• The City of Toronto requires professional engineering services to conduct a study that will define causes, assess potential impacts, and provide direction on mitigation measures regarding hydraulic transients in the water distribution and transmission systems for pressure districts 1E, 2E, 3, 3E, 4, 4S and 5S (the Study Area.) • To merge and validate a hydraulic water model for pressure districts 1, 1E, 1W, 2, 2E, 3, 3E, 4, 4S and 5S that will be used for creating a transient model for the study area for assessing adequacy of existing surge protection devices and current operating strategies of facilities and the transmission and distribution water systems. • To develop a monitoring plan for collecting data in the field including continuous pressure logging, C-factor testing, fire flow testing, and flow monitoring to be used to validate the aforementioned hydraulic model; to calibrate and validate a new water transient model for the study area; and finally, to implement the monitoring plan in the field. • To create, calibrate and validate a water transient model for the study area to assess impact and risk of transients in the water transmission and distribution systems, provide surge protection for future system conditions to accommodate future population growth and expansion of the water system, and recommend schedule and cost for capital implementation of recommended protection measures. • To prepare a city-wide plan for the installation of temporary and permanent sensors in facilities and the distribution and transmission watermains to be implemented by the City after completion of the study. Make a recommendation for number of sensors, location, cost and implementation stages. Purchase and installation of sensors will be done by the City and will not be part of this study.
