Rainwater harvesting is ideal for farm animal drinking water and agricultural and landscape irrigation, as it is salt free, easily attained, and reduces groundwater depletion and pumping from local streams. Rainwater can be collected from rooftop surfaces of barns, clubhouses, greenhouses and equipment storage buildings. During summer months, properties around the world often experiences quick, hard rainfalls. Such rain events produce too much water in too short a time for the ground to absorb, resulting in most of the rainwater being lost to runoff.
Rainwater harvesting systems are capable of collecting the rainwater from roof surfaces during such rainfalls. The heavy storm’s rainwater can then be reapplied to the field at a suitable rate to promote water infiltration. Frequently, livestock buildings allow rainwater from the roofs to flow into areas occupied by animals. This situation allows rainwater from these facilities to become contaminated by fecal matter resulting in increased manure slurry that must be managed. If rainwater from these facilities is harvested, it can be used for watering livestock and washing down facilities and animals. Harvesting rainwater from these facilities can reduce the amount of waste water created as well as decreasing the demand on wells and other water supplies.
