I have been trying to help a facility address an issue related to discharge of cooling tower blowdown, where their water source is softened groundwater, and have been informed that the regulators do not look kindly to discharge to septic. Has anybody had any experience with discharge of cooling tower blowdown to septic, and if so, what were the chemicals used in the cooling tower, and were there any concerns about impact on conditions in the septic tank and leaching fields?
Thanks for any help!
