Storm Water

Stormwater is water from rain, snow, sleet, hail, that flows across the ground and pavement or when snow and ice melt. The water seeps into the ground or drains into what we call the storm drain system. These are the drains you see at street corners or the low points on the sides of streets.  When storm water runoff enters the storm drain system through the gutters outside your homes it goes, untreated, into the waters that we use for swimming, fishing, and other recreational uses.
 
Hyrum City's storm drain system consists primarily of swales, irrigation ditches, detention / retention basins, and a number of infiltration sumps. There are some curb and gutters, culverts, and a few typical piped sections. There are two main ditches and a number of springs.
