Where does Stormwater go?
Because excess stormwater can increase the potential for flooding and property damage, it is collected into a drainage system. Storm sewer systems collect stormwater runoff and carry it away from roads and buildings to a discharge point, often into a stream or river.
Where does water runoff go once it enters a storm drain in San Diego?
The sanitary sewer system drains to a treatment plant. The storm sewer (or storm drain) system does not. Everything that goes into storm drains goes out to Paradise Creek, the Sweetwater River, San Diego Bay, and other local waterways without any treatment.
Who owns storm drains?
Generally speaking, you’re usually responsible for drains inside the boundaries of your property, while the sewerage company is responsible for lateral drains, which are usually outside of property boundaries, and sewers.
Why is stormwater bad?
Why is stormwater pollution so bad? As polluted water makes its way to the oceans, water quality can be affected, which often results in the closing of local beaches due to unhealthy water conditions. Stormwater carries disease-causing bacteria and viruses. Swimming in polluted waters can make you sick.
Can rain water go into sewer?
Surface water drainage occurs when rainwater falls on a property and drains away. Most rainwater falling on properties drains into public sewers owned by the ten water and sewerage companies in England and Wales. Surface water drainage occurs when rainwater from your property drains into the sewer.
What can go down stormwater drain?
Chemical storage. The drain is just for water – chemicals, oils, paints and litter don’t belong there. Do not allow anything other than clean rainwater to enter the stormwater drain on or near your premises.
What are street drains called?
A storm drain, storm sewer (United Kingdom, U.S. and Canada), surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved streets, car parks, parking lots, footpaths, sidewalks, and
What cities does rainwater go?
In urban areas, though, when it rains, it pours! City streets, rooftops and parking lots make for hard surfaces that convert huge amounts of rainwater directly into runoff. In a typical city block, stormwater is collected by drains and catchbasins which then convey it underground through sewers.
How deep is a storm drain?

How does stormwater affect human health?
Stormwater runoff that carries pollution can also affect human health. Many carcinogens, such as heavy metals that can have toxic effects on humans, are among the pollutants found in stormwater runoff. The contaminated water, carrying pathogens and harmful bacteria, can also be a source of water-borne illness.
What chemicals are in stormwater?
Many toxic chemicals, such as pesticides and herbicides are found in stormwater, along with oil, grease, and heavy metal(loid)s such as Cd, Cr, Cu, Ni, Pb, and Zn (Wong et al., 2000). Nutrients such as N and P are also important pollutants in stormwater.
What is the impact of stormwater?
Uncontrolled stormwater runoff has many cumulative impacts on humans and the environment including: Flooding – Damage to public and private property. Eroded Streambanks – Sediment clogs waterways, fills lakes, reservoirs, kills fish and aquatic animals. Widened Stream Channels – Loss of valuable property.
