What is Storm Water? Storm water is the result of precipitation.  Rain, sleet, and hail all contribute to the formation of storm water.  The water that does not seep into the ground is collected by the storm sewer system is order to prevent flooding and standing water which can create many other problems.  The storm sewer system is has many outlets and not all water ends up in the same place.  Some storm water is collected in dry wells where the water will seep back into the ground.  Other storm water is collected in grassy storm basins and allowed to seep back into the ground.  The rest of the storm water is channeled to the Stanislaus River. 

What about Pollution? It is important to know that the water that enters the storm sewer system is not treated at all before entering the ground or the River.  Preventing the introduction of pollutants into this system helps ensure the safety of our drinking water, of our children playing in storm basins, and the fish and other wildlife that live in and around the Stanislaus River.  There are many types of pollution that are easily contained before they become a problem.  Some of these are: 

1. Pet waste
2. Vehicle fluids 
3. Old paint, solvents, batteries, and other chemicals
4. Debris and surface dirt
5. Yard waste

Construction debris.  When using concrete or other building materials, do not wash out into the street.  This concrete can plug up the storm sewer system causing flooding as well as other problems.
