BMPjärjestelmiin

BMPjärjestelmiin, often referred to as BMP systems, is a Finnish term that translates to "BMP systems" in English. It refers to a category of water management practices designed to control stormwater runoff and its associated pollutants. These systems are implemented to protect water quality in urban and developed areas by managing the volume and speed of rainwater as it flows over impervious surfaces.

The core concept behind BMPjärjestelmiin is to mimic natural hydrological processes. This is achieved through various structural and non-structural measures. Structural BMPs include features like permeable pavements, green roofs, rain gardens, bioswales, and detention or retention ponds. These are designed to infiltrate, detain, or treat stormwater before it reaches natural waterways. Non-structural BMPs encompass practices such as public education, street sweeping, and land use planning to minimize runoff generation and pollution at the source.

The implementation of BMPjärjestelmiin is crucial for mitigating the negative impacts of urbanization on aquatic ecosystems. Without effective stormwater management, pollutants like oil, grease, sediment, fertilizers, and pesticides can be washed into rivers, lakes, and coastal waters, leading to degraded water quality, harm to aquatic life, and increased flooding risks. Finnish municipalities and environmental agencies often mandate or encourage the use of BMPjärjestelmiin in new developments and redevelopments to meet environmental regulations and improve the health of their water bodies.
