State-of-the-Art Equipment and Processes

Petro Waste Environmental is dedicated to leading the industry in facility safety and regulatory compliance. We work with respected engineering firms to create state-of-the-art facilities using proven technology, including automation and monitoring systems that supplement our on-site personnel.

How we handle the waste we receive depends on its liquid content:


  • Dry materials go directly into a disposal cell.
  • Wet solids are placed inside a drying cell until enough water has evaporated for them to be transferred to the disposal cell.


Pumpable fluids are passed through shaker screens and hydro-cyclones to pull the solids out of the liquid, and then placed in a centrifuge to pull the fine solid particles out of the fluid.

  • The solids are then sent to a disposal cell and the water disposed of in a saltwater disposal facility, leaving only the saleable oil.

Scientifically Advanced Disposal Pits

Traditionally, disposal cells have been constructed with clay soil liners to prevent the waste from leaching into the groundwater, but Petro Waste Environmental LP engineers its disposal cells to exceed these minimum standards. Further, we hold our personnel to the highest standards of safety in their training and required gear, and we choose the safest and best locations to construct our facilities.

The layering of the cells, from the bottom upward, utilizes not only a re-compacted soil liner, but also dual synthetic liners sandwiched around a leak-detection system and topped by a leachate collection system.

  • Compacted soil liner
  • Synthetic liner
  • Leak-detection system
  • Additional synthetic liner
  • Leachate-gathering system
  • Thick layer of protective soil

This redundancy is designed throughout our systems to prevent and detect leaks at every stage. Additionally, we place groundwater monitoring wells around our facilities in order to monitor and report groundwater quality and any changes that may occur.
