RECOMMENDATION: THAT the 2017 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 2017 reporting period, the Kitchener Distribution System met the
requirements of the Safe Drinking Water Act.
BACKGROUND:
As outlined 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:
that 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.
*** This information is available in accessible formats upon request. ***

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, 2017:
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.
A portion of Kitchener (River Ridge area) is supplied by the City of Waterloo.
Kitchener supplies water to a small section of Waterloo (Ira Needles area) and
water travels through the Kitchener distribution system to Breslau. The City of
A Ministry of Environment and Climate Change (MOECC) inspection was
completed February 1-2, 2018 and covered January 1, 2017 to January 31,
2018.issued their
report; preliminary findings did not identify any issues of non-compliance while
the inspector reviewed documentation with the City on February 1-2.
There were 2,638 chlorine residual samples taken and 2,053 bacteriological
samples taken within the distribution system. Of these, there were 35 Adverse
Table 1).
o The number of low chlorine AWQIs (22) were at repeat locations and were
largely due to broken valves, large diameter watermains taken out of
service for construction, and other construction activities which created
temporary dead ends. These dead ends have now been resolved.
o The majority of the total coliform AWQIs (8 total) were on temporary
watermains and the resamples were clear.
Dead end watermain flushing 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
cause the potential for bacteriological growth. 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
are more reflective of what is on the sampling tap, rather than what is in the
2 - 2
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 types of strains of coliform bacteria. Most are
-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, aresample using a different technique, which
provides a number of total coliforms to analyze in consultation with Public Health
and the MOECC. Based on a risk assessment of a number of factors including:
the coliform count, chlorine residuals, upstream/downstream coliform counts, the
requirement for a boil water advisory is determined.
There were two precautionary self-imposed (2) Boil Water Advisories in 2017.
One was due to a contractor hitting a private water service during private side
sewer lateral work and potentially contaminating it with sewage. The second was
due to construction and dead ends in the area. The sample results showed no
contamination.
Lead testing sampling programs were completed in February/March and
September/ October 2017.There were 2 locations with lead exceedances in the
plumbing system and 2 hydrants in the distribution system (4 related AWQIs).
The hydrant with repeated high values was replaced and the follow-up sample
was free of lead. 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.
