A Solution to the Global Water Crisis Desalination A Solution to the Global Water Crisis Michael Stanley, Joshua Cole, Connor Martin, Connor Horan, Ryan Halper, Matthew Stein Oakley

Introduction Nearly 70% of earth is made up of water, yet only 2.5% of that is freshwater and only 1% of freshwater is easily accessible to humans Water use has grown at twice the rate our population has grown 844 million people live without access $260 billion lost globally every year What is the solution? Water use: according to the united nations According to water.org 844 mil ppl: to safe water, which is about 1 in every 9 people 260 billion: lost globally because of lack of basic water and sanitation (water.org)

Introduction Potential solution: Desalination Taking seawater and turning it into freshwater Many ways to do this However, extremely expensive and uses fossil fuels So the question becomes, how do we make desalination cheaper and more environmentally friendly? Joshua Explain briefly reverse osmosis

Communities in Need South Africa: Cape Town overpopulation “Day Zero” concept due to lack of rain water Migration from the Eastern Cape since 2000 → 1 million people increased to 4 million Lowest rainfall between Jan - Dec 2015 since national recordings began in 1904 Potential expansion to deprived countries/islands bordering oceans

Reaching the Final Design Looking to Waves Our team analyzed many different wave technologies that could potentially be utilized. Given the cost and complexity of larger scale systems, we came to believe that a design proposed by U.S. based firm Atmocean would be the most viable and cost-effective solution for the scope of our project.

Reaching the Final Design The Wave Rider Array Atmocean is an ocean wave energy company. Using an array of offshore buoy pumps, pressurized seawater can be sent ashore and processed through a reverse osmosis system to produce clean water.

Monitoring and Stakeholders Involved Basecamp or other project management software For transparency between stakeholders and partners Monthly Stakeholder Meetings Monthly meetings will be open and an expectation for team leaders of the stakeholders and partners will include: Progress Reports Financials Expansion Plans Action Plan Debriefing on success of last months Action Plan Concerns, Open Q&A, and Comments

Resources $1 Million dollar conservative estimated cost of install ~$300,000 in yearly operating costs $1.16 - 1.32 per cubic meter of water Zero energy input reduces costs by about 44% Scaling up with added arrays would further reduce cost Much less expensive than other renewable desalination methods

The Difference Cape Town uses approximately 500,000 cubic meters of water a day Our system produces approximately 615 cubic meters a day Scaled up to 10 arrays, we could produce approximately 1% of Cape Towns daily water needs - or water for about 40,000 people Conservative production estimate for 10 arrays is 10 million dollars Potential for agriculture and aquaculture applications South Africa has been cutting agricultural water allowances to compensate Virtually no emissions from operations
