Walker Partners was engaged by the City of McGregor to create a hydraulic model of the City’s existing potable water distribution system to identify any distribution, pressure, and/or water supply deficiencies and recommend reasonable cost effective options for correcting any deficiencies identified. A computer model of the City’s distribution system was created in EPANET software.  The model was compiled utilizing information provided by City of McGregor staff in the form of plans, maps, and personal knowledge of the system. Walker Partner staff performed inspections of water plant sites to obtain piping layouts, operating manuals, pump station manufacturer’s information, and well pump manufacturer’s information.  Walker Partner staff also installed digital pressure recorders and performed flow tests at select locations to develop the information required to calibrate the model.

The model includes all distribution lines, elevated / ground / underground storage tanks, and pumps within the system. Walker Partners analyzed computer simulations of the existing system and water plants under various conditions in order to prioritize needed infrastructure improvements while maximizing system efficiency and providing for future growth.
