    How to find pipe depths on inlets with a Snout

    Hey All, I have a job where utility lines need to cross a storm sewer line. The Township upgraded all the inlets in the area to include Water Quality Snouts and did not get as-built elevations on the pipes prior to placing the snouts. The inlets are now filled with water and the snouts do not...

    Hey all. I have 25 Ac. site with a pond at the bottom. The site is located within a rate restriction zone where the post development flow rates have to be 50% or less than the predevelopment rates. The pond is too small to provide any meaningful stormwater management so I need a stormwater...

    Using weighted Curve Numbers for Basin Routing

    Okay guys.... I just got off the Phone with a guy that is the Township Engineers Stormwater reviewer and all stormwater comments in the Engineers review are generated by this reviewer. He just told me that I'm not allowed to use weighted curve numbers for a Basin Routing using TR-55. I'm told...

    Simple Channel Design Software

    Hey All, I'm wondering what everyone uses for channel design these days. I have an Old Old Old Haestads DOS Program that have been using (don't laugh... it works) and now I have to get a new 64 bit computer that will run Civil 3D properly and sadly, I have to see my old FLOW MASTER program go...

    Hey Guys, I have an interesting problem in that a High School wants to replace the existing turf field with artificial turf and the question is ... Will the existing stormwater basin be able to handle the runoff without modifications? (I Know...Cost is no object when its tax payer money) The...

    Hydraflow Seepage Bed Design

    Hey all, I'm a complete newb to Civil 3D and Hydraflow and I'm trying to design seepage bed and route a storm though it. I put the exfiltration percolation rate in for the contour area only and it gives me a warning that I should be using the wetted perimeter. However, PADEP only allows for...
