Tudor Wharf Draft Environmental Impact Report EOEA # 6744 



At Front Street, the sewer line travels 

 westerly along Front Street for 1,600 

 feet. The pipe is 30 x 18 inches. In the 

 vicinity of the Boston Sand and Gravel 

 plant, the line turns northwesterly and 

 travels cross country for 800 feet to the 

 intersection of Rutherford Avenue and 

 Chapman Street. From there, the line 

 travels along Rutherford Avenue towards 

 Sullivan Square. The line enlarges to a 

 31 X 39 inch line for 600 feet and then 

 enlarges again to 37 x 44 inches for 

 another 3,400 feet. At Sullivan Square 

 the line turns northeast, enlarges to 78 

 x 86 inches and crosses under the Mystic 

 River to the pumping station located 

 beside the Edison power plant. From here, 

 the wastewater flows through the 78 x 86 

 inch North Metropolitan Trunk to the 

 Chelsea Pumping Station located near the 

 Chelsea Street Bridge on Chelsea Creek. 

 The North Metropolitan Tunnel carries the 

 wastewater from this point, under Logan 

 Airport to Deer Island for treatment and 

 discharge into Massachusetts Bay. 



The Deer Island Treatment Plant has a 

 design flow of 350 million gallons per 

 day (mgd) . The current average daily flow 

 is 270 mgd. There is sufficient capacity 

 at Deer Island to handle the increased 

 flow (a predicted maximum of 25,163 

 gallons per day) from Tudor Wharf.
