Book excerpt: Excerpt from Rainfall, Water Supply, Waterways of the United States When water is made to flow through a layer of sodium permutit, the latter exchanges its soda for the calcium and magnesium salts of the water and the degree of hardness in the latter is reduced to zero. The permutit has to be regenerated as it grows lax in action. This is easily accomplished by washing it for a few hours with a solution of common salt. Man ganese permutit in connection with marble dust removes all iron and acids from waters thus affected. The practice of softening the entire water supply of a municipality has grown steadily and in not a few large manufacturing cities the municipal softening plant is saving the citi zens hundreds of thousands of tons of coal per annum and adding years of life to the community's boilers. The principal require ments are (1) mixing chambers, in which the softening chemicals are thoroughly mixed with the water; (2) capacious settling basins suffi cient to give the necessary time for the slower reactions when the temperature is low, as in winter; (3) a device for adding a coagulant (alum or ferrous sulphate) at both the en trance port and the exit port of the water into and from the settling basins, (4) substantial mechanical filters. In addition, as one of the requisites should be a special apparatus to slake the lime, reduce it to a proper emulsion and feed it in proper quantity automatically into the flowing water. At the municipal water softening plant at Cleveland, Ohio, 000 gallons of water per day require the daily application of 40 tons of quicklime. This is slaked with hot water, mixed into an emulsion in an agitator, taken to tanks where it is cooled and diluted to the proper consistency and finally pumped at a uniform rate into the flowing water.

Download or read book Water Follies written by Robert Jerome Glennon and published by Island Press. This book was released on 2012-09-26 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Santa Cruz River that once flowed through Tucson, Arizona is today a sad mirage of a river. Except for brief periods following heavy rainfall, it is bone dry. The cottonwood and willow trees that once lined its banks have died, and the profusion of birds and wildlife recorded by early settlers are nowhere to be seen. The river is dead. What happened? Where did the water go. As Robert Glennon explains in Water Follies, what killed the Santa Cruz River -- and could devastate other surface waters across the United States -- was groundwater pumping. From 1940 to 2000, the volume of water drawn annually from underground aquifers in Tucson jumped more than six-fold, from 50,000 to 330,000 acre-feet per year. And Tucson is hardly an exception -- similar increases in groundwater pumping have occurred across the country and around the world. In a striking collection of stories that bring to life the human and natural consequences of our growing national thirst, Robert Glennon provides an occasionally wry and always fascinating account of groundwater pumping and the environmental problems it causes. Robert Glennon sketches the culture of water use in the United States, explaining how and why we are growing increasingly reliant on groundwater. He uses the examples of the Santa Cruz and San Pedro rivers in Arizona to illustrate the science of hydrology and the legal aspects of water use and conflicts. Following that, he offers a dozen stories -- ranging from Down East Maine to San Antonio's River Walk to Atlanta's burgeoning suburbs -- that clearly illustrate the array of problems caused by groundwater pumping. Each episode poses a conflict of values that reveals the complexity of how and why we use water. These poignant and sometimes perverse tales tell of human foibles including greed, stubbornness, and, especially, the unlimited human capacity to ignore reality. As Robert Glennon explores the folly of our actions and the laws governing them, he suggests common-sense legal and policy reforms that could help avert potentially catastrophic future effects. Water Follies, the first book to focus on the impact of groundwater pumping on the environment, brings this widespread but underappreciated problem to the attention of citizens and communities across America.

This book was released on 2014-09-14 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the technological developments relevant to water supply and wastewater date back to more than to five thousand years ago. These developments were driven by the necessity to make efficient use of natural resources, to make civilizations more resistant to destructive natural elements, and to improve the standards of life, both at public and private level. Rapid technological progress in the 20th century created a disregard for past sanitation and wastewater and stormwater technologies that were considered to be far behind the present ones. A great deal of unresolved problems in the developing world related to the wastewater management principles, such as the decentralization of the processes, the durability of the water projects, the cost effectiveness, and sustainability issues, such as protection from floods and droughts were intensified to an unprecedented degree. New problems have arisen such as the contamination of surface and groundwater. Naturally, intensification of unresolved problems has led to the reconsideration of successful past achievements. This retrospective view, based on archaeological, historical, and technical evidence, has shown two things: the similarity of physicochemical and biological principles with the present ones and the advanced level of wastewater engineering and management practices. Evolution of Sanitation and Wastewater Technologies through the Centuries presents and discusses the major achievements in the scientific fields of sanitation and hygienic water use systems throughout the millennia, and compares the water technological developments in several civilizations. It provides valuable insights into ancient wastewater and stormwater management technologies with their apparent characteristics of durability, adaptability to the environment, and sustainability. These technologies are the underpinning of modern achievements in sanitary engineering and wastewater management practices. It is the best proof that “the past is the key for the future”. Evolution of Sanitation and Wastewater Technologies through the Centuries is a textbook for undergraduate and graduate courses of Water Resources, Civil Engineering, Hydraulics, Ancient History, Archaeology, Environmental Management and is also a valuable resource for all researchers in the these fields.

Book excerpt: “Wonderfully written…Mr. Owen writes about water, but in these polarized times the lessons he shares spill into other arenas. The world of water rights and wrongs along the Colorado River offers hope for other problems.” —Wall Street Journal An eye-opening account of where our water comes from and where it all goes. The Colorado River is an essential resource for a surprisingly large part of the United States, and every gallon that flows down it is owned or claimed by someone. David Owen traces all that water from the Colorado’s headwaters to its parched terminus, once a verdant wetland but now a million-acre desert. He takes readers on an adventure downriver, along a labyrinth of waterways, reservoirs, power plants, farms, fracking sites, ghost towns, and RV parks, to the spot near the U.S.–Mexico border where the river runs dry. Water problems in the western United States can seem tantalizingly easy to solve: just turn off the fountains at the Bellagio, stop selling hay to China, ban golf, cut down the almond trees, and kill all the lawyers. But a closer look reveals a vast man-made ecosystem that is far more complex and more interesting than the headlines let on. The story Owen tells in Where the Water Goes is crucial to our future: how a patchwork of engineering marvels, byzantine legal agreements, aging infrastructure, and neighborly cooperation enables life to flourish in the desert—and the disastrous consequences we face when any part of this tenuous system fails.

This book was released on 1998-12-08 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Society today may be more vulnerable to global-scale, long-term, climate change than ever before. Even without any human influence, past records show that climate can be expected to continue to undergo considerable change over decades to centuries. Measures for adaption and mitigation will call for policy decisions based on a sound scientific foundation. Better understanding and prediction of climate variations can be achieved most efficiently through a nationally recognized "dec-cen" science plan. This book articulates the scientific issues that must be addressed to advance us efficiently toward that understanding and outlines the data collection and modeling needed.

Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
