SABUG Throttle Manhole DN 400

System manhole for fixed throttling of rainwater.

Favored by climate change, heavy rainfall events continue to increase from year to year. Cities and municipalities are increasingly finding that the pipe cross-sections calculated years ago for stormwater pipes have long been inadequate. For this reason, it makes sense to limit the inflow of rainwater in new buildings.
