Stendes nami NAI Muldu iela Wastewater Treatment Plant, Abavas pagasts, Latvia

Stendes nami NAI Muldu iela is a wastewater treatment plant located in Abavas pagasts, Talsu novads, Latvia. The facility serves a small population of 417 and operates with secondary treatment, which is the standard requirement under the EU Urban Waste Water Treatment Directive for agglomerations of this size. The plant has a designed capacity of 234.00 m³/day and currently discharges 79.59 m³/day of treated wastewater. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids, meeting the effluent quality standards set by Latvian regulations aligned with EU directives. The treated effluent is discharged into the local watershed, which ultimately drains into the Baltic Sea via the Irbe Strait. The plant plays a role in protecting the region's surface waters from nutrient pollution, supporting the ecological health of rivers and coastal waters in western Latvia.

The plant discharges into the Abava River basin, which flows into the Venta River and eventually reaches the Baltic Sea. The Baltic Sea is a brackish water body sensitive to eutrophication from nutrient inputs. The secondary treatment at this plant helps reduce organic load and nutrients, contributing to the protection of downstream aquatic ecosystems and coastal water quality.
