Water dispenser. A water dispenser, sometimes referred to as a water cooler (if used for cooling only), is a machine that dispenses and often also cools or heats up water with a refrigeration unit. It is commonly located near the restroom due to closer access to plumbing. A drain line is also provided from the water cooler into the sewer system.
Drinking water supply and sanitation in Pakistan is characterized by some achievements and many challenges. [citation needed] In 2020, 68% Pakistanis, 72% Indians, 54% Bangladeshi had access to the basic sanitation facilities. [9] Despite high population growth the country has increased the share of the population with access to an improved ...
Drinking water supply and sanitation in Egypt directly impact the country's public health, industrial developments, and agriculture. Egypt's water and sanitation industry is characterized by both achievements and challenges. Among the achievements are an increase of piped water supply between 1998 and 2006 from 89% to 100% in urban areas and ...

A shadoof or shaduf[1] is an irrigation tool that is used to lift water from a water source onto land or into another waterway or basin. It is highly efficient, and has been known since 3000 BCE. [citation needed] The mechanism of a shadoof comprises a long counterbalanced pole on a pivot, with a bucket attached to the end of it.
Water resources management in modern Egypt is a complex process that involves multiple stakeholders who use water for irrigation, municipal and industrial water supply, hydropower generation and navigation. In addition, the waters of the Nile support aquatic ecosystems that are threatened by abstraction and pollution.
Egypt's climate is hot, dry, and dominated by desert. Egypt has a hot summer from May to October and a mild winter from November to April.

Heavy water is less dissociated than light water at given temperature, and the true concentration of D + ions is less than H + ions would be for light water at the same temperature. The same is true of OD − vs. OH − ions. For heavy water Kw D 2 O (25.0 °C) = 1.35 × 10 −15, and [D + ] must equal [OD − ] for neutral water
