A drainage survey is an inspection process that evaluates the condition and functionality of drainage systems, such as pipes and sewers. This survey helps identify blockages, leaks, or structural issues that could lead to water damage or flooding. It typically involves using specialized equipment, like cameras, to visually assess the interior of drainage systems. Conducting a drainage survey is essential for property maintenance and can prevent costly repairs in the future. It is often performed before purchasing a property or during routine maintenance checks. By ensuring that drainage systems are in good condition, homeowners can protect their investments and maintain a safe environment.
