As a result, Congress authorized SELA to improve flood control and rainfall drainage systems in Jefferson, Orleans, and St. Tammany Parishes. The authorization was contained in Section 108 of the Energy and Water Development Appropriations Act for Fiscal Year 1996 and Section 533 of the Water Resources Development Act (WRDA) of 1996.
Concordia Parish, Louisiana is in the foreground, on the right, and Wilkinson County, Mississippi, is in the background, across the Mississippi on the left. Old River low-sill control structure discharging water into the Atchafalaya, May 2011. The Old River Control Structure is a floodgate system in a branch of the Mississippi River in central ...
Because certain combinations of check valve failure and/or system backpressure cause the relief valve to discharge, the device must be mounted in a location where the drain will not become flooded. An example of where backflow would harm the water supply is the use of well washing devices inside underground sewerage pumping stations.
The floodwall starts north of the pump station and gate structure with a water control structure across the Old Estelle Outfall Canal, and extends southward along the eastern edge of the Bayou aux Carpes 404(c) area. A canal closure wall connects the floodwall and navigable floodgate on the GIWW.

Water supply networks are often run by public utilities of the water industry.

The source and sink composite curves is a graphical tool for setting water recovery targets as well as for design of water recovery networks. [5] A 2018 study found by water pinch and water footprint analysis that for bricks with typical materials of clay and shale, the water consumption footprint was 2.02 L of water per brick. [6]
An example of a water distribution system: a pumping station, a water tower, water mains, fire hydrants, and service lines [1] [2]. A water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements.
