The collection and treatment of storm water for reuse is a growing market that enables collected storm water to be used for a variety of applications including irrigation,  non-potable applications (toilet flush water), process water or cooling tower feed water (industrial), and occasionally even for potable (drinking) water.

 

Complete control systems that capture, measure, control, and deliver harvested rainwater treated as necessary for the intended use. Dataloging of system parameters enables the user to monitor the amount of water processed so that ROI savings can be calculated.

 

The most popular use for harvested storm water is for irrigation. Approximately 34% of all water use in the United States is for irrigation.

Storm Water Reclamation

Collected storm water quality varies depending on the source (rooftop to storm water culverts), some collected water can be simple to treat and others may require a WIND controller for correction of the water quality parameters such as pH, suspended solids and disinfection. The water quality can be usually be determined by simple tests.

 

One common application for harvested storm water is for toilet flush water.  This application has become popular with schools and other small institutional facilities.  A dye will normally be injected into the water collected to differentiate it from Potable water.  These systems can be more complex if there is a tie in with city water systems.

 

In the Industrial environment, irrigation costs are generally insignificant compared to the costs for water used for cooling and process water.  These applications often account for 80-90% of industrial water use. These systems are generally the most complex, with enhanced filtration, disinfection, recirculation and water quality monitoring, but as the above example, there are many specialize complete turnkey systems.
