Monte Sant'Angelo A Wastewater Treatment Plant, Puglia, Italy

Monte Sant'Angelo A is a municipal wastewater treatment plant located in the town of Monte Sant'Angelo, in the province of Foggia, Puglia, Italy. The facility serves a population of approximately 5,774 residents and is situated in the Gargano Promontory, a coastal area of the Adriatic Sea. The plant's location within 10 kilometers of the coast places it in a sensitive coastal zone requiring careful management of treated effluent. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into coastal waters. The designed capacity of 11,750 cubic meters per day indicates the plant is sized to handle peak flows, with current discharge volumes around 822 cubic meters per day. As a secondary treatment facility, it uses biological processes to reduce organic matter and suspended solids before discharge. The treated effluent from Monte Sant'Angelo A ultimately reaches the Adriatic Sea, a semi-enclosed sea that supports diverse marine ecosystems, including seagrass meadows and fish nurseries. The Gargano coast is ecologically sensitive, with important habitats for migratory birds and marine species. Proper treatment helps protect water quality in the coastal zone, supporting tourism and fisheries that are vital to the local economy.

The plant discharges into the Adriatic Sea via local watercourses in the Gargano Peninsula. The Adriatic Sea is a shallow, semi-enclosed basin with limited water exchange, making it vulnerable to nutrient pollution. The coastal waters near Monte Sant'Angelo support seagrass beds and marine biodiversity, including species of conservation concern. Effective secondary treatment reduces organic load and nutrients, helping to prevent eutrophication and maintain the ecological health of this coastal environment.
