  1. Department of Agriculture Funds Wastewater Infrastructure For Rural Communities

    Federal funding of rural wastewater infrastructure projects is often assumed to predominantly flow through the Environmental Protection Agency (U. S. EPA)’s Clean Water State Revolving Fund created in 1987 under the Clean Water Act. However, in an interesting development, Anne Hazlett, Assistant to the Secretary for Rural Development at the U.S. Department of Agriculture (USDA), recently announced that the USDA would make a historic commitment to upgrade and rebuild rural wastewater infrastructure.

  2. Combining Wastewater-To-Energy Processes Could Power Large Cities

    According to Louisiana State University (LSU) Civil and Environmental Engineering Assistant Professor Xiuping Zhu, there is enough energy in U.S. wastewater to power 13 percent of U.S. households. And by harnessing the energy from wastewater alongside seawater and river water, Zhu believes that large cities could effectively be powered by extracting energy from these water sources.

  3. Wastewater Operations Consolidate Lab Tech Services

    As smaller public utilities strain against a lack of resources, many are pairing up to share the load. Two such cities are Libertyville and Mundelein in the Chicago, IL suburbs. Although deciding against consolidating their neighboring wastewater treatment plants, they recently agreed to share the cost and deployment of a laboratory technician. 

  4. Residents Embrace Wastewater Recycling As Means To Sustain Communities

    The Baldy View Chapter of the Building Industry Association of Southern California recently released a survey that showed strong support for using recycled wastewater to recharge groundwater basins.

  5. A Fresh Approach To Odor Control

    The disposal of biosolids is an age-old conundrum for wastewater treatment facilities, faced with a pungent mix of economic and societal demands. In an effort to understand the alternatives, Spokane, WA recently commissioned HDR Engineering to complete a $125,000 study, according to Spokane Public Radio.

  6. Sizing Up New York’s Wastewater Treatment Facilities

    A new report published in the February 24th issue of the Water Research journal evaluates New York State’s publicly-owned treatment works (POTWs) and asks the question, “Is Bigger Better?”

  7. Turbo Blowers Evolving For Large Sewage Plant Efficiency

    Until recently, multi-stage centrifugal blowers and gear-driven single-stage turbo blowers have dominated larger wastewater treatment plant (WWTP) operations. Turbo blowers in the 50 hp to 300 hp range have historically been popular for their low total lifecycle cost in mid-range WWTP applications (from 1 MGD to 20 MGD).

  8. Big Air: Aerzen Introduces Turbo Blower For Large Treatment Plants

    Aerzen USA has long preached — and excelled in delivering — "right-sized" blower solutions, offering energy efficiency by producing the proper amount of air for the application. Until recently, however, the company did not have an option for the largest of wastewater treatment plants. That has changed with the introduction of the Multicore series turbo blower, which is described in the following video by Tom McCurdy, National Sales Manager for Aerzen's Environmental Group.

  9. The Hidden Costs Of Aeration

    To ensure that aeration equipment will provide not only the best overall solution for their treatment needs but also the lowest total cost of ownership, design engineers and plant operators must take into consideration three primary factors: blower selection, right-sizing, and smart control systems.


  10. Stepping Up To Smart Aeration

    According to the U.S. EPA, municipal water and wastewater treatment systems account for 30 to 40 percent of the total energy used by municipalities in the United States. In wastewater treatment, the biggest chunk of this energy consumption comes from aeration. Within a typical WWTP, the aeration equipment used to maintain the required dissolved oxygen (DO) levels in the activated sludge process can account for as much as 60 percent of the total plant energy use (Source: As municipalities and plant operators look for ways to minimize energy use and contain operating costs, aeration is a natural area of focus.
