1.1 Overview

Through 2017, EPCOR Water Services Inc. (EWSI) continued to satisfy all water

demand requirements while meeting our strict water quality criteria. Despite

continued growth of the service population, total demand in 2017 fell as

compared to 2016 and 2015. This could be a result of cooler, wetter summer

conditions but also decreasing demands from the industrial and commercial

segments, perhaps indicating an impact of the economy. Overall residential per

capita and total per capita values also continued to trend downward primarily due

to the installation of water efficient fixtures and appliances.

Rossdale and E.L. Smith WTPs were converted from Direct Filtration (DF) to

conventional treatment on February 18th as very mild temperatures resulted in

the upstream creeks starting to flow. Some odours were detected and carbon

was turned on for 8 days. As the temperatures decreased towards the end of

February, Rossdale was able to be converted back into direct filtration mode on

March 10 until March 21, where warm temperatures again brought spring runoff

conditions. Though colour peaked at 83 TCU, spring runoff did not bring any

significant taste and odour concerns and carbon was finally turned off on April 7.

There were two rainfall/mountain runoff events near the end of May and mid-

June, which resulted in peak turbidities of approximately 550 and 1300 NTU,

respectively. These events were handled well with no production problems

encountered. There were no other significant rainfall events affecting water

quality the rest of the year.

While raw water quality was reasonably stable, there were a couple of significant

infrastructure failures that impacted production at E.L. Smith. In late 2016 and

again in the fall of 2017, leaks were discovered on one of the two pipelines which

convey raw water from the low lift pumphouse to the WTP. While each leak was

ultimately repaired, production was impacted due to the requirement to shut

down the pumphouse feeding the line. The fish return pumps in one of the lowlift

pumphouses at E.L. Smith WTP also failed without warning and had to be

repaired offsite.

Edmonton WTPs continued to focus on optimizing chemical dosing and

minimizing release of water treatment plant solid residuals to the NSR. A new

filter polymer (LT-7995) was implemented at both WTPs as pilot trial tests

demonstrated improved filter run times and effluent quality, particularly during

direct filtration. A new grade of fluoride (hydrofluosilicic acid) was also

implemented at both WTPs. The new product had much lower levels of impurities

than the previous product.

As previously mentioned, fall water quality was very good and the Rossdale WTP

was able to convert to direct filtration on September 5 for 14 days before

returning to conventional mode after a moderate increase in turbidity and colour.

It was able to revert to direct filtration mode on October 5 followed by E.L. Smith

on October 18 (with a short transition to conventional mode between October 31

and November 10). Overall, the WTPs were able to reduce total solids

discharged to the NSR by 25% during the months of January, February,

November and December 2017 compared to baseline conventional operation. In-

stream sampling and monitoring of WTPs clarifier waste stream discharges to

NSR continued in 2017 to further understand the impacts of residuals discharge

on the river environment.

There was one AEP approval contravention at the WTPs in 2017, as detailed in

Section 1.4 Summary of Violations and Notifications. WTPs continue to improve

the integrated safety and environmental management system in accordance with

the ISO14001:2004 and OHSAS 18001:2007 standards. The WTPs and

reservoirs were re-registered to OHSAS 18001:2007 and registered to the new

ISO 14001:2015 standard in November 2017.

EWSI continued to upgrade the water treatment plants and the reservoir assets.

Total expenditures in 2017 were approximately $29.2M. Some of the major

projects are as follows:

• E.L. Smith Solar – preliminary feasibility studies and public consultation

occurred in 2017 with the intent of having a 12MW solar farm installed

adjacent to the E.L. Smith WTP by the end of 2019;

• Rossdale & E.L. Smith - Filter underdrains and the air scour system were

upgraded at Rossdale and filter media topped up at E.L. Smith on a number

of filters. These projects will continue in 2018;

• Roofing upgrades were carried out on various buildings at E.L. Smith and

Rossdale, as well as reservoir concrete restoration work at Papaschase,

Kaskitayo and E.L. Smith cell #1 reservoirs;

• A new small booster pumping station in the Laurel neighborhood of SE

Edmonton was started in late 2017, to be completed in early 2018.

In 2017, Water Distribution and Transmission repaired 242 water main breaks on

the distribution system in Edmonton, with the majority of main breaks occurring

on cast iron pipes. While this number is the lowest number of main breaks

experienced since 1961, the trend of a higher proportion of breaks occurring on

larger diameter mains continued. The general trend of decrease in water main

break activity continued and this improvement in overall reliability of the water

distribution system can be attributed to the water main replacement programs as

well as the use of more reliable pipe materials in both replacement and new

water main construction.

In 2017, the Uni-Directional Flushing program completed flushing and valve

exercising in about 36% of Edmonton (2,505 runs).This program is now a six-

year cycle with area prioritization emphasis placed on water quality parameters,

percentage of Cast Iron Mains, and the relative success of the previous flush.

The transmission valve inspection program is ongoing.

EWSI continues to provide water and wastewater services and expertise to

numerous communities in Alberta, British Columbia, Regina, as well as industrial

sites in Fort McMurray and British Columbia’s Elk Valley.

As we move into 2018, we will continue to focus our efforts on the production of

and distribution of high quality water, customer satisfaction, protection of the

environment, workplace safety and cost effectiveness. We will continue to ensure

our customers receive best value for the services we provide them. More detail

on our progress towards meeting our EnviroVista Stewardship community will be

included in our annual EnviroVista report, which will uploaded to epcor.com by

June 30th, 2018.

