What Does Outfall Mean In Construction?

The outfall is the point where water from a structure, such as a drainage ditch or storm sewer, discharges into the receiving environment.

In construction, an outfall is often the outlet for stormwater runoff from a site. The outfall must be designed to safely convey the volume of runoff without eroding the surrounding landscape or causing flooding.

What Is An Outfall Structure?

An outfall structure, also called a discharge structure or diffuser, is a device used to release wastewater from a treatment plant, sewer system, or other source into the receiving environment.

The outfall discharge may be to surface water (a stream, lake, or ocean), to groundwater, or to evapotranspiration.

The effluent from the facility is piped to the outfall structure where it is released. The effluent flow may be gravity-driven or may be forced by pumps.

The type of outfall structure used depends on the receiving environment, the effluent characteristics (flow rate, temperature, pollutants), and other factors such as tidal influences and wave action.

What Is The Difference Between Outlet And Outfall?

An outlet is a point where water exits a system, while an outfall is the structure through which water leaves that system.

Outlets are usually located at the lowest point in a system, while outfalls can be located anywhere along the system’s length.

Outfalls are also typically larger than outlets, and they may be designed to handle greater volumes of water.

What Are Outfall Locations?

In general, an outfall is the point where water (or other liquid) empties into a larger body of water.

Outfall locations are often determined by sewerage system design or by the receiving body of water’s geography.

For example, most cities have a single outfall location where all of the city’s sewage enters a river or ocean.

However, some cities have multiple outfalls due to the geography of the receiving body of water or the city’s sewerage system design.

What Is Outfall In Hydraulic Structure?

An outfall is a structure used to discharge effluent from a drainage system, sewer or watercourse.

It usually consists of a pipe or channel that conveys the effluent to a natural body of water, such as a river, lake or sea. Outfalls can also be used to discharge effluent into groundwater.
