thanks! since we no longer have the program in our office, i re-modeled the pond using tr20.

I'm looking at an old stormwater report for a site. The pond was apparently modeled using POND-2 Version: 5.20 S/N (so it says on the top of the calc results). Does this program sound familiar to anyone? This isn't TR55 is it?

Thanks francesca. One more ? for ya. Other than being able to calc. stage storage within a pipe, what else does the program do? I'm assuming you could use it to route/model a pond and if that's the case, i'm not sure if that program would be recognized/approved around here in IL - most...

thanks for the response. I have Hydrafow Storm Sewers 2005, do you know if this program has hydrographs for calculating stage storage? I couldn't find "hydrographs" under any of the functions.

I'm working on a project where we will be providing storm water detention within a proposed storm sewer. Does anyone have any idea on how to calculate stage storage within a storm sewer pipe? The storm sewer will have different diameter pipe. Do you have to run a separate stage storage tabel...

I did mean a concrete manhole for the valve vault. We're proposing a cut-in connection since as you mentioned, it will be for a proposed 12" connection to an exsting 12" line (municipality doesn't allow same size pressure connections as cvg mentioned). Thanks for all the help.

anyone ever spec. out a typical walking trail constructed using fine aggregate? I'm proposing a 6" thick section using fine aggregate (FA-6).

generally, what's the difference between a cut-in and pressure connetion. is a valve vault typically required for a cut-in connection (VV is typically required for a PC). also, how do you typically call out a cut-in (simply "proposed cut-in connection")?

ads makes downspout adapters:

actually, it was cited verbatim from Illinois Recommended Standards For Sewage Works thanks for your input/insight lha

sheesh...found out it wasn't a force main (which would of helped my search) so the new Q would be: when connecting a smaller diameter gravity sewer to a larger diameter gravity sewer...what should be the change in invert elevation i think the A is: When a smaller sewer joins a larger one, the...

when connecting a gravity (sanitary) sewer to an existing sanitary sewer manhole force main, can you connect at the existing elevation or is there a required elevation (i.e. 6" above existing invert) you need to follow?

We designed a concrete lined weir for the above-referenced project. The client was wondering if we could do anything to the concrete surface to discourage skateboarders from using the weir (and ultimately falling into the pond). The weirs are relatively large (could be ideal for kids and...

thanks blt!

anyone know where (i.e. website) i could find a typical standpipe detail?
