Hi everybody, I work for and Engineering Company in Chicago
For the last two week I have been trying to find a way to incorporate the first flush concept in one of city of Chicago projects (parking lot) but I couldn’t find any first flush system that can be installed in manhole or catch basin so it could send the first flush to the sanitary sewer and after that draining the rest of the rain water to the storm sewer.
If anybody has any information about any sort of solution for this issue please I will be really appreciated if you can share me with your information
Thanks,
Anas Alkhatib
