Keep an Eye on Wastewater Discharge Volumes

If you are the holder of a Low Flow/Low Pollutant wastewater discharge permit with the Massachusetts Water Resources Authority (MWRA), be sure to keep an eye on the average daily discharge volume.

It is not uncommon for wastewater effluent volumes to be minimal when operations begin at a small biotechnology research and development company. In these cases, facilities are able to obtain Low Flow/Low Pollutant discharge permits with the MWRA due to falling below the 300 gallon per day discharge threshold. As operations grow and processes evolve, wastewater volumes can sneak up and exceed the threshold over time.

The certified wastewater operator that is checking the pH neutralization system on a daily basis should be aware of the need to keep an eye of the average daily discharge. They should also be aware of the person to contact if they notice a trend toward exceeding this threshold.

If you are not the person conducting the daily checks of the system, it might be a good idea to spot check the logs every now and again so you have an idea of what the current effluent volume is.
