More information on wetlands

Hi everyone,

I have recently come across a local (UK) company www.biologicdesign.co.uk whose aim is 'creating multi-species constructed wetlands for sustainable wastewater purification, biodiversity enhancement and resource production'. (Theirs is not a gravel reedbed system). Although obviously based within the UK environment, I thought perhaps some of the principles described on the website might be of interest to the 'wastewater treatment' or 'wetland/pond' people in the village. I know that this company uses bentonite successfully to line ponds in situations where the water would otherwise drain away, and including situations when the pond is dry for some of the time.
