Information from the Solid Waste Department


Caltrans and Trinity County have partnered again for Trinity County residents to dump their household waste for free in March! Trinity County households qualify to dump two cubic yards of waste at one of the nine Trinity County dump sites. This event may end early due to limited capacity. This dump event is managed using vouchers and is for HOUSEHOLD WASTE ONLY. Please email to receive your voucher and reference “Voucher” in the subject line. Please also include your mailing and physical address, along with a current phone number in the body of the email. Numbered vouchers will be issued by return email PDF attachment and must be presented to the attendant at time of disposal. If you prefer to pick up your voucher instead of receiving it by email, please advise at the time of request.
