Preface
Pipelines are the arteries of the modern world that convey the essence of what drives quality of
life, commerce, and public health for all of society. Whether conveying drinking water, collecting
wastewater, storage and conveyance of storm water, or transport of petroleum or other fluids –
pipelines are one of the most essential elements of modern infrastructure that impacts the way we
live and ability to improve the world around us.
This year’s conference theme is Revitalizing Global Underground Utility Infrastructure. It
focuses on the awareness that pipelines are a global topic essential to our quality of life; that we
have common issues and concerns independent of our nationality; and that our industry can work
together to truly develop solutions without borders. This is an exciting realization that holds hope
and promise for our future.
In coordination with the American Society of Civil Engineers, the technical program and this
publication were planned and implemented by the Technical Program Committee, led by the
Technical Co-Chairs. A call for abstracts was made for the first Pipelines conference outside of
the United States, from which well over 300 abstracts were submitted. These abstracts were then
sorted into tracks based on the general topic areas of Condition Assessment, Planning and Design,
Construction and Rehabilitation, Utility Engineering and Survey, Multi-discipline, and Technical
Posters. In addition, 5 panel sessions were included with topics from Women in Engineering to
Ethics to Emergency Response as well as other specialized technical topics. This resulted in an
extraordinarily high-quality program containing 175 papers and 15 poster presentations.
For publication purposes, technical papers from the eight presentation tracks were consolidated
into the following three subjects: 1- Pipelines 2018: Planning & Design, 2- Pipelines 2018:
Condition Assessment and Construction & Rehabilitation, and 3- Pipelines 2018: Multidiscipline
Topics and Utility Engineering and Survey.
On behalf of the Technical Program Committee, we are pleased to offer you the Proceedings of
ASCE Pipelines 2018 “Revitalizing Global Underground Utility Infrastructure”.

ABSTRACT
This paper describes the implementation of an automatic control system based on operational
optimization, for city of Toronto and York Region Water Transmission System. The new
automation system has been in operation since November 2015. The water supply system,
serving a population of 3.4 million, is the largest in Canada and one of the largest in North
America. The system consists of treated water pumping at four filtration plants, 18 pumping
stations, 15 reservoirs/tanks, 126 pumps (up to 1,865 kW (2,500 hp)), and approximately 500 km
(310 miles) of large transmission mains. While the city of Toronto and the region of York
provide the water delivery/service requirements in a cost effective and uninterrupted manner, the
complexity of the water system and the volatility and complex structure of the energy rates,
present opportunities for benefitting from automation and further optimizing operations. As part
of the new automation process, the transmission operations optimizer (TOO) minimizes energy
used and cost of energy, while ensuring fundamental service delivery standards including
pressure, flow, and storage are met. Pre-set minimum (critical) storage levels are not violated.
‘Optimal’ automatic control strategies are achieved for different seasonal, weekday/weekend
demand patterns, as well as when abnormal events occur such as a pumping station or filtration
plant being taken out-of-service. TOO involves water consumption/demand prediction, energy
rate prediction, hydraulic modeling, mathematical optimization, analytical algorithms, data
integration and on-line monitoring of system performance, and energy spot-market rate.
INTRODUCTION
Toronto Water, division of the City of Toronto, provides drinking, wastewater and storm
water services to 3.4 million residents and businesses. It owns CAD$28.3 billion dollars in
infrastructure. Toronto Water is primarily responsible for the operation of the Water System.
Within Toronto Water, the Water Supply unit, consisting of 60 staff and a separate control room
operation, is responsible for the pumpage, storage and transmission of drinking water. The
supply system is a large, complex and integrated system which consists of 4 large water
treatment plants, 500 km (310 miles) of large diameter transmission mains, 18 pumping stations,
15 reservoirs and tanks, and 126 pumping units with a 1,200 MLD (317 MGD) average
consumption distributed over 6 pressure zones & 13 pressure districts. This trunk water main,

transmission system, then supplies the local distribution water main system. The Water Supply
unit also supplies water to a significant portion of southern York Region.
Prior to the implementation of TOO, the Water Supply system within the City of Toronto
was essentially manually operated. Manual operation consisted of an operator, guided by various
standard operations and maintenance procedures, determined pump start / stop and run durations.
This methodology was utilized to manage routine and non-routine situations. Non-routine
situations include pumping units out of service, hydro failure, water treatment plant down time,
etc.
Electrical energy costs make up the most significant portion of the operating budget of an
integrated system of this scale. On average Toronto spends CAD$40 million annually on
electrical energy costs of which CAD$26 million of that is the responsibility of the Water Supply
unit. Over 90% of the energy required for the Toronto-York water system is managed by Toronto
Water.
Energy pricing in Ontario can be volatile and complex since it includes commodity charges
(energy kWh, based on the spot market), demand charges (max kW, kVA) and Global
Adjustment (GA) charges. As a result, the development and utilization of an automated
optimized pumping solution would provide significant savings. This being the case, the City of
Toronto and York Region partnered to develop TOO which provides opportunities to leverage
reservoir storage, automation, energy price predictions, hydraulic modelling and historical data
to create daily station schedules to reduce electricity use and cost. With the implementation of
TOO on November 9, 2015, Water Supply moved from a “computer manual” operation to an
“optimized” automated operation.
Tables 1a and 1b provide data showing the average power for the Water Supply pumping
stations.
ENERGY SAVING OPPORTUNITIES
Transmission Operations Optimizer (TOO) is a custom designed, “real-time", online
software that automatically determines optimal pumping control strategies. TOO will minimize
electrical costs at all times: amidst electrical power cost variations, planned / unplanned
equipment downtime, demand / storage variations; while maintaining customer service standards
for pressures, flows, and reservoir storage levels. TOO inputs consist of real-time weather data,
Hydro (power/energy) rates, SCADA data and past water demand data which are used by
sophisticated software algorithms in the “Smart Real-time Water System Control System” [1] to
generate an output control strategy, displayed as pump schedules and reservoir profiles. These
optimal strategies are reviewed and approved by a Water System operator. The approved strategy
is then automatically transferred directly to SCADA. See Figure 1. The pumps then start / stop in
accordance with the strategy.

