Operation of The Aqueduct
For the 180 years of the aqueduct's use, from AD 80 to 260, the aqueduct required constant maintenance, improvement, cleaning, and freeing from limestone accretions. Maintenance was facilitated by regular maintenance shafts, through which a worker could descend into the aqueduct. Additional maintenance shafts were built at the sites of repairs and at the boundaries between building segments. There were also open pools at points where various springs ran together so that maintenance personnel could keep an eye on problem areas.
