After this debris is dried, we haul it to a recycler. A sump collects all the debris which is carried by runoff. These sumps require our VacCon machine to remove this debris. This design allows debris to settle in the sump, the oil-water elbow keeps oils and floatable debris below the elbow, allowing only the cleaner runoff into the drywell. Your private drainage can take various routes before it reaches the public system.
Most properties drain to the curb.
The City is responsible for runoff from City streets. Private drainage responsibilities include keeping runoff from crossing neighbor's property, and directing the runoff to an approved discharge point. The City does have some mapping of private drainage systems. For the most part, these systems don't show on City drainage maps.
