NAWATECH: Water treatments for urbanized areas in India

NaWaTech has been a successful three and a half year project carried out in the cities of Pune and Nagpur in the Maharashtra region, India, based on the optimized use of the different urban water flows through its management, treatment and reuse taking into account its nature and degree of contamination and the subsequent use of the treated water. The research also covered financial, environmental and institutional sustainability aspects of those systems to develop and bring to market an economically efficient multi-barrier water management concept: the NaWaTech system.

BIOAZUL was in charge of the design, installation, commissioning, operation and monitoring of a system composed of a Sequential Batch Reactor (SBR) and a Membrane Bioreactor (MBR) in Amanora Park Town, Pune. Both systems can treat urban wastewater flows for reuse and complement traditional water sources. In addition, other natural wastewater treatment systems were designed in five more locations. Approximately 4,000 people will benefit from the water treated by these systems, thus reducing dependence on the Municipal Supply Corporation.

A final publication was generated that summarizes all the work carried out in the project, as well as the results obtained. This publication was the 25th publication of the “Sustainable Sanitation Practice” publication (EcoSan Club, Vienna, Austria, Sustainable Sanitation Practice (SSP), Issue 25, January 2016, ISSN: 2308-5797) of the Sustainable Sanitation Alliance (SuSanA) and that it is available in English at its library.

There is more detailed information about the project on the NaWaKit Platform.

OBJECTIVES

  • Assess the technical, financial and environmental potential of compact natural and technological water treatment systems to address water scarcity in urbanized areas in India.
  • Improve these water treatment systems for the production of recycled water that complements existing water resources considering extreme climatic conditions and differences in the type and load of pollution of waters (for example, monsoons).
  • Disseminate, exploit and ensure the implementation of NaWaTech results involving all stakeholders (end users, service providers, authorities, etc.).
  • Develop technical guides, tools and manuals for the design, implementation and operation and maintenance, as well as recommendations on current legislation.
  • Guarantee the interest and potential benefit for SMEs in the sector by supporting the development of a local market, education and training, support for entrepreneurs and the inclusion of local companies in the implementation phase of the project.
  • Create an enabling institutional environment to enable results to be put into practice (for example, by aligning NaWaTech initiatives with existing urban water management plans, strategies and policies).
  • Establish the foundations for a long-term EU-India cooperation in water technologies, as well as bridges between research institutions.

RESULTS OBTAINED

The project ended in December 2015 and very valuable results have been generated for the development of the sector in India:

  • Identification of technical, economic and environmental sustainability criteria for the NaWaTech context; and of the systems with the greatest potential based on these criteria.
  • Evaluation of the potential of the systems contemplated in NaWaTech for the treatment of different urban water flows, including an analysis of costs and their adaptability to local conditions, as well as their optimization to the Indian context.
  • Design, implementation, operation and monitoring of 6 water treatment systems.
  • Creation and consolidation of a “Work Community” (CoP) made up of different types of organizations involved in water management (citizen representatives, researchers, suppliers, authorities, etc.
  • Europe-India cultural and academic exchange and knowledge transfer through student exchange for the development of different projects and establishing long-term research cooperation.
  • Development of the NaWaKit, which includes all the dissemination materials produced for the project (video, technical notes, case studies, recommendations on current legislation, etc.).
  • Involvement of key actors (SMEs and end users) through workshops and international seminars.
  • Organization of a Final Conference that took place from April 21 to 23, 2016 in Pune (India), in which the results of NaWaTech, as well as other projects of the Europe-India call, were presented.
