Strad’s Surface Equipment team specializes in containment, fluid management systems and spill prevention as well as turnkey project management. Our team is highly trained and experienced at mobilizing and demobilizing tank farms. Our team will safely and efficiently coordinate all logistics for the transportation of equipment fluids and waste disposal on the well-site.

Suction lines have an optional manifold that can be installed to allow multiple vacuum trucks to hook up to remove fluid faster. Also, circulating lines have an optional manifold that can allow one pump to keep the fluid moving in all the tanks. Strad has added pump mounts to all of our tanks in order to use multiple pumps if required or to allow any tank to have its own independent pump.
