==Inflow==
Water entering sanitary sewers from inappropriate connections is called ''inflow''.<ref name="king"/> Typical sources include sump pumps, roof drains, cellar drains, and yard drains where urban features prevent surface runoff, and storm drains are not conveniently accessible or identifiable. Inflow tends to peak during precipitation events, and causes greater flow variation than infiltration. Sources of inflow can sometimes be identified by [[smoke testing]]. Smoke is blown into the sewer during dry weather while observers watch for smoke emerging from yards, cellars, or roof gutters.<ref name="hammer">Hammer, Mark J.
