How to Prepare for the Reduction of Lead in Drinking Water ActOriginally Broadcasted on July 11, 2012
Provisions to the Reduction of Lead in Drinking Water Act will take effect in 2014, reducing the permissible amount of lead in water distribution system products from as much as 8 percent to no more than 0.25 percent. In this webcast, attendees will learn about zero lead materials available today. Topics covered will include an overview of legislative and standards body requirements and which materials are suitable for commercial and industrial customers versus residential customers.
White Papers:The Skinny on LeadJanuary 4th, 2014, is fast approach-
ing and will bring sweeping change to
water utilities in how they comply with
the Safe Drinking Water Act. Strict
new mandatory requirements and fi xed
deadlines face the nation’s nearly 60,000
utilities, yet the majority are not familiar
with the legislation and how it will
impact them. Learn more about NSF’s
Joint Committee standards for lead in
drinking water and national require-
ments, the development of these new
standards and what these changes mean
for you.
Measuring Methane-Based Digester Gas Flow Wastewater Treatment PlantsProcess and plant engineers at municipal
wastewater treatment facilities need to
measure, monitor and dispose of meth-

in their operations. This white paper
will discuss systems that offer accurate
and repeatable gas fl ow measurement in
all phases of operation. Flow rates can
vary from low production in start-up
phases to much higher fl ows as the
process matures and with seasonal and
population changes.

Groups Seek Guidelines to Protect Groundwater from FrackingBy Patrick Crow, Washington Correspondent -----------------------------------------------------------------------------------------------------------------------------------------------
Three water groups have proposed
guidelines to protect groundwater
from the hydraulic fracturing of oil
and gas wells.
The American Water Works Associa-
tion, the Association of Metropolitan
Water Agencies and the National Asso-
ciation of Water Companies said oil and
gas developments must protect ground
water and surface water resources.
They said the Environmental
Protection Agency (EPA) should
use existing Safe Drinking Water Act
(SDWA) authority to regulate oil and
gas well construction and operation
through the Underground Injection
Control (UIC) program.
Also, Congress should remove
statutory barriers impeding federal
regulation and oversight of oil and
gas wells under the UIC program,
particularly involving fracturing.
They said EPA should also use its
Clean Water Act (CWA) authority to
regulate discharges to surface water
bodies from oil and gas operations,
including the expedited preparation of
effl uent guidelines under the CWA’s
National Pollution Discharge Elimina-
tion System program.
Finally, Congress should provide
adequate resources to EPA and
partner federal agencies necessary to
support timely research and regulatory
oversight under the SDWA, CWA and
other appropriate statutes.
The water groups said that the
impact of drilling and completion
activities on ground water and surface
water supplies should be actively
monitored, and the federal govern-
ment should ensure the that hydraulic
fracturing activities are reported to
local governments.
“Notifi cation is critical to addressing
community impacts, including mitigat-
ing potential implications for drinking
water supplies. Drinking water systems
need information about the chemicals
to be injected in conjunction with
hydraulic fracturing activities, as well as
the amount and sources of water to be
used,” they said.
Pennsylvania Water Study
The U.S. Geological Survey and
the Pennsylvania Department of
Environmental Protection detected
low concentrations of contaminants --
including pharmaceuticals, hormones
and organic wastewater compounds
-- in rivers and streams throughout
Pennsylvania during a four year study.
“These fi ndings are intended to help
wastewater and drinking water manag-
ers to make decisions about water treat-
ment options given the ever increasing
number of new compounds that come
into use and end up in the state’s water-
ways each year,” said Andrew Reif, the
USGS scientist who led the study.
The 10 most frequently detected
compounds represented a wide variety
of uses, but all were derived from
human sources. None of the most
commonly detected compounds were
typically used in agricultural opera-
tions and most entered the stream en-
vironment from municipal wastewater
treatment facilities or septic systems.
Throughout the state, the most
commonly found compounds in
stream water were caffeine; acet-
aminophen; carbamazepine – a seizure
medication; sulfamethoxazole and
trimethoprim – antibiotics; and the
hormone estrone. Other commonly
detected compounds include the
antihistamine diphenhydramine; the
antibiotics azithromycin, erythromy-
cin, and ofl oxacin; the fl ame retardant
tri(dichloroisopropyl) phosphate; and
the insecticide DEET.
