description: <strong>Summary</strong>

Saph Pani was an India-EU collaborative project with a duration of three years. The project aimed to improve natural water treatment systems such as bank filtration (BF), managed aquifer recharge (MAR) and natural treatment systems (NTS) for wastewater treatment (e.g. constructed wetlands) in India by building on a combination of local and international expertise. An enhancement of water resources and water supply, particularly in water stressed urban and peri-urban areas was targeted. The means to reach this impact was to strengthen the scientific understanding of the performance-determining<br>
processes occurring in the root, soil and aquifer zones of the relevant regions and consider the removal and fate of important water quality parameters such as pathogenic microorganisms and respective indicators, organic substances, nutrients and metals. The consortium studied the three technologies on a total of nine sites in different parts of the Indian sub-continent.

A good understanding of bank filtration performance as a function of operation and design was established. The applicability of technology was extended through an assessment of flood risks and development of flood-proof designs and other measures. A survey of other existing sites broadened the experience base and allowed identification of potential new BF sites and the characteristics of such sites. Special attention was given to the polluted waters (nitrogen species) in Delhi and the adjoining aquifers, representative of the conditions in the Gangetic plain. The specific cost of production was determined to be less<br>
than 0.1 €/m3, a factor three lower than surface water abstraction followed by conventional treatment.

Based on field results and modeling, MAR performance was reliably quantified, in particular for a percolation pond in a hard rock setting and a check dam in alluvial setting. Up to now limited data on MAR influence on quality was available and the project gave new insights, for example with regards to geogenic fluoride contamination, pathogen dieoff, organic pollutant elimination and dilution effects.

A catchment with a natural peri-urban wetland was comprehensively described (hydrology, water quality) and modeled which gave new insights in the cleaning capacity and options for improvement of the situation of the local farmers. On the national scale a complete inventory of Indian public NTS for wastewater treatment was performed. 41structures representing five different technologies (horizontal sub-surface flow constructed wetlands, duckweed ponds, waste stabilization ponds, polishing ponds and Karnal-type constructed wetlands) were analysed on-site. Also pilot constructed wetlands trials were performed and the knowledge gained will facilitate planning and designing of NTS structures for wastewater treatment including post-treatment to enhance potential for recycling and reuse.

Current pre- and post-treatments for NTS in India and the critical water quality parameters of concern were determined. The partner knowledge base together with lab and field studies allowed us to derive recommendations for pre- and post-treatment options for different uses. Also, a matrix to select appropriate treatment was prepared based on data on cost and elimination capacity. It can be used by designers and planners for preliminary selection of NTSs and associated pre- and post-treatment systems. Human health risks, economical and institutional viability and social risk acceptance  were assessed on selected project sites and recommendations and sustainable  business models resulted. One example is NTS for wastewater treatment managed by local communities providing both irrigation water and fodder for cattle and thus allowing an increased income.

The project resulted in around 30 articles in scientific journals and the Saph Pani Handbook presenting an overview of the most important findings and striking success stories of the project. Results were disseminated through a project website, newsletters, leaflets for the general public, 4 targeted courses, practitioner meetings and over 40 events, culminating with the Saph Pani final conference with attendance of the Indian Minister of Water Resources, over 100 invited scientists, senior level policy and decisionmakers and presentations also from other current EU-India projects on NTS.
