  • All connections DN 100.
  • Height difference of 117 mm between rainwater inlet and wastewater outlet.

How it works

SPEL zisternen filter how it works
  • Rainwater is led onto the first filtration step.
  • Coarse and larger dirt particles are led away to the sewer.
  • The pre-filtered rainwater, having passed the primary filter, reaches the second and finer filter. From here finer dirt passes to waste, clean water to the tank.
  • The cleaned rainwater is led through a calmed flow inlet into the rainwater tank.
  • Due to the steep inclination of the fine filter and its smooth surface structure the dirt is quickly cleaned away into the sewer.
