O Scale 1:48
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.
This is an O scale (1:48) model of one part of this system – an Offset Cove. The base sits at the bottom with sewer pipes entering the bottom of the casing. The Cover Riser locks to the top of a base with standoffs to support the Cover (which has an opening for a Manhole ring and Manhole)
