Overview
Merekodu reoveepuhasti is a closed advanced treatment plant in Vääna-Jõesuu küla, Estonia, serving 29 people. It discharged 6.68 m³/day of treated wastewater before closure.
Merekodu reoveepuhasti is a former wastewater treatment plant located in Vääna-Jõesuu küla, Harku vald, Harju maakond, Estonia. The plant served a small population of 29 people and was designed with a capacity of 370 m³/day, though it discharged only 6.68 m³/day before ceasing operations. The plant provided advanced treatment, which is a high level of purification. Under Estonian regulations, which align with the EU Urban Waste Water Treatment Directive (91/271/EEC), advanced treatment is typically required for sensitive areas. Although the plant is now closed, its advanced treatment level reflects the environmental sensitivity of the coastal region. The plant is located within 10 km of the Baltic Sea coast, making its discharge potentially impactful on the marine environment. The treated effluent likely drained into the Gulf of Finland, a part of the Baltic Sea, which is a brackish water body with limited water exchange and high ecological sensitivity.
Environmental context
The plant is situated near the Baltic Sea coast, within 10 km of the shoreline. The receiving water body is likely the Gulf of Finland, which is part of the Baltic Sea, a semi-enclosed sea with brackish water and vulnerable to nutrient pollution. The area supports diverse aquatic life and is an important migratory corridor for birds. The advanced treatment level suggests efforts to minimize nutrient and pollutant loads to this sensitive marine environment.
Frequently asked questions
Merekodu reoveepuhasti is located in Vääna-Jõesuu küla, Harku vald, Harju maakond, Estonia, near the Baltic Sea coast.
The plant provided advanced treatment, which is a high level of purification that removes nutrients and other pollutants beyond secondary treatment.
The plant discharged treated wastewater into the local environment, likely into the Gulf of Finland via a nearby watercourse, given its coastal location.
Estonian wastewater treatment plants operate under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection, treatment, and discharge based on population size and receiving water sensitivity.
The plant is listed as closed, which may be due to consolidation of wastewater services to a larger regional facility, as is common for small plants in sparsely populated areas.
