I am sure by now many of you are aware of the major water crisis facing Cape Town, South Africa, as a result of dwindling water levels in their reservoirs and an increase in water demand. The article below by Lucas Joel, provides further details on the issue.
With technology being a big part of our day to day lives it’s seems inevitable that it can be used to solve issues of water usage and improve efficiency. This is highlighted in an article by Lori Lovely in the June 2017 issue of the Water Efficiency magazine.
Water Demand Management
Using technology to forecast water usage and improve efficiency
by Lori Lovely May 25, 2017
Mni wiconi is Lakota for “water is life.” The phrase articulates a fundamental truth. Our lives depend on water. Planning to meet and manage demand is essential.
Demand for water has risen relentlessly over the years as the world’s population climbs past the 7 billion mark, with projections of continued growth. Lifestyle affects demand as climate change affects supply.
While demand is easily understood, responding to it involves a complicated set of choices. It can be met with a supply-side response—developing new resources—or a demand-side response—management by influencing demand and water use through more efficient use of water that is already available in order to meet objectives such as economic efficiency, environmental protection, sustainability, or other reasons that could include social equity.

With the present restrictions placed on the public’s use of water hoses and power washers, in terms of watering their private gardens and washing their vehicles, there has been an outcry by many persons about increased water rates (although lower rates are subsidized for customers without meters, which can be noted in the State of the Water Resources Report, 2005, which also provides a listing of the various water tariffs), as well as, the fact that there is a desalination plant to provide additional water supply.
Having recently read an article in the Water Efficiency Magazine entitled Parched: Can desalination quench the world’s thirst? by Laura Sanchez I immediately thought about such comments from the public.
This article highlighted the early history of desalination in the United States in 1970 and its possibility of solving a myriad of problems, as well as, pointed out various present issues with desalination such as its expense, the fact that it is energy-intensive and the argument of environmental impacts to marine resources and the large amounts of seawater being depleted.
Such points can lead to one really wondering how sustainable is the process of desalination. I would be curious to hear the pros/cons from employees since I know we have both environmentalists and water resources practitioners on board.
