Not sure which forum to put this in, it could go in several.
I have been receiving this catalog for a while and thought it may come in handy for someone.
www.agridrain.com
Some good parts that i can see being used for "Pondless" Waterfalls, Waterfeatures and good old drainage.
I have not used them because we have a local company that supplies/ fabircates most of these parts.
Thought someone may find this usefull.
