant operates under Italy's implementation of the EU Urban Waste Water Treatment Directive.
LAGNA is a wastewater treatment plant located in San Maurizio d'Opaglio, in the Piemonte region of northern Italy. The facility serves a population of approximately 5,352 people, placing it in the small agglomeration category under EU regulations. It is situated in the subalpine zone near Lake Orta, an area known for its scenic and ecological value. As a plant serving fewer than 10,000 population equivalents, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC) requirements for appropriate treatment. Italian regulations transpose this directive, mandating secondary treatment or equivalent for discharges into freshwater bodies in sensitive areas. The regulatory framework ensures compliance with national standards. The treated effluent from LAGNA likely discharges into a local watercourse that flows into Lake Orta, a deep subalpine lake in the Po River basin. Lake Orta drains via the Nigoglia stream into the Toce River, which then joins the Po River and ultimately reaches the Adriatic Sea. The plant plays a role in protecting the lake's water quality and the downstream aquatic ecosystem.
Environmental context
LAGNA's treated wastewater discharges into a local tributary that flows into Lake Orta, a deep subalpine lake in the Po River basin. Lake Orta is ecologically sensitive, having experienced historical industrial pollution, and supports diverse aquatic life including endemic fish species. The lake drains via the Nigoglia stream into the Toce River, which joins the Po River and flows to the Adriatic Sea. Protecting this watershed is critical for maintaining water quality in the lake and downstream environments.
