How Your Water is Treated

LAkE TO LAkE APPrOACH FOr SAFE DrInkIng WATEr

STEP 1: Source Water Our drinking water starts with the world’s largest source of fresh water, Lake Superior. The intake for the plant is located nearly 1 km from the shoreline and is positioned at a water depthofapproximately18metresandrestsapproximately9 metres above the lake bottom. The depth of the intake protects it from debris entering from the bottom of the lake and from the water surface.

STEP 2: ScreeningThe raw water enters the plant through the intake. Travelling screens remove debris and prevent particles from entering the plant. The raw water is stored briefly in the wet well. The screens are similar to common household window screens, although they are made from stainless steel.

STEP 3: Filtration The water is then pulled through the ZeeWeed membrane filtration system using vacuum generated from pumps. Hollow fibre ultra-filtration membranes use gentle suction to filter impurities from the water.


STEP 4: DisinfectionThe clearwell is used for primary disinfection as described by the Ministry of the Environment and Climate Change. Sodium hypochloriteisaddedtothewaterintheclearwellmixingchamber. The clearwell uses a baffling system to allow the sodiumhypochloritetomixwiththewater.Thiscreatesalongcontacttimeorsoakingtimeforthewatertomixwiththe hypochlorite. Contact time is a measurement of the concentration of the sodium hypochlorite multiplied by the time travelled in the clearwell.

STEP 5: StorageThe clean, safe, disinfected drinking water is then stored at the plant in two underground storage tanks to keep the water cool and fresh, awaiting delivery to customers’ taps. Each reservoir can hold over two million litres of water.

STEP 6: Water DeliveryWater is pumped from the storage reservoirs into the distribution system by high lift pumps. Some of the water is delivered directly to customer taps and some is delivered to one of five storage facilities within the distribution system.

STEP 7: Environmental ProtectionWastewater from the membrane filtration process is piped to the Atlantic Avenue Water Pollution Control Plant for treatment before being returned clean to Lake Superior.

:Find your pressure zone and read on page 9 how water is delivered to your area.


From the Plant to Your Tap

Thunder Bay’s water distribution system is divided into eight pressure zones (see map opposite page). High lift pumps move the treated water from the plant into the distribution system. The water storage facilities and pumping stations regulate water pressure within the distribution system.

Water can be redirected through the distribution system when needed. The system is made up of the following components:

Standpipe – Above-ground water storage facility providing pressure by water column height

Reservoir – Large volume in-ground water storage facility

Pumping Station – Pumps water from one zone into another zone and can be used to increase water pressure to an area

Water Pressure Zone – Areas where a minimum and maximumwaterpressurecanbeexpectedinwaterdistribution system

Zone 1n The reservoirs at the Bare Point Water Treatment Plant store water for this zone and pump it into this area as needed. The Duke Street reservoir also provides water storage for this zone.

Hodder Zone The Hodder Standpipe stores water for this zone. Water is pumped from the Bare Point Water Treatment Plant to the Hodder Pumping Station. This station supplies water to the Standpipe as needed.

Zone 2AThe Duke Street reservoir stores water for this zone. It was added to increase and maintain water pressure for this area.

Zone 2nThe McIntyre reservoir stores water for this zone. Water is pumped from the Bare Point Water Treatment Plant through the Chamberlain Pumping Station to this zone.

Zone 3n The Hazelwood Standpipe stores water for this zone. Water is pumped from the Bare Point Water Treatment Plant through the Chamberlain Pumping Station to the McIntyre reservoir. The McIntyre Pumping Station supplies water to the Hazelwood Standpipe.

Zone 1SThe rockcliff reservoir stores water for this zone. Water is pumped from the Bare Point Water Treatment Plant through the Vickers and James Street Pumping Stations filling the rockcliff reservoir and supplying water to the area.

Zone 2S Water is pumped from the Broadway Avenue Pumping Station to this zone. Water is drawn from the Zone 1S water distribution system, which includes the rockcliff reservoir.

neebing ZoneWater is drawn into this zone from the Zone 2S distribution system. The neebing Booster Pumping Station increases water pressure for this zone.

