In India, a country with a population of 1.4 billion, access to clean water remains a big problem. The water crisis here can be described by two important challenges: poor water quality by contamination and inadequate quantity by scarcity and overuse.

According to a 2023 report by UNESCO, 35 million Indians lack access to safe water, and large number lack access to safe sanitation facilities. Millions are forced to rely on contaminated water sources for drinking, cooking, and bathing, with horrific health consequences. Children suffer the most, with some 1.5 million estimated deaths annually from diarrhoea due to waterborne pathogens. This crisis underlines the urgency for solutions that ensure clean water as a right common to all mankind, prioritising access, affordability, and health for everyone.

Clean water, according to the United Nations, needs to be sufficient, safe, acceptable, physically accessible, and affordable for home and personal consumption. Sanitation facilities must be hygienic, safe, and culturally appropriate, with dignity and privacy.

In India, conditions like seasonal pollution of water during the monsoon from agricultural runoffs, untreated sewage, geological causes and industrial effluents add complexity to the challenge of adhering to these standards. Potable water is polluted with dangerous contaminants like bacteria, viruses, heavy metals, and high levels of TDS (Total Dissolved Solids), which usually range above 500 ppm (parts per million) in the majority of Indian regions.

Ethical Initiatives to Realise Water Access

The United Nations’ identification of water and sanitation as human rights emphasises a human rights-based approach (HRBA) to addressing the two issues. In India, this strategy is being implemented through initiatives like the Jal Jeevan Mission (JJM), an ambition to provide tap water connections to all rural households. Until August 2024, JJM has provided connections to 15.07 crore rural households (77.98%), significantly closing the gap between rural and urban India. The program targets marginalised groups, such as women, children, and lower caste people, with inclusive access without discrimination.

The water purification industry is also taking the lead by creating affordable and effective water purification technologies specifically adapted to India's specific challenges. For example, technologies such as Zero Water Waste Technology and TDS Controllers respond to high-TDS conditions and water scarcity in the country, making purified water accessible as well as sustainable.

Overcoming Challenges

Indian rivers, being saturated with industrial effluent and untreated sewage, remain a nagging problem. The National Mission for Clean Ganga (NMCG) has sanctioned 488 projects with a total of ₹39,730 crore, including 203 sewerage infrastructure projects to create 6,255 MLD sewage treatment capacity, to combat river pollution.

Additionally, geographical and infrastructural challenges such as uneven terrain, scattered rural habitations, and lack of dependable water sources complicate water supply infrastructure. Water is utilised by farmers as a low-cost input, leading to overconsumption and pollution through runoff. JJM and Jal Shakti Abhiyan are mitigating these challenges through in-village piped water systems, networks of bulk water transfer, and implementing awareness campaigns and sustainable practices like rainwater harvesting and grey-water reuse.

Creating Awareness for Clean Water as a Human Right

Over 24.64 lakh women in Village Water & Sanitation Committees (VWsCs) have been trained to carry out water sample testing, allowing communities to test the quality of their water independently. Awareness campaigns, including the Jal Shakti Abhiyan's "Catch the Rain" campaign, encourage practices like rainwater harvesting and emphasise contributions made by women towards saving water.

Government health programs and non-profits also educate the public on the link between contaminated water and disease outbreaks of cholera and typhoid, generating demand for water purifiers. In making clean water a human right, these programs align with the UN's Sustainable Development Goals, particularly the commitment to "leave no one behind".

Emerging Technologies for Efficiency and Accessibility

The RO market is evolving to make water purifiers more efficient and accessible for Indian consumers. The inclusion of IoT features like real-time monitoring of water quality and filter reminder alerts adds to the ease of use as well as maintaining performance consistency. Instant water softeners in RO systems efficiently address India's hard water issues, reducing high hardness levels and preventing scaling to deliver safe, soft drinking water.

Projects such as Water4Crops utilise constructed wetlands to purify wastewater, lowering chemical oxygen demand by 30–92% and allowing it to be safely reused in farming, thereby saving freshwater resources.

All these developments go hand-in-hand with the increased need for trustworthy, easy-to-use, and affordable purification systems, especially in rural settings.

A Sustainable and Inclusive Future

The path to universal access to clean water in India is lined with optimism and innovation. The success of Jal Jeevan Mission and industry advancements show a common commitment towards accessibility and affordability.

The industry's commitment to ethical solutions, ranging from low-cost purification for poor families to grassroots-led awareness, means that even vulnerable groups are not left behind. As India continues to invest and innovate in water security, the vision for a healthier, fairer future—where all homes have access to affordable, clean water—is within reach.
