Where should the subsoil pipe discharge in a plumbing design?

• A. Into a sump
• B. Into a drainage ditch
• C. Into the main sewer line
• D. Into a stormwater system

Answer: (A)

The subsoil pipe is designed to address groundwater drainage and ensure that excess water beneath the soil surface is effectively managed. Discharging into a sump is a suitable option because sump systems are specifically engineered to collect and manage excess water or groundwater that accumulates in a low point, typically below the surface. When the subsoil pipe discharges into a sump, it allows for controlled pumping of water to prevent flooding or saturation in the vicinity of the foundation of a structure. This process helps maintain soil stability and ensures that water does not compromise the integrity of the building. The sump can then direct the collected water to an appropriate drainage outlet, such as a stormwater system or drainage ditch, depending on the design requirements and local regulations. While other options like discharging into a drainage ditch or a stormwater system are valid for certain types of systems, they may not provide the same level of control and efficiency in managing groundwater, which is essential when dealing with subsoil drainage specifically. Moreover, discharging directly into the main sewer line is generally not permissible for subsoil drainage due to potential overload and backup issues in the municipal sewer system. Therefore, discharging into a sump is the most effective and appropriate method for managing the water collected by the subsoil pipe.
