Intake screens such as these can be purchased. However, they are easy enough to make to
suit your site. You can use a stainless steel mesh and a plywood box, make sure you
support the screen from behind with stainless steel rods/frame otherwise during floods the
mesh will be pushed in. A fine, smooth stainless steel gauze with a hole size typically 1-3mm
should then be placed over the stronger frame. This smooth gauze will allow debris to slide
off easily and prevent small aquatic life forms from entering the pipe line.
