HYDERABAD — The Andhra Pradesh government has unveiled plans for a ₹150-crore sewage treatment plant in a bid to halt the flow of untreated domestic waste into the Tungabhadra River, a vital water source for millions in the region. Announced by Industries and Commerce Minister T.G. Bharat, the 35 million liters per day (MLD) facility is slated for completion within 18 months under the central government’s Atal Mission for Rejuvenation and Urban Transformation (AMRUT) 2.0 scheme. While the project signals a step toward addressing long-standing pollution concerns, its success hinges on overcoming historical challenges in infrastructure execution, regulatory enforcement, and inter-agency coordination.

What Happened
On Wednesday, Minister Bharat revealed that the proposed sewage treatment plant would be constructed to intercept and treat domestic sewage currently discharging into the Tungabhadra River. The facility, with a capacity of 35 MLD, is expected to serve urban areas in Andhra Pradesh where wastewater management infrastructure has lagged behind rapid population growth. The project falls under AMRUT 2.0, a centrally sponsored scheme that provides partial funding for urban infrastructure, with state governments covering the remaining costs.
The ₹150-crore allocation suggests a substantial financial commitment from the state, though a detailed breakdown of funding sources—including the central government’s share—has not been disclosed. Bharat did not specify the exact locations where diversion infrastructure, such as pipelines or pumping stations, would be installed to redirect sewage to the plant. Nor did he clarify whether the project would address industrial effluent, which environmental groups have previously identified as a major contributor to river pollution in the region.
Officials from the Andhra Pradesh Pollution Control Board (APPCB) were not immediately available to comment on the project’s compliance with existing environmental regulations, including the Central Pollution Control Board’s (CPCB) standards for treated wastewater discharge.

Why It Matters
The Tungabhadra River is a lifeline for agriculture, drinking water, and ecosystems across multiple districts in Andhra Pradesh and neighboring Karnataka. Decades of unchecked urban and industrial discharge have degraded water quality, posing public health risks and threatening aquatic biodiversity. The proposed treatment plant represents one of the state’s most significant interventions to date to mitigate pollution in the river, though its impact will depend on execution, enforcement, and complementary measures.
# Public Health and Environmental Implications
Untreated sewage introduces pathogens, heavy metals, and organic pollutants into water bodies, contaminating drinking water supplies and increasing the risk of waterborne diseases such as cholera, dysentery, and hepatitis. The Tungabhadra’s pollution has been a recurring concern for downstream communities, particularly in drought-prone regions where alternative water sources are scarce. A functional 35 MLD plant could reduce the biological oxygen demand (BOD) and fecal coliform levels in the river, improving water quality for millions.
However, environmental experts caution that sewage treatment plants alone may not suffice without parallel efforts to:
– Enforce industrial discharge norms: Factories and industrial units along the Tungabhadra have been accused of flouting effluent treatment standards, with APPCB data from 2023 showing that only 60% of industrial units in the region complied with pollution control regulations.
– Upgrade aging sewer networks: Many cities in Andhra Pradesh lack comprehensive sewerage systems, leading to overflows and untreated waste entering water bodies. The proposed plant’s effectiveness will depend on the state’s ability to expand and maintain interception infrastructure.
– Monitor treated effluent: The CPCB mandates that treated sewage meet specific quality standards before discharge. Past projects in India have faced criticism for operating below capacity or releasing inadequately treated water due to technical or operational failures.
# Economic and Political Stakes
The project’s announcement comes amid growing public and judicial scrutiny of river pollution in Andhra Pradesh. In 2024, the National Green Tribunal (NGT) directed the state government to submit a time-bound action plan for cleaning the Tungabhadra, following petitions highlighting the river’s deteriorating condition. The ₹150-crore plant could serve as a key component of the state’s response to these directives, potentially shielding it from further legal or regulatory penalties.
Politically, the project aligns with the central government’s push under AMRUT 2.0 to improve urban infrastructure, particularly in states governed by the Bharatiya Janata Party (BJP) or its allies. Andhra Pradesh, currently led by the YSR Congress Party, has sought to balance its development agenda with environmental commitments, though critics argue that implementation has often fallen short of promises.

