A general contractor faced significant environmental compliance challenges due to contaminated groundwater at a construction site. High concentrations of suspended solids, iron, and other pollutants meant the water required careful pre-treatment before it could be safely discharged into the local wastewater system (POTW).
The site’s high water table added complexity, requiring continuous water management at a substantial rate of 350 gallons per minute.
Using detailed site data, E-Tank’s engineering team quickly designed a robust filtration system capable of meeting the demanding flow rate and stringent contamination removal requirements. The integrated solution used a strategic combination of Weir Tanks, Bag Filters, Cartridge Skids, and Multi-Media Filtration Vessels.
When new contaminant data was provided, it required rapid modifications to our system, and we promptly adjusted the design to meet the revised criteria. In addition, we were able to provide the client with:
Installing the filtration system in January presented exceptional challenges, with temperatures plunging below 0°F. Despite the frigid conditions, our team successfully initiated the system without delays. Additionally, the initial two months revealed substantially higher levels of suspended solids than anticipated. This led to more frequent filter replacements, which E-Tank effectively managed without compromising performance.
The project remains active, demonstrating E-Tank’s ability to maintain consistent performance, reliably managing groundwater while effectively removing contaminants. The client benefits from peace of mind, knowing their environmental compliance needs are continuously met, even under challenging circumstances.
