Thornton Avenue Low Flow Diversion

A low flow diversion project was completed this year. This system will divert dry weather low flow from approximately 268 acres that represent Thornton drainage area. Dry weather low flow will be intercepted by a 9-inch berm constructed at the invert of the existing storm drain to direct the flow to the diversion structure.

At the diversion structure, a bar screen will separate debris and runoff will flow to a 5 feet diameter sump well where it will be pumped to a near by sewer system, and eventually to the Hyperion Treatment Plant.
