Everything that you see, and a lot that you can't see laying in the gutters or on the streets is carried into the storm drains by rain or melting snow. This water and all of the pollutants that it carries flows untreated, directly into our creeks and river. The City of Casper is required by the Wyoming Department of Environmental Quality and the EPA to develop, implement, and enforce a stormwater management program, the goal of which is to protect Wyoming’s and the nation’s water quality.

• Street gutters which collect runoff
• Storm drain pipe which transports runoff
• Catch basins - inlets you see at street corners, low points of the sides of streets, or in parking lots
• Detention/retention basins that hold stormwater
• Ditches and drainage ways that further transport water to our local creeks & the North Platte River

The City of Casper storm system consists of:

• Over 529.7 miles of gutter that collects water runoff
• 75 miles of storm sewer pipe
• 3 lift stations
• 1,168 manholes
• 3,513 inlets / catch basins
• numerous ditches and drainageways
• over 200 outfalls into our six creeks and the North Platte River.
