What will happen if we don’t survey the Strategic Road Network

Road drainage surveys involve the inspection and evaluation of the drainage system along a road or highway to ensure that it is functioning properly. The survey typically includes an assessment of the road’s drainage infrastructure, such as gutters, culverts, catch basins, and stormwater detention ponds.

The purpose of a road drainage survey is to identify any potential drainage problems and to ensure that the system is adequately designed to handle stormwater runoff. The survey may include visual inspections, measurements, and flow rate calculations to determine the capacity of the drainage system and to identify any blockages, obstructions, or damage to the infrastructure.

Road drainage surveys are important for several reasons, including:

• Preventing flooding: The primary purpose of road drainage is to prevent flooding on roads and surrounding areas. A proper drainage system is essential for carrying rainwater away from the road surface and preventing water from pooling and causing damage or safety hazards.
• Ensuring road safety: Poor road drainage can create hazardous conditions for drivers, such as standing water on the road surface, which can lead to hydroplaning or reduced visibility. A drainage survey can identify potential safety hazards and help prevent accidents.
• Preventing road damage: Water is one of the most damaging forces to roads, as it can penetrate and weaken the road surface, causing cracks and potholes. A proper drainage system helps prevent water from causing damage to the road surface and can prolong the lifespan of the road.
• Cost-effectiveness: A drainage survey can identify potential drainage problems before they become major issues, which can save money in the long run by preventing emergency repairs or costly road closures.

Overall, road drainage surveys are an important part of maintaining safe and efficient roadways, as they help to prevent flooding, reduce the risk of accidents, and prolong the lifespan of the road infrastructure.
