  • Vacuum Sewers – Engineered Solution for a Multitude of Problems

    ABSTRACTThe City of Albuquerque is celebrating its 300th anniversary in the 2006. The city itself has been growing at a very rapid rate, expanding the urban boundaries into the rural countryside. This urban expansion has been most apparent in the river valleys of the Rio Grande, where groundwater is shallow and topography is very flat. As the urbanization of the valley areas north and south of ...

  • An economical, environmental, and social comparison between vacuum and gravity sewers in decentralized sanitation systems, with Egypt as a case study

    The conventional gravity sewer is the most commonly used rural sewerage system in developing countries. However, this system has many technical, economic, environmental, and social disadvantages. Vacuum sewers could serve as a good competitor as an alternative system to conventional gravity sewers. A sample of 33 rural villages with populations of <10,000 people is selected from Egypt. A ...

  • Make your supplier part of your emergency response team

    Your supplier should then make a determination of what fits best. After there is some understanding of the problem at hand, the choice of a pumping system can be made. Your vendor will determine the best combination of a technical and practical solution. The technical factors are usually the easiest for someone to get a handle on. The challenges of the practical solution are more difficult ...

  • Who Says Charity has to Cost Money?

    It is a rare and delightful occurrence when altruistic motives and the quest for profit coincide in such a way that following one begets the other.  The reuse and recycling of waste water is just such a project, especially in industrial applications replacing municipal potable drinking water supplies.  When one considers the fact that more than a billion people in the world are without ...

  • Case study - City of Sault Ste. Marie - Pressure Monitoring

    The condition assessment project consisted of a Sahara pipeline inspection to detect any leaks or pockets of trapped gas on the lines, as well as a period of pressure transient monitoring on each pipeline to check for any sudden peaks or drops in the pressures which could be damaging to the lines. Service: Sahara Transient Pressure Monitoring Client: City of Sault Ste. Marie Type of ...

  • The The `Design for Autonomous Net-Zero Water Buildings` Project Funded By NSF

    The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water. The research team ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...
