Would anyone happen to know a good source for statistics on the residential irrigation industry? I am looking for the information below to put in an industry report: (1) the market share of Rain Bird, Toro, and Hunter (should any other major players be included?), (2) their total number of existing systems (approximate), (3) their annual installs (approximate), (4) the average cost of a typical residential sprinkler system installation. Any leads, info, insight is greatly appreciated. It has been difficult to find info on this industry. Thanks in advance.
