What You'll Learn
Untreated sewage and industrial effluents
The Musi River, which flows through the city of Hyderabad in India, is one of the most polluted rivers worldwide. The rapid increase in pollution levels can be attributed to a range of factors, with untreated sewage and industrial effluents being key contributors.
Hyderabad, with a metropolitan population of over 7.5 million people, discharges a substantial amount of untreated sewage into the Musi River. A Central Pollution Control Board report from June 2019 revealed that only 49% of the city's sewage is treated, while the remaining 51% is released directly into the river. This untreated sewage turns the river into a foul-smelling slurry, posing significant health and environmental risks.
The booming population of Hyderabad relies on the Musi River as their main source of sanitation and wastewater management. However, the inadequate infrastructure and treatment facilities have resulted in the river becoming a dumping ground for sewage. The river basin receives an estimated 600 million to 654 million liters of wastewater daily, impacting the water quality and causing widespread pollution.
In addition to untreated sewage, industrial effluents also play a role in polluting the Musi River. While they constitute a smaller percentage of the pollutants, these effluents are directly discharged into the river, adding to the overall degradation of water quality. Improper disposal of industrial waste introduces various chemicals and contaminants into the river ecosystem, further exacerbating the pollution crisis.
The consequences of untreated sewage and industrial effluents in the Musi River are far-reaching. The river water, heavily laden with pollutants, has led to the development of antibiotic resistance in its aquatic environment. Furthermore, the contaminated river water seeps into the ground, affecting underground aquifers and altering the water table. The pollution has also impacted agriculture, stockbreeding, and fishing, creating unsafe conditions for food intake and adversely affecting the economic well-being of the surrounding communities.

Use of polluted water for irrigation
The Musi River in India is one of the most polluted rivers in the world. The river receives about 600-654 million liters of wastewater every day from the city of Hyderabad, which is located on its banks. The untreated sewage water contains heavy metals and antibiotics, leading to the development of antibiotic-resistant bacteria in the river's aquatic environment. This has resulted in a high incidence of diseases such as arthritis, diarrhea, skin allergies, stomach pain, malaria, food poisoning, and eye diseases among the population. The pollution has also impacted agriculture, stockbreeding, and fishing, affecting the food intake and economic conditions of the downstream villages.
Irrigation is a crucial aspect of agriculture, but it can also contribute to water pollution if not properly managed. One of the main concerns with irrigation is the depletion of underground aquifers through overdrafting. Over-irrigation can lead to waterlogging and soil salinization, which can damage the soil structure and affect plant growth. The excess water can also carry agricultural chemicals, such as biocides and fertilizers, into downstream waterways, deteriorating the water quality and rendering it unfit for industrial, municipal, and household use.
To address these issues, proper water management practices and treatment facilities are necessary. Water quality testing is essential to ensure that irrigation water meets the standards for plant growth and does not contain harmful levels of contaminants. Reconditioning of reclaimed water, runoff water, or recycled water may be required to remove disease organisms, soluble salts, and traces of organic chemicals. Additionally, filtration can be used to eliminate suspended solids that can clog irrigation systems.
The sustainability of irrigation projects relies on considering their environmental impacts and maintaining the implemented schemes. Health appraisals and mitigation measures are often overlooked in irrigation projects, but they are crucial for minimizing adverse effects on human health and the environment. By addressing these challenges, it is possible to balance the benefits of increased crop yield through irrigation with the preservation of water quality and the health of ecosystems and communities.
In the case of the Musi River, the implementation of irrigation weirs has shown promising results. These structures, placed downstream of Hyderabad, have helped improve the river water quality, reducing the impact of pollution on the villages that depend on the river for their livelihood. However, more comprehensive solutions, such as the development of sewage treatment plants, are needed to address the pollution issues effectively and restore the Musi River to its old glory.
