Pumping test planned for Cannington

As part of an environmental assessment addendum for additional water supply, Cannington residents can expect a pumping test later this month.

Residents with private wells are being asked to allow International Water Supply Inc. to install level-loggers in their wells to monitor the well level prior to, during, and after the pumping test.

“Participation in the private well monitoring is voluntary; however, establishing the baseline condition of your private well will facilitate resolution of any claims that the Test Well drilling and/or Pumping Test has impacted your well,” reads a release from the Township of Brock.

The release notes that in 2011, Durham Region completed a Class Environmental Assessment (EA) Study for additional water supply capacity for the Community of Cannington.

“The preferred alternative was to construct a new municipal well at a site located at 1735 Regional Road 12. One test well was installed and tested at the proposed site in 2009,” reads the release.

“The Region is currently undertaking an Addendum to the Class EA for an additional test well on the same site to confirm additional yield of water supply. The Region has retained International Water Supply Ltd. to drill the new well and conduct a pumping test.”

According to the Township, the new test well will be step-tested for 24 hours, then both test wells will be pumped for 48 hours. The expected combined pumping rate will be approximately 9 litres/second.

The Region is expected to suspend the Test Well drilling and/or Pumping Test if they are found to be causing detrimental impacts on the local private wells.

“Once the additional water supply yield is confirmed in the two test wells, and no detrimental impacts to the local private wells are found, the Region will finalize the Class EA Addendum. The report will be posted on Durham Region’s Website at www.durham/ca/cdeap,” reads the Township notice.
