Full Description

The Hill Canyon Treatment Plant (HCTP) provides tertiary-level wastewater treatment for the City of Thousand Oaks. It was constructed in the 1960s with major improvements over the following decades. As part of the City’s HCTP Master Plan (2020), the need to develop flexibility for biosolids handling was identified, whether that be trucking biosolids directly from the dewatering press discharge conveyor and depositing it into hauling trailers or conveying the biosolids to an adjacent location to be managed and processed/hauled at a different time. The vision is to utilize an alternate conveyance and storage facility in the drying beds to allow for staff utilization at night on different tasks rather than monitoring the biosolids load in the hauler/trailer. City is seeking an alternatives analysis document outlining the different conveyance system products and alignment/orientations and sizing, as well as preliminary layouts and details on the required storage facility options to temporarily house the biosolids, which will be trucked or processed later. Construction ready plans and technical specifications will be prepared for the recommended conveyance and storage system.
