  1. Sanitary District Generates EPA Award By Turning Trash To Treasure
    4/3/2018

    The Greater Lawrence Sanitary District (GLSD) in North Andover, MA, was one of 28 organizations nationwide to be honored for an innovative water or wastewater project in the most recent PISCES Recognition Program sponsored by the Clean Water State Revolving Fund (CWSRF). PISCES stands for Performance and Innovation in the SRF Creating Environmental Success.

  2. 4-Step Wastewater Sludge Treatment Process
    4/3/2018

    Sewage sludge is a byproduct of treated wastewater. It is composed of both organic and inorganic materials, a large concentration of plant nutrients, organic chemicals, as well as pathogens. Therefore, it is extremely important to properly treat such sludge in order to minimize its environmental repercussions.

  3. How To Save Costs With Simple, Effective Data Management

    Water and wastewater utilities must monitor numerous aspects of their systems on a continuous basis. Various instruments are used to measure these processes, producing volumes of data every day. Endress+Hauser is a leading supplier of products and services for process measurement and automation. Water Online spoke with three of Endress+Hauser's experts to find out how data loggers and managers can save costs while providing effective data management. 

  4. Farm Community Effort Leads To Improved Drinking Water For Thousands
    3/28/2018

    All communities depend on clean water and that supply of clean water depends on the actions of members in the community and outside of it. The small city of Kutztown lies within the Saucony Creek watershed in Berks County, Pennsylvania. The watershed is mostly agricultural, dotted with small family crop and livestock farms, and the activities on these farms affect water supplies near and far.

    A deep dive into reverse osmosis (RO) elements reveals the importance of feed channel spacers for optimal membrane filtration system performance.

  7. 3 Public Works Professionals Tap Technology To Address Infrastructure Challenges
    3/13/2018

    The digital revolution has reached our utilities, but not everyone is taking advantage of how it can, for example, make water and wastewater cleaner, healthier, and more efficient. National news media seemingly report daily on U.S. infrastructure, but they rarely get down in the trenches with the public works professionals who are accomplishing so much. Three of them, who are using the Internet of Things (IoT) to better manage critical assets, tell their stories here.

  8. Selecting The Best Solution For PFAS Removal
    3/5/2018

    Protecting the public health and ensuring water is safe to drink is the highest goal of water system managers. Negative health effects are indicated from exposure to per- and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctyl sulfonate (PFOS). Based on lab studies, the U.S. EPA has issued a health advisory for PFOA and PFOS in drinking water of 70 parts per trillion. While health advisories are not enforceable, they offer a margin of safety for consumers.

  9. Water And Wastewater Pipeline Infrastructure Opportunities
    3/2/2018

    There is little doubt that America’s infrastructure is aging, and in some cases, operating well beyond its originally intended lifespan. With labor costs representing up to half of the cost of pipe replacement, the key to cost-effective water and wastewater utility strategies revolves as much around labor-saving installation efficiency as it does around the physical performance of a particular material. Here is a look at historic failure rates, causes, and factors to consider when replacing existing water distribution and sewer networks.

  10. Leveraging Federal Funds To Aid Local Sewer Improvements
    2/27/2018

    Inflow and infiltration (I&I) are ongoing concerns for many wastewater utilities. Even with diligent maintenance of infrastructure, there are limits to what can be controlled. One example of that is leakage in the lateral service lines connecting the sewer utility’s main to sewer customer buildings. Here is how one municipality took advantage of federal and local funding to encourage nearly 2,500 customers to upgrade deficient connections in their lateral service lines — to the tune of more than $4 million.
