Project Description
This construction dewatering for real estate project required excavation to depths ranging from 25’ – 35’ from surface the within a 16’ static water table. A 900 LF wellpoint dewatering system was installed in suspended segments to accommodate a staged excavation and remediation across the site. The initial system was 540 LF followed by an additional 360 LF.
A 300 CFM GWTT Vac Station is being utilized in conjunction with a GWTT Vac-fed 400 GPM Pump Can, which enables the deep drawdown of groundwater within the varying soils. The proprietary GWTT equipment was able to perform effectively in multiple configurations without suffering losses in performance during the transitions.
The project required multiple relocations to accommodate SOE and structural modifications. GWTT provided In-situ winterization of the system to allow operation during project extension due to redesign.
Additionally, the project required GWTT to provide on site treatment of the groundwater prior to discharge from the Brownfield site. The flexibility of the dewatering system, along with the on site groundwater treatment, allowed for successful excavation and civil project to occur according to plan and within budget.
