The Fine Print: If you are in a cart conversion area, your new trash cart will be deliver during your two week cart conversion period. To find out when this will occur, call 311 and ask for Solid Waste Management Customer Service. If you are in a non-cart conversion area, please allow 4 to 6 weeks for your new cart to be delivered. Continue to set out your existing cart as you normally do, then on one of your upcoming trash collection days our crew will empty and then replace your existing cart with the new smaller cart. Carts are not available for residents with manual trash collection.