In the heavily agricultural south-
central part of the state, the most
commonly detected contaminants
in stream water samples were car-
bamazepine, sulfamethoxazole, and
tri(dichloroisopropyl) phosphate–a
fl ame retardant. The contaminants

• Most need careful alignment
• Usually cannot damp vibration
Elastomer Material Flexible
Couplings
Material-fl exible couplings employ-
ing elastomeric materials are numer-
ous. Elastomers generally do not have
a well-defi ned fatigue limit. However,
most elastomers do suffer some form
of degradation from heat and require
de-rating at elevated temperatures.
Heat develops in the material when
the coupling fl exes, and claims that
they will operate at severe misalign-
ments are often very misleading. Any-
thing other than moderate misalign-
ment will severely limit coupling life.
Elastomeric fl exible material couplings
advantages are as follows:
• Generally do not have defi ned
fatigue limits
• Torsionally soft / good vibration
damping
• No lubrication or maintenance
• Less expensive than metallic couplings
• Lower reactionary loads on bearings
• More misalignment allowed than
metallic types
Elastomeric fl exible material coupling
limitations:
• Sensitive to chemicals / high tem-
peratures
• Larger outside diameters than me-
tallic couplings
• Diffi cult to balance as an assembly
• Some types have low overload
torque capacity
Magnetic Couplings
The same basic coupling used for
the “Adjustable Speed Permanent
Magnet Drives” spelled out in last
month’s Pump Tips Column, can also
be used in a simplifi ed version as a
constant speed pump coupling, with
some distinct advantages. The biggest
advantage is that the air gap allows the
coupling to tolerate the highest shaft
misalignment of any coupling type, to
the point that laser alignment of the
pump and motor shaft is not neces-
sary. Also, it will not transmit vibra-
tion and/or forces between the pump
and motor. This can increase bearing
and mechanical seal life in pumps and
bearing life in motors.
Advantages of magnetic couplings:
• Low maintenance, does not require
periodic lubrication
• Tolerates gross parallel and angular
misalignment.
• Eliminates vibration transfer be-
tween motor and pump
• Increases seal life
• Permits shock loading
• Overload torque protection, self-
resetting
• Cushioned starts and stops
Limitations of magnetic couplings:
• High initial cost
• Couplings will experience a 1% - 3%
slip (slight speed reduction)
• Heat sensitive:
– Induction current adds heat to
driven portion of coupling
– Excessive heat can weaken perma-
nent magnet strength.

To protect area streams and rivers,
the City of Detroit began building a
network of combined sewer overfl ow
basins 25 years ago. Today, the de-
partment operates eight such basins,
strategically sited in places where
storm runoff would otherwise reach
area rivers. By capturing and sub-
stantially treating the stormwater, the
basins play a major role in protecting
the surrounding watersheds, and the
people and wildlife living there.
In just the fi rst three months of
2011, for example, the basins col-
lected more than 5 billion gallons
of runoff that would have otherwise
escaped into waterways. While a third
was pumped to the main plant for
treatment, the rest of that water was
treated in the basins.
Each combined sewer overfl ow facility
differs somewhat in size and design, but
all basically apply the same treatment
process: retaining the overfl ow, mechani-
cally screening out solids, and disinfect-
ing the water with sodium hypochlorite
(bleach). Basins also have equipment
that operators use to monitor fl ow rate
and volume, collect samples, remove
residual water from the basins, and clean
them after a wet-weather event.
Despite their similar functions, the
basins’ process control instruments
vary widely. That’s partly because
the basins were constructed over
the course of the last three decades
at a time when automated control
technology was quickly evolving. The
comparatively slow pace of public
works projects was also an issue. From
concept to commissioning, each basin
required several years to complete be-
cause of strict municipal codes requir-
ing public planning, open bidding and
offi cial oversight. Meanwhile, federal
and state water quality standards were
becoming more stringent, adding
another layer of complexity.
“Through the years, we’ve had to
update the process control systems at
various basins to comply with chang-
ing regulations,” said Anil Gosine,
Process Control System Administrator
for the Detroit Water and Sewerage
Department (DWSD). The result is a
“myriad of different process control
systems at different locations. At one
basin, we have process control equip-
ment from four different vendors.”
Such a hodge-podge of legacy
equipment makes integration diffi cult
or impossible.