Water Quality Monitoring We are serious about drinking water quality. In 2018, ThunderBayresidentsreceivedexcellentqualitydrinkingwater. Samples are taken and evaluated according to the Ministry of the Environment, Conservation and Parks regulations. Water quality is monitored at the treatment plant every minute of every day by operators and on-line instrumentation. In addition, an independent certified laboratorytestedapproximately2,000samplesforpotential contaminants. The total number of water samples taken in 2018 was more than 29,000.

Our testing program is fully compliant with Ontario’s Drinking Water regulations.


Operator Certification and Training

Under the Safe Drinking Water Act (SDWA) all Ontario Drinking Water Systems must be categorized by type of system and classification level. The City of Thunder Bay’s Bare Point Water Treatment Plant and Distribution Subsystem is categorized as a Level III Treatment System and a Level IV Distribution System.

Section 12 (1) under the SDWA requires that no person shall operate a municipal drinking-water system unless the person holds a valid operator’s certificate issued in accordance with the regulations.

The certification program establishes occupational standards for operators and water quality analysts. It is intended to give greater assurance of safe drinking water to the residents of Ontario through ensuring thatoperatorshavetheeducation,experienceand

knowledge to perform their responsibilities effectively.

Water Distribution (WD) and Water Treatment (WT) Certificates must be renewed every three years. In order for operators to maintain a WD or WT certificate they must complete a minimum of 150 hours of training over the three year period; this includes 42 hours of Director Approved Training which involves completing anexamwithaminimumof70percenttopass,108hours of Hands on Training pertinent to WD or WT and completion of the Provincial Mandatory Course. In 2018, water operators working in the Environment Division completed a total of 6563 hours of training.

In order to obtain a WD or WT certificate an operator mustmeetthefollowingeducationandexperiencecriteria:

Our Commitment to Continuous Improvement

Capital Asset ManagementThe City of Thunder Bay’s water system is comprised of significant assets (2016 estimated replacement value: $608 million), to ensure the delivery of safe drinking water to all. These assets include: Bare Point Water Treatment Plant, 1 lab, 1 standpipe,4 reservoirs, 7 water pumping stations, 8 water pressure zones, over 700 kilometres of watermains, and thousands of connections, fire hydrants, access chambers and valves. These assets are referred to as capital.

Asset management plans have been developed for the drinking water system to identify how these assets should be maintained, renewed or upgraded as required. The 2016 Asset Management Plan for the Corporation of the City of Thunder Bay (Version 3) has been prepared as a consolidation of long-range infrastructure strategies and current financial and technical practices, with a goal to maintain, upgrade and operate the City’s physical assets in a cost-effective manner. The strategy for the water system relates directly to the replacement and/or rehabilitation of watermains prioritized based on the age, material type, size, soil conditions, and pressure-related issues.

In 2018, the 20 year Capital Planning Study was updated which focused on a high-level condition assessment for the facility components of the Bare Point Treatment Plant, pumping stations, and the in-ground storage reservoirs and standpipes, resulting in the determination of maintenance and renewal needs up to 2038.

For further details, the 2016 Asset Management report can be found on the City of Thunder Bay website at thunderbay.ca/assetmanagement

Water System Financial Plan UpdateIn 2007, MECP released regulation 453/07 requiring all municipalities to complete a Financial Plan for their drinking water system. City Council approved an update to the 20 year plan in July 2018.

Through the process of updating the plan, the Water Authority set out to achieve the following:

- financial viability- limit overall water costs to consumers- provide safe drinking in short term and long term- fund the long term capital plan- achieve full cost recovery over the long term- maintain current service levels

The plan focuses on achieving a balance between maintaining the water system in a safe and effective manner, whilelimitingexpendituresandwaterrateincreases.

