SSGC Says Odorant Testing Caused Strong Gas Smell Across Karachi
The Sui Southern Gas Company clarified on Sunday that an unusually strong gas smell reported across parts of Karachi was linked to operational testing rather than a leak in the distribution network. The explanation followed public concern after residents detected the odour in several neighbourhoods and feared that a major pipeline fault might have occurred.
According to SSGC, the smell originated during the commissioning of a new pipeline near Abul Hasan Ispahani Road. The company said its odorisation plants were being tested as part of the process and that a temporarily increased quantity of odorant had been added to the natural gas flowing through the system.
Natural gas is treated with a distinctive-smelling substance so that consumers can quickly detect a possible escape of gas. SSGC explained that the higher concentration used during testing made the smell more noticeable than usual, leading residents in different localities to report what they believed were gas leaks.
The utility maintained that pressure levels throughout its system remained within normal limits and that no leakage had been detected. It urged consumers to remain calm and continue their normal routines, stressing that the stronger smell was a temporary consequence of the testing exercise and not evidence of a system-wide emergency.
Reports of the odour emerged from areas including Mehmoodabad, Manzoor Colony, Karsaz and neighbourhoods near Stadium Road. Some residents complained of uneasiness and breathing discomfort, prompting the company to issue a public explanation as concerns spread across the city.
The clarification is particularly significant because Karachi has previously witnessed serious accidents linked to gas infrastructure. In April, a local court found SSGC negligent in connection with the deaths of two residents in a 2022 gas-line explosion in Orangi Town's Millat Colony and ordered the company to pay Rs30 million in compensation to the affected family.
The case involved a civil claim filed by the victims' daughter, whose lawyer argued that repeated complaints about a faulty line had not been addressed before the explosion. That background has made residents more sensitive to unusual gas smells and has increased public expectations for rapid verification, transparent communication and timely maintenance by utility authorities.
The latest episode also highlights the communication challenges surrounding essential urban services in Pakistan's largest city. A strong odour can generate widespread alarm even when network pressures appear normal, making immediate and detailed updates essential to prevent panic while ensuring that genuine localised faults are not overlooked.
SSGC is expected to continue monitoring the network while the pipeline commissioning and odorisation tests are completed. Further public updates may be required if the smell persists or spreads to additional localities, as residents seek assurance that normal conditions have been fully restored and that every individual complaint is being properly examined.
