Produced water is a continuous byproduct of oil and gas production, consisting of saline water mixed with hydrocarbons, dissolved solids, and treatment chemicals that return to the surface throughout the life of a well or field. Unlike short-term flowback, produced water requires long-term, dependable storage to support recycling, treatment, reuse, or controlled disposal. ModuTank’s produced water storage tanks provide secure, above-ground containment designed specifically for the demanding conditions of oilfield operations. Built from modular, hot-dipped galvanized steel components and fitted with chemically resistant membrane liners such as polyethylene, polypropylene, or XR-5 geomembranes, these tanks are engineered to handle high salinity and oil-contaminated water safely and reliably, as our membranes are the only wetted surface.
Produced Water Storage Tanks
Produced water presents unique challenges due to its corrosive nature, elevated total dissolved solids, hydrocarbons, and residual treatment additives. ModuTank’s membrane-lined design isolates the steel structure from the stored liquid, protecting the tank from chemical attack and extending service life. The liner systems are compatible with brines, hydrocarbons, and aggressive water chemistries commonly found in oilfield environments. Tanks can be configured with appropriate penetrations to support pumping, transfer, filtration, separation, or recycling systems, allowing operators to manage produced water efficiently across gathering, treatment, and reuse workflows.
As oilfields mature, produced water volumes often increase, requiring storage solutions that can grow alongside operations. ModuTank’s modular systems offer capacities ranging from thousands to many millions of gallons and can be expanded, reconfigured, or relocated as production profiles change. Tanks can be installed quickly on compacted soil or minimally prepared pads, making them well suited for remote locations and phased development. This scalability supports long-term produced water strategies, including reuse for drilling and completion activities, centralized treatment facilities, or interim storage prior to disposal.
With rapid installation, proven durability, and flexibility unmatched by traditional ponds or welded tanks, ModuTank’s produced water storage tanks provide oil and gas operators with a dependable solution for managing one of the industry’s most persistent challenges. Whether supporting recycling programs or long-term field operations, ModuTank delivers containment systems built for the full lifecycle of produced water management.
