My local park underwent a major overhaul in the early sixties. I recall watching the work as a very young lad. Along with new concrete pathways to replace the old asphalt network, and a refurbished bridge over a newly updated waterway, an underground water system was installed. This allowed for hoses and sprinklers to be used to water grass and flowers in any corner of the park.
The Buckner system involved subterranean piping throughout the park. Located at various places were ground level coupling points. Simply insert a handy Buckner valve, turn, and presto running water. Nothing could be easier.
I assume that when the system was installed there was a map clearly indicating where the coupling points were located. By the time I worked for the city as a student in the late seventies said map was long gone. They say information is power. Well there was a sense of that felt by those who knew where the coupling points were. From foreman to employee this lore was passed down over the years. As the photo above shows, the system has been improved over the years and includes large green covers for the coupling points. That’s just plain cheating!
Knowing where a coupling point was located could cut down on time wasted walking about in concentric circles kicking at the grass in an effort to find it. Although many coupling points were found serendipitously by running over them with a lawnmower. Aside from leaving one’s nerves jangling after such a discovery, the blade of the lawnmower was less than ideal!
