Sewer odor in Sadog Tasi, Puerto Rico, Lower Base, Garapan


There will be a sewage odor in the Sadog Tasi, Puerto Rico, Lower Base, and Garapan areas that is expected to continue intermittently throughout the months of February, March, and April, 2021.

According to a Commonwealth Utilities Corp. statement last Thursday, the cause of the sewer odor is due to the reactivation of the aerators in Basin 1 at the Sadog Tasi Treatment Plant and the startup of the digester aerator unit following a drawdown or decanting of excess effluent.

“The temporary clarifier currently running needs to allow additional sludge to build a sludge layer on the bottom of the basin to properly capture and draw the waste sludge from the unit. This process may take up to three months or more depending on the timing of the treatment process changes. As a result, there will be reduced orders and improved effluent quality once it goes operational,” the CUC statement added.

CUC is also working on lessening the odor around the Sadog Tasi Treatment Plant to prevent emission of the odor to the neighboring areas. “We will be looking at alternatives for masking the smell of the treatment process [that] is not hazardous to you, just unpleasant to smell,” it added.
