With regard to the filtration claims I don't think the filter is the paving as much as it is the gravel in the water feature. I think that emulating nature is the best way to filter pollutants, but my cocern is whether the chemicals can be filtered effectively and quickly enough for irrigation purposes. I suppose I may have to build one to find out.
