Does anyone have or know of a site where I can obtain (free is possible) a Dry weather flow calculation spreadsheet.(or any sort of freeware /shareware program)
You'll spend more time looking online than it will take you to just create your own spreadsheet. I take it you are measuring between two points A & B (or more).... well, enter your data and average your readings for each location then subtract the downsteam flow(s) from your upstream flow(s) and you get your average dry weather infiltration.... free!
