The Town of Billerica has successfully completed the planned power shutdown to allow the installation of heaters on a new switch board. As of 1 pm today we have restarted our tertiary process and it is functioning properly. We are back online in less than 5 hours ( 3 hours less than anticipated). We estimate that approximately 400,000 gallons did not get tertiary treatment, but 100 % of the wastewater passed thru the chlorination process and de chlorination process and passed all tests that we would normally run during the day.
The Town of Billerica permit number is 0101711 and we discharge into the Concord River.

According to the regulation 314 CMR 16.04, I need to add the statement that:
- Precautionary measures to be taken by the public, including the following language “Avoid contact with these water bodies for 48 hours after the discharge or overflow ceases due to increased health risks form bacteria and other pollutants. See Town of Billerica Website for more information on whether specific resource areas, such as bathing beaches are affected”
- A statement that the discharge or overflow consists, or likely consists of untreated or partially treated sewage and waste.
Again, we continued chlorination and treatment of all the flow and it went thru the normal wastewater flow pattern, except the tertiary process. Now with this job completed the WRRF and it's tertiary process is 100% powered during a power failure.
