savunpoistojärjestelmät

I’m not sure what term you intended. “Savunpoistojär...” appears truncated and I can’t identify a real place or concept by that spelling. Could you provide the full term or a bit more context (for example, is it a Finnish place name, a geological feature, or a concept in environmental engineering or fiction)?

If you’d like, I can also create a concise, neutral wiki-style stub for a fictional term with that root meaning, such as “Savunpoistojärvi” (imagined as a lake associated with smoke removal or filtration), including sections on name origin, geography, ecological significance, history, and use. Please confirm which you prefer.
