Hubbell-Southfield CSO RTB

Gazing upon the Hubbell-Southfield CSO RTB, one might not initially grasp its vital role. This structure isn’t just a concrete monolith. It’s a key player in Detroit’s fight against water pollution. The Hubbell-Southfield Combined Sewer Overflow Basin, or RTB, stands as a testament to engineering ingenuity. It tackles a significant challenge: combined sewer overflows. These overflows, a mix of sewage and stormwater, can pollute rivers during heavy rain. The Hubbell-Southfield CSO RTB intercepts these overflows. It treats a staggering 22 million gallons, preventing them from reaching the Rouge River. This basin isn’t just large; it’s smart. It operates in three different modes, maximizing its effectiveness. A unique shunt channel, initially used during construction, now plays a critical role in basin operations. This channel diverts excess flow, preventing the basin from overloading and ensuring consistent treatment. Another innovative feature is its decanting capability. If the Detroit Wastewater Treatment Plant can’t handle the volume, the basin can release the top layer of treated water. This allows it to continue processing subsequent rainfall. The Hubbell-Southfield CSO RTB represents a collaborative effort. The Michigan Department of Environmental Quality worked closely with the Detroit Water and Sewerage Department throughout the project. This partnership ensured the basin’s effectiveness and innovative design. The Hubbell-Southfield CSO RTB is more than just a functional structure. It signifies Detroit’s dedication to a cleaner Rouge River. It showcases how innovative engineering solutions can protect our environment. It’s a silent guardian, working tirelessly to safeguard our waterways.
