Capturing the irrigation and surface run-off in a nursery or greenhouse situation is one method of a improving the efficiency of water and nutrient use. However there are a number of critical considerations that need to be addressed in any situation where recycled water is to be used. A primary question should be: is there sufficient room for the construction of an adequately sized catchment pond that has the potential to supply sufficient volume back to the system to supply production requirements? If the answer to this is yes, then the next primary consideration must be that of water quality.
