sekaviemäröintijärjestelmä

Sekaviemäröintijärjestelmä is a type of stormwater management system designed to mitigate the effects of urban rainfall runoff and excessive groundwater infiltration. The system involves the creation of artificially flooded areas, typically using natural or constructed wetland habitats, to slow down and filter stormwater run-off.

The system is based on the principle of allowing floodwater to enter the soil for a short duration, thus recharging aquifers and reducing stormwater peak discharge rates. This approach is beneficial for flood control, as it facilitates flood storage and periods of high water flow, while simultaneously replenishing groundwater resources.

In a sekaviemäröintijärjestelmä system, surface water retention areas are created on an existing floodplain or flow path. This typically involves excavating a shallow depression, often in conjunction with shallow lake or wetland environments. Stormwater runoffs are thus captured and channeled towards the retention area, facilitating the recharging of groundwater levels through processes like infiltration and percolation.

Unlike conventional stormwater drainage systems, which often discharge run-off immediately, sekaviemäröintijärjestelmä systems allow water to slowly infiltrate the soil or be stored temporarily before discharge. By slowing down the flow, this enables additional opportunities for water filtration, before the water is either released into lower floodplains or surface water bodies.

Sekaviemäröintijärjestelmä systems can be incorporated with or be an alternative to other water conservation measures like sewers, natural wetlands, and water harvesting practices. The credibility of theconcept lies in its decadal-scale frameworks to aid flood protection, groundwater management and urban ecosystem services.

In regions experiencing unpredictable precipitation, sekaviemäröintijärjestelmä offers potential benefits for integrated environmental planning and executing post-scout designs which are onward engaged within both, rehabilitaion sequences and comprehensive urban rehabilitation schemes.
