A method for forming a filter for passing contaminated water using elements that are made wholly or partly of degradable material. The increased area available for flow is obtained by providing a first media for which the increase in area for passing the contaminated water is desired, adding a second media comprising of a plurality of degradable elements, and allowing the elements of to degrade to bring about an increase in the area available for passing the contaminated water.

Method and apparatus for filtering contaminated water
A method for forming a filter for passing contaminated water using a device and one or more media. The device comprises of one or more elements that are capable of undergoing degradation. The increased area available for flow is obtained by adding a first media to predetermined areas of the device and allowing the elements to undergo degradation to bring about an increase in the area available for passing the contaminated water.

A method for forming a filter for passing contaminated water using a device and two or more media. The device comprises of one or more elements that are capable of undergoing degradation. The increased area available for flow is obtained by adding a first media to first predetermined areas of the device, adding a second media to second predetermined areas of the device, and allowing the elements to undergo degradation to bring about an increase in the area available for passing the contaminated water.
A device and method for increasing the area available for passing contaminated stormwater through a granular media. The device comprises of one or more elements of predetermined size and shape. The increased area available for flow is obtained by introducing a first media into predetermined areas of the device, introducing a second media into predetermined areas of the device, and bringing into contact the first and second media.

A device and method for increasing the area available for passing contaminated stormwater through a granular media. The device comprises of one or more hollow elements that are made of degradable material and are of predetermined size and shape. The increased area available for flow is obtained by introducing a first media into predetermined areas of the device, introducing a second media into predetermined areas that are adjacent to areas containing the first media, and allowing the elements to degrade to bring about contact between the first and second media.
