Frequently Asked Questions
How do you determine the required drainage capacity?
We calculate the total discharge or water volume needed to drain by determining the area size and maximum rainfall intensity, which helps in sizing drains and selecting slope dimensions.
What factors influence drainage systems design?
Factors such as permeability and soil type, length, slope gradient, expected rainfall frequency and intensity, and total area to be drained all influence the specific design of the drainage system. To ensure accuracy, consult with our drainage design expert regarding your project.
What is a "design storm," and why it is important?
A design storm is a rainfall event used to size drainage systems, considering intensity, duration, and frequency to handle peak flows and prevent flooding.
How does surface and subsurface drainage are different?
Surface drainage involves shaping land with open drains to guide water to a specific point. However, subsurface drainage removes excess water that seeps into soil or structures below ground.
