High population growth, increasing urbanization and rapid economic development are exerting pressure on the already scarce water resources in India. Untreated wastewater from human settlements reaching natural waterways is very common contributing to environmental pollution, which directly affects the availability of fresh water for human consumption. Therefore, treatment and reuse of wastewater can play an important role in addressing some of the urban water challenges in India. Conventional treatment plants have many challenges, therefore, natural treatment systems are viewed as a cost-effective alternative, which are more suitable in the Indian context. For example, they are not reliant on electricity, easier to maintain, can be part of small decentralised systems and work well in tropical climates. This study presents a rapid sustainability assessment and a review of the potential of natural treatment systems in India. The preliminary results show that the natural treatment systems have a high potential for wastewater treatment. However, there are still gaps in knowledge related to aspects that hinder the sustainable functioning of these treatment systems.

High population growth, increasing urbanization and rapid economic development are exerting pressure on the already scarce water resources in India. Treatment and reuse of wastewater can play an important role in addressing some of the urban water challenges. Conventional treatment plants have many challenges, therefore, natural treatment systems (NTSs) are viewed as a cost-effective alternative, which are more suitable in the Indian context. This study builds on a desktop study of NTSs and presents a rapid sustainability assessment of 12 NTSs, highlighting the potential and viability of NTSs in India. The results show that the NTSs have a high potential for wastewater treatment. However, there are still gaps in knowledge related to aspects that hinder the sustainability of the systems. Risks associated with reuse of treated wastewater in agriculture, operational problems and social acceptance were perceived as frequent challenges. Self-sustaining financing methods and the use of by-products were viewed as added benefits.

When flowing through Hyderabad, the capital of Telangana, India, the Musi River picks up (partially) treated and untreated sewage from the city. Downstream of the city, farmers use this water for the irrigation of rice and vegetables. Treatment of the river water before it is used for irrigation would address the resulting risks for health and the environment. To keep the costs and operational efforts low for the farmers, the use of constructed wetlands is viewed as a suitable option. Towards this end, the paper investigates the interests and perceptions of government stakeholders and farmers on the treatment of wastewater for irrigation and further explores the consumer willingness to pay a higher price for cleaner produced vegetables. Full cost recovery from farmers and consumers cannot be expected, if mass scale treatment of irrigation water is implemented. Instead, both consumers and farmers would expect that the government supports treatment of irrigation water. Most stakeholders associated with the government weigh health and environment so high, that these criteria outweigh cost concerns. They also support the banning of irrigation with polluted water. However, fining farmers for using untreated river water would penalize them for pollution caused by others. Therefore public funding of irrigation water treatment is recommended.