Number

ENV-01350

EPCOR crew was replacing defective valve 9101 in the vicinity of 93rd street and 65th avenue in Edmonton. This was a planned maintenance event; however, a complete shutdown of the water line was not achieved. When the valve was cut out and pulled from the excavation, potable chlorinated water was released. The water filled the excavation and flowed down the street to a catch basin. Dechlorination pucks were immediately put into the excavation to dechlorinate the water as it was released. As the weather was very cold at the time and some catch basins were frozen the water proceeded down into the nearby Mill Creek ravine. Water continued to flow between 09:30 am until 2:00 pm when the main was shutdown.

ENV-01365

On January 31st, during quarterly sampling and testing, waste stream 6 was found to have a chlorine residual between 0.20 mg/L-0.30 mg/L at the Rossdale Water Treatment plant. A contractor was working in clarifier C2-2 and its effluent flume to perform structural repairs. Operations had re-directed the drain of a water quality analyzer board (which sits next to C2-2) to C2-2 main drain during the repair. However, dechlorination pucks were not checked and replenished during this period of time, resulting in release of chlorinated waste via Waste Stream (WS) #6 to the North Saskatchewan River (NSR). It appears that approximately 10 minute long discharges were occurring 6 times a day between January 17 and 31. The total volume of the potentially chlorinated release over the 14 day period from January 17 to January 31 is estimated to be approximately 140 m3.

Lab personnel was contacted by Alberta Environment and Parks and Alberta Health for a positive result for total coliforms at the Prov Lab for a sample submitted by our sampler as part of the random distribution monitoring program. The sample was collected at the Fire Station #14 located at 7314 - 144 Ave. EPCOR Dispatch was contacted to resample. Five resamples were collected as per the AEP Protocol for Failed Bacteriological Results. Chlorine and turbidity were all within normal operating ranges. Total Coliform and E. coli were negative. It was suspected that the normal disinfection procedure that was followed was not sufficient to remove levels of contamination that the utility tap might have had.

PH-00572

As part of our random distribution system monitoring, a sample collected at a City of Edmonton Fire Station was submitted to Prov. Lab. for analysis and came back positive for total coliforms. EPCOR sent our full time sampling Technician to resample. Four resamples were collected as per the AEP Protocol for Failed Bacteriological Results. Chlorine and turbidity were all within normal operating ranges. Total Coliform and E. coli were negative. It was suspected that the normal disinfection procedure that was followed was not sufficient to remove levels of contamination that the utility tap might have had.

Water sample taken from a hydrant replacement H8678 came back Total Coliform positive. Following AEP’s Protocol for Failed Bacteriological Results resamples were collected - upstream, downstream and at the original site. The result was Total Coliform positive even though Chlorine and turbidity were within normal range. One 1 of 4 results from the resamples failed with a TC positive result on the left cap of the replaced hydrant. Resample results were reported from the lab Manager to AEP hotline and determined although this was a second positive it is not a violation, it is considered a contaminated sample point.

PH-00596

On Saturday June 17 there was a temporary shutdown to install a new hydrant on an existing watermain. After the construction work was completed the main was back in service and we began to flush out of the new hydrant. After approximately 45 minutes of flushing an in-service sample was taken. This sample tested for Total Coliform. Chlorine and turbidity were within normal ranges. This hydrant was then taken out of service. Following AEP’s Protocol for Failed Bacteriological Results resamples were collected - upstream, downstream and at the original site. All had chlorine and turbidity within normal operating ranges and all bacteriological results were negative for total coliform and E. coli.

18-JUN-17 325861

ENV-01501

Water Trouble responded to water discharging out of a catch basin adjacent to the Mill Creek Ravine on June 19th. Initially, this water was thought to be the result of a mainbreak and a release of chlorinated water was reported to Alberta Environment and Parks. De-chlorination equipment (pucks) and erosion control was deployed at the scene. Upon further investigation it was determined that the water surfacing from the catch basin was de-chlorinated (zero chlorine) and therefore was very unlikely to be attributed to a mainbreak. The EPCOR Water Infrastructure Project completed a de-chlorination and flush of the isolated previously super chlorinated section of new 300mm PVC pipe at 91 Street and 84 Avenue, two blocks away from the discharging catch basin on June 19, 2017. Previous flushing activities (two prior flushes) had taken place at this site, with no issues. As previous flushes in the area did not result in any surcharging water, it was suspected that there was an issue with the combined sewer on 84 Avenue. City of Edmonton Drainage Operations was contacted on June 20, 2017 and completed an investigation (camera and HydroVac) of the sewer line. The City found a sewer plugged with gravel in the immediate area of 9323 84 Avenue that is the root cause of the discharge. The plugged sewer caused the backup of water onto the street and overflow down into the Mill Creek Ravine.

PH-00598

A sample collected as part of our random distribution monitoring program at Fire Station #10 tested positive for total coliforms and E coli. The incident was reported to Alberta Environment and Parks. Following AEP’s Protocol for Failed Bacteriological Results, a set of four resamples was collected - upstream, downstream and at the original site on June 22. These samples were tested at the EPCOR Water Lab. All had chlorine and turbidity within normal operating ranges and all bacteriological results were negative for total coliform and E. coli. A second set of four resamples was collected on June 23. These also tested negative for total coliform and E. coli and were within normal operating ranges for chlorine and turbidity. The cause of the Total coliform and E. coli +ve was determined to be a contaminated sample point.

2.6 Production Summary

*Note: beginning in 2015 regional customer population reporting is standardized. The method is to use the census year (2011, 2016...) as a base, then apply a growth factor to subsequent years and round to the nearest thousand. 2013, 2012, and 2011 will be corrected to follow this method. 2009 will be changed back to the original reported value.
