Sanitation and Wastewater

Seminar at Singapore International Water Week 2018 // Dealing with the Sanitation Nexus: The Need for Technology Disruption

Conventionally-reticulated sanitation requires high investment costs and substantial access to energy and water to operate its systems. Against the challenges of water security, availability, climate variability, rising energy costs and growing concerns of new and emerging pathogens, the questions posed are whether this model can be sustainable into the future. At this time, global utilities and governments are increasing their efforts to meet the SDG goals. In regards to sanitation, they will focus on the majority of unserved communities in rural, urban and peri-urban areas in developing and developed cities.

About 2 billion people do not have access to adequate sanitation, and additional 2.5 billion use non-sewered sanitation systems (off-grid) which are not always properly managed. Despite the many advantages of off the grid and waterless toilet and sanitation technologies, especially in a water-scare country, they are not attracting decision maker’s attention.   There is still a weak understanding of policies and regulations needed to promote alternative solutions to sewer based systems, and especially how sanitation services can be priced in cities and communities without sewer. 

The first set of disruptive technologies are moving from prototype to manufacturing, supported by a number of implementation and business models for its role out.  The WRC and the Foundation are working towards large scale demonstration.  This session aims to share some of the new developments and technologies emanating from the Gates Sanitation Challenge and the Water research Commission, as well as others. 

It will highlight current experiences and lessons, and will stimulate or provoke thinking towards a sanitation future free of wastewater and faecal sludges.

  • Greater awareness of new technologies and developments
  • Share best practices and lessons
  • Inform policy and process which may change design and regulations
  • Establish a Community of practice
  • Discuss how off the grid systems can influence city wide sanitation planning and developments.
  • Development of standards and ISO processes for technologies

The case studies will share the latest progress on innovative sanitation service delivery models as well as the next generation of technologies currently being developed for the launch a new sanitation industry.  We hope to stimulate a dialogue with key leading thinkers in this field, on the timing and the opportunity at hand in more holistically dealing with the nexus of toilet - wastewater - pollution - energy.

Conference // Water Storage and Hydropower Development for Africa

The connection of energy and water is most obvious in electricity generation through hydropower. Plus dams have an important impact on the environemtn, on water availability upstream and downstream, and thus on food production and food security. The AFRICA 2019 conference will bring together industry professionals in Namibia, a country with a variety of dams, to discuss water and energy issues relevant to Africa.

Session at EGU General Assembly 2019 // Hydropower and Other Renewable Energy Sources: Integration and Planning amid the Water-Energy Nexus

The transition to a low-carbon economy and programs of nuclear power phase-out will require the development of innovative methods to integrate renewable sources of energy while minimizing the additional pressure on closely connected ecosystems. This session at the EGU General Assembly 2019 solicits contributions that describe, characterize, or model distributed renewable energy sources at different spatial and temporal scales that are relevant for the electricity systems, their interactions,...
