Question: 1 / 400

What does an urban drainage system include?

Canals and levees only

Ditches, storm sewers, retention ponds

An urban drainage system includes ditches, storm sewers, and retention ponds to manage stormwater runoff. Canals and levees may be used in larger urban areas, but are not always included in every urban drainage system. Solar-powered water pumps are not typically used in urban drainage systems as they are not able to handle large amounts of water. Elevated walkways and bridges are not considered part of an urban drainage system as they do not contribute to the management of stormwater runoff.
