Managing sewage waste
The Ganges River, or Ganga, is revered by the Indian people, who consider it sacred. The river is also a source of livelihood for many, providing water for agriculture, fisheries, transportation, and domestic use. However, the river is facing formidable pollution pressures, with nearly 70% of its surface water resources contaminated by biological, toxic, organic, and inorganic pollutants.
Sewage Waste Management
The main objective of the Ganga Action Plan (GAP) was to improve water quality through the interception, diversion, and treatment of domestic sewage. The plan also aimed to prevent toxic and industrial chemical wastes from identified polluting units from entering the river. Despite this, billions of litres of untreated sewage continue to be dumped into the river daily, wreaking havoc on the river's natural ecosystem.
To address this issue, comprehensive city and urban river management plans must put the river line ecosystem at the centre of their planning. This includes exploring in situ wastewater treatment options, such as zero-discharge technologies, which can process waste on-site at the household, village, and colony levels. Regular and transparent monitoring of river water quality is also essential to prevent waterborne diseases and should be made accessible to the public.
Bio-digester toilets are another solution, as they can process sewage waste on-site, reducing the volume of wastewater entering the river. Additionally, rigorous observation and monitoring of wastewater from industrial sources are necessary, with strict enforcement of environmental regulations and accountability for non-compliance.
The Indian government has also embarked on a campaign to ensure that no untreated municipal sewage or industrial runoff enters the river. This includes investing in wastewater collection and treatment infrastructure, as well as solid waste management and riverfront development. The National Mission for Clean Ganga (NMCG) coordinates the river's clean-up program, with State Program Management Groups (SPMGs) established in all five mainstem states. These groups are implementing investments in new sewage treatment capacity and sewerage networks in urban centres along the river.

Banning religious waste dumping
The Ganges River is sacred to Hindus, who worship it as "Mother Ganges", a source of life and a sustainer of civilization. However, the river has become severely polluted, threatening the health and well-being of those who depend on it. While various initiatives, such as the Ganga Action Plan, have been launched to address this issue, the complexity of the challenge calls for integrated and comprehensive solutions.
One significant contributor to the pollution of the Ganges is the dumping of religious waste. Traditional Hindu beliefs hold that cremation on the river's banks and floating in the Ganges will cleanse the sins of the deceased and lead them to salvation. As a result, an estimated 40,000 bodies are cremated annually and deposited into the river in Varanasi alone. Many of these bodies are only partially burned due to the high cost of cremation wood. In addition to human remains, other religious waste, such as temple flowers and offerings, further contribute to the pollution.
To address the issue of religious waste dumping, several measures can be implemented as part of a comprehensive strategy:
- Promoting alternative cremation methods: Constructing electric crematoria near the ghats in Varanasi and other holy riverside towns can provide a more environmentally friendly option for cremations. This not only reduces river pollution but also preserves trees by lowering the demand for funeral pyres.
- Proper waste disposal and management: Implementing waste management systems specifically for religious waste can help ensure that offerings and leftover flowers are collected and disposed of or recycled properly. For example, the city of Varanasi has installed marked bins along the riverbanks and floating barriers in the river to collect temple flowers, which are then composted or used to create incense sticks.
- Education and awareness: Educating riverside residents and religious devotees about the environmental impact of waste dumping can foster a sense of responsibility for keeping the river clean. Initiatives such as local advertisements and public announcements can encourage people to change their habits and refrain from polluting the river.
- Enforcement and penalties: Establishing and enforcing environmental regulations specifically targeting religious waste dumping can act as a deterrent. Implementing fines or other legal consequences for those who violate these regulations can further emphasize the importance of maintaining the river's sanctity.
- Collaboration between authorities and religious leaders: Working closely with religious leaders and organizations can help ensure that any measures taken are culturally sensitive and aligned with religious values. By involving religious authorities in the decision-making process, the implementation of solutions is more likely to be effective and widely accepted.
By implementing these measures and integrating them into a comprehensive strategy that addresses the various sources of pollution in the Ganges, significant progress can be made toward reducing religious waste dumping and improving the overall health of the river.
