Typical design Constructed stormwater wetlands are relatively large end-of-pipe facilities that aim to use multiple treatment methods (for example sedimentation, biological and chemical processes) to remove pollutants from stormwater. The …
Typical design Although sedimentation facilities can take different forms, they all have in common that their primary aim is to use the process of particles settling to the bottom of …
Typical design Biofilters are facilities where water flows vertically through a vegetated filter media. A combination of physical, chemical and biological mechanisms remove pollutants from the stormwater as it passes …
Typical design Infiltration facilities is rather a process than a specific type of facility. Infiltration facilities can cover a range of different types and designs. Their primary aim is to …
Typical design Swales are vegetated (usually with grass) ditches with gentle side slopes that are commonly placed alongside streets but can be used in other areas as well. They usually …
Typical design The general feature of a retention/detention facility is that it provides a storage volume for water. Thus, it can buffer peak flows (Q): Qstormwater = Qin > Qout. …
Typical design Green roofs are an alternative to traditional roofs. One goal is to intercept rainfall directly where it lands and both reduce the runoff volume generated and delay the …
So far in this course activity, we have looked at challenges associated with pipe-based drainage systems and the problems with stormwater pollution. In recent decades, there has been increasing attention …
In this movie, Ico continues to talk about some of the shortcomings of pipe-based systems and mentions the so called Sewer system. This system is based on the same network …
Welcome to the second week of the course! This week we will take a look at transitioning from pipe-based to green urban drainage, the reasons to make this transition and …
Pipe-based systems have been a common way of dealing with stormwater in urban areas for many years. However, recently there has been more attention for the limitations that these systems …
