Tradition and Innovation in Water Use and Reclamation
Of all the arts of food production, none is older or more important than irrigation. Historical and archaeological findings show that irrigation played a major role in the development...
Simplified Water Treatment Plant Design
The building of succeeding generations of sophisticated water and waste water plants, usually containing complex and energy intensive equipment, has been one of the marks of technically...
Cost-Effective Use of Municipal Wastewater Treatment Ponds
Treatment ponds are a cost-effective alternative for municipal wastewater treatment. When compared to other secondary treatment alternatives, ponds are generally the least costly, require...
Land Treatment Systems and the Environment
This paper summarizes the results from several experiments using the rapid infiltration, overland flow and slow infiltration modes of land treatment....
Systems of Waste Water Management in Europe
The history of European waste water management is briefly reviewed. Legal aspects of waste water management are presented by examples from Germany and Switzerland. International agreements...
The Place of Land Treatment of Wastewater in Today's Society
Land treatment of sewage can be a viable alternative to secondary and/or tertiary in-plant treatment. Depending on local conditions, overland-flow, low-rate, or high-rate systems, or a...
Earthquake Engineering and Soil Dynamics
The Conference on Earthquake Engineering and Soil Dynamics is the tenth in a series of Specialty Conferences sponsored by the ASCE Geotechnical Division (formerly the Soil Mechanics and...
European Water Treatment Practices�� Their Experience with Ozone
Today, more than 1100 water treatment plants worldwide use ozone for some purpose. In Europe, it is always regarded as a water-treatment technique and seldom simply as a disinfectant....
European Water Treatment Practices�� The Promise of Biological Activated Carbon
Bacterial growths occur in all granulated activated carbon columns. In fact, it is difficult to prevent such growths. The Germans now deliberately foster aerobic bacterial growth by providing...
Bypassing Sand at Coastal Inlets
To reduce dredging requirements and to provide calm navigation channels, the U.S. Corps of Engineers often constructs jetties and breakwaters. These structures block sand drifting along...
Foundation Soil Preload Saves $164,000
Soils in the lower Mississippi valley are highly compressible and present a challenge to structural foundation designers. Rather than support power plant structures on piles, one design...
EPA Proposes Far-Reaching Regulations for Reducing Synthetic Organics in Drinking Water
In late January, 1978, EPA proposed far-reaching regulations for reducing synthetic organic chemicals in drinking water, bringing about the most sweeping changes in the water-treatment...
Trench Cave-In: Contractor's Responsibility
The article Can Trench Cave-In Deaths Be Cut� in CIVIL ENGINEERING�ASCE, September 1977, states that the owner's engineer should accept responsibility for the design of temporary...
Major Cause of Earthquake Damage is Ground Failure
Ground failure is one of the most destructive effects of large earthquakes. For example, about 60% of the damage during the 1964 Alaska earthquake was a consequence of ground failure....
The Story Behind the New Clean Water Act of 1977
The Clean Water Act of 1977 keeps intact the basic principles of the strong Water Pollution Control Act (PL 92-500) of 1972. Because of the shear magnitude of upgrading the nation's...
U.K. Tunnelling Costs Halved by Use of Unbolted Concrete Lining Segments
Britain now has more than 25 years experience in the development of precast tunnel linings, for tunnels in clay. These linings are expanded directly against the ground. Under suitable...
Rouen, France Water Treatment Plant Using Biological Activated Carbon
The la Chapelle drinking water treatment plant in Rouen, France was designed specifically to incorporate biological activated carbon (BAC). With many U.S. cities faced with the prospect...
Sludge Pyrolysis: How Big a Future�
Pyrolysis is the destructive distillation of combustible elements by heat in the total absence of oxygen. Partial pyrolysis or starved air combustion is the gasification of a material...
Trans Alaska Pipeline
This is one of the most extraordinary projects contending for the OCEA awards. Examples: the 360 mile haul road built in one summer; the 29 construction camps, self-contained cities to...
Mill Expansion Increases Production by 50% and Drops Water Use by 90%
Armco's Kansas City steel works expansion is nominated for 1978 Outstanding Civil Engineering Achievement Award. Extensive provisions for air and water pollution control is...
