Brown and Caldwell and Black & Veatch to Design OCSD’s Largest Project to Date.

OCSD’s Capital Improvement Program (CIP) is a long-term plan to rehabilitate, replace and update the agency’s regional facilities.  The largest project of the program is the new temperature-phased anaerobic digestion (TPAD) facility at the Huntington Beach Plant. A team from Brown and Caldwell and Black & Veatch have been awarded the design contract for the facility.

The $300 million project involves the construction of six new thermophilic digesters and six new Class A batch tanks at Plant No. 2, allowing the facility to generate Class A biosolids that meet U.S. EPA guidelines for land applications including fertilizer on farms, vegetable gardens, and for residential use as compost or fertilizer.
