Flush tank mechanism from Tucson, Arizona, circa 1900-1925.
Flush tank mechanisms were installed in manholes, primarily at the upstream
terminal ends of sewage mains, to facilitate the periodic flushing of
the downstream mains. This approach was utilized in the early years of
the design and installation of sanitary-sewage-only conveyance systems,
when manholes were not utilized to the extent they are now, and where
certain reaches of sewer had an unfavorable combination of low slope and
tributary sewage flow. The public potable water system was routinely the
source of the water. Some of the devices were somewhat automatic; others
(such as the one on exhibit here) required a crew to trigger the flush.
In the Tucson metropolitan area system, over 200 flush tanks (of varying design) were installed. All are now out of service, and the involved water connections physically cut off. Source: The public sanitary sewage conveyance system serving the greater Tucson metropolitan area. |
