Re: Summary Report – Safe Drinking Water Act – Millbrook DWS
Dear Mr Hancock:
Attached is the 2012 Summary Report for the Millbrook DWS. This report is completed
based on the information we have in our records in accordance with Schedule 22 of O.
Reg. 170/03, under the Safe Drinking Water Act, which requires a Summary Report to
be prepared not later than March 31st of each year for the preceding calendar year.
After your review and inclusion of any additional information, this Summary Report is to
be provided to the members of the municipal council. Please ensure this distribution.
Section 12 of O. Reg. 170/03, requires both the Summary Report and the Annual Report
be made available for inspection by any member of the public during normal business
hours, without charge. The reports should be made available for inspection at the office
of the municipality, or at a location that is reasonably convenient to the users of the
water system.
Sincerely,

What else must the Report contain?
The report must also include the following information for the purpose of enabling the owner of
the system to assess the capability of the system to meet existing and planned uses of the
system:
1. A summary of the quantities and flow rates of the water supplied during the period covered
by the report, including monthly average and maximum daily flows and daily instantaneous
peak flow rates.
2. A comparison of the summary referred to in paragraph 1 to the rated capacity and flow
rates approved in the system’s approval.
Attached please find a copy of the Annual Records of Water Taking for the Millbrook DWS which
contains all required flow information.
In November 2012, the standpipe and wells 1, 2 and 3 were cleaned and inspected. This
required higher flows and volumes of water; however, all water takings were within the permitted
amount.
2
The Ontario Clean Water Agency aims to strictly adhere to operational and compliance limits,
however certain operational circumstances may cause results to be temporarily outside of the
limits. Limits that are momentarily surpassed as a result of pump start-ups, power
outages/generator tests, pump rotation, calibrations, alarm verification, etc are a normal part of
operations and do not indicate a true exceedance. A true exceedance will be noted and
documented within the report.
When Does the Report Get Submitted?
If a report is prepared for a system that supplies water to a municipality under the terms of a
contract, the owner of the system shall give a copy of the report to the municipality by March 31.
