New Wins: The City of Whitehorse, YT (City) retained GeoAdvice to develop and calibrate their water distribution and sanitary sewer models. Calculation and allocation of existing and future system demands and loads were conducted. GeoAdvice built the water and sewer models using the City’s GIS data, maintaining a one-to-one match of model pipes to GIS pipes. The water model was then calibrated using hydrant test results. Identifying system deficiencies and providing recommended upgrades are currently being completed. A uni-directional flushing program, water quality model, temperature model, and water and sewer operational manual will also be developed.
