Water Efficiency Measures
Published in Eric A. Woodroof, Green Facilities Handbook, 2020
The 20 water conservation measures identified in this chapter have been broken down into four types of uses. Interior water use is defined for purposes of this chapter as use in plumbing fixtures located in existing business structures.Landscape use includes all water used for landscape irrigation and the measures to increase efficiency are presented in two categories: landscape design, and landscape installation and maintenance.Pools and fountains include swimming pools, spas, decorative pools, and fountains.Process use includes any water used in facility cooling or for manufacturing processes.
Water management and technology

With the Romans also came fountains, pools, and ornamental water features. Fountains, while also ornamental, also provided a supply of water to those who could not afford to connect public water pipes to their homes. Communal fountains allowed a person to bring their vessel to the basin and fill it. These functioned much like perennial springs, rivers, or public wells where people collected daily water.
Water Management

Floating fountains (also called display fountains). These electrically charged floating devices with a motor or pump/motor send jets or fountains of water into the atmosphere, which dissolve O2 and, through wave action following surface impact, support aerobic bacteria (Figure 8.38). Although spectacular, fountains normally do not move the volume of water that true aerators do.
Hypolimnetic oxygenation 4. Effects on turbidity in Camanche Reservoir and its downstream fish hatchery
Published in Lake and Reservoir Management, 2020
Prior to vigorous aeration before the hatchery, the deep-water inflow water was only slightly cloudy, and the hatchery tray samples a little more so. The main aeration system for the hatchery in the late 1980s to mid 1990s consisted of a very large wooden tank into which the reservoir bottom water flowed. The hydraulic head from the deep hypolimnion supply created a 10 m high fountain that splashed back into to the tank. The DO after this vigorous aeration was at saturation, even when DO in the supply from the reservoir was very low. This system was removed a few years after HOS installation and the feed to the eggs was routed via sand filters. In contrast. most of the inflow to the raceways and holding tanks is not sand filtered. Although sand filtration probably benefited the hatchery eggs, its installation did not occur until at least 1998, well after the work reported here. In addition, river-spawned fish increased along with hatchery-spawned ones following HOS (Horne 2019), but the river water volume was too large to ever be sand filtered.

In this article, we dealt with some diagnostic analysis carried out on the Fontana di Trevi in Rome (Italy), which is one of the most famous monuments in the world. It is a fountain fed by the aqua Virgo, the only one Roman aqueduct still in service. The whole structure is set against the façade of Palazzo Poli. The monument was built between 1732 and 1762 by the Roman architect Nicola Salvi (V.V.A.A. Fontana di Trevi. La Storia, Il Restauro, ed 1991). The whole monument has three architectural elements: a façade made mainly of travertine; statues and relieves made of marble; a cliff made of travertine and mortars (Laurenzi Tabasso 1991; Rockwell 1991). The fountain, shaped like a triumphal arch with a deep central dome, slopes down to the broad basin with a large cliff, enlivened by sculptural representation of many plants and the spectacular water slide. The composition is dominated by the colossal statue of Oceanus, the personification of natural forces, which appears on a shell-shaped chariot pulled by two horses led by tritons, symbolizing the two natural realities: the wild (the angry horse) and ordered (the placid horse). In the left part of the arch, there is the statue of Abundance holding the horn of plenty. Above her there is a bas-relief showing Agrippa commanding his generals to build the aqueduct. On the right side, there is the statue of Health and above her, there is a relief showing a Virgin Lady indicating the source of water. A previous restoration work (1989–1991) has been well documented (V.V.A.A. Fontana di Trevi. La Storia, Il Restauro, ed 1991), while for former interventions information are quite scarce.

The site map is useful, as it shows the real-time water quality of each element (e.g., drinking fountain, intake, or distribution network) on the campus. When the water quality of an element complies with the Mexican national water regulations, it is depicted in green; if not, it is depicted in yellow. A pie graph showing the percentage of total data complying with Mexican water quality regulations is shown in Figure 15. This screen shows the drinking devices whose water complies with regulations, i.e., tap water (green dots), and whose water is not to be consumed until advised due to bacterial contamination (yellow dots). The pie chart shows the percentage of compliance (100% green).
