WEF Discussion Forums
I read an article in WEF several years ago about a municipality that utilized a pretty intuitive idea regarding identifying sources for I&I. They had placed numbered ping pong balls into the storm sewer. They removed the numbered ping pong balls from the bar screen and where able to identify where it had came from (as a source of I&I ). Does anyone know where I can find that article?
One of our municipal customers is questioning our wastewater flow metering by showing lack of correlation with municipal water usage. The community has high water tables and, up to 5 years ago, no connection inspection program. In the past, I have not seen good correlation between municipal water usage and wastewater flows, even with tight collection systems. Does anyone know of studies or have experience in correlating these two data sources?