“The lack of a standardized plat-
form also hampers troubleshooting
and maintenance,” Gosine said. “In-
ventory is another problem, because
we need to keep so many different
spare parts on hand.”
In 2004, DWSD hired a consultant
to design new, more effective and ef-
fi cient control systems for two existing
Combined Sewer Overfl ow Facilities.
DWSD engineers specifi ed Rockwell
Automation as the vendor for the
process control systems after per-
forming a life cycle cost analysis.
The new system leverages the
company’s PlantPAx™ Process
Automation System, which is an
integrated control and information
system. System integrator Process
Control & Instrumentation (PCI),
LLC, was awarded the contract for
replacement of non-functional control
system instrumentation at two DWSD
CSO Basins. PCI, a control engineer-
ing fi rm with an offi ce in Detroit,
worked with DWSD on other recent
projects, giving PCI engineers a good
understanding of the DWSD overall
SCADA system.
But PCI faced a dilemma when it re-
ceived the contract to retool the basins.
The company had strategically offered
the lowest bid to win the project with
DWSD, as well as partner with Rockwell
Automation for the fi rst time. However,
PCI engineers were concerned that the
total cost of replacing the obsolete con-
trol systems would exceed the agreed-
upon contract amount.
Rockwell engineers recommended
a solution that kept the project within
budget – its PlantPAx Process Library
and Water/Wastewater Accelera-
tor toolkit. The process library is a
software application for the Logix
Control Platform that includes an
array of pre-engineered code that can
be used in various applications. It also
incorporates custom faceplates based
on specifi c plant roles, information-
laden icons and full documentation.
The Water/Wastewater Accelerator
toolkit customizes those elements to
signifi cantly reduce the time required
to design, install, operate and main-
tain a wastewater project. The toolkit
contains confi gured fi les, selection
tools and examples of how to connect
the Allen-Bradley® ControlLogix®
controller to the facility’s human
machine interface (HMI) hardware
and other devices over EtherNet/IP™
and DeviceNet™ networks. The tool-
kit also provides system architecture
drawings, basic status, control and di-
agnostic logic, as well as faceplates for
FactoryTalk® View Site Edition HMI
software from Rockwell Automation
used in the new Detroit basins.
“In the past, we’d have to program
the HMI separately from the con-
troller and then link them together.
The toolkit comes with 80 percent of
the necessary code, predefi ned and
factory-tested. So you’re free to focus
on customizing the machine control
for the customer,” said PCI’s controls
CSO Facility Replaces Obsolete Control SystemsThe new system provides integrated data from the two CSO basins, helping improve diagnostics and allowing for more preventive and predictable maintenance.

New Orleans to Host WEFTEC 2012WEFTEC 2012, the annual event hosted by the Water Environment Federation, will take place Sept. 30 through Oct. 3 in New Orleans, LA. The program in-
cludes 130 technical sessions, 24 workshops and eight local facility tours, and is expected to draw thousands of water quality professionals and exhibitors from
around the world. To date, nearly 900 companies have already reserved over 290,000 net square feet of fl oor space at the New Orleans Convention Center.
For more information on the event, and details on the individual paper presentations, visit www.weftec.org.
Nutrient removal and recovery
will be among the important topics
discussed at this year’s WEFTEC con-
ference, set for Sept. 30 through Oct.
3 in New Orleans. Across the coun-
try, and especially in key watersheds,
utilities are being challenged to meet
increasingly stringent nutrient limits
for wastewater discharges. At the same
time, there is a growing interest in
recovering nutrients from wastewater,
especially phosphorus.
Ana Pena- Tijerina from the City of
Fort Worth, TX, and Rajendra Bhatta-
rai from the city of Austin, will discuss
the challenges they’ve faced in trying
to help develop nutrient criteria for
the state of Texas. Their paper, “The
Texas Two-Step: Developing the Nu-
meric Nutrient Criteria for the Second
Largest State in the U.S,” will discuss
the challenges, and frustration, they
have experienced as they’ve worked
through this process.
Bhattarai said “a dance” has been
going on between USEPA and the
Texas Commission on Environmental
Quality (TCEQ),
with EPA insist-
ing on strict
numeric criteria
for total nitrogen
and total phos-
phorus, while
Texas has put
forward surro-
gate criteria as an alternative. In 2010,
TECQ submitted criteria for 75 major
reservoirs in the state but they have
yet to be approved by EPA.
