The Department of Public Works is broken down into seven bureaus. According to the sanitation department's guidelines, garbage can only be put on the street after 6am and before 8am on collection day. Containers must have lids and not exceed 80 pounds. Loose items must be in containers or tied and placed curbside for Thursday and Friday bulk collections.
