Over two days, Taylor and his daughter Diana produced and posted 27 video interviews on the sister website Powder and Bulk Dot Com. This online video first almost took place last year right here on the popular video sharing site at Water and Wastewater Dot Com, but a nervous show manager stopped the camera at the last minute. Joe Taylor reports he is working on getting clearances from the major water and wastewater shows. In the near future you’ll likely be seeing live show videos from events such as the WEFTEC show or the AWWA annual meeting, ACE08. In the meantime I thought you’d like this preview of what you can expect by taking a look at some of the best videos from PTX South. This is a dry materials handling industry show where you’ll find some of the same equipment makers that you're familiar with. I think you'll find the handheld camerawork by Diana Taylor has an authentic indie film feel that is perfectly in tune with the growing online video medium. I found the best in-booth interviews involved a demonstration of some new piece of equipment. Even for those who attended the show, it’s worth the time to take a look at these unrehearsed live demos, with their up-close views and the opportunity to replay the action as many times as you want. Following are a few brief samples of some of the videos Joe Taylor said he found of interest:
On a visit to the Young Industries booth, Joe Taylor interviews James Mothersbaugh , who demonstrates a cohesive powder feeder that uses air pressure. Young Industries provides solutions in pneumatic conveying, mixing, blending, size reduction, and air pollution control. In his interview with Jack Paddock of Atlantic Coast Crushers (see lead photo), we learn that the company posts videos of their customer material tests on a private page on Yahoo! Taylor told me you can do the same on Powder and Bulk Dot Com. When you upload a video to this site, the default is for the video to be “public.” During your video upload, simply select the “private” button. You can then email the video page address to those with whom you want to share your private video.
You can find all 27 videos in the "Trade Shows and Events" channel in the Powder and Bulk Dot Com Video Center Don Dunnington

There are many potential demands on Colorado's remaining water, unbridled growth in some communities, agriculture, renewable energy, potential oil shale development, recreation, oil and gas and the water requirements traditional from coal fired generation. All are contributing to future shortage forecasts. For farmers along the South Platte River and Republican River more well shutdowns loomed while the San Luis Valley hoped to avoid involuntary shutdowns with engineering and cooperation. Coloradans started planning for a possible call on the Colorado River from the lower basin states. Douglas County started looking at collecting rainwater for sprinkling needs. We mourned the passing of Anthony Williams, W.D. Farr, Bob Hite and John D. Brown. Nolan Doesken won a 2007 Environmental Hero award from the NOAA for founding the Community Collaborative Rain, Hail and Snow Network. |

