Plumbing the Quality of a Sewer System
Consultants in Phoenix were recently charged with assessing the city's sewer system, many feet of which were laid without plastic lining to protect them. Developing a capital...

Leaking Plumbing Fixtures and Water Conservation

Low Flush Plumbing Fixtures and Wastewater Systems
The significance of low flush plumbing fixtures on the wastewater collection and treatment system serving a small community has been determined. Among the concerns studied were: functional...

The Water and Waste Water Savings Achieved by Ultra Low Flush Toilets in Santa Monica, California

Underground Oil Lens Management at John F. Kennedy International Airport
Observation wells plumbed using a water surface detector and standard topographic interpolation techniques were used to establish the hydraulic gradient of the groundwater and the presence...

You Need More Than a Plumber's Helper
Maintenance of subsurface drains may be the least understood and most neglected of all maintenance activities carried out by irrigation districts. Few irrigation districts have a maintenance...

Vacuum Sewers — the Future for Sewage Collection—
Patented in the 19th Century, vacuum sewers are making a comeback. Vacuum is created and maintained at a central collection station and extended, through a network of collecting pipes,...

Structural Out-of-Plumbs

Study of In-Service Bitumenized Fiber Sewer Pipe
According to the Plumbing Bureau of the City of Tampa, from 1967 to 1973, over 2,000 bitumenized fiber sewer pipe failures occurred in the City of Tampa. This project involved the recovery...

Deformation Measurements of Flaming Gorge Dam
The structural action and accuracy of assumptions used for design of concrete dams can be investigated best by structural behavior tests of dams in service. Instruments to indicate length...

Evaluation of Accuracy of Precise Leveling
Three sources of errors in precise leveling are described: (1) Errors due to rod readings by estimation to 0.10 of the rod division and with the aid of a planoparallel micrometer; (2)...

Measuring Structural Behavior of Glen Canyon Dam
This paper describes layouts of two systems and the methods used for measuring the deformation of Glen Canyon Dam, a large, concrete, arch structure. The deformation is caused by water...

Geodesy and the Torsion Balance
In the past the Eötvös torsion balance has been used only in commercial geophysical explorations and not for geodetic purposes. Even in geophysics, after approximately 30 yrs of use, it...
