PLUMBING SYSTEM PREPARED BY

MURALI.CD.C.E & B.TECH

SANITARY SYSTEM

Sewer:

• Are the underground conduits or drains• Used for carrying the sewage• The most common types of sewer are:I. Sanitary Sewer : • Is a underground carriage system.• Used for transporting

sewage from houses and commercial buildings

•  Sanitary sewers serving industrial areas also carry Industrial sewage.

• Sanitary sewage is collected with the help of sanitary sewer line

• The sanitary sewer is attached to a main sewer.

• The main sewer runs directly to the sewage treatment plant.

II. Storm Sewer:• A storm sewer collects storm water

with the help of gutter & catch basin

• Gutter allow the storm water to drain from the street directly into the storm sewer.

Sewer:III. Combined Sewer:• Type of sewer system• Collects sanitary sewage & storm water run off in a single

pipe system.• Can cause serious water pollution problems due to combined

sewer overflows• Caused by large variations in flow between dry and wet

weather.• This type of sewer design is no longer used in building new

communities.
