Dumpster rentals are provided using large containers that are delivered and then at a later date picked up to be emptied. The dumpsters for rent range in size from 15 to 40 cubic yards and are usually provided by Waste Pro. Construction and demolition customers use open top containers that are emptied on an on-call basis. Permanent commercial customers use either open top containers or closed compactor containers and they are serviced on either an on-call or a scheduled basis.
