rainwater-retention = local rainwater holding to releive the public sewer system


    The retention of surface water in urban areas - especially in new construction areas - is becoming more and more important, both in private and in public areas. Numerous municipalities collect taxes for sealed surfaces and prescribe the retention of rainwater, in some cases it is also supported.

    The retention tank / system collects up the accumulated rainfall, stores it and delivers it to the sewer system with a time delay / throttling. So the channel can be relieved during heavy rainfall events.

      GreenLife offers a large assortment for a wide variety of applications:

      • • retention tanks of 2.000 l – 6.500 l
      • • with floating flow regulators with flow rates between 0,05 – 2,5 l/s
      • • with calmed inlet and overflow siphon
      • • optionally - combination of retention and rainwater harvesting
      • • easier handling in comparisaon to concrete or steel tanks
      • • with infinitely extendable sliding dome ( 300 mm – 430 mm) and 5° inclinable for optimum terrain adaptation
      • • optionally - accessible by cars*
