Wastewater as a Resource Leaders Forum, 15 November 2017

As part of the IWA Water and Development Congress & Exhibition in Buenos Aires, there will be a special, invitation-only,  Leadership Forum on wastewater reuse:

Wastewater Management and Reuse to build Water Wise Cities: Innovative Solutions for Engagement, Planning and Investment, 15 November 2017

Co-organised with World Bank, CAF and IFC

The Forum will take place in three sessions that will lead to the development of a framework to be carried forward and presented at the World Water Forum in Brazil in 2018.

The three sessions are on:

  • The wastewater challenge and reuse opportunity
  • Unlocking barriers and enabling reuse and recovery – innovative solutions/cases
  • A vision and roadmap for wastewater management and reuse to 2030

33rd AGUASAN Workshop: “Circular economy – transforming waste into resources”

The 2017 AGUASAcircular-economyN Workshop will focus on analysing successful and failed approaches for transitioning from linear to circular water and sanitation models.

The workshop takes place from June 26 to 30, 2017 in Spiez, Switzerland.

Circular economy has great potential to drive the Water and Sanitation 2030 Agenda forward because it aligns directly with the Sustainable Development Goal (SDG) 6.3 of improving water quality and substantially increasing recycling and safe reuse globally and SDG 6.4 of substantially increasing water-use efficiency across all sectors and ensuring sustainable withdrawals.

Key questions and issues: 

  • What does the circular economy concept entail?
  • Which flows are relevant?
  • Which stakeholders need to be involved and how?
  • How can demand for recovered products be created?
  • In which context do these stakeholders act?
  • What are the drivers and barriers influencing the transition towards a circular economy?
  • Which circular economy approaches can we learn from for overcoming the identified
  • How should change from linear to circular water and sanitation be managed?
  • How can health risks be managed?
  • How to address public perceptions associated with recycling and reusing of human waste?

Please find the invitation letter, announcement and pre-registration on the website: www.aguasan.ch. Registrations will be accepted until March 19th, 2017.

AGUASAN is an interdisciplinary Swiss Community of Practice (CoP) that brings together a broad range of specialists to promote wider and deeper understanding of key water and sanitation management issues in developing and transition countries. It builds on committed sector professionals from various specialised institutions involved in Swiss development cooperation, humanitarian aid and research. Since 1984, the CoP provides an exemplary, vibrant and most pertinent exchange platform and think-tank serving the water sector, and constitutes an essential link in the innovation and knowledge management strategy of the Swiss Agency for Development and Cooperation (SDC). Besides convening quarterly knowledge sharing events, every year members of the CoP organise an international AGUASAN Workshop in Switzerland

 

Positive Progress: 3 Trends in Wastewater Treatment

Water has become one of the foremost challenges affecting the world today. In developing countries, millions of people lack access to clean, safe water. Weather extremes, such as drought are creating dangerous situations; meanwhile, a new released report predicts that by year 2060, more than a billion people worldwide will live in cities at risk of major flooding as a result of climate change. drops-of-water-578897_1280-1

Then there’s the rapid population growth and economic development in regions, such as the Middle East, where water resources are being pushed well beyond natural limits. And as cities’ aging piping and distribution infrastructure continues to crumble, trillions of gallons of water are lost.

Municipalities in particular are taking the brunt of these challenges. Yet, I believe some of the greatest opportunities for solving the problems exist within their wastewater treatment plants. Last month, leaders in the global water sector convened in Munich, Germany, for the 50th anniversary of IFAT – an influential conference for innovation in water, sewage, waste and raw materials management. Three wastewater treatment trends – and solutions – dominated the discussion.

Startup Focused On Home Wastewater Reuse With ‘Biopipe’

Startup Focused On Home Wastewater Reuse With ‘Biopipe’ | Source: Water Online, April 21 2016 |

Should every home purify its own wastewater? A startup from young Turkish entrepreneurs says yes. 375_250-innovation_reg.png

Enes Kutluca, one of the founders, believes far too little wastewater is being reused. The global production of wastewater stands at about 165 billion cubic meters each day, and only about 2 percent gets recycled, according to Daily Sabah, an English-language daily newspaper published in Turkey.

“I think the wastewater treatment systems on the market have evolved in the wrong way,” Kutluca toldDaily Sabah. “There’s no sustainable wastewater treatment system that is suitable for everyone. People are thinking wastewater treatment is a luxury to have in homes.”

Kutluca observed that the sewer systems of modern cities are not efficient. For him, that was the starting point for innovation.

“We collect all wastewater from all houses with sewage networks, build kilometers of collection pipes and giant wastewater treatment plants. All of these cost millions of dollars and they don’t even use the treated water. We just let this usable water flow into seas and oceans. So, I started thinking that collecting wastewater from each house is not the best solution. What if I invent a wastewater treatment system that enables all houses to treat their own wastewater and reuse it again in their homes?” he said, per the report.

Enter Biopipe, a technology designed by Kutluca’s firm meant to solve this problem. Biopipe claims it is the world’s first and only sewage treatment pipe. How is works, as explained by Kutluca to Daily Sabah:

“Biopipe is the only innovative wastewater treatment system that does not produce sludge and it is patented in more than 55 countries. It is the result of years of research and development that has now become one of the most sustainable, eco-friendly and cost-effective wastewater treatment solutions in the world,” he said and added: “Today treatment systems on the market are complicated, expensive and not custom designed. Biopipe has a simple, innovative design, which is based around a natural treatment mechanism, and performed inside a pipe with the help of good bacteria without the need for any additional chemicals.”

UNEP launches awareness raising video on wastewater and oceans

A new short video “Wastewater: A widespread threat and missed resource” highlights the impacts of wastewater on coastal communities and ecosystems, and the benefits of improving its management. It is part of a series of ocean awareness videos titled Two Minutes on Oceans with Jim Toomey,  a collaboration between the popular American cartoonist Toomey and the United Nations Environment Programme (UNEP).

Safe use of wastewater in agriculture offers multiple benefits

Recycling urban wastewater and using it to grow food crops can help mitigate water scarcity problems and reduce water pollution, but the practice is not being as widely implemented as it should, according to a new UN food and agriculture organization (FAO) report [1]. The FAO has called for governments to increase the amount of treated wastewater being used for irrigation purposes as this will reduce costs for farmers and cities and improved water quality.

FAO report coverThe FAO report used case studies from Spain and Mexico to test methodologies for cost-benefit and cost-effective analyses of wastewater reuse projects. The Mexico case studies were drawn from three regions:

  • Mexico City & Tula Valley
  • Guanajuato City & La Purísima irrigation module
  • Durango City & Guadalupe Victoria irrigation module

“The case studies in this report show that safely harnessing wastewater for food production can offer a way to mitigate competition between cities and agriculture for water in regions of growing water scarcity,” said Pasquale Steduto, Deputy Director of FAO’s Land and Water Division. “In the right settings, it can also help to deal with urban wastewater effluent and downstream pollution.”
