Natural Water Systems and Treatment Technologies to cope with Water Shortages in Urbanised Areas (NaWaTech)

NaWaTech es un proyecto colaborativo indo-europeo cuyo objetivo es el de explorar, evaluar y mejorar el potencial, rendimiento y fiabilidad de diferentes sistemas de tratamiento de aguas para hacer frente a la escasez de agua en India. El concepto sobre el que se desarrolla el proyecto NaWaTech se basa en el uso optimizado de diferentes sistemas integrados según las necesidades y condiciones de cada una de las localizaciones elegidas: diferente naturaleza y grado de contaminación de los flujos de agua a tratar, posterior uso que pretende darse al agua tratada, etc. Los sistemas, además, se integran en el entorno urbano, lo que contribuye a potenciar además el desarrollo socio-económico de la comunidad. Este enfoque holístico contribuye a la disminución de la huella ecológica del agua y al mejor funcionamiento del ciclo local del agua, además de a la minimización de la contaminación de las fuentes de agua para usuarios intermediarios.

Providing adequate water supply and sanitation, particularly in urban areas, is a challenging task for governments throughout the world. This task is made even more difficult due to predicted dramatic global changes. In order to cope with water shortages in urban areas, there is a need for a paradigm shift from conventional end-of-pipe water management to an integrated approach. This integrated approach should include several actions such as: (i) interventions over the entire urban water cycle; (ii) optimisation of water use by reusing wastewater and preventing pollution of freshwater source; (iii) prioritisation of small-scale natural and technical systems, which are flexible, cost-effective and require low operation and maintenance. Natural water systems, such as manmade wetlands and sub-soil filtration and storage via soil aquifer treatment and bank filtration, are such systems. The project stands for natural water systems and treatment technologies to cope with water shortages in urbanised areas in India. The concept is based on optimised use of different urban water flows by treating each of these flows via a modular natural system taking into account the different nature and degree of pollution of the different water sources. Thus, it will cost-effectively improve the water quality of urban surface water and restore depleting groundwater sources. Due to the multi-barrier approach, these systems will also be able to treat heavily polluted water (i.e. wastewater) in order to reuse them and to supplement traditional sources to cope with water shortages today and in the future.
