Key to effective and efficient water pricing is a systematic process to understand: (i) the value of water in alternative uses; (ii) the private and external costs of supplying water services; and (iii) the multiple options to determine an appropriate water tariff. Within the four dimensions of water pricing (uniform versus variable tariff and ...
As of 2017, the New Orleans pumping system - operated by the Sewerage and Water Board - can pump water out of the city at a rate of more than 45,000 cubic feet (1,300 m 3) per second. [ 1 ] [ 2 ] The capacity is also frequently described as 1 inch (2.5 cm) in the first hour of rainfall followed by 0.5 inches (1.3 cm) per hour afterward. [ 2 ]

Canal lining is the process of reducing seepage loss of irrigation water by adding an impermeable layer to the edges of the trench. Seepage can result in losses of 30 to 50 percent of irrigation water from canals, so adding lining can make irrigation systems more efficient. Canal linings are also used to prevent weed growth, which can spread ...
Water distribution network is the term for the portion of a water distribution system up to the service points of bulk water consumers or demand nodes where many consumers are lumped together. [5] The World Health Organization (WHO) uses the term water transmission system for a network of pipes, generally in a tree-like structure, that is used ...
Drainage. High-density polyethylene pipe installation in a storm drain project, Mexico. Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many ...
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
