The tunnel lies at a depth of about m and has a capacity of holding 70 million gallons of combined storm water and wastewater. The project primarily involved the construction of a storage tunnel to reduce the combined sewage overflows into Lake Erie and Euclid Creek during heavy rains.
It is capable of holding 70 million gallons of combined stormwater and wastewater. Euclid Creek storage tunnel is the second tunnel out of the seven tunnels to be constructed under the Project Clean Lake programme. Cleveland witnesses urban flooding and overflow of sewage into Lake Erie and Euclid Creek during heavy rains. The sewers in the city, which were constructed in the 19th century, convey sewage and rainwater in a single pipe became inadequate.
Combined sewage overflows that occur in Euclid Creek about 60 times a year necessitated the construction of a new tunnel. The sewerage overflows collected and stored in the tunnel are pumped out and conveyed for treatment to the Easterly Wastewater Treatment Plant that currently serves approximately , residents. It further stretches under Lake Erie at a depth of 3,ft, pass under the shoreline near Green Creek in East nd, head eastward to Nottingham Road and end at St.
Clair Avenue. The storage tunnel measures 3. The tunnel was bored using a tunnel boring machine TBM named Mackenzie. The TBM measures t in length and weighs 1,t. The cutter head of the machine alone weighs approximately ,lbs, comprising 52 steel disks. By the mids, however, this tunnel, and a second, larger one later built to the same crib, became inadequate, as pollution of the river and lake had worsened considerably. Therefore, in , the city undertook to construct a new tunnel leading to a new water intake crib three miles out in the lake.
Still visible from Cleveland's shoreline today, this crib eventually became known as the 5-mile crib, because, while located three miles from the shore, its tunnel stretches a distance of five miles to the east side Kirtland pumping station. The project was completed in , but by , with questions raised regarding the new tunnel's integrity and a rising typhoid fever rate in the city, plans were soon made to construct a fourth tunnel--larger in diameter and extending further out into the lake than any of the previous ones.
The new tunnel would be constructed from the old west side crib--abandoned when construction of the new tunnel to the Kirtland station had been completed, to a new water intake crib nearly four miles out into the lake. Construction of this newest lake tunnel began in March It was initially lauded for its safety record, especially when compared to that of the last tunnel's construction, which had taken the lives of a total of 33 workers in four separate accidents occurring between But the praise quickly ended on July 25, , when Clevelanders woke up to learn that there had been a terrible accident the night before in the tunnel.
In the evening hours of July 24, Harry Vokes, a year old Case Institute graduate, who was serving as acting foreman, led a work crew of eight men, including John Patton, down into the tunnel from the new crib known as Crib No.
Shortly thereafter, when natural gas vented up from the lake bed and somehow ignited, an explosion occurred, which buried Vokes and his entire work crew under hundreds of feet of mud and tunnel debris. As often happens in the midst of tragedy, a number of men, including African American Garrett Morgan, inventor of a new type of gas mask, and later of other patented products including the first 3-position traffic signal light, exhibited extreme courage and bravery in descending into the tunnel to search for survivors that night and the following morning.
The first two rescue attempts led by Crib superintendent John Johnston and Construction superintendent Gus Van Duzen rescued none of the work crew and resulted only in the deaths of ten of the rescuers who were overcome by the gas in the tunnel. Several additional efforts in the early morning hours of September 25 by Van Duzen's stepson Tom Clancy resulted in the successful rescue of one or two members of the second rescue team lying unconscious on the tunnel floor, but it was not until Morgan, and his brother Frank, arrived with their gas masks that they, tunnel workers, firefighters and others at Crib No.
Once all of the rescuers, alive or dead, were removed from the tunnel, sandhogs began to dig through the mud, and sometimes patiently wait for gas in the tunnel to dissipate, in a renewed effort to reach and retrieve the bodies of the work crew. As this was slowly progressing, Cleveland City Hall launched a probe to determine who was at fault for this disaster. Fingers were initially pointed at Van Duzen, Johnston and Vokes, as well as at a city chemist who had failed to timely test an air sample from the tunnel.
But, when witnesses began to fault city officials for safety shortcomings at Crib No. Davis quickly ended the probe, concluding that no one was at fault and that "every man did what he thought best.
By August 21, all nine bodies were recovered, including that of John Patton.