“We realize that what we are seeing
here in Texas is not really any different
from what other states are seeing or fac-
ing. The challenges are the same,” said
Pena- Tijerina. “The reason for this pa-
per was to make the point that we have a
common problem here. The challenges
are basically the same, and maybe we can
work together to solve these issues.”
One major challenge has been the
low numeric levels sought by EPA,
which would be diffi cult and expen-
sive to achieve with current technolo-
gies, Pena- Tijerina said.
“Most of the wastewater treat-
ment plants here in Texas are smaller
than 10 mgd, so having to install the
technologies needed to achieve those
very low numeric criteria is just not
possible,” she said.
Stephanie Sansom, a supervising
engineer at MWH, will present a
paper that highlights the challenges
faced by utilities trying to meet low
numeric criteria. Her paper, “TN and
TP - How Low is Low and How Do
We Get There?” highlights a series of
treatment plant projects designed to
tackle low nutrient levels.
In one example pilot project in
Florida, the treatment facility faced
two different phosphorus limits --
0.27 mg/l for reuse in wetlands appli-
cations and a very tough 0.005 mg/l
for discharge to Class 3 Outstanding
Florida Waters.
The pilot project used MBR, chem-
ical addition for additional phospho-
rus precipitation, followed by reverse
osmosis and then advanced oxidation
processes, Sansom said.
“The point of that plant wasn’t to
look at the various technologies, it
was really seeing if we could actu-
ally get to that (0.005 mg/l) level by
throwing everything at it,” Sansom
said. “We could achieve the .27 level,
but we could not achieve the .005.
We came close. We
got down to point
.007 on one or two
samples.”
The facilities in
her study were all
discharging to sensi-
tive water bodies
and had limits that
went beyond those imposed by US
EPA, she said.
“We found that MBR systems
can remove dissolved phosphorus
after chemical addition. Ultra fi ltra-
tion have been successful at rejecting
particulate sections of phosphorus
and that can be enhanced by chemical
addition, and then reverse osmosis has
various rejections,” Sansom said.
Still, few treatment facilities would
be willing or necessarily able to install
an RO system to achieve extremely
low nutrient levels, she said.
“For every additional point or ad-
ditional .5 of phosphorus or nitrogen,
you have to consider how much ad-
ditional energy does it cost, how much
additional chemicals,” Sansom said.
“Obviously, there is a limit not only on
technology but what treatment plants
are willing to spend on capital and op-
erational expenditures. And you have to
ask, at what point does the technology
or operational requirements outweigh
the sustainability of the plant?”
Nutrient Recovery
While utilities are struggling to
meet – or prepare for – tighter nutri-
ent limits, there is a growing interest
in resource recovery in the wastewa-
ter treatment industry. Recovering
nutrients for reuse can help preserve
resources and also potentially help
offset the cost of treatment, said Dr.
James Barnard of Black & Veatch.
Barnard will present a paper en-
titled “State-of-the-art Recovery Of
Phosphorus From Wastewater.” The
paper will examine both biological and
chemical recovery system and look at
work underway in the US and abroad.
Barnard is recognized for his devel-
opment of biological nutrient removal
processes. He said phosphorus is a
limited resource and will grow in value
in the years ahead. While chemical pre-
cipitation can produce a viable fertilizer
product, he prefers biological processes
for recovering phosphorus. He said the
two processes can be used in combina-
tion to help increase recovery as utilities
strive to meet lower discharge limits.
As more facilities turn to biological
phosphorus removal, a large fraction
of the nutrient becomes concentrated

Stormwater runoff has been called
the single most common cause of
pollution in our nation’s waterways,
carrying a variety of pollutants, such as
sediment, bacteria, organic nutrients,
and hydrocarbons to our watersheds
and degrading water quality. But
controlling and managing a non-point
source of pollution isn’t easy — fl ows
can be unpredictable, pollutants are
variable, and regulatory requirements
can be confusing. Couple that with
very limited funding and you’ve got a
perfect storm indeed.
This year at WEFTEC, stormwa-
ter will be covered like never before.
“Compared to previous years, there’s
been an overall increase in the topic
[of stormwater] and the program
refl ects that,” said WEF’s Stormwater
Program and Policy Manager Seth
Brown. Nearly 40 papers across seven
sessions will delve specifi cally into
stormwater and green infrastructure
topics, exploring such themes as estab-
lishing stormwater utilities; sustain-
able stormwater infrastructure design;
managing urban stormwater with
trees; and using computer modeling
to help manage the impact of rain
events on watersheds.
