Monsoon nears, but Kathmandu’s drinking water safety fears return as testing halts

Drinking water safety in Nepal's capital is once again a concern as the monsoon season approaches. Recent tests in Kathmandu district revealed hazardous microbes in more than 25% of water samples. However, the Public Health Office has suspended further testing, leaving authorities uncertain about the water quality consumed by the city's residents.

Officials cited "various constraints" for the halt in testing, with hopes to resume soon. This situation is particularly worrying given the intensified pre-monsoon rainfall, which typically contaminates water sources with harmful microbes. Tests had previously detected E. coli and faecal coliform in tap water from several municipalities within the Kathmandu Valley, indicating sewage contamination.

Contaminated drinking water remains a persistent challenge in Nepal, despite past investments in water infrastructure. The country is highly susceptible to water-borne illnesses such as diarrhea, dysentery, typhoid, hepatitis, and cholera, which affect thousands annually. Last year's cholera outbreak, which led to deaths and hundreds of infections, required vaccination efforts to control. This year has already seen outbreaks of diarrheal diseases, including cholera, in multiple districts.

Doctors report a surge in patients with diarrheal diseases, underscoring the immediate health risks. The lack of widespread water quality testing amid these growing threats has amplified concerns about potential public health hazards.

We could not continue testing of water samples due to various constraints. We will resume testing within our jurisdiction soon.
