One of the many ways commercial facilities are reducing water consumption is to use greywater. Greywater is referred to as “gently used” water coming from restroom sinks, kitchen sinks, showers, etc.
These facilities are often “doubled plumbed,” with greywater going into storage tanks and water from toilets and urinals discharged into sewer systems.
While some greywater may look discolored, even “dirty,” it is usually safe, even beneficial to use to irrigate vegetation, even though it should not be used for human consumption.
Because facilities that are landscaped often use more water for vegetation than anywhere else, if water can be re-used here, it can prove to be a significant water and cost savings.
However, according to Klaus Reichardt, CEO, and founder of Waterless Co. Inc., manufacturers of no-water urinals, there are some rules and guidelines we must follow to use greywater properly. Among these are the following:
“Building owners and managers should also switch to greywater friendly products,” says Reichardt. “For instance, many environmentally preferable cleaning solutions, laundry detergents, even dishwashing detergents will not affect the pH of water so they can be perfect for greywater.”
