__________________________________________________________________________________________
RECOMMENDATION: THAT the 2018 City of Kitchener Summary Drinking Water Report
be received for information as required by O.Reg. 170/03 Schedule 22 of the Safe Drinking
Water Act,
AND FURTHER THAT the City of Kitchener provide a copy of the Summary Drinking Water
report to the Township of Woolwich and the City of Waterloo as required by Schedule 22
of O.Reg. 170/03.
EXECUTIVE SUMMARY:
During the 2018reporting period, the Kitchener Distribution System met the requirements of the
Safe Drinking Water Act.
BACKGROUND:
Asoutlined in Schedule 22 of the Drinking Water Systems Regulation (O.Reg.170/03) of the
Safe Drinking Water Act, 2002, a summary report is to be prepared and given to the members
of the municipal council. The following information is required to be included in this report:
the system failed to meet at any time during the period covered by the report and specify the
duration of the failures; and
(b)for each failure referred to in (a), describe the measures that were taken to correct the
failure.
The report must also include:
1.A summary of the quantities and flow rates of the water supplied during the period covered
by the report.
9 - 1
REPORT:
The following matters are reported to Council in accordance with the requirements of the Safe
Drinking Water Act, for the period from January 1 to December 31, 2018:
The Kitchener Distribution System is part of an Integrated Urban System, meaning the
Regional Municipality of Waterloo is responsible for water treatment and the
development and operation of a trunk water network to distribute treated water to
Kitchener, Cambridge, Waterloo, Woolwich and Wilmot. The Region provides annual
summaries for each supply and the information is available on their website with a link
from the Kitchener Utilities website. Reports from the connected systems have been or
will be received.
A portion of Kitchener (River Ridge area) is supplied by the City of Waterloo. Kitchener
supplieswater to a small section of Waterloo (Ira Needles area) and water travels
quality report is available on their website.
TheMinistry of Environment, Conservation and Parks (MECP)completed an annual
inspection on January 31, 2019whichcoveredFebruary 1, 2018 to January 31,2019.
findings did not identify any issues of non-compliancewhenthe inspector reviewed
documentation with the City on January 31.
There were 3,402chlorine residual samples taken and 2,133bacteriological samples
taken within the distribution system. Of these, there were 20 Adverse Water Quality
) reported in this time period (see attached Table 1) and all resamples
were clear.
An AWQI does not necessarily mean that the water is a risk to the customer. It means
that a potential problem has been identified and corrective actions must be taken to
resolve the problem. We work with ministry staff and the local public health unit to
resolve the issue, which generally includes resampling.
Dead end watermainand new developmentflushing is a proactive approach to increase
the levels of chlorine in the distribution system. The water is initially disinfected (primary
disinfection) at the treatment plant and sufficient chlorine is added to protect the water
from microbiological contamination as it travels through the pipes in the distribution
system (secondary disinfection). Low chlorine does not pose a threat to human health;
to have an impact to human health, there must be microbiological contamination and
no, or extremely low, chlorine.
Temporary watermains are particularly sensitive as they are above ground systems
influenced by the water heating up in warmer temperatures. This may increase the
potential for bacteriologicalgrowth. Due to the sensitive nature, all temporary
watermains are sampled on an increased schedule (every 2 weeks at multiple
locations). The additional challenge with temporary watermains is the sample port is
located outside and subject to unsanitary conditions. Although efforts are made with the
design of the ports to prevent contamination, sampling is not completed under ideal
sanitary circumstances. The general nature of reconstruction projects often leads to
9 - 2
alse positives, where the results received are more reflective of what is on the
sampling tap, rather than what is in the water. Every positive result is reportable and
resampling must occur in accordance with regulations. When the resamples are clear, it
is an indication that the issue was with the sampling port, not in the water.
The presence of total coliform on a test does not necessarily mean the water is unsafe
to drink. Coliform bacteria can be found in many different environments. There are
several different strains of coliform bacteria. Most are harmless and do not cause
other disease-causing organisms, and their detection would prompt further investigation
and/or corrective action. It is different than E.coli,which is a bacteria only associated
with human or animal faecal matter.
When total coliform is found, a resample is done using a different technique, which
provides a number of total coliforms to analyze in consultation with Public Health and
the MECP. Based on a risk assessment of a number of factors including the coliform
count, chlorine residuals, and upstream/downstream coliform counts, the requirement
for a boil water advisory is determined.
There was one precautionary self-imposed Boil Water Advisory in 2018 as a result of
damaginga sanitary service during a watermain break repair. The sample results
showed no contamination.
Lead testing sampling programs were completed in February/March and September/
October 2018. There was onelocation with a lead exceedance in the plumbing system
and none within the distribution system. The City is not obligated to complete any
additional corrective actions other than reporting, unless directed by the Medical Officer
of Health for the residential plumbing exceedances.
A summary of the quantities of the water supplied by the Regional Municipality of
Waterloo during the period covered by the report is noted on the attached Table 2.
Flows increased in 2018largely due to the hotter weather compared to 2017,however
water supply demand forecastsindicate that 2018 would be the year that population
demand would outpace water conservation measures.The consumption may fluctuate
around this volume depending on weather until population demand clearly exceeds
conservationmeasures.
