The city determined that it needed a third water tunnel so that Tunnels 1 and 2 could be closed for inspection and repairs. Stage One construction of Tunnel 3 began in 1970 and completed in 1993. This portion was put into service in 1998 and cost about $1 billion. [3] [7]
Within this choice set, the preferred water tariff depends on multiple factors including: the goals of water pricing; the capacity of a water services supplier to allocate its costs, to price water, and to collect revenues from its customers; the price responsiveness of water consumers; and what is considered to be a fair or just water tariff.

Desalination, which produces usable water from saline water, has a higher LCW than processing groundwater or surface water. A 2020 study found that advances in decarbonization would reduce the levelized cost of water produced via desalination from €2.4 per cubic meter in 2015 (US$2.84) to €1.05 per cubic meter in 2050 (US$1.24).

The water system has a storage capacity of 550 billion US gal (2.1 billion m 3) and provides over 1.2 billion US gal (4.5 million m 3) per day of drinking water to more than eight million city residents, and another one million users in four upstate counties bordering on the system.
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.
The parking garage at the corner of Water and Henry streets will replace a 52-old-year parking garage the city demolished in 2022 after years of structural concerns.
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 ]
The sustainable water supply system is an integrated system including water intake, water utilization, wastewater discharge and treatment and water environmental protection. It requires reducing freshwater and groundwater usage in all sectors of consumption.
