dam, structure built across a stream, a river, or an estuary to retain water.
Dams are built to provide water for human consumption, for irrigating arid and semiarid lands, or for use in industrial processes..
Answer: A typical building is associated with water use in direct and indirect forms.
Direct form includes water consumed by workers, water used in washing aggregates, preparing raw concrete, curing concrete, dust suppression, and washing of hard surface and equipment..
It is found that use of recycled water in construction has been increasing
Water use is directly related to greenhouse gas emission in many cases
Concept of green buildings and zero energy buildings is becoming popular that aim to save water and energy
Water for construction can be derived from a number of sources
One of the most common sources is groundwater, which is pumped from aquifers and used for construction activities
Groundwater is mainly used for mining construction activities in remote areas, where piped water and readily available surface water are not available
Water is needed in direct construction activities and also for the production of construction materials as embodied water
Water use during life time of an infrastructure also needs to be considered in the planning and design phase of the infrastructure to save and conserve water in the long run
