SUBJECT:

Inspection of the Town of Markham Drinking Water System by the Ministry of the Environment, December 2004

 

 

 


 

RECOMMENDATION:

THAT the report dated May 2, 2005, entitled “Inspection of the Town of Markham Drinking Water System by the Ministry of the Environment, December 2004” be received;

 

AND THAT Council directs staff to report back on an inter-departmental strategy to implement the MOE recommendation for improving system “Best Management Practices” by enacting a by-law to prohibit cross connections between the municipal water supply system and non-potable water sources;

 

AND FURTHER THAT Council directs staff to report back on an inter-departmental strategy to implement the MOE recommendation for a written agreement with the Municipality of York for the supply of water and ownership of the water distribution system.

 

 

PURPOSE

The Ministry of the Environment (MOE) inspected the Town of Markham water distribution system on December 14, 2004 for compliance with the Regulations made under the Safe Drinking Water Act.  This report informs Council of the actions required for regulatory compliance and improving system best management practices, along with the actions recommended by the MOE for ensuring a long-term and reliable supply of water is provided.

 

 

BACKGROUND

The MOE Inspection Report for the Markham Water Distribution System provides the Inspector’s assessment of compliance with the Ministry’s policies and regulations. The Inspection Report is provided as Attachment ‘A’ to this report.  The Inspection Report provides observations made by the MOE inspectors and any associated actions required for compliance or improving best management practices.  The Inspectors made three observations in their System Inspection Report dated January 31. 2005.

 

Markham Waterworks was required to respond in writing to the MOE regarding the actions the Town plans to take in respect to the “Actions Required” and “Recommended Actions” by February 21, 2005.  The written response is provided as Attachment ‘B’.

 

 

COMPLIANCE WITH REGULATION 170/03

The MOE report identifies that the Town of Markham on one occasion did not comply with Schedule 13-6 of Ontario Regulation 170/03, made under the Safe Drinking Water Act.  Schedule 13-6 requires that at least one water sample must be taken in the distribution system and tested for trihalomethanes every three months.

 

The Town did not comply with the specified timeline for submission of the required samples for trihalomethanes in the first quarter of 2004.  Due to a work order scheduling error, the samples were submitted April 7, 2004, which was seven days after the end of the first quarter of 2004.  While these samples were technically submitted late, Waterworks submitted the required samples as soon as staff recognized the oversight.  Waterworks has subsequently implemented a revised sampling schedule to ensure that all samples and testing required under Ontario Regulation 170/03 are undertaken at the required intervals.  All samples required after April 2004 have been submitted on time.

 

The MOE inspector noted in the Inspection Report that the results for all trihalomethane samples collected from March 2002 until the date of this inspection had met the Ontario Drinking Water Standards.  The quarterly submission of samples is intended to ensure that levels of trihalomethanes are routinely monitored in the system.  The late submission of quarterly samples did not compromise the water quality in the system or the ability of Waterworks to monitor this parameter.

 

 

BEST MANAGEMENT PRACTICE ISSUES

The MOE identifies that Markham should implement a by-law to prohibit cross connections between the municipal potable water system and any sources of non-potable water.

 

At present the Town of Markham relies on Section 7.6.2.1 of the Ontario Building Code, which prohibits cross connections between potable and non-potable water systems.  The Building Code is enforced by the Building Standards Department. The Building Code, however, does not require isolation of all private plumbing and water systems from the municipal system by means of a back-flow prevention device or check-valve system.  This presents a risk to the municipal potable water system from inadvertent back siphonage (backflow) of non-potable water, and even and deliberate introduction of deleterious matter into the municipal system.

 

A coordinated strategy between Waterworks, Engineering, Building Standards, By-Law, and the Legal Departments is required to implement a program to eliminate and prohibit cross-connections.  It is recommended that a working group from these Departments be formed to develop policies and procedures to control cross-connections and prevent back siphonage within the Town.  A copy of the MOE Inspection Report will be forwarded to the appropriate Directors in the Engineering, Building Standards, By-Law and the Legal Departments for review so that they are aware of the MOE requirements.

 

ADDITIONAL RECOMMENDED ACTIONS

The MOE recommends that the Town of Markham develop a written agreement with the Regional Municipality of York for the supply of water.  The agreement should state clearly which operating authority has responsibility for transmission pipes and other equipment associated with the water supply system.  The agreement should also be specific in indicating where the Town of Markham’s distribution system begins and ends.  The agreement should include the maximum flow rates allowed for the Town and projected flow rates over the next five years.

 

Markham Waterworks has informed the MOE that a water supply in the Region of York is addressed through the Municipal Act 2001 Sections 11, 19, 20 and 89.  Specifically, Section 11(2) of the Act provides York Region with “exclusive jurisdiction” over water production, treatment and storage, and “non-exclusive jurisdiction” over water distribution in the Region.  This means that only the Region has authority to produce and treat water.  The lower tier municipalities do not have the authority to produce water.  Further, Section 89 of the Act requires that the lower tier municipality in York Region “shall not, without the consent of the regional municipality, purchase water from any municipality except the regional municipality”.  Together these two sections of the Act legislate that the Town must obtain water from the Region and forms the agreement for supply of water from the Region.

 

Staff from the Town and Region has already met once to discuss a policy and agreement that would clearly define the ownership and responsibility for transmission pipes and other equipment associated with the water supply system.  In addition, the Region has completed the Long Term Water Project Master Plan Update.  The Master Plan identifies the recommended infrastructure program to meet the water usage requirements up to year 2006, including projected maximum flow rates.

 

A coordinated strategy between Waterworks, Asset Management, Engineering, Development Approvals and York Region staff is required to develop the written agreement requested by the MOE.  It is recommended that a working group from these Departments be formed to meet with the Region to initiate this process.  A copy of the MOE report will be forwarded to the appropriate Directors in the Engineering, Development Approvals and Legal Departments for review so that they are aware of the MOE recommendations.

 

 

FINANCIAL IMPLICATIONS

At present, the only financial implication of the recommendations set out in the report is the requirement for staff time and resources.  Preparation of staff reports necessary to inform Council of progress made towards implementing the MOE recommendations represents an unplanned for priority.

 

Additional staff resources may be required to implement and enforce a bylaw to control cross-connection and prevent back-flow siphonage.

 

Staff is not aware of any financial implications resulting from the one reported incident of non-compliance with Schedule 16-3 of Ontario Regulation 170/03.  It is possible that the Enforcement Branch of the MOE may impose financial penalties for non-compliance at a later date.
