Omega restrooms from AMS Global have Jets Vacuumerator systems, which liquefy waste and paper products, and can pump to a sewer up to 100 yards away or store on board. They flush using a pint of water and have frame walls constructed from 1.5-inch tubular steel with granitized steel floors designed to never decompose. The entire trailer is made from steel, composite fiberglass panels and aluminum. The chassis has been tested at over 16,000 pounds capacity and incorporates four 4,000-pound-lift remote-controlled jacks. The trailers lower to the ground, reducing liability issues and making ADA compliance simple. 800/789-1212; www.amsglobal.us.
