Contesto Today we're going up to the spring...we dig out the spring box, which is filled with gravel to filter the water.

Questa la definizione dal link:a spring box is a watertight collection box constructed of concrete, clay, or brick with one permeable side. The idea behind the spring box is to isolate spring water from surface contaminants such as rainwater or surface runoff. All spring boxes should be designed with a heavy, removable cover in order to prevent contamination from rainwater while providing access for disinfection and maintenance.
