The new WMAC vehicles are Liquid Natural Gas vehicles. That means that they do not use diesel; they use natural gas. These vehicles are cleaner burning and were provided to the District at no additional cost. The vehicles are also semi-automated which means that the driver will be standing inside the vehicle and will get out at every stop in order to bring the cart to the automated arm of the vehicle; the automated arm will pick up and empty the contents of your cart into the collection vehicle. Carts no longer need to be placed 3 feet apart.