Pilot Plant and Lakehead University research Agreement UpdateThe pilot plant at Bare Point was re-started in 2018 to support research work being done in-house and in collaboration with Lakehead University. The effect of cold water on membrane filter performance is being studied, as is the potential for enzyme based cleaners to be used in place of more harsh chemicals for membrane cleaning. research related to the cold water study conducted at Lakehead University was published in “Water research, A Journal of the International Water Association” in 2018, and the results of the pilot plant workareexpectedtobepublishedin2019.LakeheadUniversity also conducts research at Bare Point on the identification of defects in pumping equipment, including the development of smart sensors for this, and signal processing techniques for vibration analysis. Some of the results from this work were published in 2018 in “Measurement Science and Technology” and in the “International Journal of Mechanical & Mechatronics Engineering”. This work has the potential to save maintenance and repair costs through the early identification of mechanical component wear.

Our Commitment to Continuous Improvement Corrosion Control Program For Lead

In 2007, the Ministry of the Environment, Conservation and Parks (MECP) initiated the Lead Action Plan to address concernsofleadindrinkingwateracrosstheprovince.Studieshaveshownchronicexposuretolead,evenatlowlevels, can have health impacts. Of particular concern are the neurodevelopmental effects impacting learning and memory on developing fetuses and young children.

Since 2007, the City of Thunder Bay continues to participate in the Lead Action Plan by testing for lead in drinking water in various private plumbing residences throughout the community. In accordance with Schedule 15.1 of the Ontario regulation 170/03 under the Safe Drinking Water Act (SDWA 2002), the City developed a Corrosion Control Plan as part of the Lead Action Plan. The primary focus of the Plan includes lead service replacement, public educationandtheadditionofsodiumhydroxide,apHadjustingchemicaltotheCity’sdrinkingwaterattheBarePointWaterTreatmentPlanttoreduceleadlevelsinprivateplumbingsystemsacrosstheCity.City-widepHadjustmentcommenced in early 2018 once public notification was complete.

**The goal is to sample as many residential and non-residential (commercial) taps with known or suspected lead service lines as possible at the same recurring locations in every sampling period**


A total of 420 plumbing and 146 distribution water samples were taken in 2018. Various plumbing locations were sampled throughout the City, 23 of these locations provided lead sample results for both pre addition as well as postadditionofsodiumhydroxide.WhencomparingtheleadresultsfortheselocationsthereisasignificantreductioninleadfoundatthetapaftercommencementofpHadjustmentofthedrinkingwater.

Lead Service Line replacement

The City of Thunder Bay’s Water Authority continues to review the number of lead service connections, both publiclyandprivatelyowned.ItisestimatedthattheCityhasapproximately6996publiclyownedand9635privately owned lead service connections. Publicly owned lead service lines are typically replaced during watermaincapitalprojects,butcanbereplacedaswellunderthePriorityLeadReplacementprogram.

Prior to a watermain being replaced (performed by a private contractor under a capital contract), the City notifies the homeowner to discuss the replacement of the private portion of their service line. Prior to the City portion being replaced under the capital contract, testing of the tap water in the private residence is requested to provide a baseline lead result. If a homeowner wishes to have the private portion of their service line (property line to water meter) replaced at the same time as the City portion, they must arrange with the on-sitecontractortodotheworkattheirownexpense.Aplumbingpermitmustbeobtained,andaplumbermustcomplete the final connection.

Once the lead service line is partially or completely replaced, it is highly recommended the tap water be tested again to ensure lead levels are reduced. Testing is free and arranged through the City by calling 684-3568.

On streets not scheduled for watermain renewal, homeowners may arrange with a contractor to replace

the privateportion(propertylinetowatermeter)oftheirleadservicelineattheirexpenseandtheCitywillfundandcompletetheworkextendingfromthepropertylinetothewatermain.Itispreferredthatthehomeowner contact the City to arrange for lead testing prior to the replacement of their private portion to obtain a baseline lead result. The homeowner must obtain the required plumbing permit, hire a plumber for the final connection and have all final inspections done. Once this is complete, the homeowner will, in person, complete an application with the City of Thunder Bay Engineering Division. The homeowner also needs to bring the completed inspection report. The homeowner completes the final restoration of their property, and the City will restore City property. The City processes such requests in sequence, the priority given to cases of elevated lead levels according to drinking water testing. For information on drinking water testing, call the City at 684-3568 or visit www.thunderbay.ca/leadpipes.