Background and Context
# The Tungabhadra’s Pollution Crisis
The Tungabhadra River, a tributary of the Krishna River, originates in Karnataka and flows through Andhra Pradesh before merging with the Krishna near Sangameswaram. It supports irrigation for over 1.5 million hectares of farmland and provides drinking water to cities such as Kurnool, Anantapur, and Kadapa. However, decades of industrialization, urbanization, and poor waste management have severely degraded its water quality.
Key contributors to the river’s pollution include:
– Municipal sewage: Cities like Kurnool and Anantapur discharge an estimated 100 MLD of untreated sewage into the river, according to a 2023 report by the Andhra Pradesh Water Resources Department. The proposed 35 MLD plant would address only a fraction of this load, raising questions about the state’s broader strategy for sewage management.
– Industrial effluent: The Tungabhadra basin hosts numerous industries, including sugar mills, distilleries, and textile units, many of which have been accused of dumping untreated waste. A 2022 study by the Indian Institute of Science (IISc) found elevated levels of chromium, lead, and other heavy metals in the river, attributing them to industrial discharge.
– Agricultural runoff: Pesticides and fertilizers from farmland contribute to nutrient pollution, leading to algal blooms and oxygen depletion in the river.
# AMRUT 2.0 and India’s Sewage Treatment Gap
The Atal Mission for Rejuvenation and Urban Transformation (AMRUT) was launched in 2015 to improve urban infrastructure, with a focus on water supply, sewerage, and stormwater drainage. AMRUT 2.0, introduced in 2021, expanded the scheme’s scope to include sewage treatment and water recycling, with a target of providing 100% sewerage coverage in 500 cities by 2026.
Despite these ambitions, India faces a significant sewage treatment gap. According to the CPCB, the country’s installed sewage treatment capacity stands at 31,841 MLD, but only 20,235 MLD is operational—leaving a gap of over 11,000 MLD. Andhra Pradesh, with an estimated sewage generation of 1,200 MLD, has an installed treatment capacity of just 600 MLD, according to state government data.
Past sewage treatment projects in India have been plagued by delays and cost overruns. For example:
– A 2021 audit by the Comptroller and Auditor General (CAG) of India found that 40% of sewage treatment plants under AMRUT 1.0 were either non-operational or operating below capacity due to poor maintenance, lack of funding, or design flaws.
– In 2023, the NGT imposed a ₹100-crore fine on the Uttar Pradesh government for failing to curb pollution in the Ganga River, citing inadequate sewage treatment infrastructure despite multiple central and state-funded projects.

Competing Claims and Uncertainty
# Feasibility of the 18-Month Timeline
Minister Bharat’s assertion that the plant will be completed within 18 months has drawn skepticism from infrastructure experts. Sewage treatment projects in India typically face delays due to:
– Land acquisition: Securing land for treatment plants and pipeline networks can be contentious, particularly in densely populated urban areas. The Andhra Pradesh government has not disclosed whether land for the project has been identified or acquired.
– Bureaucratic hurdles: Clearances from multiple agencies, including the APPCB, the Water Resources Department, and local municipal bodies, can slow progress. The absence of public tenders or contractor details in the announcement raises concerns about transparency in the procurement process.
– Technical challenges: The plant’s effectiveness will depend on the state’s ability to intercept existing sewage flows, which may require extensive pipeline networks. If these networks are not built concurrently, the plant could remain underutilized.
# Funding and Cost-Sharing
While the ₹150-crore allocation suggests a significant state contribution, the exact cost-sharing arrangement between the central and state governments remains unclear. Under AMRUT 2.0, the central government typically funds 50% of project costs in non-special category states, with the state covering the remainder. However, additional expenses, such as land acquisition or pipeline construction, may fall entirely on the state’s shoulders.
Environmental activists have also questioned whether the project’s budget accounts for long-term operational costs, including maintenance, electricity, and staffing. A 2022 study by the Centre for Science and Environment (CSE) found that many sewage treatment plants in India operate at a loss due to high energy consumption and inadequate user fees.
# Industrial Pollution and Regulatory Enforcement
The announcement focuses on domestic sewage but does not address industrial effluent, a major source of Tungabhadra’s pollution. Environmental groups, including the Andhra Pradesh chapter of the National Alliance of People’s Movements (NAPM), have accused the state government of lax enforcement of industrial discharge norms. A 2023 report by the APPCB found that 40% of industrial units in the Tungabhadra basin were non-compliant with pollution control regulations, yet only 12% faced penalties.
The state’s ability to enforce these norms will be critical to the project’s success. Without stricter monitoring and penalties for violators, the plant may only address a fraction of the river’s pollution load.

What to Watch Next
1. Tendering and Contractor Selection
The state government is expected to release tenders for the project in the coming months. The transparency of the procurement process, including the selection criteria for contractors, will be a key indicator of the project’s credibility. Past sewage treatment projects in India have been marred by allegations of corruption and favoritism in contractor selection.
2. Land Acquisition and Pipeline Infrastructure
The government’s ability to acquire land and construct interception pipelines will determine whether the plant can operate at full capacity. Delays in these areas could push back the 18-month timeline.
3. Regulatory Clearances
The project will require approvals from the APPCB, the Ministry of Environment, Forest and Climate Change (MoEFCC), and local municipal bodies. Any objections or conditions imposed by these agencies could delay construction or increase costs.
4. Industrial Compliance Measures
The state’s willingness to crack down on non-compliant industries will be critical to the plant’s impact. Watch for announcements of stricter monitoring, penalties, or incentives for industries to adopt cleaner technologies.
5. Public and Judicial Scrutiny
Environmental groups and the NGT may seek updates on the project’s progress, particularly in light of the state’s past failures to meet pollution control targets. Any legal challenges or public protests could influence the project’s trajectory.
6. Funding Breakdown and Operational Costs
The state government is expected to release a detailed cost breakdown, including the central government’s share and provisions for long-term maintenance. Clarity on these fronts will be essential to assess the project’s sustainability.
