Tank Sump Upgrades

Some UST regulations require all components of the UST system to be “product tight” and be periodically tested for tightness. Studies funded by the state of California determined between 25% and 50% of underground tank sumps were leaking. If your tank sumps require upgrading, consider using CSI Field Service technicians on your next job. Our technicians are experienced in the field of FRP and carry proper OSHA training for confined space entry.

If your tank sumps require upgrading from a non-sealed model to a watertight and testable model, the procedure is simple and effective:

  1. Cut away existing top
  2. Install a new watertight reducer and watertight lid inside the existing top then seal to existing piping
  3. Perform tightness test

Our trained staff can provide turbine and fill/vapor sump lids and all are watertight.
