Tiswadi, Ponda water supply hit again as pipe tears
Ponda: A pipeline at Opa Water Works was ruptured by repeated power interruptions, hitting the potable water supply to Tiswadi and Ponda talukas on Saturday. This is the second pipeline rupture in less than a month. On June 26, the same line was ruptured by a 'surge'. A surge means whenever water falls with a tremendous force, the pipeline carrying it bursts near the joints. That occurs when water is being fetched from a river to a treatment plant and the power supply is suddenly cut. The water was released on Saturday afternoon after the ruptured pipeline was welded. However, it will take another day to normalise the supply to households in Panaji and high-lying areas. Sunil Kerkar, an assistant engineer at the Curti water plant, said the rising main pipeline, by which a treatment plant gets raw water from the pumping station, developed a rupture during the intervening night of Friday and Saturday. The rupture was noticed around 1am and the water supply was immediately stopped, Kerkar said. Before the pipeline ruptured, power outages occurred at least three times on Friday. According to Kerkar, a sudden outage of electricity affects the pressure inside a pipeline resulting in a rupture. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Abiti in una casa indipendente?

Sunil Shet, another assistant engineer at the Opa Water Works, said the 750mm mild steel rising main pipeline burst at midnight and repairs were taken up in the morning as the pipeline had to be emptied to facilitate electric welding. Once the repair work was completed, all reservoirs were filled and water released in the afternoon. However, some high-lying areas will receive supply only from Sunday afternoon, he said.

Turbidity of the Khandepar swells after downpour rage
Ponda: The incessant rain in the catchment areas of Khandepar and Kalem rivers during the intervening night of Thursday and Friday has raised the turbidity of raw water in the Khandepar river. The Opa Water Works recorded river water turbidity of 325 NTU (nephelometric turbidity unit) on Friday afternoon. Turbidity refers to opaqueness or cloudiness. Water containing 1mg of finely divided silica per litre has a turbidity of 1 NTU and up to 50 NTU is considered normal. However, data shows that such a high rise in turbidity has been seen far earlier this year as compared to the past eight years. Sunil Kerkar, an assistant engineer of the department of drinking water said the early arrival of the monsoon contributed to the spike in turbidity. Kerkar said that the phenomenon is common during heavy rainfall. He said silt washes off from catchment areas and pours into river water, leading to high turbidity. Sometimes consumers too get turbid water. 'Water is released to consumers only after proper filtration is carried out at Opa water treatment plants,' Kerkar said. After raw water is drawn into a receiving chamber from a river, it flows into sedimentation tanks to allow silt to settle. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Check Out Local Car Deals Near You!

High turbidity levels, however, cost the state exchequer dearly, as several million litres of treated water is used to clean the clogged filters every year. The filters quickly become non-functional due to the density of mining sediments. Follow more information on Air India plane crash in Ahmedabad here .
