The City of Selkirk gets its water from four carbonate aquifer wells in the City and two in the R.M. of St. Andrews. Water is then cleaned at the Selkirk Water Treatment Plant before being sent out to distribution lines. Five of the six wells are deep, while the Tower well is shallower. Because of this water from the Tower well needs more maintenance. McLean Well (drilled in 1959), Christie Well 1 (drilled in 1968. used only in emergencies), Rosser Well (drilled in 1987), Tower Well (1997), Christie Well 2 (drilled in 2015), Render Well North (drilled in 2017), Render Well South (drilled in 2017).
