I basically have the filter portion set up like you link mentions. The problem I have is that I have another pond before it that acts as a sedimentation chamber. Both have the same invert elevations. Here is my attempt at attaching a picture to explain better. If you have a better way to...
I am modeling a site and breaking it up into drainage area per BMP. I have a drainage area a little over an acre and am trying to model a sand filter treating this runoff. I have the sand filter modeled as 2 ponds. The first pond is the sedimentation chamber to allow settlement of large...
Thanks atook. I wanted to use large rotors but am worried about bad wind drift since it is in somewhat of a residential area. Also, our areas of application are small and square/rectangular and I figured smaller radius would allow more efficient coverage. I also figured on just a basic precip...
Thanks. We are in the coastal region with good sandy soil that will take quite a bit of infil. We have done these systems before with drip irrigation and all still work good. I think we can apply a lot of water but I want it at a relatively low rate so we don't have runoff. I am now thinking...
We have a small MBR WWTP and instead of drip irrigation I was told to do spray irrigation over a grassed area. I don't have any experience in the design of spray irrigation. Rain Bird was not helpful. I found specs on some of their pop-up heads and found something I thought was reasonable...
Thanks a lot ya'll. I just got a call from somebody else in the town and they said they recorded a flow of about 850 gpm. Still not all the info I need but I am thinking KWDWaterEngineer is on target. I am going to wait to get more clarification before I go any farther with this.
I am doing a small waterline extension to serve a development in a rural town. The town code requires fire flows of 1000 gpm. The two nearest hydrants were tested and gave 650 gpm and 750 gpm. Do towns usually let you bend the rules since their system does not provide required flow? If not...
I am a civil eit so i figured I'd ask in a structural forum. We have an anchor rod running through a concrete deadman. We were not sure what the final angle would be so we spec'd a 2" pvc sleeve to allow for some variance. Didn't think about what size washer plate we needed. Now I am trying...
Anybody had any experience using the ADS/Hancor stormwater products? How did they work out for you? Have any issues getting them permitted? In the permitting process right now and wondering how bad its gonna be.
Hey,
Thanks for your input. I would really appreciate it if you could send me an epanet file of something similar to what I am dealing with. I know how to do it if there was only one connection to a source or if there was 2 connections to 2 separate sources, but struggle with 2 connections to...
I am designing utilities for small subdivision and have been given hydrant flow data near the site. I tried using this with EPANET and straight line piping (conservative, assuming no network) but could not maintain fire flow. Now I have to be more specific and take the network into...
