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.”

Discussion on a new SNV/ISF learning paper on “Septage Transfer Stations”

On Wednesday 24 June a discussion on a new SNV/ISF learning paper, namely on Septage Transfer Stations, is starting. This discussion will be running on the Faecal sludge transport sub-category of the sanitation systems group category on the SuSanA Forum and in parallel also on the WASH Asia urban san Dgroup.

The topic of Septage Transfer Stations has come up as one of the learning priorities, because it is an essential part of a faecal sludge management solution in cities with narrow roads and large distances to treatment facilities. In this learning paper we brought together existing knowledge on this topic, and we found out that there are only a few good examples. Through this discussion we are not only hoping to share the paper, but also to add examples and insight to it from your collective experience.

What will we discuss?

There will be 3 topics and each topic will run for one week, from Wednesday till Tuesday. At the end of the discussion, we’ll make a summary paper as input for the workshop. Below are the three topics.

Week dates topic

Week 1: 24 June- 30 June Different options for septage transfer stations

Week 2: 1 July- 7 July General considerations for septage transfer stations

Week 3: 8 July-14 July Reflections on management arrangements for septage transfer stations

After the discussion, we will share an updated version of the learning paper on Septage Transfer Stations.

How does it work?

We are making the full learning paper available to you on the Faecal sludge transport subgroup and the SuSanA Discussion Forum.

In addition to this, we will break up the information according to the above blocks. On the first day of the discussion, 24 June, you will find some questions in your inbox. Everybody is invited to share their ideas, comments and examples, responding to the message. All experiences and opinions are welcome and please don’t be shy to contribute.

On the last day of each discussion week, each Tuesday, all messages of the week will be processed and integrated into a chapter of the summary document. This will be the same for all 3 topics.

For more information please visit the SuSanA Forum.

Looking forward to hear from all of you over the coming weeks!

Sanitation and Drainage in Cities – Environment & Urbanization, April 2015

Sanitation and Drainage in CitiesEnvironment & Urbanization, April 2015

Editorial – Is it possible to reach low-income urban dwellers with good-quality sanitation? (Full text) by David Satterthwaite, Diana Mitlin, and Sheridan Bartlett.

Container-based sanitation: assessing costs and effectiveness of excreta management in Cap Haitien, Haiti. (Full text) by Sebastien Tilmans, Kory Russel, Rachel Sklar, Leah Page, Sasha Kramer, and Jennifer Davis.
Container-based sanitation (CBS) – in which wastes are captured in sealable containers that are then transported to treatment facilities – is an alternative sanitation option in urban areas where on-site sanitation and sewerage are infeasible. This paper presents the results of a pilot household CBS service in Cap Haitien, Haiti. We quantify the excreta generated weekly in a dense urban slum,(1) the proportion safely removed via container-based public and household toilets, and the costs associated with these systems. The CBS service yielded an approximately 3.5-fold decrease in the unmanaged share of faeces produced, and nearly eliminated the reported use of open defecation and “flying toilets” among service recipients. The costs of this pilot small-scale service were higher than those of large-scale waterborne sewerage, but economies of scale have the potential to reduce CBS costs over time. The paper concludes with a discussion of planning and policy implications of incorporating CBS into the menu of sanitation options for rapidly growing cities.

IWA – Faecal Sludge Management, systems approach for implementation and operation

This link also has a info on an online course, how to order the hardcopy, etc;

The first book dedicated to Faecal Sludge Management (FSM) has been published recently by IWA Publishing. The book ‘Faecal Sludge Management, systems approach for implementation and operation‘ as well as the individual chapters can be downloaded from this page. Damir Brdjanovic, Professor of Sanitary Engineering and Mariska Ronteltap, Senior Lecturer of Sanitary Engineering at UNESCO-IHE have edited the book, together with Dr. Linda Strande, director of the Excreta and Wastewater Management group at EAWAG (the Swiss Federal Institute of Aquatic Science and Technology). The book is funded by the Bill & Melinda Gates Foundation and the Swiss Agency for Development and Cooperation. fsm_book_0



The appropriate and adequate management of faecal sludge deriving from onsite technologies is imperative for the protection of human and environmental health. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of this rapidly evolving field, and presents an integrated approach that includes technology, management and planning. It addresses the planning and organization of the entire faecal sludge management service chain, from the collection and transport of sludge and treatment options, to the final enduse or disposal of treated sludge. In addition to providing fundamentals and an overview of technologies, the book goes into details of operational, institutional and financial aspects, and provides guidance on how to plan a city-level faecal sludge management project with the involvement of all the stakeholders.
