Flyrate excellence understand the important of proper drainage design as its basic objective is in reduction and/or elimination of energy generated by flowing water. The destructive power of flowing water, increases exponentially as its velocity increases. Therefore, water must not be allowed to develop sufficient volume or velocity so as to cause excessive wear along ditches, below culverts, or along exposed running surfaces, cuts, or fills.Flyrate excellence professional engineers with years of experience on drainage system and design with record of accomplishment of these process are cognizant of two main criteria on drainage to be effective throughout its design life to be:
- It must allow for a minimum of disturbance of the natural drainage pattern.
- It must drain surface and subsurface water away from the roadway and dissipate it in a way that prevents excessive collection of water in unstable areas and subsequent downstream erosion.
