CATCH BASINS

NDS offers a complete line of catch basins and grates for residential and commercial surface water management solutions. NDS catch basins have sump
areas that collect debris and prevent clogging of the pipeline. Grates are available in a variety of patterns and colors to blend in with surrounding surfaces.
Depending on the size of the round, square or atrium grates, they may fit directly into a riser of pipe, sewer and drain fitting, or our catch basins. To check

ROLE OF THE FILTER
Clogged pipes reduce the e ectiveness of drainage systems, resulting in standing water and damage to property. Adding a filter is a simple solution to keep
water flowing through a drainage system and a cost-e ective alternative to expensive repair or replacement.

The NDS catch basin filter is removable and cleanable, making it easy to maintain. The filter contains a bypass feature that allows water to flow to the catch
basin even if the filter is full or after a heavy storm water event. The filter comes pre-assembled, making it easy to install: unscrew the grate, drop in the
filter and reinstall the grate. The filter bag is made out of nonwoven, spun-bonded, polypropylene geotextile fabric that provides superior filtration, is inert to
biological degradation and is resistant to naturally encountered chemicals, alkalis and acids. The bag can hold up to 18 kg without tearing and is UV resistant.
