Arlington residents, get ready to roll: A new automated trash cart system is heading your way starting next month. The City of Arlington, in partnership with Republic Services, is ditching the old-school bagged trash collection for a modernized, cart-based service slated to launch this February. New 95-gallon carts will be delivered according to a schedule that promises efficiency despite the hefty task of distributing over 100,000 units, according to the City of Arlington, Texas.
