F. E. Weymouth Water Treatment Plant Raw Water Bypass - Final Design
Document Type
NOE - Notice of Exemption

Document Description
The Metropolitan Water District of Southern California is proposing to prepare final design of a new raw water bypass stubout at the Weymouth Plant. Work on the finished-water side of this connection will be designed and constructed separately in the future. In the event of an extreme event or emergency that impacts the Weymouth Plant's ability to treat water, it may be necessary to bypass the Plant and deliver untreated water into the distribution system. Currently, at the Weymouth Plant, both the raw water inlet pipeline and the Finished Water Reservoir outlet have been blocked stubouts. In an emergency, a short pipe spool could be inserted to connect the two pipelines and bypass the Weymouth Plant. Metropolitan proposes to move forward at this time to take advantage of construction efficiencies and a planned shutdown of the Plant inlet line, and to increase system reliability under emergency conditions.
