Unicomm Parking Lot Drainage, Bassano del Grappa, Italy

The project required stormwater drainage, detention, and infiltration in the car park of a new shopping center. The total catching surface was 4,200 m2 and the total water volume to be managed was 1,450 m3

Drening, our plastic tunnel for rainwater infiltration and attenuation, was installed in long lines with intermediate inspection manholes. This allowed to drastically reduce installation time while improving drainage capacity.
