IN LANDSCAPE ARCHITECTURE AND GARDEN DESIGN, A WATER FEATURE IS ONE OR MORE ITEMS FROM A RANGE OF FOUNTAINS, POOLS, PONDS, CASCADES,WATERFALLS, AND STREAMS. MODERN WATER FEATURES ARE TYPICALLY SELF-CONTAINED, MEANING THAT THEY DO NOT REQUIRE WATER TO BE PLUMBED IN; RATHER WATER IS RECYCLED FROM EITHER A POND OR A HIDDEN RESERVOIR, ALSO KNOWN AS A SUMP. THE SUMP CAN EITHER BE CONTAINED WITHIN THE WATER FEATURE, OR BURIED UNDERGROUND (IN THE CASE OF AN OUTDOOR WATER FEATURE).
