Customer Support


  • Rental Properties: We require new tenants to present a copy of the rental agreement before we can start service. We will open the account for the tenant as long as there are no outstanding collection bills for the rental property. If there is a prior outstanding balance, we require service to be opened in the property owner’s name.
  • Concord Municipal Code Section 82-37 states: “All occupied premises within the city shall have refuse service.” While the tenant, lessee, or occupant of any premises may be billed for refuse service, it is the property owner who is responsible for the bill if the tenant, lessee, or occupant does not pay, or is unable to pay the bill. Uncollected refuse accounts are the responsibility of the property owner.
  • Important: Per Concord Municipal Code CMC 62-32 (1)v., collection carts must not remain at the collection point for more than twenty-four (24) hours before pickup or more than twenty-four (24) hours after your scheduled pickup.
