Well Installation & Completion in Mulmur Township

Well installation on the elevated Niagara Escarpment plateau in Mulmur Township centres on achieving a reliable casing-in-rock seal in the shallow limestone bedrock and setting the pump at adequate depth to account for the deeper water tables found at higher elevations. The thin overburden typical of Mulmur means that the casing is seated into bedrock within the first few metres, and the grouting must bond the steel casing securely to the surrounding rock to prevent any surface water from tracking down into the aquifer. The cement grout must fill every void between the casing and the sometimes-irregular rock surface, and we verify completeness by monitoring grout volume against the calculated annular space. Below the cased section, the borehole continues through limestone and dolostone as an open hole, with the productive fractures that supply water occurring at various depths. The deeper water table associated with Mulmur elevated position means the pump must be set further down in the well than would be necessary at lower elevations, requiring longer drop pipe and heavier-gauge wiring. The pitless adapter installation can be complicated by the shallow rock, and we use specialized approaches to ensure a frost-protected connection regardless of how close the bedrock is to the surface. The rural, somewhat remote character of Mulmur means that every well installation must be done right the first time — these properties depend entirely on their wells, and service response times are longer than in more populated areas. We ensure every Mulmur installation is built to a standard that minimizes the likelihood of future problems.