This is the second year WEFTEC
has planned a dedicated stormwater
track, something Brown said is a refl ec-
tion of the maturation of WEFTEC’s
programming. “In the past, storm-
water topics focused primarily on wet
weather issues like CSOs,” he said.
“While that’s still part of what we do,
we are starting to diversify and talk
about things like rainwater harvest-
ing, sediment and erosion control, and
fi nancing options for stormwater.”
In addition to the traditional Tech-
nical Sessions, WEFTEC will offer
for the fi rst time this year a number
of Featured Sessions, which follow a
somewhat different format — includ-
Spotlighting Stormwater at WEFTEC.12 By Angela Godwin, Chief Editor
The lines between stormwater,
drinking water, and wastewater are
quickly fading as we begin to embrace
the concept of holistic water manage-
ment, the idea that all of our water
resources are not only interconnected
but interdependent. It’s worth noting
that a new session at WEFTEC this
year will bring water leaders from sev-
eral different sectors together to share
their perspectives on how to work
smarter — not harder — to manage
water and meet our quality and quan-
tity needs. On Monday, October 1,
10:30 AM - 12:00 PM, join WEF’s
Executive Director Jeff Eger and fi ve
distinguished speakers for insights
into their urban water management
visions and strategies for attaining
it. Speakers include: DC Water’s
George Hawkins; American Water’s
Jeff Sterba; Xylem’s Gretchen Mc-
Clain; University of South Florida’s
Kala Vairavamoorthy; and U.S. EPA
Administrator, the Honorable Lisa
Jackson (invited).

Elastomer Valves Provide Solutions in Backfl ow, Slurry ApplicationsBy Chris Raftis --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The most critical part of any valve is
its engineering and construction. Elas-
tomer valves are built to specifi cally
provide low maintenance and long life
span in the toughest applications. The
design of an elastomer valve provides
trouble-free, high wear-resistance that
outperforms and outlasts many other
valve styles.
Elastomer valves are ply reinforced,
much like an automotive tire. Special
plies of nylon, polyester and Kevlar
fabrics provide the structural support
within an elastomer valve and form
the pressure-containing vessel. The
wear surface of an elastomer pinch
valve is vulcanized to the ply and is
chosen on the basis of compatibility
with the process fl uid. Elastomer
valves can be built to suit almost any
process condition. Large-diameter and
high-pressure designs are available, as
are variations in elastomer thickness
for severe conditions.
Year after year, millions of dollars
are spent in the United States when
CSO systems allow receiving waters
to enter into sewage treatment plants
and collection systems. The unique
characteristics of elastomer valves
make them ideal for backfl ow preven-
tion in these applications.
Developed specifi cally for CSO
and diversion chamber applications,
elastomer valves such as the Tide-
fl ex® Check Valve and Tidefl ex®
CheckMate® Inline Check Valve can
A cutaway drawing of a elastomer pinch valve sleeve, showing the plies.
With a maximized bill height that increases the open area, headloss in elastomer check valves is signifi cantly reduced.

San Francisco Nears End of $4.6 Billion Improvement ProgramBy Harlan L. Kelly ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SFPUC customers are currently served by 280 miles of pipelines, 60 miles of tunnels, 11 reservoirs, fi ve pump stations and two treatment plants that bring snowmelt from the Sierra Nevada Mountains to the cities that surround the San Francisco Bay. Pipelines and tunnels from the Hetch Hetchy Reservoir cross three major earthquake faults with the potential to interrupt water service for days and weeks.
In June, the New Irvington Tunnel Project achieved a signifi cant milestone when two teams of miners met 420 feet underground to complete a major tunnel section.
The Bay Tunnel, the fi rst bored tunnel under San Francisco Bay, will be built using this 600-foot-long tunnel boring machine.

project is on schedule to be completed
in 2015. Once completed the fi nal
tunnel lining will consist of a 9-foot-
diameter welded steel pipeline.
The New Irvington Tunnel in the
Sunol region is the second of the
three tunnels being built as part of
the WSIP. This 18,660-foot-long
tunnel has a construction budget of
$238 million and is expected to reach
completion in the spring of 2015 us-
ing a conventional tunneling method.
