Road-Water Harvesting (Floodwater Spreaders)¶

Membranes & Advanced Filtration • Est. CapEx: Low-cost / Locally fabricated

Technical Overview¶

A low-tech solution that captures road runoff for agricultural use in semiarid regions. Floodwater spreaders guide runoff from road surfaces to adjacent farmland, increasing soil moisture and crop yields.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Membranes & Advanced Filtration
Capital Cost	Low-cost / Locally fabricated
Primary Mechanism	Low curved structures (approx. 30 cm high) built from local materials are placed alongside paved roads to intercept and spread runoff onto fields. Runoff can also be stored in borrow pits or ponds for later use, combining flood control and water harvesting.
Target Scale	Household / Village Cluster
Standard Lifespan	10 - 20 Years
