This set of Waste Water Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Classification of Water Carriage System”.
1. Water carriage is the conducting or conveyance of water from place to place.
a) True
b) False
View Answer
Explanation: Transportation or conveyance by water is called water carriage. One of the advantages of water carriage is that it makes it possible for the combining of latrines and bathrooms together as water closets.
2. Water supply system is a system of hydraulic and hydrologic components which provides water supply.
a) True
b) False
View Answer
Explanation: A network or system which provides water using hydraulic and hydrologic components is called water supply system or water carriage system. Hydrologic components are used to measure various parameters such as depth of flow, flow velocity, etc.
3. The area of land where all the precipitation falls will flow downhill into a specific stream called _______
a) Reservoirs
b) Water tanks
c) Water towers
d) Drainage basin
View Answer
Explanation: The water that falls on the ground and flows across the surface until it hits a stream is called runoff. Each waterway has a drainage basin, which is an area of land where all precipitation that falls will flow downhill into a specific stream.
4. What is the drainage basin also called as?
a) Watershed
b) Runoff area
c) Water pond
d) Wetland
View Answer
Explanation: Each waterway has a drainage basin which is an area of land where all the precipitation that falls will flow downhill into a specific stream and it is also called watershed. Watershed management is the process of creating and implementing programs, plans and projects to sustain and enhance watershed functions that affect the plant, animal and human communities within a watershed boundary.
5. The part of the precipitation, snowmelt or irrigation water that appears in uncontrolled surface streams is generally called as _______
a) Sewers
b) Drains
c) Runoff
d) Rivers
View Answer
Explanation: Runoff can be described as a part of the water cycle that flows over a land as the surface water instead of being absorbed into groundwater or evaporate into the atmosphere. Runoff increases the water volume of surface water bodies.
6. What is the body of permeable rock which can contain or transmit groundwater called?
a) Bore well
b) Aquifer
c) Canal
d) Water table
View Answer
Explanation: An aquifer is an underground layer of water-bearing permeable rock, rock features or unconsolidated material from which groundwater can be extracted using a water well.
7. The water supply consists of a connection point from where the fire fighters can tap water and is called as _______
a) Fire hydrant
b) Fire point
c) Water towers
d) Ditches
View Answer
Explanation: A fire hydrant also called as a fire plug is a connection point by which fire fighters can tap water from a water supply. It is a component of active fire protection. It helps in emergency situations and rescues.
8. ______ is used to lift surface water and move it to a nearby treatment plant.
a) Water carriers
b) Pumps
c) Low-lift pumps
d) Water suppliers
View Answer
Explanation: Many kinds of pumps are used in the distribution system. Pumps that lift surface water and move it to a nearby treatment plant are called low-lift pumps. Pumps that discharge treated water into arterial mains are called high-lift pumps.
9. What are the facilities including pumps and equipment for pumping fluids from one place to another are called?
a) Pumpers
b) Pumping area
c) Pumping facilities
d) Pumping stations
View Answer
Explanation: Pumps are used in a variety of infrastructure systems such as the supply of water to canals, the drainage of low lying land, etc. Pumping stations are facilities including pumps and equipment for such activities.
10. What is an artificial channel for conveying water, typically in the form of a bridge across a valley or other gap called?
a) Aquifer
b) Canals
c) Aqueduct
d) Tunnel
View Answer
Explanation: A body of permeable rock which can contain or transmit groundwater is called aquifer. A small duct in the body of fluids is called an aqueduct. The canal is an artificial tubular duct for the inland waterways.
