8. WASTE WATER COLLECTION SYSTEM DIFINITIONS
Sewer: Sewers are under ground pipes or conduits which carry sewage to points of disposal.
Sewage: The Liquid waste from a community is called sewage. Sewage is classified into domestic and non-domestic sewage. The non domestic sewage is classified into industrial, commercial, institutional and any other sewage that is not domestic.
Sewerage: The entire system used for collection, treatment and disposal of Liquid waste. This includes pipes, manholes, and all structures used for the above mentioned purposes.
Infiltration: It is the water which inters the sewers from ground water through Leaks from loose joints or cracks.
Inflow: It is the water which inters the sewers from the manholes during rainfall events.

Under ground Sewer

10. Type of wastewater from household
Source of wastewater
Gray water
Washing water from the kitchen, bathroom, laundry (without faces and urine)
Black water
Water from flush toilet (faces and urine with flush water)
Yellow water
Urine from separated toilets and urinals
Brown water
Black water without urine or yellow water

13. Generally, most of the countries recently preferring separate systems.
Types of collection systems
Separate system
Sanitary system
Combined system
Both sanitary & storm water
Storm water
1. Used for domestic and industrial wastes in addition to inflow and infiltration. Storm water is not considered.
2. It is preferred for the following:
The size of pipes is much smaller than the combined system sewers. This gives the advantage of good hydraulics in the pipe (the pipe is Designed to have a minimum velocity to prevent sedimentation of sand)
Separation of wastewater from storm water minimize the total quantity of sewage which has the following advantages :
1. Smaller pumping stations are needed.
2. Smaller and more efficient treatment plants are needed.
3. Overflow of combined sewers in the storm events produces pollution to environment which is not the case in separate sewer.
Only unavoidable Storm water inters the system which protects the system from the accumulation of sand in the sewers in the non-paved areas.
It is used for both storm water and wastewater.
It is preferred for the following cases:
For areas of long rainy seasons.
For areas where it is difficult to construct two pipelines in the streets crowded with other services (electricity, telephone, gas, etc...).
It’s not preferred for areas of short rainy season, and for areas poorly paved which leads to the accumulation of sand in the system.
Combined system is 40% lower in cost than separate system.
Generally, most of the countries recently preferring separate systems.
