Where to use the FT flume U drain
The FT Flume is a precast RCC U drain made by Trilok Infratech in Surat, Gujarat. It is cast in M50–M75 concrete in 2,000 mm units, with widths B of 600–2,000 mm in eight height families (H 900 to H 1,800 mm), rated for a 1 T/m² (10 kN/m²) live load as an open storm water drain.
The FT Flume Precast U Drain is purpose-built for projects that demand precise, controlled water flow across longer channel runs. With a hydraulically optimised profile and dense RCC construction, it is used in irrigation networks, agricultural canals, and roadside stormwater flumes.
- F/01
Durable Material
Cast from high-grade RCC with a smooth internal finish for reduced friction and optimal water velocity.
- F/02
Efficient Design
Flume profile maintains controlled, consistent flow direction — ideal for irrigation and canal lining.
- F/03
Dual Application
Used in agricultural irrigation channels, roadside flumes, and stormwater collection in sloped terrain.

| Internal clear width of the channel at the top, between the inner faces of the two side walls (front view). | Overall external width at the top of the unit, across both side walls (front view shows B1 = t1 + B + t1). | Appears to be the internal clear width at the bottom of the channel, where the tapered inner walls meet the curved floor — narrower than B because the walls taper inward towards the base. The front-view extension lines are not fully explicit. | Overall external width at the bottom of the unit, across the outer faces of the lower side walls (front view). In the typical section the bedding extends 50 mm beyond D on each side and the excavation base 300 mm beyond D on each side. | Actions |
