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.
Going with the flow
In a city as large as San Diego, with high demand for wastewater services and quickly-aging infrastructure, taking preventive measures to ensure its large pipes and facilities remain operational is critical. After inspectors set out to identify focus points for rehabilitation across San Diego’s 4989 km (3100 mi) of sewer lines, outside-the-box thinking and extensive coordination with community residents and businesses allowed repairs to move forward without ever needing to take the wastewater treatment system out of service.
In August 2013, an aging sanitary sewer pipeline collapsed below a busy roadway in Revere, Mass., necessitating emergency repairs. Following the collapse, the City of Revere rapidly developed and implemented a plan for rehabilitating and restoring service to the century-old sewer. Because of the complicating presence of multiple water mains just above the damaged pipeline, the city essentially had to conduct a major water project literally on top of the emergency sewer repairs.

Last year, the City of Los
Angeles Sanitation Bureau Hyperion Water Reclamation Plant (Playa del Rey,
Calif.) temporarily discharged wastewater effluent much closer to shore than
normal into the Pacific Ocean for 6 weeks while an outfall pipe was repaired.
Normally, the facility discharges effluent 8 km (5 mi) offshore into Santa
Monica Bay at a depth of 57 m (187 ft), where effluent can disperse in deeper
Moving the discharge to a depth of only 15 m (49 ft) elevated
the bureau’s public health concerns. Scientists from the bureau’s Environmental
Monitoring Division contacted several institutions involved in the Southern
California Coastal Ocean Observing System (SCCOOS; La Jolla, Calif.) for help
in monitoring ocean conditions during the 6-week period.

bag of tricks
Faced with finite resources and seemingly infinite
challenges, water sector professionals need every advantage they can gather.
This is especially true when it comes to maintaining infrastructure. Leaping
over the huge funding canyon between what needs to be done and what should be
done requires special tools — a vaulting pole would be good; a jetpack even
But even with a jetpack, the pilot needs to know what
to take and what to leave behind. In the case of water infrastructure, this
means separating the things that should be done from the things that must be
done. Luckily, the water sector continually develops tools and ideas that make
this possible. The September issue will present several examples of how the
water sector is developing these tools.
Ongoing advances in gathering, managing, and analyzing
data — often dubbed smart water and big data — are providing new tools.
Implementing every aspect of smart water and big data may not be practical for
all, but every utility can benefit from taking small steps toward becoming a
digital utility, driven by data.
pilot-testing and demonstration programs at utilities reveal complexities and
identify unknowns of emerging technology. This sort of targeted research and
development can help point out which new processes hold promise and which need
more work. Knowing how to get the most from pilot-testing, becomes a new skill
necessary to be a water sector innovator.
