Hissmofors avloppsreningsverk is a wastewater treatment facility located in the Hissmofors area of Krokom, within Krokoms kommun, Jämtlands län, Sweden. The plant serves a population of 2,115 and operates with advanced treatment processes, ensuring high-quality effluent standards. The plant's designed capacity is 6,500 cubic meters per day, with an actual discharge volume of 332.02 cubic meters, indicating ample capacity for current loads. As a Swedish facility, it operates under national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and secondary treatment for all discharges. The treated effluent is discharged into the local watershed, which ultimately drains into the Indalsälven river system and then into the Baltic Sea. The plant plays a key role in protecting the water quality of the surrounding rivers and the downstream aquatic environment, supporting biodiversity and recreational use.

The plant discharges into the Indalsälven river basin, which flows through Jämtland and Västernorrland before reaching the Baltic Sea. This watershed supports diverse aquatic life, including salmon and trout populations, and is important for local fishing and recreation. The advanced treatment helps minimize nutrient loading and protects the sensitive downstream ecosystems.