Real-time weather data contains the latest current conditions and 7 day forecast details from
Environment Canada. Hydro real time and predicted rates inputs are obtained from the
Independent Electricity System Operator (IESO). SCADA real time and historical inputs are
obtained from City and Region network data servers. Historical demand data is also obtained
from the network data servers.
In general, TOO runs as follows [1] (See Figure 2):

includes, but is not limited to, reservoir levels, equipment out-of-service, equipment
auto/manual modes, and production costs

3. Determine potential optimal strategies in conjunction with hydraulic & quality model
4. Analyze results to check strategies
5. If results are acceptable, apply strategy to SCADA systems, otherwise re-run Optimizer
with changes to the constraints.
Figure 2. Transmission Operations Optimizer (TOO) Architecture
OPTIMIZER AND PUMP CONTROL
TOO operation ("a run") can be initiated manually by the operator or automatically based on
scheduled time and on various “triggers". (See Figure 3). These triggers are based on equipment
status changes, storage profile deviations or energy rate deviations. Once an optimizer “run” is
complete and a new strategy (pump schedule and reservoir profiles) (see Figure 4) is available,
the operator reviews the strategy (primarily pump schedule) to ensure that the pumps and the run
times appear reasonable. Additional information is available for review, including predicted
reservoir profiles, if required. Once these conditions are met, the operator “accepts” the solution
which allows the schedule to be transferred automatically from the TOO system to SCADA. If a
proposed schedule is declined by the operator, the operator can change some parameters (such as
limits), and then re-run TOO to provide an alternate solution based on new system conditions.
Note that this alternate solution will be optimal with respect to the latest conditions. The option
also exists for specifying manual pump start / stop times at individual pumping stations if
required.
SYSTEM IMPACTS
TOO pumping strategy tends to achieve an increase in flow rate when energy costs are low
and conversely decrease flow decreases when energy costs are high. (See Figure 5)
TOO pumping strategy results in an overall change in reservoir storage profile patterns. For
example, storage levels tend to be lower and vary over the course of a week from the period prior
to TOO usage (see Figure 6).

CONCLUSION / BENEFITS
TOO was launched on November 9, 2015. Since then, energy savings have been
approximately 8 Million kWh (27,315 Million Btu) per year. This is equivalent to 5,000 tonnes
(5,512 tons) of Carbon Dioxide emissions not pumped into the environment. This equates to:
20 Million km (12.4 Million miles) driven by an average passenger vehicle, or
1,200 passenger vehicles driven for one year, or
Annual electricity use for 800 homes, or
13,000 barrels of oil consumed.
Figure 3. TOO Run Triggers and Controls
Energy cost saving obtained is approximately CAD$1.38 Million/Year. Figure 7 shows the
reduction in actual energy per unit of water pumped. Future improved costs savings are expected
as TOO function and water system facility infrastructure and practices are enhanced. Results
have been verified by City, Toronto Hydro and third party reviewers. As a result of TOO, Water
Supply has received incentives, recognition and awards such as:
Toronto Hydro Save on Energy Award of CAD$1,628,595.00 in 2016
City of Toronto City Manager's Award 2016
Recognition in the Environmental Commissioner of Ontario – “Every Drop Counts”

ABSTRACT
The Lake Huron Water System and Elgin Area Water System are regional water systems that
supply water to 15-member municipalities serving approximately 500,000 people across 5,000
square kilometers (1930 square miles) of southwestern Ontario. Their advanced and innovative
asset management plan and asset management program are based on a customer level of service
approach and risk mitigation framework which, in part, relies on condition assessments and
operational data to determine proactive, cost-effective, and timely investments in this regionally
significant infrastructure. Since their construction 50 years ago, the 1200mm (48-inch) primary
transmission pipeline on the Lake Huron system has suffered 4 failures and is entering a critical
stage in its life-cycle. Water pipeline operators have many technologies and techniques that
enable them to determine the condition of their conveyance assets, their deterioration rate, and
probability of failure. By quantifying and monitoring damage on their assets, the Lake Huron
water system is able to categorize the structural damage found, allowing them to prioritize their
rehabilitation program, and allocate funds on a systemic basis. This approach to pipeline asset
management has supported the extension of the serviceable life of critical infrastructure by
identifying urgent repair needs, improving maintenance, and capital planning. The program
demonstrates that by collecting quantitative data and incorporated into an effective asset
management program, significant amounts of money for infrastructure renewal can be saved
while minimizing service disruptions.
INTRODUCTION
The Lake Huron Water System and Elgin Area Water System are regional water systems that
supply water to 15-member municipalities serving approximately 500,000 people across 5,000
square kilometers (1930 square miles) of southwestern Ontario.
The Lake Huron Primary Transmission Main is a 1200-millimetre (48-inch) diameter
pipeline carrying potable water 47 kilometres (29 miles) from the Water Treatment Plant on
Lake Huron to the City of London, and seven other municipalities within the region. The Lake
Huron Primary Transmission Main was constructed in 1965 and consists of prestressed concrete
cylinder pipe (PCCP).
The Lake Huron Primary Transmission Main has experienced 4 previous failures – in 1983,
1988, 2010 and 2012. As a response to the failures, the Lake Huron Primary Water Supply
System (LHPWSS) undertook a pipeline twinning program to create redundancy and operational
improvements in the system. Construction on the twin line occurred in 1996 and 2013, with 28