This tunnel is horseshoe shaped with
excavated dimensions of approxi-
mately 12 feet by 14 feet. It is being
excavated through Briones Sandstone
and Tice Shale rock formations, and
through seven secondary fault zones
in four tunnel headings. Two headings
are driven from each end of the tunnel
at surface portals, and two headings
are driven from an intermediate 41
foot diameter by 115 feet deep shaft.
In June, after 13 months of digging,
miners from two of the headings met
up with each other underground.
This ‘hole-through’ allowed the road
header teams from the Irvington
Portal in Fremont and the Vargas
Shaft 4,500 feet away to shake hands
somewhere under the mountainside
and formally complete this section of
tunnel excavation.
The work on this project must be
conducted under a “gassy tunnel”
designation from the state’s health
and safety agency. Originally, the tun-
nel was designated “potentially gassy”
and then was assigned the “gassy”
designation late last year. This has
placed additional obligations on the
construction management team and
contractor for tunnel ventilation, gas
monitoring, and safety practices, but
they are performing at peak levels.
The new tunnel alignment runs paral-
lel and just south of the existing tun-
nel and will greatly assist with main-
tenance and redundancy priorities for
the agency. The fi nal tunnel lining
will be mortar lined, welded steel
pipe, resulting in an 8.5 feet fi nished
diameter.
Our fi nal WSIP project is the
rebuilding of the Calaveras Dam in
southern Alameda County, nearly 90
years old and once heralded as the
world’s largest earth dam. In 2001,
the water levels at the Dam were low-
ered to less than 40 percent of original
capacity because of seismic instability.
The storage is crucial to providing
adequate water in times of drought.
Once the new dam is rebuilt, the dam
will withstand a 7.2 magnitude earth-
quake. The new 210-foot-high earth
and rock fi ll dam will be constructed
immediately downstream of the exist-
ing dam and will have a crest length of
1,210 feet, a base thickness of 1,180
feet, and a crest thickness of 80 feet.
The total volume of the dam will be
approximately 3.5 million cubic yards.
Due to the location of the existing
Calaveras Dam in protected watershed
lands, the project faces many hurdles.
These include building the new dam
in such close proximity to an active
earthquake fault and in an area with
complex geological conditions, ensur-
ing environmental compliance in a
pristine environment with numerous
threatened and endangered species,
as well as the presence of naturally
occurring asbestos, which is found in
the Franciscan Complex mélange and
serpentinite rocks. All of these factors
have led to the implementation of
extraordinary precautions and mitiga-
tion measures to address conditions
and ensure project completion. The
$416 million project broke ground in
September 2011 and is currently 20 Circle No. 97 on Reader Service Card

Leak detection
Aclara’s STAR® ZoneScan leak-detec-
tion solution was jointly developed
by Aclara and Zurich-based Guter-
mann International. The system
employs data loggers placed
on main valves that sample
the sound waves generated
by leaks. The data is automati-
cally sent to the utility over the
Aclara STAR® Network. There,
the system’s software correlates the
data, pinpointing any leaks to within
a few feet. The system can save municipal
water utilities time by identifying possible
leak locations remotely. It also encour-
ages water conservation by helping utilities
identify and fi x leaks before they become

We’ve heard of the “water energy
nexus” but few recognize its impor-
tance. If the public were fully aware
of its signifi cance, we would see many
more “green” projects than we are
witnessing now. I think full compre-
hension would result in dramatic,
concern-driven actions to address this
critical connection of two incredibly
valuable resources.
On the subject of water supply,
we look at the amount of water in
the world and breathe easy, thinking
enough water is available. To what-
ever degree this may be true, the full
cost to obtain it is not at all obvious.
We have been oblivious to this cost
due largely to government subsidies
masking the true cost of water, and
the true costs to treat wastewater. If
we removed the subsidies and paid the
true costs, our opinions would change
drastically. Water-saving and energy-
saving movements would become
widespread and urgent.
On the wastewater side, the energy
potential contained in wastewater
and its biosolids/biogases exceeds by
10 times the energy used to treat it.
(Source: Water Environment Research
Foundation) Some WWTPs produce
100 percent or more of the energy
they need to operate, and WWTPs
collectively could potentially meet
10 percent of the national electricity
demand. (Source: Water Environment
Research Foundation) This represents
a tremendous opportunity for the
wastewater industry.
