The features of a water feature can be as diverse as the price points, but most commonly they include a waterfall, fountain, and koi pond. The amount of features you want to include will depend on your budget and your personal taste.
Choose the right type of water feature:
A waterfall is the most common type of water feature. It is a must-have if you want to make a backyard look more relaxing or natural. They can be created out of rock, concrete, tile, or other sturdy materials.
You may also want to consider adding a fountain to your backyard for variety's sake. A fountain is used to add interest and depth into an otherwise ordinary looking landscape by creating patterns in the water that break up glare from direct sunlight or grime from pollution.