Residents in eight of this region’s 19 districts are drinking and cooking with groundwater contaminated with naturally occurring, highly toxic arsenic. Tasteless and colorless, the arsenic has slowly seeped into their water sources and then into their bodies. The result: chronic arsenic poisoning of hundreds of thousands of West Bengalis, with many more at risk. Thankfully, village-by-village, simple, locally developed solutions are making a change for the better. These solutions are providing much more than safe water. They are empowering communities and contributing to local economies by creating new business and job opportunities. Where did the arsenic come from? Arsenic is a naturally occurring semi-metallic compound found in groundwater around the world—including those in Bangladesh, Taiwan, Japan, Mexico, parts of the United States and India. Some argue that the increasing occurrence of arsenic in groundwater might be the result of the rapid and significant drawdown of aquifers as we struggle to meet our water demands. While arsenic may be tasteless and odorless, the human impact is deadly evident. Early indications appear in the form of dark spots on the chest, back, limbs and gums; then in the more advanced stages, wart-like skin eruptions on the hands, feet, and torso. Continuing exposure can result in enlargement of the liver, kidneys, and spleen, developing into malignant tumors and even disorders of the gastrointestinal, circulatory, and nervous systems. The arsenic problem hasn’t always been present in West Bengal. It is actually the result of efforts to solve microbiological contamination of surface water during the 1970s and 1980s when tube wells were installed throughout the region. The switch to groundwater came with a deadly price and awareness of the issue was slow to come. Because of the extreme poverty of the region, affected people often hesitated to seek medical care. By then, the damage was done. It was in the late 1980s that scientists began to find evidence of arsenic contamination in the groundwater, and by the 1990s the extent of the health impact became widely known. Partnering for simple, locally developed sustainable solutions
After pursuing a number of options, the university developed a simple arsenic-removal filter for use at community wellheads, incorporating activated alumina. The wellhead unit consists of a 12-inch diameter, seven-foot, two-inch-tall stainless steel column. Water flows through a 51-inch layer of activated alumina and then through an eight-inch layer of gravel. Every eight to 12 months the filter media is regenerated and the waste safely contained. One wellhead unit can serve up to 300 families and is expected to last for 10 to 15 years, with little maintenance required. The filter incorporates a simple, highly effective technology, is locally manufactured, easy to operate (no electricity required), easy to maintain, and relatively inexpensive—approximately $2,000 for each wellhead unit. Most important, the technology is sustainable, offering effective protection for years to come. Working with the local villages, water committees were formed to help implement the installations and encourage ongoing local input and control. To date, Water For People has helped finance the installation of 110 of these units providing safe, arsenic-free water for more than 33,000 people in multiple villages across West Bengal. Healthy results In villages where wellhead units have been installed, the incidence of arsenic poisoning has dropped dramatically. People are reporting living healthier and more productive lives. The difference according to one woman indicates a variety of positive changes. “I used to have indigestion and chronic dysentery. Now all these problems are gone, and I have an appetite. I used to spend 150 rupees (US$3.43) each month on medicine, and now I save this money.” Sustainable solutions that provide safe water and economic opportunity. Dipak Das churns the pedals of his three-wheeled bike earnestly, eyes straight ahead. He’s focused on safely navigating the endless maze of bumps, holes, oncoming traffic, pedestrians, and blowing dust. Immediately behind him packed tightly on the flat platform that’s wedged between the two rear wheels rest 20-or-so jiggling jugs of his most precious cargo—safe, filtered arsenic-free drinking water from the wellhead. Dipak delivers filtered water to 45 families that depend on the arsenic-free water he delivers. The 2,800 rupees (US $70) he earns each month is a good living by Indian standards. Before, he ran a roadside tea shop, worked longer hours and made less money. Now, his deliveries require only four hours a day giving him time to pursue other business opportunities. For Nirmal De and his family, their sole source of income is work that is related to the arsenic filter in Daharthuba Village, where they live. He used to work in a plastic toy factory that has since closed. He started out by delivering water to three families. Now that has grown to 50. On every delivery he attempts to sell the service to other families along his route. Sumitra, his wife, is the paid caretaker for the filter. She spends four hours every morning and three hours every evening operating the pump. She must periodically backwash the filter to ensure its effectiveness. She also keeps the platform clean throughout the day. The pump station has become the center of the community and even has a television to entertain women as they wait. Sumitra tries to make sure that women don’t get too absorbed in their television viewing and lose their place in line. Their older son, Sudip, also helps out at the filtration station and with deliveries. Besides the water delivery, a variety of other business enterprises often emerge around the arsenic filters. There are vendors who sell jerry cans for carrying the water. Others sell food and snacks at the wellhead. And at every station, an individual—like Sumitra—earns a salary to collect and record water payments from villagers. Day-by-day, village-by-village Water For People makes it a point to support our partners in West Bengal, who in turn work closely with communities. The goal is to obtain commitment to each project from community members, enabling them to take ownership of its long-term operation. In 2006, Water for People opened an office in Kolkata with a full-time country coordinator, Rajashi Mukherjee, to facilitate the work in the region. In the second most populous country in the world, Water For People is committed to help meet the most basic water and sanitation needs of thousands of India’s poorest. By partnering with local government entities, nongovernmental organizations, the local private sector and others, success will come, day-by-day, village-by-village. by David Stevenson About Water For People Founded in 1991, Water For People is a Denver-based private, nonprofit international development organization that supports safe drinking water and sanitation projects in developing countries. Water For People partners with communities and other nongovernmental organizations to help people improve their quality of life by supporting sustainable drinking water, sanitation, and health and hygiene projects.