In life, we reach points where
something has to change, and this
nexus of (waste)water and energy is
such a point. Our collective ability to
understand the costs and act accord-
ingly will be vital to assuring clean
water supplies well into the future.
I’ve been in the municipal water
and wastewater market for nearly
30 years. It amazes me how little
attention energy use has received
over the thousands of projects I’ve
been involved in. We in this market
understand our involvement in envi-
ronmental protection, so the recent
green movement pleases our psyche.
The implementation of the term
“green” means a lot to our mother
earth and to our children’s children.
Our responsibility is to carry the fl ame
and design away the unnecessary costs
in wastewater treatment with innova-
tive designs, which start mainly with
awareness of energy costs.
I’ve had an opportunity to ask
operators, “How much is your power
bill?” Often times I get blank stares
or replies such as, “That’s the city’s
problem”. The operator’s main re-
sponsibility is safe and effective opera-
tions of their plant and to ensure clean
drinking water or properly processed
wastewater. Energy costs are under-
standably not a priority for them.
But they need to be a priority for the
municipalities and the engineers that
design the plants.
We as environmentalists need to
determine a way we can unite both the
plant function and its energy manage-
ment. I feel that through awareness, ed-
ucation and incremental measures, water
resource management can be improved
and energy use reduced signifi cantly.
Few of us know that thermoelectric
power plants use 41% of our avail-
able fresh water to produce electricity.
(Source: National Energy Technology
Laboratory) Thermoelectric generation
is expected to increase 18% from 2005-
2030, putting even more strain on
water supplies. (Source: Water Manage-
ment in 2010 and Beyond) It’s also not
well known that a thermoelectric power
plant consumes 300—400+ gallons per
megawatt of power generated (Source:
U.S. Department of Energy, 2006 Re-
port to Congress of the Independency
of Energy and Water, Washington
D.C.) and that power plant construc-
tion in some areas is being held up due
to water scarcity. (Source: Energy Law
Journal , Vol. 30:11)
A wastewater plant’s largest energy
consumption is in aeration, by as much
as 60%. (Source: Consortium for
Energy Effi ciency, 2007) This being
the case, it is obvious that plants’ col-
lective energy costs across the country
will continue to rise with the increase
in treated volumes. Thus, the crisis of
the water energy nexus: that growing
power production places greater strains
on water supplies and more wastewater
treatment consumes more energy.
WWTP effl uent has been success-
fully used as cooling water for power
plants. It’s also known that 81% of
power plants proposed for construc-
tion have one or two WWTPs within
a 10-mile radius, and those plants
could provide a suffi cient cooling
water supply. Further, 97% could
meet their cooling needs with one to
two WWTPs within 25 mile radius.
(Source: U.S. DOE Study, Reuse of
Treated Internal or External Wastewa-
ters in the Cooling Systems of Coal-
Based Thermoelectric Power Plants)
With awareness and knowledge of
the facts, municipalities can look to
site WWTPs near existing or proposed
power plants, with the potential to
sell the clean effl uent to the plants
for cooling water. Biosolids and/or
biogases can be recovered and sold
to those same plants as fuel. Or they
could be used on site to generate pow-
er to run the WWTP. New separation
technologies are capable of extracting
phosphates from the waste stream,
which can be sold to manufacturers.
It’s also possible that power plants
could own and operate adjacently sited
WWTPs, gaining direct access to water
& fuel outputs while also relieving cit-
ies of the capital expense of building a
plant. The options are numerous.
There are also many options for
reducing energy usage within a plant.
Whether it be simple awareness,
replacing older equipment with more
energy effi cient units, or modifying
on-off cycling of equipment, sav-
ings can be signifi cant. Benefi ts from
investing in energy savings can come
from Federal and State assistance pro-
grams or simply the savings on a treat-
ment plant’s power bill, all without
impacting the treatment quality.
Energy and water are tightly con-
nected, and WWTPs are at the heart
of that nexus. Awareness of that
relationship is the starting point. We
must innovate by moving toward
zero discharge facilities, where zero
discharge for this purpose means
completely recycling/reusing a plant’s
outputs. We must educate plant
personnel on energy usage; improve
process operations; and lower a plant’s
carbon footprint.
Through all of this, our country’s
WWTPs can do much more than just
save energy, they can actually become
cash cows from the tremendous ener-
gy potential contained in wastewater.
It’s imperative that we move forward
on this process. WW
