Add and modify underground storage to your drainage system model.
Stormwater control underground storage is a hidden system that captures rainwater runoff and temporarily stores it in underground chambers, releasing it gradually to prevent flooding and manage water flow.
Sketch an underground storage area along with your existing gravity pipe network and assign parameters that define depth, capacity, and connectivity to the drainage system.
Important: All drainage objects within a release (including ponds, underground storage, and channels) use a unified version for easier management. This object version implementation allows for methods to design a drainage system across teams without updating a drawing to a software release. An object's features are contingent on what version it in which it was created in what version it is open. Objects can be upgraded on command to leverage features in newer versions of Civil 3D.
