A body of permeable rock which can contain or transmit groundwater is called aquifer. A small duct in body of fluids is called an aqueduct. The canal is an artificial tubular duct for inland waterways.

In conservancy system, compact house design is not possible, a large labour force is required and re is a spread of an epidemic. Hence, little water consumption is an advantage of conservancy system over water carriage system.

A graph showing discharge versus time at a specific point in a conduit carrying flow or river is called ?hydrograph?. Hydrograph helps in understanding flow characteristics of water at different time intervals.

Runoff can be described as a part of water cycle that flows over a land as surface water instead of being absorbed into groundwater or evaporate into atmosphere. Runoff increases water volume of surface water bodies.

Pumps are used in a variety of infrastructure systems such as supply of water to canals, drainage of low lying land, etc. Pumping stations are facilities including pumps and equipment for such activities.

Wet wear flow is higher than dry wear flow because of inflow and infiltration in sewer system. Wet wear flow is combination of stormwater and sanitary sewage but dry wear flow consists of only sanitary sewage.

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.

Yellow water refers to wastewater containing only feces. Black water is wastewater from bathrooms and toilets. Wastewater generally refers to water that cannot be used or water produced out of various uses.

Dry wear flow depends on type of area served, rate of water supply, population growth, infiltration of groundwater. Design of sewer system is to determine size of a sewer system in peak conditions. It has nothing to do with factors responsible for dry wear flow.

Conservancy system is an old system in which various types of wastes such as night soil, garbage, etc. are collected separately in vessels and deposited in pools or pits and n removed periodically once in 24 hours.