If your home has a lead service line, replacing the entire service pipe is the best way to ensure no lead is getting into your water.

Partial lead service Replacement:

research indicates when lead service lines are disturbed, the amount of lead found in consumer’s drinking water may increase for weeks to months. In the event a service line is partially replaced by the City or the homeowner, it is strongly recommended private plumbing lines be flushed prior to consumption.

After a partial replacement of a lead service line has been completed, the following steps should be taken prior to consuming the water from your tap.

1. remove and clean your faucet aerators from all cold water taps in the home.

2. Beginning in the lowest level of the home, fully open the cold water taps throughout the home.

3. Let the water run for at least 30 minutes at the last tap you opened (top floor).

4. Turn off each tap starting with the taps in the highest level of the home. Be sure to run water in bathtubs and showers as well as faucets.

5. Do not consume tap water, do not open hot water faucets or use icemaker or filtered water dispenser until flushing is complete.

6. replace cleaned aerators.

In addition to the above instructions, a daily mini-flush consisting of a 5 minute displacement flush is recommended for 6 months post partial replacement of a lead service line. Aerators should be cleaned regularly to remove any particulate lead that may have accumulated.

It is also recommended after a partial or full lead service line replacement the water be tested to ensure lead levels at the tap are reduced. This testing is free and arranged through the City by calling 684-3568.


How does lead get into drinking water?The raw water from Lake Superior and drinking water supplied from the water distribution system have little or no lead present. However, lead is occasionally found in the water service pipes and the plumbing in homes, which can dissolve into the water supply from these sources. Lead can enter tap water through corrosion of plumbing materials like leadsolder,fixturesorleadpipes.Chromeorbrassplatedfaucetsandfixturescanalsoleachleadintodrinking water.

How do i determine if i have lead pipes in my home?Lead piping was used in older homes, usually built before 1952. Lead pipe is easy to bend, dullish grey in colour and leaves a silver mark when scratched on another surface.

What should i do if i live in a house with a lead service pipe or plumbing?Flush. When water sits in the lead service pipe for long periods of time it absorbs more lead than when running. Waterthathasstoodinthetapformorethansixhoursshould not be used for consumption. Before using water for drinking or cooking, let the water run from the cold water tap for up to five minutes. To avoid wasting water, take a shower, run the washing machine, or run the dishwasher to clear the pipes. Once you have let the water run, fill pitchers, kettles or pots for drinking or for food preparation during the day.

Who can i call to arrange to have my water tested?If you are concerned about lead levels in your water, contact the City of Thunder Bay, Environment Division at 684-3568 to arrange to have your water tested.

Does lead in drinking water pose a health risk? Lead is a common metal found in the environment in air, soil, household dust, food, certain types of pottery and water. Lead can pose a significant risk to your health if too much enters your body. The greatest risk is to young children and pregnant women. Lead exposureisaworld-widehealthproblem.Ifyouhave,orsuspectyou have a lead water service, alternate sources of drinking water should be considered for young children and pregnant women.

How can i reduce my exposure to lead in my drinking water?Therearemanystepsyoucantaketoreduceyourexposuretolead in drinking water, but if you have a lead service line, the best step you can take is to have it replaced. In addition you can· Have your water tested for lead free of charge· run your water to flush the lead out – if it hasn’t been used for several hours, run the water for 3-5minutes to clear most of the lead from the water. · Always use cold water for drinking, cooking and preparing food – never cook with or drink water from the hot water tap.· Do not boil water to remove lead – boiling does not reduce lead concentrations

Lead: Frequently Asked Questions

· Periodically remove and clean faucet screens / aerators – while removed run water to eliminate debris·Identifyandreplaceplumbingfixturescontaining lead. Brass faucets, fittings and valves may leach lead into drinking water.

· Consider investing in a home water treatment device (filter system). When purchasing a water treatment device, make sure it is certified under nSF/ AnSI 53 to remove lead. Search for certified products at nSF International (800-nSF-8010) or Water Quality Association (630-505-0160).

