If your design is restricted by size or if you have concerns about safety, a pond-less water feature may be the answer. Pond-less features consist of a hidden basin which contains a water reservoir and pump that provide the mechanics for dramatic waterfalls, cascading water courses, or splashing fountains. The reservoir is often covered with a layer of polished and coloured gravel that allows the water to return to the reservoir. Use your imagination, the possibilities for this type of feature are almost endless.
