BEI prepared a report on the best long term use of what was once a third sludge lagoon. The study involved evaluation of all algae and primary sludge production and disposal requirements and projection of the need for use of the third lagoon in future sludge storage to see if this land could be put to better use.

BEI, in conjunction with EOA, Inc., completed an evaluation of the reliability of the City of Sunnyvale’s municipal wastewater treatment facility. To protect the beneficial uses of the receiving water of the South San Francisco Bay, the objectives of the study were: determination of treatment process stability, identification of the reliability of the plant’s mechanical systems, and identification of the need for additional reliability measures. Key factors in the study were the associated costs and benefits, as well as consequences, on the beneficial uses of the receiving water of implementing or not implementing the measures. BEI was also responsible for developing a recommended program for improving plant reliability.

This project involved an evaluation of alternatives for expansion of the wastewater treatment and disposal facilities for the Oceana Marin coastal community. The selected alternative was a sequencing batch reactor for treatment, followed by a mounded, slow sand filter system for effluent disposal in a sand dune area. The treatment facilities in fact were not expanded because of another more cost-effective project we undertook to optimize the disposal system
