Construction Update – Status of Overnight Sewer Monitoring

By November 30, 2017 No Comments

On Tuesday, November 28 and Wednesday, November 29, neighbors may have noticed overnight construction lights and noise from a bypass pump at the AGU site. We sincerely apologize for not issuing advance notice and for any inconvenience this may have caused.

On Tuesday, the construction team removed the top to the 1890s era brick sewer for excavation for the wet well and municipal sewer heat exchange system, a key energy recovery best practice required in the design of this project for the building to reach its goal of net zero energy.

Regulatory requirements necessitated construction lights and a bypass pump to be used overnight to monitor the flow of the sanitary sewer main to prevent an overflow. No work was actively undertaken overnight after permitted work hours.

Monitoring of the sewer was completed this afternoon, and we do not anticipate overnight work on the wet well in the future. However, as an active construction site, should this change or if emergency work is expected, we will be sure to update you as soon as possible.
