  Ron Hidu of the Bangor engineering firm Woodard & Curran said Wednesday that new federal testing standards are expected to result in necessary treatment upgrades at Bar Harbor's pumping station. Some standards are expected to go into effect in January, but others will not for another five years, he said.
  
  The town does not have to filter its water, he said, but beginning this winter it is expected to begin adding chloramides â€" a version of chlorine â€" in order to reduce byproducts that result from other steps of its treatment system. The town has a waiver for having to filter its water because Eagle Lake, which serves as the town's reservoir and is surrounded by Acadia National Park, has fairly clean water.
  
  Additional new standards scheduled to go into effect in 2014 are expected to require the town to add an ultraviolet light phase to its treatment system, according to Hidu.

  All city residents will benefit from the new tank and water line, project manager Ron Hidu of Woodard & Curran Inc., a Bangor engineering firm, said.
  
  "This is a 50- to 100-year asset" for the city, he said."The tank is an appropriate size for today's needs and future needs."
  
  Increasing water quality and pressure are reasons for the two projects, Hidu said.
  
  "It was widely known and recognized that there were several ongoing issues with water quality," he said.

  Sludge buildup has Hermon worried - [Cached Version]

  Using video equipment, investigators two months ago found a thick, black, crusty sludge building up in the pipes, said Ron Hidu, a project manager with Woodard & Curran who addressed the Hermon Town Council.
  
  Hidu estimated the sludge had narrowed the 10-inch pipe to about 8 inches and was causing cavitation, a process where partial vacuums form in a flowing liquid that when they collapse cause pitting and damage to metal objects, such as the mechanical equipment found in the pump station.
  
  An analysis of a sludge samples taken June 3 showed smaller concentrations of grease and oil that would be expected from Dysart's and there were substantially fewer volatile or organic compounds, Hidu said.
  
  Iron compounds accounted for more than one-third of the sample, Hidu said.

  The plant, which is using 30-year-old technology, has single pieces of equipment that have broken leaving no backup for plant operation while repairs are made, according to Ron Hidu, Woodard & Curran project manager.

  Project manager Ron Hidu said he recommended Ellsworth build a new plant even though his "bias going in was to upgrade the existing facility."
  
  Benefits of a new plant include freeing up to 500 acres of waterfront land for future development, said Hidu.
  
  A new plant would eliminate odors in the neighborhood surrounding the existing plant and it would be easier to construct a new plant than make upgrades to the existing plant, he said.
  
  However, it could take Ellsworth a few years longer to fund and build a new plant, Hidu said.
  
  A new plant, which would encompass about 15 acres of land, could be built with room for future upgrades when additional development in Ellsworth warrants greater capacity, according to Hidu.
  
  "You're at about 65 percent of your license on an average day," said Hidu."If you reach 80 percent, you have to do a study of how to expand the plant."
  
  If Ellsworth pursues a new plant, the Maine Department of Environmental Protection might require the city to install a storage tank near the existing facility to handle stormwater overflow from the plant's "illegal bypass" into the Union River, Hidu said.
  
  The illegal bypass has been channeling untreated wastewater into the Union River during storms and other times of heavy flow into the system, prompting the Maine Department of Marine Resources to close the Union River Bay to shellfish harvesting indefinitely.
  
  A consent agreement from the DEP about the illegal bypass and other violations will be finished in a few weeks, said Hidu.
  
  Ellsworth's wastewater treatment plant has other problems.
  
  Issues include the technology the plant uses, which is 30 years old, Hidu said.
  
  The plant has single pieces of equipment that have broken leaving no backup for the plant operation during equipment repairs.
  
  "A lot of the violations have come from equipment breakdowns," said Hidu.
  
  City Manager Stephen Gunty questioned Hidu about the best method for negotiating the consent agreement.
  ...
  "Unfortunately, you're not bargaining from a position of strength," Hidu said.
