Like many coastal New England
Communities, tourism plays a major role in Boothbay Harbor’s
economy. The variation in seasonal population results in much
variation in wastewater flows. Prior to the construction of the
present wastewater treatment facility in the mid-1990’s, the Town
was served by a primary treatment facility. The plant’s location, a
small site in the middle of a residential area, made public
involvement a key factor during the design and construction of the
recent plant upgrade. Because of the severe site constraints,
sequencing batch reactors (SBR) were selected as the secondary
treatment process.
The treatment facility is designed to
provide secondary treatment and disinfection (although the facility
is also capable of removing ammonia nitrogen) to an average daily
wastewater flow of 640,000 gallons. The major components of the
treatment facility include an influent pumping station; headworks
consisting of a bar screen and grit removal equipment; two SBR
tanks; a sodium hypochlorite and sodium bisulfite disinfection and
dechlorination system; an aerated sludge holding tank; a process
building housing pumps, blowers, a laboratory, and a belt filter
press sludge dewatering system; a post-lime sludge stabilization
system; and a septage receiving facility.
Sewer District Superintendent Chris Higgins and two assistant
operators are responsible for the daily operation of the plant, the
wastewater collection system and 18 pump stations. The treatment
facility routinely exceeds 90 percent removal of BOD and TSS.
Wright-Pierce performed the design and construction engineering services. Victor S. Krea, P.E., was Wright-Pierce’s Project Manager on the project.
