BACKGROUND
The Activated Sludge Plant at the Orange County Sanitation District (OC San) Plant No. 2 uses chain and flight mechanisms to collect sludge settling along the length of the clarifiers to hoppers at the upstream end. The collectors, which include 2,900 feet of plastic chains and 160 flights per clarifier are subject to degradation and wear. Although the collector mechanisms were replaced in six of the clarifiers in 2020, the collectors in the remaining six clarifiers have been in service since 1996.

* Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder
