Well I posted a few pictures of this in the random picture thread. So here is the deal. A thrift store that has a side driveway dock area where the truck pulls along side the building and loads/unloads from a side door. So this drive way takes a dip in the middle so the door will line up with the building with ease.
Most of these have a normal storm sewer basin that flows to the triple separators. This one used a trough drain that fed an outside pump which pumped to an overhead line. They had some issues with the outside pit (detracted) and it was clogging the pump. So someone had the bright idea of installing an inside pump pit, and run a pipe from the old pit to the new pit. But they left the condition of the old pit as it was. So over the next two years they had issues of mud washing in from under the driveway into the new pit clogging the pump. So I mad the necessary connections and repair.
