About the Event

In some cities, including Rome, Istanbul (Constantinople), and Fustat, networked ancient sewer systems continue to function today as collection systems for those cities’ modernized sewer systems. Instead of the sewerage flowing to a river or the sea, the pipes have been re-routed to modern sewer treatment facilities. As cities grew in the 19th century, increasing concerns were raised about public health due to outbreaks of diseases such as typhoid and cholera. To help control these outbreaks, the development of municipal sanitation programs occurred in the late 19th and 20thcenturies that consisted of the construction of extensive sewer systems. The operation and construction of these systems continue today with little maintenance, replacement and/or renovation. In the 1980’s, inspection techniques and pipe condition rating systems were developed in the United Kingdom to determine, for the first time, the condition and state of these critical sewerage pipelines that have been in service for over 100 years with no maintenance and or repair. Since many of these pipelines were found to be in a state of failure and open cut replacement was not a practical or financially feasible option in densely populated and crowded urban cities, new trenchless pipeline renovations methods such as Cured-In-Place Pipe (CIPP) liners were developed and commercialized to build a new pipe within the old pipe.
