NaWaTech COMMUNITY OF PRACTICE The NaWaTech Community of Practice (CoP) brings together key stakeholders from academia and research, industry, end users and decision makers in the water and sanitation sector. Experts from India and Europe join efforts within the CoP to find solutions to the water management crisis in urban India.

To assess the technical, financial and environmental potential of natural and technical water treatment technologies to cope with water shortages in urbanised areas in India. 2. To enhance the natural and technical water treatment systems for the production of recycled water to supplement water sources considering extreme climatic conditions and highly varying pollutions loads. 3. To disseminate, exploit and ensure the take- up in practice and mainstreaming of NaWaTech activities and outputs by key stakeholders. 4. To benefit Indian and European SMEs in the water sector by supporting the development of a local market for innovative water treatment technologies, and to train the SMEs on the NaWaTech approach. 5.

Taking into account the different nature and degree of pollution, each water flow is managed, treated and reused individually, supplementing traditional water sources to cope with shortages in Indian urban settlements. Blackwater and greywater (as separated streams or mixed) can be treated through the combination of an anaerobic process (producing energy and biogas) plus Constructed Wetlands (CW) or treated through aerobic technical water treatment systems (SBR or MBR). In both cases the effluent can be either discharged to the surface waters or reused in urban agriculture or landscaping. Stormwater can be collected and pre-treated in CW before it is filtered through the soil and stored in the aquifer. Rainwater can be collected on rooftops and parking lots and used in the households or fed into the aquifer. In addition, a cost-effective and viable post-treatment option can be developed based on different steps depending on the use to be given to the stream, and therefore water quality requirements. The different systems will be integrated into the urban scene providing additional socio-economic functions. This holistic approach will minimise the urban water footprint and enhance the water security of the area, as the water cycle is closed at a local level. It also minimises the pollution of water sources for downstream users. WATER CRISIS IN URBAN INDIA Today India is facing a water and sanitation crisis that might hinder the economical development of the nation, being water scarcity and pollution one of the most severe national-wide environmental problems. Demographic explosion and rapid urbanisation pose an unprecedented challenge for Indian cities, which still fail to deliver basic standards of living to their residents. Only about half of the cities in India are supplied with piped water, which in total represents 70.6% of the households. For cities with a population of one to five millions, their municipal authorities distribute water for a few hours per day, and during this time, the inadequate pipe pressure makes the whole process a struggle. The increasing demand for water has already triggered the decline in groundwater levels in many Indian cities, causing wells to run dry and energy costs to rise. About 15% of all Indian aquifers are in critical conditions, being expected to grow to 60% in the next 25 years unless measures are taken. According to the last census of 2011, only 72.6% of the households in urban areas had access to water closets, of which only the 32.7% were connected to a piped sewer system. The installed sewage treatment capacity is actually only 30%. This situation has detrimental effects on the quality of water resources, to the point that today 75% of all surface water across India is contaminated. Safe drinking water and sanitation is the condition for physical health and intellectual, social and economical activity and development. There is an urgent need of re-thinking the water and wastewater management in Indian cities, considering decentralised systems and innovative technologies, which require little or no energy and low maintenance costs, using locally available material and human resources.
