Before your dump run in Houston

Call ahead. Hours change on holidays and in bad weather, and some sites stop taking loads before closing time.
Check if it's residents only. County and city collection stations often ask for a driver's license or utility bill.
Sort your load. Tires, mattresses, appliances and brush often cost extra or go to a separate pile.
Cover and tie down your load. Loose loads are dangerous and many sites charge extra or turn you away.
Keep hazardous waste separate. Paint, chemicals, batteries and motor oil usually need a household hazardous waste site.
