But the company knew its large, concrete system would be far too costly and cumbersome for the low-flow (1 to 5 cfs) stormwater market. To get something more light weight the company worked with the plastics design and manufacturing firm Meese Orbitron Dunne Co.
MOD engineers designed a rotationally molded alternative using advanced 3D modeling that eliminates a weighty concrete vault, concrete cover, and stainless steel doors. The compact housing for the Trashmaster Net Capture System is a single rotationally molded part made from durable high-density polyethylene (HDPE), with a manhole cover for access. The housing costs as much as 50% less to produce, is just a quarter the weight (the rotomolded part with the stainless steel innards weighs 750 lb versus 3,000+ lb for its concrete counterpart), and installs in a day using on-site equipment compared to a week for its concrete counterpart. The plastic part fits pipe up to 24 in. in diameter and can be installed to a depth up to 10 ft.
