PROJECT DESCRIPTION

Replace Low Pressure Sludge Gas (Biogas) (LSG) Pipe at West Point Treatment Plant from Digester 1 to 5. The LSG system is currently in operation producing 1,700-2,100
cubic feet per minute of biogas by treating the sludge materials produced through primary and secondary treatment system of the plant. However, over the years, the LSG piping system has corroded due to the H2S gas impacts and is in need of replacement.
