Tank installers commonly encounter ‘high water’ during the UST upgrade process. Removal of the groundwater is required to proceed with the project. In some cases the groundwater is ‘clean’ and discharge is authorized to a storm or municipal sanitary sewer system. In most cases the tank pit water is contaminated with Volatile Organic Compounds (VOC’s), sometimes dissolved and sometimes free-phase.
Field crews will commonly underestimate the water volume and its infiltration rate. Tanker trucks are a typical (and costly) solution to the problem. On-site treatment is a less costly remedy for quantities in excess of 10,000 gallons.
With proper planning the installers or consultant can reduce costs, increase margin and maintain the schedule. Sampling, regulatory approval and permitting good for everybody. By staging the liquids in a frac-tank (BAKER), samples are analyzed and proper treatment may be applied. Discharge as clean water saves time and money.
