As per many authentic references, about 97 percent of the water in the world belongs to oceans and seas, whereas 3 percent is freshwater available as glaciers, ice caps, and waterbodies. While we strive to manage available lakes, rivers, and other inland water resources to meet present and future public needs, why not look to these saline water reservoirs as potential alternatives for sustainability?

In the recent decades, the market for the products of the industrial process industries has changed greatly. The manufacture of mass products has shifted to locations where raw materials are available economically. Competitive pressures have forced a swing to specialization as well as to an ability to adapt to customers desires. The systems are designed so that the economic data, such as raw material properties, raw material costs, batch sizes, are quickly integrated into the processes. An important consideration is the assurance and improvement of product quality.

The past few months have been highly eventful for California water watchers. In June, by a margin of 57 to 43 percent, California voters approved Proposition 68, a $4.1 billion parks and water bond that will provide approximately $1.3 billion for water-related projects across the state. Then in July, the California Water Commission approved $2.6 billion of funds authorized by Proposition 1, passed by the voters in 2014, to be used for eight new water storage projects. These developments reflect that California is taking a bold and multi-pronged approach to addressing its water needs, investing both in new large infrastructure projects and in more modest projects to improve the state’s existing resources and assets.
