THE MORRO BAY-CAYUCOS

WASTEWATER TREATMENT PLANT PROJECT

(And What It Means For You)

The City of Morro Bay and Cayucos Sanitary District have committed to building a new wastewater treatment plant over the next eight years.  The new wastewater treatment plant will address environmental issues, improve plant efficiency and maximize its useful life. The project is complex and will cost an estimated $32 million, most of which will be covered by increased sewer fees. The City and District recognize the many challenges posed by the construction of the new plant and want to keep you informed and involved in the process.

Morro-Bay Cayucos Wastewater Treatment Plant

The Morro Bay/Cayucos Wastewater Treatment Plant is designated as a Class III Biofiltration Plant by the Regional Water Quality Control Board (RWQCB). The plant operates under a modified discharge permit, NPDES Permit No CA0047881, that waives full secondary treatment standards for suspended solids (SS) and Biochemical Oxygen Demand (BOD). For all other operations and constituents, full secondary standards are maintained. The WWTP is committed to consistently meeting and exceeding performance requirements and providing wastewater treatment on behalf of the communities in a safe, environmentally sound and cost-effective manner.

Biosolid Composting Program

Free compost available at the WWTP

Class A Exceptional Quality Composted Biosolids are NOW AVAILABLE TO THE PUBLIC from the Morro Bay-Cayucos Wastewater Treatment Plant.  The composted material is made from treated biosolids generated from the Treatment Plant, mixed with wood chips and green waste from the local community.

The finished compost product must meet both Federal and State regulations.  It also complies with the San Luis Obispo Environmental Health Department regulations.  The compost is tested after the composting process to ensure that it meets the Federal and State standards for metals and pathogens.  The biosolids are tested annually for over 160 different constituents.  All were well below State and Federal Standards, with the majority of the constituents not being detected.

The compost is an excellent soil amendment, used like any other fertilizer from your home and garden supply.  It’s best use is as a top dressing or mulch. 

For more information, or to pick-up some compost, please contact the Public Services Department at 772-6261.
