ABSTRACT:
The present invention is process for irrigation of a golf course, which involves monitoring reclaimed water, and treating it when necessary to avoid harmful effects to plantlife. The reclaimed water is tested with a plurality of monitors to obtain results for water quality characteristics, including: pH; residual chlorine; and, sodium. These results are inputted to a computerized data handling system for data collection, storage and analysis for comparison to predetermined acceptable ranges for water quality characteristic, and to show any deviation from said acceptable ranges. Either alarms are set off or treatment occurs or both, when deviations are observed. Treatment includes a dechlorination system to correct active chlorine. Other important monitors may be included for one or more of the following: hardness; turbidity; alkalinity; conductivity and nitrates.
