ArcGIS Spatial Analyst Helps Model Water Availability During the August 14th Blackout Track: Water, Wastewater, and Stormwater Author(s): Brian Wopershall, Chris Davis The Cleveland (Ohio) Division of Water has four main pump stations that deliver treated Lake Erie water to approximately 1.5 million customers. At 4:11 pm on August 14, 2003, these pumps were knocked out by the blackout that hit most of the Northeast United States. Using ArcInfo 8.3 and the Spatial Analyst extension, elevation data and hydraulic grade information taken at Cleveland Water facilities were utilized to produce hour-by-hour raster plots of water pressure and estimates of the number of customers without water from the time of the blackout until service was restored. With these plots, the impact of the outage could be realized on a detailed level, both spatially and temporally.
