Wash-out trays are designed to be placed under a portable toilet while on the job-site. When our service driver arrives to clean the units at your location, all of the runoff wash water is collected in the tray and can then be removed by the vacuum hose.
These trays are a requirement if your project is going to be a LEED certified project. For more information about LEED certification, please visit the website for the US Green Building Council. www.usgbc.org
