To avoid most maintenance problems with Fountains and Retention Ponds, you need to take a pro active approach. These areas need to be clean of all and any debris that might restrict water flow. Never dump clippings or branches that can reduce the effectiveness of drainage in your retention areas. Many maintenance calls for problems occur in the aftermath of thunderstorms and power interruptions, which stops the work of the water cleaning equipment. It’s a good idea to schedule a maintenance check after a major storm.
