Water 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.
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.
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
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
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
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.
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.
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.
