1. Install a Rainwater Harvesting System for Sustainability Rainwater harvesting is the practice of collecting, storing and treating rainwater to be used onsite, rather than letting it runoff to the storm system. It can provide an independent, sustainable and free water supply that can be used for flushing toilets, irrigation, or other non-potable applications. With the right rainwater harvesting system, a commercial building can reduce its environmental impact and prevent erosion from downspouts and gutters. Collecting rainwater may also help minimize or eliminate flooding in areas around the property. Installing a water harvesting system is a great way to reduce utility bills associated with water consumption. It can also reduce reliance on water from utilities. Imagine if all businesses had a rainwater harvesting system, then water consumption would be reduced and used for other important needs. Fresh and potable water continues to be scarce, which can make it more challenging to keep landscaping watered and toilets sanitary. Rainwater harvesting may be an ancient method of collecting water, but it has been enhanced with modern technology and innovative, cost-effective methods to work well in commercial and institutional settings. With the right system, the rain harvesting system could be customized as a primary or backup source for applications that demand high volumes of water , such as toilet flushing, irrigation and cooling tower make-up. If you want to earn a LEED certification, and gain a better reputation in the community, apply sustainability practices such as harvesting rainwater for reuse. By using a water harvesting system , you can significantly reduce municipal water and sewage fees. Some towns and cities even offer incentives to establishments with a rainwater harvesting system that minimizes stormwater runoff.
