10617 - Request for proposal for well rehabilitation and pump upgrades

The RM of Springfield is dependent on groundwater for its potable water supply needs. The main source for water supply for the RM’s Oakbank water system is groundwater obtained from two groundwater wells located on Heatherdale Road near the Hazelridge Road intersection. The North well was completed in Oct 1996 and South Well was completed in Sept 1994. The South well was redeveloped in 2014 and pump was replaced. The north well currently pumps @ 26.5 l/s and south well pumps@ 30l/s. The department intends to conduct pumping test on the wells to determine maximum safe yield and install higher capacity pumps to have higher discharge.
 
It is proposed to re-develop South well and conduct 72 hour pumping test @ 35 l/s to confirm the safe discharge. If on completion of the test it is concluded that the well is capable of delivering 35 l/sec without any adverse effect on water quality a new pump capable of pumping @35l/s will be installed in the South well and a similar pumping test and pump replacement will be carried out for North well. However if it is determined that South well is not capable of delivering 35l/s a test will be conducted to determine if it can deliver 30l/s and  new pump capable of delivering 30l/s will be installed and no testing or pump replacement  will be carried out on North well. The Work will be carried out in accordance with best practices and applicable regulations and guidelines.
