In March, 2013, a breach was discovered in one of the pipelines that runs under Salem Harbor and carries the Town's sanitary wastewater from Marblehead to the South Essex Sewerage District's (SESD) treatment facility in Salem. The breached line was immediately taken out of service.
An assessment was done to evaluate the condition of the breached pipeline and of a second pipeline located next to it. The pipelines showed extensive deterioration and it was recommended that both the 20-inch line and 24-inch line be replaced.
SESD put the project out for design and began the lengthy process of obtaining the numerous federal, state and local permits that were required before the project could proceed.
The final approval was received and the work commenced in February, 2015.