What is the City doing to reduce lead?The City of Thunder Bay strives to reduce overall lead serviceconnectionsandfixtures,provideongoingwatermain flushing/cleaning, increase overall water quality awareness and provide free testing for lead at the tap.

What can you do to help? If you have a lead service, please contact the City to arrange for testing. A qualified licenced operator will come to your home and test your tap water free of charge. You will be provided with the results of the testing. You can also help by replacing your lead service line – reducing the amount of lead. If you replace your service line, follow the flushing instructions post replacement and contact the City for testing. For the public lead service line to be replaced, visit the Engineering Division in person to fill out an application to start that process. Once this full replacement is complete, arrange for testing through the City to ensure lead levels have been reduced. Free testing can be arranged by contacting the City at 684-3568.

The City is also looking for volunteers to help us in determining the effectiveness of the corrosion control plan. This would entail allowing one of our certified operators to take samples in your home on a monthly basis. We are requesting that homeowners with a known or suspected lead service line or lead solder contact us at 684-3568. Our certified operators will contact you and make arrangements to obtain samples at your convenience. You will be provided copies of all test results and there is no charge for the sampling and testing.


Protecting Drinking Water at Your Tap

Cold water is best for drinking, cooking and preparing food. Hot water is meant for washing dishing, laundering clothes and bathing. To protect the quality of the drinking water coming out of your tap you need to maintain your faucets and filter system (if you have one installed).

Make sure your sink is cleaned regularly and leaking faucets are repaired. Sediment can also build up on the screen of your faucet, following the instructions below to clean your faucet aerator.

Faucet Aerators (also called screens)*

routinely clean faucet screens. Sediment and metals can collect in the faucet screen located at the tip of your faucets. replace screens that are in poor condition. new screens are available at local hardware stores.

To clear the faucet screen of debris:

1. Unscrew the screen.

2. Separate the individual parts.

3. remove any sediment (mineral or rust build up) on the screen and other parts. If necessary, soak the parts in white vinegar for a few minutes and scrub with a brush.

4. reassemble the screen parts and re-attach to faucet.*Modified from DC Water https://www.dcwater.com/sites/default/files/household_water_quality.pdf

Water Treatment Devices (Filter Systems)If you own a filter system for your home or use a pitcher filter, make sure you follow the manufacturer’s instructions for maintenance on the system and replace filters according to the manufacturer’s instructions.

Prevention Program The City of Thunder Bay is dedicated to protecting the quality of our drinking water. In order to manage the potable water supply and minimize risks to public health, the Development Services Department and Environment Division – Water Authority have implemented a Backflow Prevention Program. Work is ongoing with property owners, certified testers and plumbing contractors to identify cross-connections, and advise where backflow prevention devices are required to protect the public potable water supply. For more information on this program, contact the Building Division at 625-2574.


Source Water Protection

For the Lakehead Source Protection Area, the Source Protection Plan sets out policies to protect sources of municipal drinking water. It determines how drinking water threats will be reduced, eliminated or monitored, who is responsible for taking action, timelines, and how progress will be measured.

The Plan specifically applies to municipal residential drinking water sources (Wellhead Protection Areas and Intake Protection Zones). no threats have been listed in the Assessment report for highly vulnerable aquifers (HVAs) or significant groundwater recharge areas (SgrAs) within the Lakehead Source Protection Area; therefore, no policies have been developed in these areas.

Section 22 of the Ontario regulation 287/07 lists these SourceProtectionPlanobjectives:

1.Toprotectexistingandfuturedrinkingwatersourcesin the Lakehead Source Protection Area.

2. To ensure that in all areas where a significant drinkingwaterthreatcouldexist,that:a)Iftheactivityisoccurring at the time the Source Protection Plan takes effect, the activity ceases to be a significant drinking water threat; and b) The activity never becomes a significant drinking water threat.

The Lakehead Source Protection Plan, released in 2013 by the Lakehead Source Protection Committee, is available at www.sourceprotection.net.

