Kitakyushu City Hiagari Purification Center Administration Building (Visitor Center)

Clean Water, Protecting Our Future ― Learning About the Environment Through Sewage Systems

This facility protects Kitakyushu City's natural and living environments by purifying wastewater and discharging it into the sea, while also utilizing natural energy and effectively using sewerage resources. After learning about the facility overview and sewerage systems, visitors tour the premises.

The Hiagari Purification Center, designed as a combined sewer system, was completed and began operations in April 1970. Its current treatment capacity is 263,000 cubic meters per day. It treats sewage from Kokura Kita Ward, Tobata Ward, and parts of Kokura Minami Ward and Yahata Higashi Ward using the activated sludge process, discharging the treated effluent into the mouth of the Tōkai Bay.　

On April 23, 2015, the management building of the Hiagari Purification Center was renovated and reopened as a “Visitor Center,” serving as a new hub for sewerage and environmental learning.
