River wells
The drawing above is representative of the type of illustration the Field Guide will use. Since the book will be available in ebook and paperback format, this type of illustration is more readable in ebooks, especially the black and white versions. The drawing depicts a river well, one form of a structure to take water from a stream or river, or pond for that matter. Surface water sources often have algae and seasonal high turbidity and sediments. By digging a shallow well a few feet away from the water edge, filling it with gravel and then placing a perforated vessel in the middle of the gravel, most of the algae and sediments problems are solved. The gravel layer extends above the water level so that the well does not become a breeding ground for mosquitoes A pump can then be placed in the perforated vessel and operated without concern for the pump being plugged. This is an example of the kind of information available in the Field Guide. The book is scheduled for publication May 2014. Please click on the link above or in the side bar, to follow this project. Thanks!
