CGRS sump testing goes waterless, faster with Dri-sump® method

Instead of water, the Dri-sump® system uses a food-grade, pH-neutral, nonpetroleum vapor aerosol injected into the sump, filling a 300-gallon sump in 10-15 seconds. An air generator pulls the gases from the sump into a viewing chamber connected to a Vapor Stimulator Tube (VST), where a laser delivers the verdict: a “dot” means no leak is present and the sump passes the test; a green “line” means the sump is leaking.
A mobile app captures the laser result, time stamps it with the GPS location and uploads it into Leighton O’Brien’s data capture software for analysis and reporting. The laser line pinpoints where the leak is, so no additional testing method – only repairs to the containment system – is necessary.
Other benefits of Dri-sump® testing include:
- Less dispenser downtime
- Increase number of containment tests per day
- The vapor dissipates within 10 minutes after the test is completed
- It is the only test that can be conducted in frozen soils, high water table conditions and any backfill soil type
- Regulatory acceptance as an alternative to costly hydrostatic testing
“Dri-sump is an innovative technology that allows CGRS to deliver a better solution to our compliance customers,” said Mark Shaw, CGRS Compliance Services Operations Supervisor. “It speeds up containment testing exponentially, saving customers time and money while they’re still adhering to compliance regulations.”
