The dimensions of stations vary greatly – from small, single-track stations in towns to large stations in metropolises. Regardless of the size, however, a station project usually consists of five areas: station forecourt, station building, platforms, bus stations and railway tracks.
Station forecourts are intended to have an inviting effect and ensure safe access for passengers to the station building and the platforms. Rainwater management systems can serve as design elements and blend elegantly into the environment. Ideally, the rainwater that accumulates should not only be drained, but also cleaned on site. In this way, the companies can later use the water to irrigate tree pits and other green spaces, for example.
The requirements for rainwater management for station buildings are usually limited to the drainage of the façade. The aim is to permanently protect the building fabric from penetrating surface water. In addition, the entrances were to be designed to be barrier-free so that every passenger could enter the station building without any problems.
In platform drainage, systems must meet strict requirements for safety and function. The design of the system also plays a subordinate role.
Platforms are usually built in such a way that the low point of the area is in the middle of the platform. This means that the rainwater that accumulates does not flow onto the electrified line and objects such as wheelchairs, prams, luggage trolleys or the like do not roll uncontrollably to the edge of the platform. Sufficient dimensioning of the drainage system quickly drains the rainwater and inhibits the risk of slipping.
There may be restrictions on the height of some platforms. Linear drainage systems in a flat design are therefore ideally suited to absorb rainwater and drain it quickly. In addition, the building materials used should not be electrically conductive. This requirement applies specifically to the protection of travelers. Live overhead lines with a voltage value of 24 kV should not become a danger to people on the platform in the event of an accident. In addition, it makes sense to clean the rainwater before draining it so that it can be returned to the water cycle without hesitation.
Compared to the requirements of safety and function, the design of drainage channels on platforms plays a subordinate role. Nevertheless, the external appearance of the station as a public area is associated with a certain reputation. The design of the systems should blend into the overall appearance of the station.
The bus station is often located in front of the station forecourt or at the rear exit of the station. From mini buses, midi buses and standard buses to coaches or articulated buses – there is a lot of traffic here.
Rainwater management systems in these areas must not only drain rainwater quickly, but also withstand immense loads and high frequencies caused by heavy traffic.
Operational safety is the be-all and end-all when it comes to track drainage. The water must be drained safely to avoid waterlogging and erosion. In addition, however, the pollutants from the rainwater must also be filtered and retained. Only then can the water infiltrate into the environment. Treatment is carried out in a decentralised treatment system. Infiltration elements with technical filter substrate along the track bed are suitable, near-natural and low-maintenance systems for this purpose.
