Unique Procurement Process and Design for the City of Healdsburg's Membrane Bioreactor (MBR)/Cannibal® Treatment Plant

The City of Healdsburg's new MBR/Cannibal® treatment plant was designed using a competitive equipment procurement processes. MBR suppliers submitted proposals for equipment and design services. US Filter|Siemens was selected to supply the MBR equipment. This selection opened the door for using the Cannibal® solids management process. The City negotiated an agreement with the process supplier to guarantee the upper limit of solids disposal, with a clause to protect the City in the event that the process performance is less than optimal.This paper will present the procurement and design process for this unique way to complete the process. Cooperation between equipment supplier and design engineer was excellent, resulting in three competitive construction bids, with the selected bid within the engineering estimate.The project is currently nearing completion and startup is commencing mid-December. Additional data may be available at the time of the presentation.
