Mathematical calculations can be one of the most challenging, but also most important, tasks performed by a water or wastewater operator. With Internet-enabled computers available in an increasing number of facilities, operators can lean on calculation tools to double-check their math. A recent SmallWaterSupply.org blog post features a list of math tools for small systems that was put together by the Missouri Rural Water Association. In addition to some interactive tools, it also features applications for your Smartphone. Check it out here!
A recent news release announces that Engineers at Oregon State University have made a breakthrough in the performance of microbial fuel cells that can produce electricity directly from wastewater, opening the door to a future in which waste treatment plants not only will power themselves, but will sell excess electricity. Researchers say this could eventually change the way that wastewater is treated all over the world, replacing the widely used “activated sludge” process that has been in use for almost a century. The new approach would produce significant amounts of electricity while effectively cleaning the wastewater. This could have an impact around the world, save a great deal of money, provide better water treatment and promote energy sustainability. The findings have just been published in Energy and Environmental Science, a professional journal.
Do you find this as exciting as we do? We would love to hear your comments!
From the Associated Press: TEA, S.D. – Water started flowing through the Lewis & Clark Regional Water System on Monday after more than two decades of planning and construction.
A treatment plant near Vermillion began producing water for distribution to 11 of the 20 member cities and rural water systems, including Sioux Falls.
The regional water system was incorporated in January 1990 with the goal of supplying 300,000 people in South Dakota, Minnesota and Iowa with water from the Missouri River.
“With our members unfortunately experiencing critical water needs in the face of a crushing drought, we are extremely pleased that Lewis & Clark is able to begin producing water just in the nick of time,” said Board Chairman Red Arndt, of Luverne. “This project has been an enormous undertaking. Words cannot express the range of emotions of finally reaching this point.”
The $462 million project is not expected to be finished for several years, and federal funding for construction is uncertain due to budget cuts.
“We continue to work tirelessly to ensure the remaining nine members are connected as soon as possible,” Arndt said.
A ribbon-cutting ceremony for the treatment plant is scheduled for Aug. 21 — the nine-year anniversary of the Lewis & Clark Water System groundbreaking.
