Rainwater Harvesting & Agricultural Infrastructure in Granbury, TX

In parts of Hood, Parker, and Erath Counties, traditional water sources such as wells or municipal lines can be limited, unreliable, or expensive to extend to remote structures. In North Texas, where average annual rainfall is roughly 35 inches, the roof of a barn, equipment shed, workshop, or indoor arena can represent a substantial untapped water resource.

We design and install the high-capacity collection infrastructure required to support large-scale rainwater harvesting systems for ranching and agricultural operations.

Turning barns, arenas, and outbuildings in Granbury and surrounding North Texas communities into functional water assets.

The Math of Agricultural Runoff

Large-span metal buildings shed an enormous volume of water. On a typical 40×60 barn, one inch of rain can produce roughly 1,500 gallons of runoff.

Annual potential: Based on local rainfall averages, that single structure can collect more than 50,000 gallons of water per year.
Surge factor: Because metal roofs shed water quickly, these systems must be designed to handle a rapid surge during intense North Texas storms without overshooting the gutter or restricting flow into storage.

Engineering for High-Volume Collection

Agricultural rainwater harvesting requires more than a standard residential gutter system. It requires collection infrastructure capable of handling fast, high-volume runoff from large roof spans.

Larger collection profiles: We use larger 6-inch seamless profiles and heavy-duty box gutters where needed to contain high-velocity runoff from metal roofing.
High-flow collector boxes: To feed a storage tank effectively, the transition must remain unrestricted. We fabricate custom collector boxes and conductor heads that allow water to move efficiently into the downspout system.
Debris and silt management: For livestock, irrigation, or equipment use, cleaner water is important. We commonly recommend first-flush components so the roof can be rinsed before water enters storage.

Advanced Downspout and Offset Geometry

Standard downspout elbows are often restrictive. We use fabrication techniques that improve vertical flow while maintaining a cleaner finished appearance.

Broad sweep geometry: We form round and rectangular elbows with broader sweeps to create smoother transitions and reduce the clog points common in tight, factory-crimped elbows.
Reinforced connections: Where sections join, we form reinforced connections to increase rigidity and reduce the separation that can occur over time with expansion and contraction.
Architectural offsets: Custom-formed transitions allow vertical runs to maintain a straight, supported alignment around stone ledges, trim, and other architectural features without interrupting water movement.

Ranching Infrastructure Evaluations

Whether you are trying to supplement a struggling well, reduce dependence on hauled water, or design a more capable system for a new build, we provide technical evaluations for ranching and agricultural facilities.

We review roof geometry, runoff volume, and collection goals to design infrastructure that turns outbuildings into functional water assets.
