Life Expectancy: Some of these are hundreds of years old, but may not still function depending on the water source and power source. Modern, plastic versions can be expected to last 5-10 years with adequate care.

Pro: These can look very pretty, and the moving water reduces the opportunity for species like mosquitoes to breed in the water. Moving water can be heard by wildlife and because of the aeration will remain fresh instead of going stagnant like pond or birdbath water easily can. You can buy these at most garden supply shops, online, or you can get creative and build one yourself.

Con: These need routine maintenance and will get blocked up very quickly if kept in shade. If kept in a sunny location (away from trees) then evaporation rates will be higher. Evaporation in general will be higher than with other options, meaning it may need to be refilled more often. As these are often above ground with pipes and motorized parts, they can be susceptible to damage during heavy freezes. These may pose a drowning hazard to children and small animals, who can drown in as little as 2 inches of water.

Solution: To prevent drowning you may want to include a fitted grate over the catchment part of the fountain. You can make a child and butterfly-friendly feature by building a pebble fountain which can be set into the ground or can be built above ground with old pottery or anything that will safely hold water. Service regularly by cleaning out algae, leaves, sticks, and any other materials that might block water flow.

Materials: Plastic tubing, filters, and potentially plastic body. Other materials like stone or concrete can also be used. A power cord and/or solar device will be needed to power the water feature.
