QUIZ 100 Flashcards
Water and its appropriate use are becoming an important part of design, especially the design of green buildings
BASICS OF WATER SUPPLY
Every building designed today is supplied with potable water
BASICS OF WATER SUPPLY
Most of this clean water is used to carry away organic waste
BASICS OF WATER SUPPLY
Results in a wide range of design impacts affecting detailed bathroom fixtures arrangement, and the overall plans of large and complex water and sewage treatment facilities
BASICS OF WATER SUPPLY
it needs to deliver adequate amounts of water to meet consumer consumption requirements plus needed fire flow requirements
REQUIREMENTS OF A WATER SYSTEM
the water system needs to be reliable; the required amount of water needs to be available 24 hours a day, 365 days a year.
REQUIREMENTS OF A WATER SYSTEM
Lakes, reservoirs, rivers
Surface Water
Rivers dammed to create reservoirs
Surface Water
Reservoirs store water during heavy rain/snow
Surface Water
Primary source of drinking water
Aquifers (Groundwater)
Porous consolidated rock or unconsolidated soil
Aquifers (Groundwater)
Groundwater fills spaces
Aquifers (Groundwater)
Wells and pumps used to extract water
Aquifers (Groundwater)
Well construction typically consists of three steps. What is the 1st step?
A well will be drilled to meet all well construction standards in the area
Well construction typically consists of three steps. What is the 2nd step?
A trench is dug to connect the well to the system
Well construction typically consists of three steps. What is the 3rd step?
A well pump is selected that will raise water from the well and deliver it to a water treatment plant, then to a storage tank where it is held under pressure until needed
What are the different types of wells that are used as sources of water?
- Bored Wells
- Driven Wells
- Jetted Wells
- Drilled Wells
A well that is dug with earth augers, usually less than 30 meters deep
Bored Well
A well that is located in boulder-free sites that will not cave in
Bored Well
A well with a diameter range of 50mm (2”) to 760mm (30”)
Bored Well
A well that is cased with metal, vitrified tile, or concrete.
Bored Well
The simplest and usually the least expensive type of well
Driven Well
A steel drive-well point (32-50mm dia.) is fitted on the end of the pipe sections and driven into the earth (well type)
Driven Well
A pilot hole is dug first, and the drive-well point and pipe sections are lowered into it (well type)
Driven Well
Well is driven well below the water table (well type)
Driven Well
A well that requires a source of water and a pressure pump
Jetted Wells
A washing well point is supplied with water under pressure ; this loosens the earth and allows the point and pipe to penetrate (well type)
Jetted Wells
A well that requires elaborate equipment of several types
Drilled Wells
