Rock Creek Trunk Capacity Upgrade Phases 1 & 2

Status Updates
In Design or Study

Phase 1 of this project includes upsizing approximately 1,910 lf of 18″ diameter sanitary trunk line to 24″ diameter trunk line, commencing where Onion Flats trunk line upsizing (by CWS in 2016) was completed and running south to the first manhole beyond the P&W Railroad ROW.

Phase 2 will include replacement of approximately 2,600 lf of existing 15” diameter RCP sanitary sewer trunk pipeline with 18” diameter HDPE sanitary sewer trunk line between P&W Railroad right-of-way and Oregon Street,  Replacement is needed due to existing system deficit condition and to provide capacity for future development.  Anticipate need for replacement to be near term (within 5 years).

Additional details about this project are included in the 5-year Capital Improvement Plan (CIP).
