If there is one market that keeps coming up in conversation after
conversation with automation suppliers I meet at ARC, it is
water/wastewater.
There is the industrial side, getting water in and out of a plant for
manufacturing purposes, and the municipal side, delivering fresh water
to residents, and treating waste.
According to Tom Schaefer, Global Industry Solutions for
Water/Wastewater, Rockwell, the municipal side is truly a continuous
process, where “you never know what you are going to get, and you can’t
stop treating, no matter what.”
Condition of water is constantly monitored, and chlorine needs to be
added in just the right amounts to do the job, and not leave too strong a
taste. Each system has multiple redundancies to insure safe supply.
Wastewater treatment is “pump intensive,” often employing big motors
using lots of energy, so any automation supplier with a focus on energy
monitoring and savings (most we met today) is exploring growing this
market segment.
Mountainous or hilly communities where gravity can do much of the job
have an advantage, but flat areas (like Orlando where we are attending
the ARC) may have multiple remote pumping locations to keep pressure
up—not so much for your showering comfort, but to insure enough gravity
fed water for fighting fires in case of power outage.
In past years, crews with pick-up trucks would drive from location to
location visually checking on conditions of pumps, remote sensing and
reporting are now at work here.
Security is also a growing issue in protecting the nation’s water supply
and automation is playing a part here as well. One source told me some
computer hacking from foreign countries has taken place where pumps
have been turned on and off at a treatment facility, for instance.
One interesting note about municipalities, they differ from commercial
enterprises where successful implementation of automation is a closely
held secret. Municipalities are eager to share success stories with
colleagues in other local towns or states across the country.
