Hiram WWTP and Sewer System - Advanced Wastewater Treatment in Hiram, Ohio

Hiram WWTP and Sewer System is a municipal wastewater treatment facility located in Hiram, Portage County, Ohio. It serves a population of approximately 1,242 residents, providing advanced treatment to protect public health and the environment. The plant is part of the village's infrastructure, managed by local authorities. The facility operates with advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 757.08 cubic meters per day and a current discharge volume of 567.81 cubic meters per day, the plant operates below its capacity, indicating room for future growth. Under the U.S. Clean Water Act, such facilities are required to meet National Pollutant Discharge Elimination System (NPDES) permit limits to ensure water quality standards are upheld. The treated effluent from Hiram WWTP is discharged into a local stream that flows into the Mahoning River, part of the Ohio River basin. The Mahoning River supports diverse aquatic life and is an important water resource for the region. The plant's advanced treatment helps reduce nutrient loading, protecting downstream ecosystems and recreational uses.

The plant discharges into a tributary of the Mahoning River, which flows into the Ohio River and ultimately the Mississippi River system. The Mahoning River watershed supports a variety of fish and macroinvertebrate species, and its water quality is influenced by both urban and agricultural runoff. Advanced treatment at this plant helps mitigate nutrient pollution, which is critical for preventing algal blooms and maintaining dissolved oxygen levels in the receiving waters.
