What is Stormwater Pollution?

Stormwater runoff is a leading cause of pollution in our lakes and streams and educating our citizens about the causes and effects of pollution is the best way to combat it.  Everyone can help by being aware of simple everyday choices they make.

What is stormwater?

Stormwater is rainwater and anything it carries along with it.  In Katy, when rain hits driveways, sidewalks and streets it is carried away by drainage ditches, swales and a system of pipes, eventually ending up in a river or stream.  Please do not sweep leaves or lawn clippings in the storm drains.  Unlike sewage, stormwater is not treated before being emptied into our waterways.

What causes stormwater pollution?

There are four main types of stormwater pollution:

1.         Litter, such as plastic bags and cigarette butts

2.         Chemical, such as fertilizers, pesticides and automotive fluids

3.         Organic, such as garden clippings, leaves, soil and animal droppings

4.         Thermal, such as hot water discharges from industries or pressure washing

All of the pollutants mentioned above cause problems in the rivers and streams that are the home to many aquatic organisms and provide our community with recreational opportunities.  Please do your part in keeping our environment clean, safe and healthy for people and wildlife.