Water Sustainability: A Looming Global Challenge |

We live in a rapidly changing world in which many of our expectations about natural resources may no longer be met. The seeming abundance of safe, low-cost water may falsely lead us to assume perpetual easy access to all the low-cost, high-quality water we want, when we want it. The water industry today must examine these assumptions. Although water covers 70 percent of our planet’s surface, less than one-half percent is freshwater available for our use. Most of our planet’s water is in oceans and too salty for many uses. Much of the remainder is locked in frozen glaciers, is remote from population centers or circulating in our atmosphere. So this seemingly abundant resource is actually quite constrained. What’s changing? Three factors are having an impact on our freshwater resources: Population growth – The world’s population is 6.6 billion and growing. As a result, humans are demanding more of the earth’s resources to sustain life and economic activity. Science and engineering have been developing and implementing technologies to alleviate some of this burden. However, there is a limit beyond which little can be done. It appears probable that we are nearing this limit. Economic growth – Economic growth in water scarce regions increases water demand. Last year the planet’s urban population exceeded the rural population for the first time in history. Fifty percent of the world’s population resides in metropolitan areas, increasing demands on water systems. Climate change – Planning and design criteria based on historic records may no longer be applicable in a world where water resources are heavily impacted by drought, flooding and/or an increase in mean sea level. As a result, facilities may be found to be at significant risk in the face of rapid climate change. Then and now Previous generations had the luxury of the earth’s excess natural “bio-capacity.” The capacity of the natural systems and cycles that renew our “wastes” and enable the conditions to support our human and ecological environments was far greater than the demands of the world’s population. Currently, however, the growing demand for earth’s natural resources, like water, is creating an imbalance between the earth’s bio-capacity and its inhabitants’ desired standard of living. The problem is the location, timing and distribution of rainfall. Our industry’s challenge is to help communities ensure that water is always where we need it, when we need it, which is not necessarily where it falls to the earth as rain. Water, water everywhere, but… Competition for available water is increasing because water is not distributed evenly over the globe. Nine countries possess 60 percent of the world’s available fresh water: Brazil, Russia, China, Canada, Indonesia, the United States, India, Columbia and the Democratic Republic of Congo. However, local variations of population distribution and freshwater supply are highly significant. Many communities, once water-rich, are facing a new challenge as water supply and demand are now imbalanced. In most European cities with more than 100,000 people, groundwater is being used at a faster rate than it can be replenished. Available water costs more and more to capture or draw from aquifers. Large cities like Mexico City, Bangkok, Manila, Beijing, Madras and Shanghai have experienced significant aquifer drops of between 10 to 50 meters. Other water scarcity examples include the Yangtze River Basin in China; Australia, now in its 10th year of a record drought; the Colorado River basin, also in the midst of a long-term drought of historic proportions; and parts of the Southeast United States, especially northern Georgia. Droughts or increased flooding may not be the only unfortunate consequence of changing rainfall patterns. These changes may also result in storm sewers and drainage systems that are inadequate to handle current and future needs because they were built on past assumptions that may now be invalid. Preparing for an uncertain future We are moving from what has been viewed as a time of certainty within our industry to a time of great uncertainty; we’re being driven by the forces of change in our climate – and in the water business. The challenge for key global water industry players, like Black & Veatch, and for our clients around the globe is to develop and implement sustainable solutions that will better manage the entire water cycle and help their customers and communities prepare for an uncertain future. These solutions will focus on how best to protect water at its source, treat it to the highest standards, deliver it to homes and businesses, and then collect and again treat the wastewater before reintroducing it safely back into the environment. We also seek methods of sourcing “new water” through reuse, aquifer storage and recovery or desalination of water, for example. Political leaders at all levels and the general public want to know what their utility leaders are doing to prepare for these challenges. They realize that water suppliers, regulators and customers can’t simply discuss or debate the future as it arrives; they must plan and take action today to minimize uncertainty and risk. All stakeholders must work together to craft robust long-term strategies and implement cost-effective solutions for mitigating and, if necessary, adapting to the potential impacts of climate change. Taking the long view The water industry must focus on the long view when facing the challenges of rapid population and economic growth, along with supply deficiencies or wet weather problems. And added to those trends are other pressing issues, like aging water infrastructure, degradation of water quality, changes in water rights and tightening regulations. That’s why Black & Veatch and other leaders in the global water industry are working to develop innovative solutions to address climate change, water scarcity and sustainability planning. We are seeking triple-bottom-line solutions that meet our clients’ social, economic and environmental goals; are sustainable; and are politically and commercially viable. Just as in the 1990s, when decision making shifted from capital costs to life-cycle costs, now in the early part of this century, the importance of triple-bottom-line decision making is being recognized and emphasized during all stages of planning. Managing the future The ultimate stakeholders in this debate are yet to be born. One thing is certain: coming generations will not take water for granted. Because the future of water is dynamically bound to the present, now is the time for far-sighted leaders to act. Sustainable planning is no longer an isolated challenge; regional solutions require integrated planning among municipal, industrial and agricultural water users. Proactive watershed management is key to helping a community optimize its water opportunities. A holistic water review should examine the best combination of solutions for a community – conservation, non-potable reuse, indirect potable reuse, impaired waters from brackish or contaminated waters, desalination or water sharing among adjacent communities. These are not easy decisions – but they must be addressed.

The year 2007 left many water watchers breathless. There was activity all over the state. New
In rural West Bengal, India, life is tenuous for millions of people. Desperate poverty, hunger, and disease are a daily reality. To make matters worse, their water is killing them. With every drink of water and every meal they eat, hundreds of thousands of people are being slowly poisoned by the very water they need to survive.
Water For People began working in India in 1996. Its initial effort was a small pilot program designed to help eliminate the health threats of arsenic in rural village water supplies. Soon Water For People partnered with Bengal Engineering & Science University to develop a local, sustainable solution.
The future of water is anything but clear. We face a future world fraught with water challenges – too much, too little, too contaminated or inaccessible to meet our needs.
