Irrigation System, Tailwater Recovery (447): A facility to collect, store, and
transport irrigation tailwater for reuse in the farm irrigation distribution system.
The reservoir will trap sediment and sediment attached substances from runoff
waters. Sediment and chemicals will accumulate in the collection facility by
entrapping which would decrease downstream yields of these substances.
