Hardscapes Water Features A well-placed water feature can enhance the environment aesthetically and acoustically. Choosing the right water feature depends on how much you want to be involved with the maintenance. A fountain on the patio or a waterfall with a pond built into your hardscape requires little upkeep. A pond with fish and aquatic plants will require some on-going attention. Water features can also be used as a solution to a drainage issue by creating a pond or stream that is also pleasing to the eye.
