Landslides triggered by incessant rain increased turbidity in Karnaphuli water.
Production of Chittagong Water Supply and Sewerage Authority (CWasa) has decreased as the level of turbidity in the Karnaphuli river water increased due to the recent landslides triggered by incessant rain in Chittagong and Rangamati districts.
Due to the increased level of mud in the river water, production in two of the Cwasa water treatment plants got hampered, resulting in people suffering from a scarcity of water for the last three days.
According to CWasa, it can supply 31 crore litres of water per day in the city against a demand of 50 crore. But the supply dropped to 21 crore.
Rainwater and mud came down heavily from hills and fell into the Karnaphuli river and canals during the heavy rain on June 11 and June 12, increasing the turbidity of the river water, said CWasa officials.
Asif Ahmed, a resident of Bakalia DC Road area, said his landlord used to supply water two times a day. “But we didn’t get any water on Tuesday. From Wednesday to Friday, we got water just once a day. I had to buy water at a high rate to meet our daily demand.
Echoing him, Swapna Chakraborty of Katalganj area, yesterday said she could not wash the clothes of her six-month-old baby for the last three days as the water supply decreased in their house.
Contacted, Nurul Afsar, project director of Chittagong Water Supply Improvement and Sanitation project, said the level of mud in the Karnaphuli river water increased due to the landslides caused by torrential rain. It also affected the production of Sheikh Hasina Water Treatment Plant and Mohora Water Treatment Plant.
The plants usually produce 14 crore litres and nine crore litres of water a day respectively. But the production decreased to five crore litres and eight crore litres a day, said CWasa sources.
Jahurul Haque, Chief Engineer of Sheikh Hasina Water Treatment Plant, said turbidity in the water of the Karnaphuli went up to 1,530 Nephelometric Turbidity Unit (NTU) — a measurement of concentration of suspended particulates in liquid — on Monday and Tuesday.
As a result, the production decreased to six crore litres, he said. But the situation is improving as it stopped raining. On Friday, it was 1,000 NTU, and the production went up to nine crores, he added.
Normal range of turbidity in the Karnaphuli is 50 to 100 NTU in the dry season, and 200 to 300 NTU in the rainy season, he said. “We can continue our normal production till 600 NTU.”
