WE&T Magazine

WET_cover1_August13_90Water Environment & Technology (WE&T) is the premier magazine for the water quality field. WE&T provides information on what professionals demand: cutting-edge technologies, innovative solutions, operations and maintenance, regulatory and legislative impacts, and professional development.

 


August 2013, Vol. 25, No.8

In many ways, the 87th annual Water Environment Federation Technical Exhibition and Conference (WEFTEC®) will be much like the previous 86 — packed with reliable and useful information on water and wastewater operations and engineering as well as a vibrant exhibition showing off the latest technologies and solutions. But much has changed this year as well. 

This year’s conference offers several enhancements that open the experience to new audiences, take full advantage of technology, and capture and share the expertise and opinions of everyone present. WEFTEC 2013 is not about attending, listening, or seeing; it’s about participating, interacting, and sharing.

Water, wastewater, and stormwater agencies respond to extreme weather events

extreme weather art The Water Environment Research Foundation (WERF; Alexandria, Va.), and the Water Research Foundation (Denver), joined forces with the U.S. National Oceanic and Atmospheric Administration (NOAA) and the U.S. Environmental Protection Agency to document the experiences of water service agencies dealing with extreme weather events in six areas across the U.S.  

 

From manual to automatic at Spring Creek

Spring Creek art When the time came for the Springfield (Ill.) Metro Sanitary District to replace the water resource recovery facility (WRRF) located on Spring Creek, staff members faced a leap into the future. The original Spring Creek facility had served the community for 84 years. To achieve a similar return on investment from a new facility would require the most advanced equipment, processes, and technology.

Meeting requirements, moving beyond

The water sector is driven by regulations primarily to protect public health and the environment. A new law or rule would require stricter discharge permits and would start a chain reaction of research, manufacturing, engineering, and operations to meet the new goals. This happens in the case of both liquid effluent and air emissions from water resource recovery facilities. 

The City of Greensboro, N.C., encountered precisely this situation when it set out to build a new fluid-bed incinerator to double its solids disposal ability. New strict maximum acheivable control technology air emission limits led to testing, tweaking, and plans to install new equipment. 

However, in some cases utilities are able to go far beyond permit limits to generate credits to be banked for future use or sold. For example, the Luling Oxidation Pond Wetland Assimilation System in Louisiana was the site of the first pilot project in the U.S. to determine the true costs, benefits, and barriers to implementation of using a wetland to generate carbon offset credits. This also is the first offset project in the U.S. that demonstrates the ability to create public–private partnerships that leverage carbon finance.
