Which of the following tasks must be completed during stage construction of drainage systems?

Providing temporary connections as needed is crucial during stage construction of drainage systems because it ensures that existing drainage functionalities are maintained throughout the construction process. This task allows for the management of stormwater and prevents flooding or water pooling in areas where the drainage system is being worked on or temporarily shut down. Maintaining operational drainage reduces the risk of damage to the construction site and neighboring properties, which is essential for safety and compliance with regulations.

While bulkheading pipes, demolishing existing systems, and removing debris are important tasks in drainage system projects, they do not address the immediate need to preserve drainage functionality during the different stages of construction. Temporary connections are specifically designed to allow for continuity in drainage, thus prioritizing effective water management during the construction phase.
