ISP Reconstruct Glycol Treatment System

Work includes the construction for corrective action to be taken to the existing glycol treatment system. Modification 1: Replace or modify a weir structure that is used to divert stormwater to the GTS to prevent or reduce stormwater leakage and bypass of the GTS to the extent practicable. Modification 2: Modify the controls of the GTS influent pumps to limit fluctuation in pumping rate and maximize the hydraulic retention time within the gravel bed to promote biological activity. Modification 3: Install control valves on the GTS supply lines to allow more uniform flow distribution within the gravel bed.
