Storm Water Program
The goal of the City’s Storm Water Program is to prevent pollution from reaching our waterways or the New River. Only rain down our drain!
The City of Calexico works to prevent storm water pollution under regulation of the Colorado River Basin Regional Water Quality Control Board. The California Regional Boards adopted new storm water regulations to further protect rivers, creeks, lakes, and other water bodies. A copy of the regulations can be found at Phase II Small MS4 General Permit Order No. 2013-0001 DWQ, which are effective July 1, 2013.
Due to our desert climate, many residents within the City of Calexico are unaware of the storm drain pollution threatens our local 
, the New River, the Salton Sea, and ultimately our environment. In fact, many people don’t realize that much of the City’s storm drains connect directly to streams and rivers, which can cause pollution when oils, grease, litter, pesticides, fertilizers and animal wastes pass through our storm drain system.
Storm Drain versus Sanitary Sewer Systems
Storm drain and sanitary sewer systems serve different purposes and it is very important to protecting wildlife and the environment for people to understand the difference.
Catch basins are the entrance into the Storm Drain System and are typically located at the bottom of a hill, at street corners, or in parking lots. The storm drain system collects and transports rain water and other liquids away from these areas through underground pipes and out to streams and rivers such as the New River. The Storm Drain System does not remove pollutants from the water before it is discharged into the river.
The Sanitary Sewer System collects wastewater from sinks, toilets, washing machines, and floor drains where it is transported through underground pipes to a wastewater treatment plant. The wastewater treatment plant removes many pollutants from the water before it is discharged back into the river.
Improper disposal of wastes is very harmful to the environment, hazardous to public health, and violates state and federal law. 
materials from homes and businesses include paint, pesticides, fertilizers, lawn and garden clippings, animal waste, cleaners and many more. Even water-soluble cleaning products contain chemicals that are harmful to aquatic life and drinking supplies.
