The Enterprise engineering section wasn't a water plant but a beer brewery in San Fernando. The 2009 Enterprise was bumped up from the 300 meters of the classic one to 725m in order to fit it, the enourmous shuttle hanger and the deck behind the bridge inside.
The brewery didn't bother me one iota. Nor did the shipyard location. I'd pick a gravel driveway and a real location over a shiny, Star Wars-style blue screen/CG set.
