The Mercedes-Benz stadium adopted a number of water-reducing strategies before it opened. Among these initiatives are the following
- Installing high-efficiency toilets that use less water than those required by government regulations;
- Xeriscaping green space, including planting drought-resistant plants;
- Selecting mechanicals, such as boilers and HVAC systems, which use water more efficiently than comparable systems; and
- Installing a 680,000-gal cistern to collect rainwater, which then can be used for cooling the facility or irrigation.
Additionally, waterless urinals were installed throughout the facility.
One traditional urinal can consume more than 35,000 gal of water per year. It is hard to count how many urinals are in the average sports venue in the U.S., much less determine how much water they consume because many stadiums use trough urinals. These urinals can accommodate three to six users at one time.
Further, some stadiums have installed a combination of traditional urinals and trough systems. However, whatever the situation, the amount of water used can be millions of gallons. One of the most effective ways to reduce those numbers is to install no-water urinals.
“When we were looking for ways to become Platinum LEED certified, we realized very quickly that no-water urinals would be a a key part of the puzzle,” Jenkins said. “We looked at several urinal technologies that reduce [water] consumption, including pint flush urinals, but we decided that no-water [urinals] was the way to go.”
