Automated collection is pretty rough on the garbage carts. The City purchased carts that we know will work with our trucks and are designed to withstand the stresses from the truck. The City is also assuming responsibility for maintaining the carts, so we only want to use carts that we know are strong enough to handle the stress. If we let people use their own carts, then it’s possible the automated collection truck could damage the cart. At that point, residents would likely expect the City to replace their cart. By requiring that residents only use City-provided carts, we can take responsibility for maintaining or replacing the carts if they get damaged during the garbage collection process.
