Trucks go along each route to collect each stream of material separately (one for waste, one for recycling, and one for organics). The order in which the trucks go along the routes can change without notice, especially as new areas are added in the Harmony community.
The waste management company is contracted to collect your waste on collection day, but the time is not specified. If you place your carts out after 7 AM and the truck has already passed your house, the material that truck was collecting will not be picked up since the next trip will be for a different stream of material.
