Pump & Treat is one of the more common forms of groundwater treatment, pumping groundwater through a treatment system, then discharging either back to ground, or into the drains.
Treatment systems vary significantly in type and size, the specifications depend upon the contaminants which need to be treated, the rate the water needs to be treated at, and ultimately your time constraints and budget. There are a large range of systems available from ‘carbon filters’ to ‘reverse osmosis’ , it’s just a case of finding the right one for your site.
As a general example, these systems are installed on site for weeks to months at a time, they are designed to run 24/7 requiring only minimal supervision. Strategically placed boreholes allow the groundwater to be accessed using borehole pumps which transport the groundwater to treatment system.
We’ve used pump & treat to –
- de-water contaminated excavations,
- reduce contamination levels in groundwater
- restrict contamination movement from spill
- intercept contamination before is migrates off site
- remove and separate oils from waters, allowing the oil to be re-used
