The Scattergraph Principles and Practice Poster was presented as a poster presentation at WEFTEC 2005 in Washington, D.C. on November 2, 2005. Both Patrick Stevens and Kevin Enfinger were on-hand to present the poster.
This poster presents 32 examples obtained from 25 cities in 15 states from sewers ranging from 10 to 120 inches in diameter. The poster contains 95,503 data points collected during 905 monitoring days from 1993 to 2005. The flow monitoring data are supported by 80 confirmations. The data displayed on the poster represent nearly 6.3 billion gallons of measured flow - enough to fill a 96-in diameter sewer from San Francisco to Miami!
