Overview
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 performs reliably in irrigation networks, agricultural canals, and roadside stormwater flumes — even in challenging terrain and high-rainfall conditions.
- 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.

Size range: B 600–2000 mm × H 900–1800 mm. The dimension tables list 104 standard sizes in 8 height families (H 900, H 1000, H 1200, H 1300, H 1400, H 1500, H 1600 and H 1800), from 600 × 900 to 2000 × 1800 mm.
Each precast unit is 2000 mm long (L = 2000 mm), so a 100 m run takes 50 units.
Live load 1 T/m² (10 kN/m²).
Typical applications: Storm water drains; Power ducts; Road crossings, as a replacement of pipe culverts.