Protecting Our Waterkeep it SuperiorAlthough we live on the doorstep of Lake Superior, we must use the resource wisely! Less than one per cent of the total water on the planet is available to us as fresh water. Only a portion of that is renewable fresh water. If all the earth’s water were stored in a 5-litre container, available fresh water would not quite fill a teaspoon. The World resources Institute defines renewable fresh water as “salt-free water that is fully replaced in any given year through rain and snow that falls on continents and islands and flows through rivers and streams to the sea.” Canada contains 6.4 percent of the world’s annual renewable fresh water.

ObjectivesandScopeoftheSource Protection Plan


Plastic Pollution Prevention

Plastic waste degrades over time into microplastics, with significant impacts on lake ecosystems. Over 22 million pounds of plastics are dumped into the great Lakes each year. Much of this is a result of single use plastics such as drinking straws, shopping bags, take-out containers, disposable cups and utensils; all items that can be avoided with readily available alternatives.

In 2018, in efforts to eliminate and prevent plastic pollution, EcoSuperior hosted a citizen science event consisting of a shoreline clean-up/microplastic survey held on October 12, 2018 at Chippewa Beach with the Environmental Technician students at Confederation College. The students, with guidance from EcoSuperior Program Coordinators, performed two forms of analysis of samples collected at Chippewa Park. The most common garbage found in this analysis were tiny plastic pieces (792), followed by other plastics and foam packaging (455). The total weight of all debris collected was 1.364 kg.

EcoSuperior continued its efforts by continuing the implementation of The Last Straw Thunder Bay campaign. The campaign educates the public on the environmental impacts of single-use plastic straws and encourages them to ask partners in the food service industry to make a commitment to limit their use. The campaign also supports action by food service providers, mainly restaurants and cafeterias, in reducing their use of disposable plastic straws. To date, over 50 local restaurants, food

service businesses and schools have signed onto the campaign to reduce their use of plastic straws either through implementation of a “straws by request policy”, switching to alternate products (paper or reusable straws) or through the distribution of educational material.

Locations who signed on to the campaign received signage, table cards with customer surveys and a supply of paper straws to test in their operations. 254 surveys have been submitted by customers at participating restaurants. The results are as follows:

a. 73% of respondents prefer beverages to be served with no straws, 12% prefer paper straws, 10% reusable, 4% prefer plastic

b. 99% of respondents support actions to reduce the use of plastic straws

c. 92% of respondents believe The Last Straw Thunder Bay will increase awareness of plastic pollution in Lake Superior.

How do we know our drinking water is safe? The Ministry of the Environment and Climate Change sets stringent monitoring requirements for drinking water. Water quality is monitored 24 hours a day, seven days a week. Customers can have confidence that their water treatment plant has highly effective water treatment and quality assurance processes in place to remove bacteria and other harmful substances from the water.

What is a Water Fill Station? Water fill stations are locations where residents may purchase City water. There are two self serve residential water fill stations that are open 24 hours a day, seven days a week. A “Fob” must be purchased in advance. The stations are located at the corner of Hwy 61 and Mount Forest Boulevard and on Valley Street at Hutton Park Drive. For more information on the stations or where to obtain a “Fob”, please contact 625-2195.

Does the Backflow Prevention Program apply to residential homeowners? The Water Works By-law does not require single-family dwellings to install backflow prevention devices unless the Water Authority determines that the property is a high risk. However, homeowners can take steps to protect the drinking water system.

Indirect cross-connections such as a hose with one end immersed in a swimming pool, laundry sink, fish tank, bucket, etc., can result in contaminated water being pulled back into the drinking water system. Wherever possible, install backflow prevention devices on outside water taps, boilers and sprinkler systems to protect the quality of the public drinking water supply and the quality of the water in your home.

What is a remote meter reading device? remote reading devices can be installed for a water meter which will allow the meter to be read from outside your home. These devices provide accurate water consumption readings without requiring the homeowner to be home or the need for a homeowner to call in quarterly meter readings. Upon request, these devices can be installed at the cost of the homeowner. For further information on installing a remote device, please contact the Environment Division at 474-4817.
