From Crystal Waters to Toxic Flow: The Ongoing Pollution of the Swat River

For thousands of years the River Swat and its canals have been a vital resource for lands, fields, and crops – as an excellent irrigation system the river’s waters are the foundation of the fertile and scenic Swat Valley. Swat River originates from the melting glaciers of the Hindu Kush in Kalam and winds its way down south for 240 kilometres through Khyber Pakhtunkhwa before merging with the Kabul River near Charsadda. According to the 2023 census, the population of Swat District is 2.68 million. It is the third-largest district in Khyber Pakhtunkhwa province by population. 

The picturesque Swat Valley, often dubbed the 'Switzerland of Pakistan' has experienced a significant increase in tourism, reaching its peak during the Eid al-Fitr celebrations in 2026, when its alpine resorts and river valleys were flooded with tens of thousands of domestic visitors. The increase in tourism is putting a strain on the environment, with rising pollution levels that are clearly visible, especially around popular picnic sites and waterways. Untreated industrial and tourism-related waste is increasingly polluting the Swat River. 

For twenty-five years Bakht Taj has been fishing in the Swat River and so did his father Bakht Momin before him. For local fishermen, the river is the foundation for feeding their families and making a living by selling trout fish in Mingora city markets. ‘The river was once green and clean. People came from far away to see it, but now you can’t even view it from the road because of encroachment and all the hotels, and the water is filthy,’ Taj told FairPlanet.

Researchers have detected significant levels of microplastics in the river system, which are linked to 'anthropogenic activities and improper waste management'. Another study shows how tourist litter is degrading water quality and harming freshwater ecosystems, impacting the behaviour of local fish.

Despite the alarming situation, the local administration and the government have taken only limited action to tackle the issue. The lack of proper waste management and ineffective enforcement of environmental regulations have allowed the situation to deteriorate further. Government organizations are also contributing to the damage to the ecosystem and biodiversity.

Taj stopped fishing in River Swat a year ago. Explaining his decision to FairPlanet, he said: ‘We cut open dead fish and found their flesh had turned red. The waters that once gave life have now become poison’. He added that the government and relevant authorities are aware of the situation, yet remain largely inactive. ‘They only produce paperwork, while no effective action is being taken.’

A drain for the tourism boom 

Swat River is becoming a drain for Swat’s tourism boom. According to the Khyber Pakhtunkhwa Department of Tourism, an estimated 600 hotels and 750 restaurants operate between Landakay and Kalam, said Zahid Khan, president of the All Hotels Association Swat. Only 60 hotels and 80 restaurants sit directly on the Swat River’s banks, but Zahid said the bigger problem is upstream: ‘Waste from 1.2 million people in Upper Swat goes directly into the river. There is no sewage system.’

Fazal Khaliq, a local journalist, traces the decline of water quality to unchecked dumping, and explained to FairPlanet: ’Garbage and sewage go directly into the river at multiple points. Dozens of fish species lived here in the River Swat. Now they have almost disappeared because of polluted and poisoned water’.

The toxic wastewater weakens fish immune systems and disrupts breeding. Khaliq told FairPlanet that the damage spreads even beyond the river itself: ‘The polluted water is negatively impacting the groundwater. Crops that used to grow on the river bank, such as strawberries, mustard and other vegetables and fruits are gone today’.

Khaliq said that the government could act to protect marine life by ‘strictly monitoring all relevant actors, such as fisheries, Water & Sanitation Services Company Swat (WSSC), the District administration, the Environmental Protection Agency and the irrigation departments’.

According to Akbar Zeb, an environmental expert at Swat, the Swat River crisis is accelerating in conjunction with different environmental destruction in the region and the effects of climate change; deforestation and heavier rainfall mean more floods, and as a result, erosion and muddy water enter the river. ‘We haven’t lost all aquatic life yet,’ Zeb said. ‘But with the current pace of pollution, the threats are serious. Floods in 2010, 2022, and 2025 already devastated fish stocks.’ 

Explaining the problem of pollution for aquatic life, he told FairPlanet: ‘aquatic life no longer receives clean water and sufficient oxygen, causing fish populations to decline and putting aquatic ecosystems at serious risk. Polluted water from streams and drains also flows into the Swat River’, further worsening the situation. He added: ‘We need to stop dumping waste into rivers and enforce rules at proper dumping sites. Rain and floods wash that garbage into the River Swat, killing aquatic life. This isn’t just the government’s job. If both the state and citizens act, we can save our rivers, fish and groundwater’. 

Notices Issues, Dumping Continues, Health Risks Increase

The Khyber Pakhtunkhwa Environmental Protection Agency (EPA) told FairPlanet that only twelve fish species remain but floods and pollution caused mass die-offs. EPA Director Afsar Khan confirmed that notices were issued to 32 hotels in nearby Kumrat this year for polluting waterways. He explained: ‘Designated dumping sites do exist. People just don’t use them.’

The Upper Swat Development Authority (USDA) told FairPlanet that it inspects about 140 hotels and restaurants weekly across Kalam, Bahrain, Madyan, and Malam Jabba. Saeed-ur-Rahman, USDA Spokesperson, said that out of these 27 were found discharging wastewater into water bodies: ‘We sealed ten, fined twelve, and issued notices to five more. All complied afterwards,’ he claimed. USDA has proposed treatment plants to the provincial government, but approval is pending.

Hotel owners say the state was the first actor to fail. Zahid Khan cites a stalled sewage project from Kalam to Landaky that would have been 80 per cent funded by foreign NGOs: ‘The Local Government minister didn’t approve it. So it died,’ he said. Hotels pay WSSC US$18 monthly for waste collection, Khan said: ‘If WSSC doesn’t do its job, the government should act against it.’

Meanwhile, locals keep bathing in the river during summer and continue eating its fish, unaware of health risks. No public health advisory exists, and multiple officials interviewed blamed other departments of Khyber Pakhtunkhwa Pakistan. 

A research study by environmental experts from regional universities found that samples of river water, fish, human hair, and nails tested for methylmercury levels 6 per cent higher than the WHO-recommended limit.

Lacking enforcement is the main problem

The Swat Valley in Khyber Pakhtunkhwa markets itself as “Pakistan’s ‘Switzerland’”- a hub for domestic tourism and fishing. Both are now threatened. Zeb explained that the problem isn’t missing laws, but their enforcement: ‘Encroachments must be stopped. Hotels must be banned from dumping. Tributaries must be protected. And we need afforestation,’ he said. ‘This isn’t just the local government’s job. If the state and public don’t act together, we lose freshwater, fish, and groundwater.’

EPA Director Khan agrees the solution is multi-agency, ‘Fisheries department must compensate for flood losses and push breeding programmes. Irrigation must be monitored. WSSC must collect waste. We can’t do it alone.’

For now, the Swat River in Khyber Pakhtunkhwa, Pakistan, continues to carry sewage and plastic waste, as well as the blame that each agency assigns to the next. The fishermen who knew the waters best are leaving. And the river that once defined a valley now threatens the people who depend on it. Former fisherman Taj believes that tourism and the river will die hand in hand: ‘Just imagine the situation five or ten years from now. The government knows about all the problems, but it shows negligence.’
