Welcome To Thompson Flow Investigations

 Thompson Flow Investigations Inc. (TQI) is a firm specializing in various types of hydrotechnical work such as flow monitoring, inflow/ infiltration (I/I) investigations and modelling. Modelling services include storm water management, sanitary sewer, highway and rail yard drainage plus deterministic modelling of I/I. TQI was formed in February, 1998 by its two principals; Larry Thompson M.A.Sc., P.Eng. and Karen Dennison M.Eng., P.Eng., each of whom have over 30 years experience in water resources and flow monitoring.

 Prior to starting TQI Inc., Mr. Thompson built and managed a dedicated I/I group at CH2M Gore & Storrie Ltd. During this time he constructed roughly 600 monitoring stations across the country and carried out numerous I/I investigative studies. Karen Dennison was Manager of Water Resources at UMA Engineering Limited and continues to do drainage projects for consultants as well as flow monitoring work.
