The storm sewer is a system designed to carry rainfall runoff and other drainage. It is not designed to carry sewage or accept hazardous wastes. The runoff is carried in underground pipes or open ditches and discharges untreated into local streams, rivers and other surface water bodies. Storm drain inlets are typically found in curbs and low-lying outdoor areas. Some older buildings have basement floor drains that connect to the storm sewer system.
I’m updating these models from a FDM printed PLA to resin. I have found that I can actually reduce the cost by switching to resin. To that end I have cut the price for the PLA parts in half. This price may change depending on what the cost for the resin pieces come out to … I will probably make them the same.
