A system and method for determining the pervious and impervious area within parcels associated with a municipality for purposes of generating bills for storm water runoff to parcel owners. Aerial imagery, collected from an aircraft and/or satellite, of the relevant municipality, or portion thereof, is collected, processed, and analyzed to determine the amount of water impervious area associated with each relevant parcel within the municipality. This information for each parcel may then be used to determine an appropriate amount of money to be charged to the owner of each respective parcel. The amount of impervious area per parcel is calculated based on parcel boundary information specific to the municipality that may contain spatial domain errors.

The invention provides a novel vegetation shallow trench and a method for processing runoff rainwater by using the novel vegetation shallow trench. The novel vegetation shallow trench comprises a vegetation layer and a shallow trench, wherein the shallow trench comprises a shallow trench bottom (1) and a slope (2), and an infiltration/drainage pipe (3) is buried in the shallow trench bottom (1). When surface runoff rainwater (9) enters the shallow trench and flows along the slope, the runoff can be purified through retention, filtering of vegetation (7), absorption and permeation, a part of runoff rainwater accumulated at the shallow trench bottom (1) enters a filter material layer surrounding the infiltration/drainage pipe (3) through infiltration effect, and the filtered runoff rainwater is drained into a receiving water body or other processing facilities through the infiltration/drainage pipe (3). Since the infiltration/drainage pipe (3) is designed at the shallow trench bottom, the novel vegetation shallow trench is remarkably improved in transmission, filtering and infiltration capabilities, has the advantages of small floor space, compact structure and strong contaminant blockage capability, and thus is applicable to a rainwater runoff pollution control system for high-density areas of a city.

A separation tank having an inlet and an outlet and forming a low flow path and a high flow path, both conveying water from the inlet to the outlet. At normal, low flows, the water enters the inlet and passes through the low flow path having treatment chambers to remove, respectively, heavy materials and floatable materials. At high flows such as with heavy storm runoff, water exceeding a predetermined flow rate is conveyed from the low flow path into the high flow path where there are baffles to treat the water to remove both heavy materials and floatable materials. In optional embodiments, there is a filter/recharge chamber that may contain a filter and/or a groundwater conveyance system such that filtered or unfiltered water can be discharged from the low flow path through a groundwater conveyance system to groundwater, to the normal outlet, or both.
