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.
When community and infrastructure collide
Many water infrastructure projects require
public outreach. Typically, stakeholder groups are brought into the development
process and educated about water infrastructure requirements and challenges.
From this process, their input helps to guide design and construction. Once the
project is completed, the interaction typically ends. However, a recent project
for the City of West Sacramento, Calif., embraced these valuable community
water infrastructure elements as an educational outreach opportunity to inform
customers and provide an asset, instead of a liability, to the surrounding
Floating a fix
When it rains, roadway runoff has to go
somewhere. In many cases, it is conveyed to a nearby receiving waterbody
through such secondary drainage systems as culverts, ditches, and canals. Along
one stretch of road in the northeast part of Orange County, Fla., the Bates
Road Canal carries runoff from surrounding neighborhoods, businesses, upstream
areas, and Bates Road itself. Because of severe erosion, the canal was in
danger of becoming a safety hazard.
Water rights … even after it leaves the pipe?
Antonio Water System petitions to retain ownership of treated effluent after it
enters the San Antonio River
In the drought-ridden Southwest, water has become
increasingly coveted. Those who have it want to protect it. The San Antonio
Water System (SAWS; San Antonio) is doing just that. SAWS filed an application
with the Texas Commission on Environmental Quality (TCEQ) for a “bed and banks”
authorization to transport high-quality treated effluent to the San Antonio
Bay, according to a SAWS news release. Essentially, the application secures
SAWS ownership of the wastewater it treats even after it leaves the water
resource recovery facility.

Details make the difference
the small stuff may cause some headaches, but it also produces reliable
results. With ever shrinking permit limits and tighter budgets to meet for
energy and chemical use, excess is the enemy. Not only does paying attention to
details yield better outcomes, it can even earn you a trophy.
energy always is listed as one of the top expenses for water resource recovery
facilities. Great pains are taken to ensure proper motor configuration, the
correct diffuser selection, and efficient operations using varying levels of
process control. One other area that deserves attention is piping the air to
the diffusers. Misaligned pipe joints can lead to air leaks and increased
energy costs during operation. One option to ensure more custom-fitted joints
are mechanical couplings. These couplings serve triple duty in that they join
the pipe, handle misalignment, and accommodate thermal expansion and
contraction without the need for specialty devices.
in the December issue, is a full report on Operations Challenge 2014. WEFTEC
2014 in New Orleans hosted the 27th annual competition. During the 2-day
competition, 43 teams battled through five events to see who would reign
supreme. After paying attention to the smallest details in safety, process
control, laboratory, collection systems, and maintenance events, Terminal
Velocity from the Virginia Water Environment Association earned an
unprecedented fifth consecutive win in Division 1. Team HRSD, also from
Virginia, earned the Division 2 title.
