WebThe easiest and fastest way to find out where stormwater pipes are located is by opening nearby manhole lids. These could be either a stormwater or sewer access point. Once the lid is open, you can physically measure the size of the pipe and the invert level. These measurements become known as the Quality A location. WebTypically, designers size ponds to equal the water quality volume (i.e., the volume of water treated for pollutant removal). They may consider using a larger volume to meet specific watershed objectives, such as phosphorus removal in a lake system.
