The United Nations estimates that the global demand for water will increase 20% to 30% by 2050 to meet the food needs of a projected population of 9.8 billion.

A little water conservation can go a long way.

And as the second-most visited space in commercial buildings — just behind the lobby — the restroom and its water-saving fixtures can help lead the way when it comes to cutting back consumption.

Although evaporative cooling is great at saving energy, it does consume some water, but the benefits on energy savings outweigh the water usage, which in some places is a scarce resource.

Delaware is experiencing dry conditions with an open burning ban in effect.

Dishwashing is responsible for over half of tap water used in the kitchen, according to the results of a new study, which also suggest that people who live alone consume double the water per person that those that live in a four or five-person household. Although relatively few households were studied, this research could prove useful in helping develop consumer advice for saving water.

The EveryDrop LA app makes it easier for ordinary Los Angelenos to identify and report sources of wasted water in their communities.
