Rock Creek Force Main, Anne Arundel Co

Wallace Montgomery: Rock Creek Force Main

Performed a condition assessment for 1,000 LF of a problematic, 37-year-old, 18″ PCCP sewer force main, blow off and air relief valve in vault through a steep wooded easement immediately upstream of the Rock Creek sewer pump station.  Evaluated four force main replacement and alignment alternatives including rehabilitation by CIPP lining, horizontal directional drilling, parallel relocation in existing easements, and relocation to an entirely new alignment.
