Privatization and Water Supply/Treatment Projects
Privatization is often mentioned as a way to get much needed, but difficult to finance infrastructure projects delivered for both developed and developing countries. However, the suitability...
From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...
Cleaning Up Clay
Using soil vapor extraction to remove volatile organic compounds from ground water and unsaturated soils can achieve faster and more-complete cleanups than conventional pump-and-treat...
Visualizing the Flow
Digital modeling of passive cooling techniques now enables engineers to create comfortable environments in even the most unlikely of spaces�including glass atriums in the desert. Passive...

19 Tough Acts to Follow
The nominations for this year's Outstanding Civil Engineering Achievement Award included everything from runway extensions to highway extensions, water fun parks to water...
Back to Bacteria: A More Natural Filtration
Drinking-water treatment used to be simple: use the best source available, filter if turbidity is present and add plenty of chlorine. Typically, these are the barriers that guard against...
Management of Water Treatment Plant Residuals
Potable water treatment processes produce safe drinking water and generate a wide variety of waste products known as residuals, including organic and inorganic compounds in liquid, solid,...
North American Water and Environment Congress & Destructive Water
This proceedings contains papers presented at the North American Water and Environment Congress '96 of the ASCE's Environmental Engineering Division, Water Resources...
Washington Buildup
Despite its reputation as a city mired in fiscal crisis, Washington, D. C., continues to improve its basic infrastructure. A look at three ongoing projects�a sports arena, a waste water...
Pump and Treat and Wait (Available only in the Geo/Environmental Special Issue)
Pump and treat, a common ground-water cleanup technique, is slow to clean up deep contaminated aquifers. Adaptive intermittent pumping can increase the cleanup rate�and decrease costs�by...
Earth Reinforcement and Soil Structures
Few subjects in recent years have raised the general interest and imagination of the Civil Engineering profession as the concept of reinforcing soil. The basic simplicity of the principles...
Water Quality Regs: Staying Ahead
After a century in which water utilities could stay well ahead of most regulations simply by being responsible, professional organizations, they now seem to be playing catchup in a game...
Residual Benefits
Stringent pretreatment and effluent standards and a lack of capacity prohibit their release into sanitary sewer systems. Landfill disposal is costly. The National Pollutant Discharge Elimination...
Soft Ground Not Easy Ground for TBM
The King County Department of Metropolitan Services (formerly called Metro), faced with the need to transfer wastewater from the West Seattle drainage basin to a secondary treatment plant...
Greening of Ground Water
As many as 69 different organic compounds and 24 metal species can be found in ground water underlying the 85 acre Bofors-Nobel Superfund site in Muskegon County, Mich., a testimony to...
Toxic Air Emissions from Wastewater Treatment Facilities
The Magnificent 17
Only two of 1995's record 19 nominees could win the 1995 Outstanding Civil Engineering Achievement Award and the Award of Merit, but the 17 remaining nominees are noteworthy...
Turning Water into Dollars
Revenues were suffering in the water departments of Jefferson Parish, La. and Houston in the late 1980s and early 90s. But after overhauling their billing, collection and customer-service...
Beware the Sediment Scare
Your municipal or industrial stormwater facility meets best management practices (BMPs) as outlined by EPA. It is designed to meet requirements under the Clean Water Act and the accompanying...
