The Payoff of Recycling Nursery Water

Pitton, B.J.L., Oki, L.R., Haver, D.L., Johnson, G.E. (University of California Davis)

A large nursery in southern California installed an irrigation runoff capturing system to reduce water expenses and the production quality if the water supply was interrupted. They use a large amount of water, about 1,000 ac-ft/yr at a cost of $944 per ac-ft, so it is also a large expense. In two years, the nursery reused 1,022 ac-ft or about 50% of total water used for irrigation. For those two years, recycling irrigation runoff water saved $809,000. Even though the cost of the project was $900,000, it was recovered in the first year by grants, rebates, and water savings.
