Why does my water smell and/or taste like gasoline, diesel, kerosene, paint thinner, or oil?

If there is a gasoline or diesel taste and/or odor to the water from your kitchen tap please contact SUB right away. Please do not drink the water or use it for cooking purposes until you have sought advice from your water supplier.

Oily odors or tastes are usually caused because an oil, such as gas, diesel, kerosene, or paint thinners, has been spilled and has leached into your water supply pipe. If fuel or oil is spilled around, or near to, any underground water pipes, it’s important that they are cleaned up immediately so they don’t contaminate the water. Replacing pipelines can be expensive, so cleaning up the spills before they’re allowed to enter the pipeline can help to minimize costs.

Look for fuel or oil spillages on the driveway or in front of the house i.e. a car or motorcycle leaking oil. These are the most common cause of water contamination as they can get through a plastic service pipe and affect the quality of your water supply.
