A bored, drilled, or driven shaft or a dug hole whose depth is greater than its largest surface dimension, which is completed above the water table so that its bottom and sides are typically dry except when receiving fluids.
Small excavated trenches filled with stone to control and infiltrate rooftop runoff. EPA: Environmental Protection Agency. Erosion: The process of soil detachment and movement by the forces of water.
A type of BMP comprised of a small, excavated pit, backfilled with aggregate, which is used to infiltrate high quality runoff.
a gravel-lined hole that accepts water discharged from the pipes and eventually percolates into the soil
a hole bored into the underlying lava until a large crevice area or caverns are found
a hole dug into the ground to below the depth required to receive the draining tile and then filled below the tile with gravel
an exploratory well found to be incapable of producing either oil or gas in sufficient quantities to justify completion as an oil or gas well
a pit or barrel filled with stone or gravel that allows the water to drain well away from the foundation
a simple and clever system used for draining excess water out of a low spot or from a water-laden area such as at the foot of a downspout
a surprisingly inexpensive system that consists of a buried drainpipe that runs from a small catch basin (where the water ponds) to a collection container (a plastic trash can in our example) somewhere away from the house
drain hole, filled with rocks
(1) A well that does not supply water because the well has been drilled into an aquitard or into rock that lies above the water table; (2) a well that does not yield oil, even though it has been drilled into an anticipated reservoir.
A gravel-filled hole used to receive and drain water runoff; part of a drainage system to which water runoff is directed via a perforated drainpipe.
A deep hole, covered and designed to hold drainage water until it seeps into the ground.
A well used for the discharged water in an open-loop geothermal heat pump.
A dry well is an underground structure that disposes of unwanted water, most commonly stormwater runoff, by dissipating it into the ground, where it merges with the local groundwater.
