Pipeline & Tank Hydrotest & Water Treatment

Envent leads the nation in the on-site treatment of water used for pipeline hydrostatic testing (aka pipeline hydrotesting) in the petrochemical and refining industries.  We design our treatment systems to remove specific contaminants and meet all discharge permit requirements for general water quality, volume and flow rate.  Envent manages the largest fleet of tank & pipeline hydrotesting equipment in North America.

Envent has the mobile water treatment equipment to meet any water-treatment challenge under any conditions. Our hydrotest water treatment services include permitting, equipment delivery and set-up, media loading and extraction, system operation, media disposal, discharge monitoring and final project reporting. Our systems employ activated carbon, zeolite and clay media, dissolved air flotation units, air strippers, particulate filters and advanced oil/water separators.

Envent mobilizes its teams 24/7 to pipeline stations, terminals and refineries to perform treatment of the water following the pipeline hydrostest.  We work with your environmental engineers to acquire the necessary NPDES or POTW permits, spec out the right equipment, treat your water, sample and work with the laboratory to ensure analytical testing requirements are met, and file discharge reports as needed.  In short, we do it all – which is exactly what you should expect from a specialist!

If you’re an engineering firm, you will appreciate the support you get from our engineers and project managers to spec-out equipment and draft safe work plans and operations manuals.  Please contact Envent engineers to help scope your next tank or pipeline hydrostest project.
