Overview
Kehra reoveepuhasti is an advanced wastewater treatment plant serving Kehra linn, Estonia. It treats wastewater for a population of 2,020 with a designed capacity of 4,500 m³/day.
Kehra reoveepuhasti is an advanced wastewater treatment plant located in Kehra linn, Harju County, Estonia. The facility serves a population of approximately 2,020 residents, making it a small-scale municipal treatment plant within the country's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,500 m³/day and a reported discharge volume of 465.41 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. As an Estonian facility, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment based on agglomeration size. The treated effluent is discharged into a local water body, contributing to the protection of the surrounding watershed. The plant's location within 50 km of the Baltic Sea coast means that its discharges ultimately influence the marine environment, making effective nutrient removal critical for preventing eutrophication in coastal waters.
Environmental context
The plant discharges into a local watercourse that drains into the Baltic Sea via the Gulf of Finland. The Baltic Sea is a brackish, semi-enclosed sea with limited water exchange, making it highly sensitive to nutrient pollution. Advanced treatment at this plant helps reduce nitrogen and phosphorus loads, supporting the ecological health of downstream rivers and coastal ecosystems.
