GLWA retained METCO to update their Water Distribution System Hydraulic Model to integrate with their GIS Geocentric Database and SCADA System. The Project also requires developing the updated model utilizing Ã¢ÂÂInfo waterÃ¢ÂÂ platform. The updated GIS were aligned and calibrated with model database to develop a GIS centric model with the capability to integrate with SCADA, Asset Management System of GLWA. The GIS update and Hydraulic Model development/calibration tasks were successfully completed for the entire Detroit Water Distribution System. The final model consists of approximately 45,00 pipes for a total of 3,600 miles with Five Treatment Plants and Nineteen Booster Stations 31,200. updated model has been delivered to DWSD for their use in developing the Water Master Plan. Also, the model was converted to Ã¢ÂÂEPANETÃ¢ÂÂ platform for use by GLWA in developing their 2015 Water Master Plan. The updating of the GIS database involved the following steps: - Gap Analysis - Data Collection utilizing existing Ã¢ÂÂAs-BuiltÃ¢ÂÂ drawings, section maps, limited field visits as its information source - Data organization Ã¢ÂÂ by adding new layers and/or adding new fields to the existing layers and geo-reference to represent accurate information - The updated GIS was integrated with the new Hydraulic Model for full GIS Centric model. The Project was completed in 2014 and was subsequently used in the demand projections and other related analysis performed for the 2015-DWSD/GLWA Water Master Plan.
