Storm drains and sanitary sewers are two separate systems with one critical rule: they must not be connected. Stormwater goes to the environment, while sewage goes to treatment, and mixing them causes pollution and backups.
The storm system
Storm drains carry rainwater from roofs, streets, and yards directly to creeks and rivers, usually without treatment.
The sanitary system
The sanitary sewer carries wastewater from toilets, sinks, and drains to a treatment plant where it is cleaned.
The cross-connection
A downspout or sump pump tied into the sanitary sewer overloads it during storms, while a sewer tied into a storm drain pollutes the waterway.
The check
A dye test or a camera inspection confirms which system a pipe connects to. In Lombard, downspout disconnection programs are common.
The test
A dye test confirms which system a pipe serves before any work. Guessing wrong can send sewage into a creek or flood a basement.
