Climate Change and Water Scarcity

ball-1055956_640At the Paris World Climate Summit held in December 2015, participants overwhelmingly agreed to work on a legally binding agreement to reduce carbon output as soon as possible. While currently non-binding, there is commitment to “do their best to reduce their carbon output”.  Global warming is expected to account for approximately 20% increase in water scarcity this century.

According to the Natural Resources Defense Council (NRDC), “Climate change will have significant impact on the sustainability of water supplies in the coming decades.”

The Federal Clean Water Needs Survey identified over $100 billion in needed infrastructure in the next 20 years to address stormwater and sewage overflows.

The NRDC goes on to explain that capturing rainwater from rooftops is an effective water resource management strategy that increases supply and reduces pollution.

The unnecessary use of potable water for non-potable uses, such as outdoor landscape irrigation and indoor toilet flushing, climate change and continually increasing areas of impervious surfaces in our landscape, results in stormwater runoff carrying pollution to our rivers, lakes, and beaches. Although the problems of water supply and water pollution can be complex, practical solutions for both are available now, such as capturing and using rainwater from rooftops.

Rooftop rainwater capture is a simple, cost-effective approach for supplying water that promotes sustainable water management. Reusing rainwater, rather than allowing it to run off of paved surfaces to pick up pollutants and carry them to nearby surface waters, is a practice which provides numerous benefits:

  • Inexpensive, on-site supply of water that can be used for outdoor non-potable uses with little, if any, treatment, or for a variety of additional uses including potable supply with appropriately higher levels of treatment
  • Reduced (or no) energy and economic costs associated with treating and delivering potable water to end users because capture systems often use low-volume, non-pressurized, gravity fed systems or require only the use of a low power pump for supply
  • Reduced strain on existing water supply sources
  • Reduced runoff that would otherwise contribute to stormwater flows, a leading cause of surface water pollution and urban flooding.

Drought, Water, Health and Life

flower-887443_640We at RainBank firmly hold true the belief that access to clean water is a basic human health necessity and a deserved right for all people.

The effects of climate change threaten our supplies of this resource that we simply cannot live without. According to the NDRC (National Resources Defense Council), nearly every U.S. region is facing some increased risk of seasonal drought.

The NDRC also reports “climate change will significantly affect the sustainability of water supplies in the coming decades. As parts of the country get drier, the amount of water available and its quality will likely decrease – impacting people’s health and food supplies.”

According to its website, the NRDC is a U.S. environmental action group, combining the grassroots power of more than 2 million members and online activists with the courtroom clout and expertise of nearly 500 lawyers, scientists and other professionals.

The article Drought: Threats to Water and Food Security discusses how public health will be compromised if access to clean water isn’t always available. Many states including California, New York, Maryland, New Hampshire, Oregon, Pennsylvania, Washington, Wisconsin and Virginia have developed drought plans.

The Untapped Savings In California’s Water Supply offers suggestions on ways to conserve water through rainwater harvesting, water reuse, energy efficient appliances and drought resistant landscaping.

We can all do our part to conserve and preserve water – our lives on this planet depend on it!

Would You Drink Poop Water?

From Poop to Potable

Bill Gates challenged a group of engineers to come up with an affordable way to get rid of disease-spreading sewage in developing countries where getting rid of waste is too costly.  The engineers rose to the occasion and developed a process called Omniprocessor, which makes drinking water from sewage.

Gates saysThe water tasted as good as any I’ve had out of a bottle. And having studied the engineering behind it, I would happily drink it every day. It’s that safe.”

Watch as Bill Gates gets Jimmy Fallon to drink water made from poop.
